Italy - A difficult year for cauliflower

"This cauliflower campaign was not the best, as poor weather conditions and heavy rainfall between November and December resulted in a loss of area of at least 30%, caused by flooding of the fields, which blocked harvesting. The product losses affected the medium-late cultivars the most". This is what the president of Coop. Agr La Montagna, Giuseppe La Montagna. "We cultivated 120 hectares of cauliflower for the current campaign, and despite the loss of 30% of the area we were able to sell well on both foreign and domestic markets.” The agricultural cooperative La Montagna was founded in 2008 by three brothers, Francesco, Giuseppe, and Antonio La Montagna, and their uncle Claudio Antonio, boasting a long family tradition of vegetable growers. The farm covers a total area of 300 hectares. The main products of the company are industrial tomatoes, cauliflowers, and potatoes. In addition to these are minor productions such as escaroles, turnip tops, and fennel, ideal for crop rotation. The farm owns 2 hectares dedicated to nurseries, for better management of the cultivation cycles and in order to reduce the production chain. La Montagna's products are all GlobalGAP certified. In addition, harvesting operations are mechanized, except for winter references. "Despite our ability to reduce losses, the winter reference campaign is to leave behind. On the contrary, endives are leading on the market." "For some time now, potatoes are being gradually replaced by industrial tomatoes. As a matter of fact, for the forthcoming campaign around 20 March, we will start transplanting 50% round and 50% long. The supply contract with La Doria, a tomato processing company, with whom we have been working exclusively for about 6 years, is confirmed again this year." "We have been supplying the Polish markets for about ten years now, which is a rewarding business. The most requested products are cabbages from November to date and new potatoes in April/May." "Looking to the future, we would like to be able to extend the zero residue on all our references and we would like to participate in innovative projects that use sensors and decision-making tools to monitor the phytosanitary status and humidity of the soil and, through a specific app, we would know when to intervene," concluded Antonio Iovino, technical consultant.

UK - Flooding making carrot harvest very challenging

The cold weather and persistent heavy rain have been causing problems for UK growers for months now, most of the vegetable production is under pressure. Many regions are flooded including Newark, Nottingham, where FreshGro is based. “It is very difficult; we are struggling due to the flooding,” explains Alan Hunt from the company. “We grow in different areas, some fields are flooded but not all.” FreshGro is still harvesting but it is challenging even where they can get into the fields the wet brings quality issues and labor and transport costs are higher. “There is a lot more soil on the carrots, around 25% so it takes longer to grade them and whereas before we would use two wagons to bring them in, we now need three. We are using more labor and working longer hours. We will most likely have to leave some crop in the ground as well.” It is not all bad news as they still able to fill orders but prices are pre-arranged so profits will be down. This wet season has come off the back of last year’s drought and Alan fears that if it goes from very wet to another drought in the summer the situation will be very bad. “We have not drilled all the new crop yet, so if it comes to a drought situation yields will be low next season. At the moment we are coping, if it dries up soon we will be ok. It is not a disaster yet, but the forecast for the next two weeks is for sunshine and rain, mostly rain.” Other areas such as Suffolk and Scotland have fared better. “We may have to bring some carrots in from Scotland, but the transport is expensive. We don’t want to end the season early as imports from abroad will be more expensive.” Source - https://www.freshplaza.com

Spain - Canary banana plantations heavily damaged by windstorm

The windstorm has caused severe damage to banana plantations in the islands of Tenerife, La Palma, La Gomera, Gran Canaria and, to a lesser extent, El Hierro. It is estimated that about 8,000 plots have been affected by this storm. The north of Tenerife, especially the plantations located in Puerto de la Cruz, is among the most affected areas, with up to 80% of the plants on the ground, and severe damages to those that are still standing. The municipalities of Guía de Isora and Adeje have also been affected by this storm. In this area, where around 90% of this season's fruit had already been harvested, the prospect is that the consequences of the damage will actually be felt in the next season. The island of La Palma has also suffered the consequences of the wind, with places like Tijarafe and Los Llanos recording great damages. In Las Breñas there are also plenty of plants on the ground and considerable defoliation. The plantations in the municipalities of Guía and Gáldar, in Gran Canaria, as well as Valle Gran Rey, in La Gomera, have also recorded severe damages. In the case of El Hierro, the most severe problems have been reported in some facilities in Frontera. All banana farms in the Canary Islands have insurance protecting both production and facilities against all climatic risks. Recommended reporting the damages to the insurers within seven days after the incident, as well as leaving the plot untouched until the visit from an expert, as long as this does not have an impact on the irrigation system or treatments are required.

Australia - Fall armyworm spreads to North West Queensland

A dangerous exotic pest that can destroy up to half a farm's crop has been found in North West Queensland. Fall armyworm is an invasive moth that feeds on hundreds of plant species including many important agricultural crops. The American-native has spread across the world to 65 countries since 2016 and is now in Northern Australia. In Africa and India, it has affected the 50% loss of its maize crop, and in China, it is affecting corn production. After first being spotted in Cape York two weeks ago it has spread to University of Queensland test crops in Georgetown - over a thousand kilometers further west. Queensland's Chief Biosecurity Officer said it was likely well established in Northern Australia and the find prompted a state government-led round table on Thursday with Canegrowers, Growcom, AgForce and AusVegwith Minister for Agricultural Industry Development and Fisheries Mark Furner said a coordinated approach with industry was needed to manage the serious threat it posed. "Thursday's industry roundtable was a productive starting point in the fight against fall armyworm providing a forum to update the industry on the situation, inform them of what the Department of Agriculture and Fisheries is doing in response and discuss what the next steps are," Mr. Furner said. "Key issues identified during the roundtable included identifying suitable control products, determining what industry needs are, monitoring the spread of the pest, and market access." Mr. Furner said traps had been established at Coen, Mossman, Port Douglas, Cairns, the Atherton Tableland and Innisfail and Biosecurity Queensland was establishing a task force to ensure effective and up to date communication with industry. "In the short term, it is important that we work with industry to spread the word about the risk of this pest and also provide advice on control strategies that are available to them," he said. "In the medium to long term, the Department of Agriculture and Fisheries will identify the crops most favored by the pest, assist affected industries to gain access to appropriate chemical controls, help industry manage any pesticide resistance, and research possible biological controls." Katter's Australian Party Leader and Traeger MP Robbie Katter called fall armyworm a potentially "cataclysmic" biosecurity threat, said it was infuriating Biosecurity Queensland was only now reacting to the pest's arrival. "Biosecurity Queensland's failure to prepare for what is coming instead of reacting once it gets here is a clear symptom of the state's weak biosecurity protections, which are a result of continued ignorance from policy-makers in Brisbane," Mr. Katter said. "Biosecurity in Queensland is grossly under-funded, and we are seeing constant reductions in the number of staff who are actually on the ground identifying problems before and when they arrive. "The KAP have warned for many years about an invasive pest disaster such as this one." Source - https://www.barossaherald.com.au

South Africa - Roadmap to a win-win against invasive weeds

Researchers at Wits University in Johannesburg, South Africa, have created the world's first framework, to better guide the management of terrestrial invasive species. By using a big data approach and combining information from the South African National Census of 2011, with the South African Plant Invaders Atlas, the researchers found a way to prioritize targets in the control of invasive species. This will ensure the greatest benefits for both the environment and rural communities. "South Africa spends R1,5 billion per year on controlling invasive species and while the country is really at the forefront alien species control in the world, we still have a wicked problem," says lead author, Dr. Chevonne Reynolds, a lecturer at Wits University. "However, by using our new framework, we can now target invasive control activities by prioritizing localities that are most impacted. Typically, these are the poorest municipalities in the country." Invasive species cost South Africa's economy R6,5 billion in damage from fire, loss of viable land and drinking water. These weeds also threaten our biodiversity and ecosystem services. The main finding of the research, published in the journal Ecosystem Services, shows that poorer rural communities are the most heavily impacted by the negative effects of invasive weeds. "We looked at the livelihoods of people on a national level, what their household income is and how they use natural resources to aid or supplement their daily living need, and then examined how this is affected by invasive species," says Reynolds. While invasive species have both positive and negative impacts on the environment and communities, the team weighed up these trade-offs for a variety of invasive species to find their overall impact on the livelihoods of all South Africans. For instance, people use the fruit of the prickly pear cactus (Opuntia ficus-indica) to supplement their diet and income. However, because it aggressively invades grassland it makes pastures unsuitable for livestock, while also competing for water and other resources. So, overall it has a negative impact on the affected community. The team combined data on household incomes and their use of the natural resources (provisioning ecosystem services) for all municipalities in South Africa, with the distribution data of 57 invasive weeds establish which communities are most affected. "We found that poorer rural communities are the most impacted by invasive species, as these people make the most use of natural resources on a day-to-day basis," says Reynolds. "Their ability to make a living is severely restricted by the invasion of alien species in their environments." Some of the worst affected municipalities are Port St Johns, Nyandeni, King Sabata Dalindyebo, and Mbhashe municipalities all in the Eastern Cape. Stellenbosch and Knysna are the municipalities with the highest diversity of invasive weeds but depend less on natural resources. "What we have done is create a framework for government to direct efforts to eradicate invasive species more effectively, by targeting municipalities where both people and the environment are most at risk," says Reynolds. "Our model can also be used and adapted for other countries with a similar problem, where the novel approach of combining big data with citizen science can provide answers to problems."

India - Loan waiver plan must cover farmers hit by untimely rains

The Maharashtra government''s loan waiver scheme should cover farmers who suffered crop losses due to unseasonal rains in October last year, the opposition BJP demanded in the assembly. Speaking during the Question Hour on availability of crop loans for farmers affected by unseasonal rains last year in Solapur district, Leader of Opposition Devendra Fadnavis of the BJP said the cut-off date for the Mahatma Jyotirao Phule farm loan waiver scheme is September 30, 2019. This will leave out cultivators who suffered crop losses due to untimely rains in October last year, the former chief minister said. "The state witnessed unseasonal rains in October due to which crops spread across 95 lakh hectares were damaged," Fadnavis said, demanding to know if the scope of the loan waiver scheme will be extended till October 31, 2019. Deputy Chief Minister Ajit Pawar said the farm loan waiver implementation, which started this week, will be completed in three months. "We will try to see how farmers benefit," said Pawar, who appeared non-committal on Fadnavis's demand. When Fadnavis sought a clear response to his demand to extend the cut-off date for availing loan waiver benefits, Pawar, who holds the finance portfolio, merely said "suggestion for action". Sudhir Mungantiwar (BJP), a former finance minister, objected to Pawar''s reply. "On one hand, you say you want to make farmers tension -free and on the other hand you are not giving a clear answer on whether you intend to help farmers affected by unseasonal rains," Mungantiwar said. Reacting to this, Pawar said, "appropriate decision will be taken." Early this week, the state government began depositing loan waiver amounts under the scheme, which covers crop debt up to Rs 2 lakh, in bank accounts of farmers. The first list of beneficiaries, released on February 24, covered 15,358farmers. Earlier, replying to the main question regarding crop loans to farmers in Solapur, CooperationMinister Balasaheb Patil said till January 2020, 26,641 cultivators were given loans for the rabi (winter) season. He admitted that farmers in Solapur district were not able to repay their pending loan amounts in time due to crop losses they suffered in natural calamities. Hence, they were facing difficulties in getting fresh crop loans, Patil said. Source - https://www.outlookindia.com

India - Rs 900 p.m. for farmers who switch to "cow-based" farming

The Gujarat government would provide an assistance of Rs 900 per month to farmers who switch to "cow-based organic farming", it said on Wednesday. The announcement was made by Finance Minister Nitin Patel while presenting a Rs 2,17,287 crore budget for 2020-21. The government intends to cover around 50,000 farmers under the scheme, he said. "In recent times, demand for natural farm products has increased because of the damage caused by excessive use of insecticides and fertilizers. To encourage cow-based organic farming, we are launching this scheme with a budget outlay of Rs 50 crore," Patel said. "A farmer shifting to such farming methods will be given an assistance of Rs 900 per month, that is, Rs 10,800 per year to rear cows," the finance minister said. "To avail of the scheme, farmers will be required to use cow dung-based manure and Jivamrut (a liquid fertilizer made from cow urine). It will not only help in improving the fertility of the soil, but also give us organic grains and vegetables. It would also give us a chance to serve cows," said Patel. He also announced the `Mukhya Mantri Crop Storage Scheme'', aimed at preventing crop loss due to unseasonal or excessive rain, cyclones, pests, and other such reasons. It provides for payment of Rs 30,000 to farmers for the construction of storage facilities on farms. No `Non- Agricultural'' (NA) use clearance would be needed for constructing such warehouses.

India - Unseasonal rain and hailstorm damage crops across 3 states

Unseasonal rains with hailstorm over the past two days have caused massive damage to crops at several places in Bihar, Chhattisgarh and Madhya Pradesh, officials said. According to Bihar government officials, rain and hailstorm in parts of south and north Bihar adjacent to Uttar Pradesh on Tuesday damaged flowering and fruiting oilseed, pulses, vegetables, tobacco crop, and blossoming mango orchards. In some parts of Kaimur, Rohtas, and Aurangabad, a hail of up to 20mm was recorded within a few hours on Monday and Tuesday, officials said. Strong winds with speeds of up to 40 km per hour resulted in damage to mango trees in several areas. “We are finished,” said Amit Singh, a farmer of Badhauna village in Vaishali district. “The Rabi crop was our last hope for survival. Heavy rain in November, December and January destroyed our paddy crops.” Umesh Kumar Mandal, joint director (agriculture), said rain and hailstorm may have harmed the flowering pulses and oilseed crops and the fruiting crops to some extent. “The government would surely provide compensation to the farmers,” he said. In Madhya Pradesh, hail damaged crops in at least 10 districts, including Mandla, Dindori, Katni, Satna, agriculture department officials said. Agriculture minister, Sachin Yadav, said a survey of the damaged crops is going on. “It is only after the survey that the extent of the damage can be ascertained. The government stands by the farmers and it will extend assistance to them based on the survey report.” In Chhattisgarh, the state government instructed district collectors on Wednesday to find the estimate of the crop loss. Heavy rain and hailstorm have affected crops in Surguja, Bilaspur, Durg and Raipur region, officials said. Indresh Pandey, a farmer, said all farmers of Raipur are badly hit as crops of chickpeas (gram/chana), wheat, and tomato had been damaged. “I have grown wheat, tomato, and chickpeas on my 10 acres of land in Sejbahar village, which is of no use now,” said Pandey. Agriculture minister, Ravindra Choubey, said chief minister Bhupesh Baghel has instructed all collectors to assess the damage and compensation will be paid to all the farmers.

UAE - First locust swarm exterminated

Small groups of desert locusts were spotted on Abu Dhabi's Dalma Island, but they were exterminated as soon as the sighting was reported, authorities have said. The Abu Dhabi Agriculture and Food Safety Authority (Adafsa) confirmed that its team surveyed a 6sq km area of farmland on the island and got rid of the small gatherings of locusts through fumigation. It was the first locust swarm found in the country, but no significant damage to crops was reported, the authority said. The control team at the Dalma Island Centre, in cooperation with the Al Dhafra Municipality, ensured that pesticides were sprayed across the area where the pests were found. Agricultural authorities in Abu Dhabi assured that they are fully prepared to "confront any desert locust swarms coming from the breeding areas in the Arabian Peninsula and the Red Sea coasts". Surveys will continue across the Capital, especially in border areas where swarms are likely to cross. Municipalities have also intensified forest survey operations and monitoring in other areas. Desert locusts have invaded parts of Saudi Arabia and Yemen since the beginning of February, posing a threat to the agriculture sector. Millions have also swarmed into Ethiopia, Kenya, and Somalia - the worst infestations in decades. Dr. Mohammed Salman Al Hammadi, acting director of communication and community service at Adafsa, said: "All measures are in place to control the desert locusts using safe and recommended pesticides. The authority is working closely with governments and international bodies monitoring locust movements to ensure swift action and reduce potential crop loss." Source - https://www.khaleejtimes.com

Canada - 2020 Crop Insurance program announced

The Governments of Canada and Saskatchewan announced the 2020 Crop Insurance Program Feb. 25. This year’s program expands coverage to include changes to the soybean, organic and vegetable insurance programs, as well as new rules for re-entering the program. The Saskatchewan Crop Insurance Corporation (SCIC) works closely with industry partners when making changes to the program each year, said Shawn Jaques, president, and CEO of the organization. “We want to make sure that our program remains relevant to the changing agricultural landscape,” he said. “For example, soybeans are being grown more commonly across the province, so it made sense to expand that coverage to the entire province.” Coverage for soybeans will also be available on irrigated land and producers can now use their insured history rather than the regional average. As for coverage and premiums, those elements remain in producers’ favor. “We have the second-highest coverage on record at an average of $224 an acre and producers will see a premium decrease. On average premiums, will be $7.40 per acre, down from $8.61 in 2019,” Jaques told Farms.com. The 2020 program will now include organic premiums and coverage based on data from organic customers in Saskatchewan. “Previously, organic insurance was based as a proxy on our regular crop insurance program or the commercial acres. Now that we have enough data available from organic producers, we're able to offer organic insurance that's tailored to the risks on organic farms,” said Jaques. SCIC worked with the Saskatchewan Vegetable Grower’s Association to enhance the Vegetable Acreage Loss Insurance Program by adding asparagus as an eligible crop, extending fall cut-off dates and updating the insured value of vegetable crops to better reflect production costs. SCIC has also made the process easier for producers looking to re-enter the program. “You now have up to seven years to re-enter the program and you get to retain your yield coverage and any experience discount or surcharge you had when you left the program,” Jaques explained. Producers with 2019 crops still in the field should remember the Wildlife Damage and Compensation Program, Jaques added. “If producers notice damage in the spring prior to harvesting, give us a call. We'll send an adjuster to complete the inspection. And that compensation program is available to all producers whether or not they belong to crop insurance,” he said. In the coming days, producers should watch their mailboxes as SCIC is sending out personalized information, Jaques said. “No two farmers are alike. So, I would encourage producers to look at the options that are available and how they could work for their farms,” Jaques said. If producers have questions, they can contact SCIC by phone, online or stopping in to a local office. Source - https://www.farms.com

UK - Origin Enterprises cuts full year outlook due to wet weather

Shares in Origin Enterprises slumped over 6% today after it said it was cutting its outlook for the full year to the end of July following the impact of "prolonged and challenging weather conditions" in Ireland and the UK. Origin said that as outlined in a trading update in November, significant rainfall in the UK from September to November meant that the total area for winter crops was expected to be 25% down on the previous year. The agri-services group said today that after further heavy and sustained rainfall from December to February, it now expects the total winter planted area in the UK will be at least 40% lower year on year. "Autumn/winter rainfall has been at its highest level in 30 years, with more than double the number of continuous days rainfall compared to the prior year and the fifth wettest on record," the company stated. It also said it expects a greater area will now transfer to spring cropping, with a consequential lower investment spending by farmers and growers on agronomy services and crop inputs. "With the extent of the shortfall in winter cropping in addition to the poor establishment of already sown crops, the total planted area for the 2020 financial year is expected to be circa 10% lower year on year, compared to the anticipated 2% reduction at the time of the Q1 trading update," the company cautioned. "The impact on Ireland and UK performance of the adverse conditions experienced to date together with the challenges associated with an anticipated large increase in spring cropping means that it is expected that group operating profit and adjusted diluted earnings per share for the full year will now be significantly below the current range of analysts' estimates," it added. Origin said the outlook for the spring planting season remains uncertain. "Consistent with prior years, we will be in a better position to provide a meaningful update on full-year guidance at the time of the third-quarter trading update on 17 June," it added.

USA - Aid coming for Georgia farmers pummeled by Hurricane Michael

More than 500 days after Hurricane Michael flattened crops and livelihoods in southwest Georgia, a fresh infusion of emergency aid money is on its way. Top state officials on Wednesday announced a $347 million grant program aimed at farmers and landowners in 95 south Georgia counties who sustained major losses during the historic storm, which made landfall in October 2018 as a Category 5 behemoth. Agriculture Commissioner Gary Black said the program will cover crop and equipment losses, as well as damage to timber and pecan orchards that are typically excluded from federal aid programs. Trees sustained generational damage during the storm, costing farmers millions in lost future income. It takes trees years to become fully productive once they’re replanted. “We thought it was very important to have a program that would answer the challenges for timber, pecans and all of those commodities,” Black told The Atlanta Journal-Constitution. “They had such extraordinary losses.” The grants will also cover damage to poultry, beef, dairy, fruit and vegetable crops, as well as some destroyed irrigation systems, farm structures, and uninsured equipment. Farmers can apply for the aid through a new website set up by the Georgia Department of Agriculture for three weeks beginning on March 18. Black estimated the money will begin flowing this spring. The money comes from the $19 billion emergency spending package Congress passed in June after nearly a year of partisan brinksmanship over aid for Puerto Rico. The U.S. Department of Agriculture, led by former Georgia Gov. Sonny Perdue, began releasing $3 billion in relief this fall to farmers reeling from natural disasters across the country. Cotton and peanut farmers have been eligible for that funding, but multiple farmers told the AJC this week that the money has been slow to trickle down to southwest Georgia. At a Wednesday press conference surrounded by state lawmakers and agriculture officials, Gov. Brian Kemp directed his comments toward still-hurting farmers. “We know this was a generational event, and it will take a long time to recover,” Kemp said. “But we continue to fight for you.” In the months after the funding cleared Congress, Georgia officials — advised by a task force of rural businessmen, commodity groups and the University of Georgia’s Cooperative Extension — began working with the USDA to set the guidelines for the block grants, which had long been championed by Black and Gov. Brian Kemp. UGA previously estimated that Michael caused upwards of $2.5 billion in agricultural damages to the state. “The health of the rural community is riding on us doing a very good job,” Black said. Dozens of federal agencies are divvying up the rest of Congress’ disaster relief money, which will go toward repairing roads, housing and other damaged infrastructure across the country. Bainbridge agribusinessman Tommy Dollar, who operates a farm with his son and served on Black’s task force, said farmers in his corner of the state have faced countless setbacks in the 16 months since Michael hit. “To have lost it all in one month in 2018 and have to wait 500-something days before they get the money has been very hard mentally and physically on a lot of people,” he said. “But it feels good today.” Source - https://www.ajc.com

Africa - Local genetic adaption helps sorghum crop hide from witchweed

Sorghum crops in areas where the agricultural parasite Striga, also known as witchweed, is common are more likely to have genetic adaptations to help them resist the parasite, according to new research led by Penn State scientists. Changes to the LGS1 gene affect some of the crop’s hormones, making it harder for parasites to find in the soil, at least in some regions. The changes, however, may come at a cost, affecting photosynthesis-related systems and perhaps growth. The new study by an international team of researchers appears online Feb. 11, in the journal Proceedings of the National Academy of Sciences, and may eventually inform strategies for managing the parasite. Witchweed is one of the greatest threats to food security in Africa, causing billions of dollars in crop losses annually. It has a variety of hosts, including sorghum, the world’s fifth most important cereal crop. “We wanted to know if sorghum plants in areas with high parasite prevalence were locally adapted by having LGS1 mutations,” says Jesse Lasky, assistant professor of biology at Penn State and senior author of the paper. “We often think about local adaptation of agricultural crops with regard to factors like temperature, drought or salinity. For example, if plants in a particularly dry region were locally adapted to have genes associated with drought-tolerance, we could potentially breed plants with those genes to resist drought. We wanted to know if you could see this same kind of local adaptation to something biotic, like a parasite.” The researchers modeled the prevalence of witchweed across Africa and compared the presence of LGS1 mutations thought to confer some resistance in sorghum. They found that these mutations were more common in areas with high parasite prevalence, suggesting that sorghum plants in those areas may be locally adapted to deal with the parasite. “The LGS1 mutations were widespread across Africa where parasites were most common, which suggests they are beneficial,” says Emily Bellis, a postdoctoral researcher at Penn State at the time of the study and first author of the paper. Bellis is currently an assistant professor of bioinformatics at Arkansas State University. “But these mutations were not very common, and nearly absent outside of parasite-prone regions. This indicates that there may also be a cost, or tradeoff, to having these mutations.” To better understand the effects of the LGS1 mutations, members of the research team at Corteva Agriscience used CRISPR-Cas9 gene-editing technology to replicate the mutations in the lab. The loss of LGS1 function did appear to confer resistance to witchweed in their experiments, as parasites had germination rates that were low or even zero, suggesting the parasites were not as successful at finding the crop to reproduce. But parasites collected from different geographic locations in Africa were affected in different ways. “Germination of parasites from a population in West Africa was effectively shut down in both nutrient-rich and nutrient-poor conditions, but we still saw germination up to about 10% for a population in East Africa when nutrients were limited,” says Bellis. “That is definitely an improvement, but there can be thousands of parasites in the soil, so even 10% germination can be problematic, especially in the smallholder farms where these crops are predominantly grown.” LGS1 mutations are known to affect strigolactone hormones that sorghum releases from its roots. Because the parasite uses these hormones to find sorghum, altering the hormones makes the plant mostly invisible to the parasite. But strigolactones are also important for communication with mycorrhizal fungi, which play an important role in the plant’s acquisition of nutrients. The new study found that loss of LGS1 function in the modified plants also affected systems related to photosynthesis and subtly affected growth. “It may be that plants with LGS1 mutations are better at hiding from the parasites, but are less productive,” says Lasky. “This potential tradeoff might explain the relatively low prevalence of these mutations in sorghum across Africa.” The researchers also identified several mutations in other genes that are related to parasite prevalence, which might reflect local adaptation. The researchers plan to investigate these genes — some of which are involved in cell-wall strengthening, to see if they may also confer resistance to the parasite. “We eventually would like to look at other agriculturally important host plants of Striga in Africa to ask similar questions,” says Lasky. “If we do indeed see local adaptation to the parasite and find genes that confer resistance with few tradeoffs, we may be able to capitalize on that from a management perspective.” Source - https://seedworld.com

Kenya - Locust swarms leave empty fields in the wake

Retired army officer Francis Mugwika has fought and won many battles. But he has lost the fight against locusts not once, not twice, but thrice in just two months. This past week we found an inconsolable Mr. Mugwika on his 12-acre farm in the rocky Kathuri hamlet in Tharaka North. His green grams and millet were first attacked in early January. The pests that entered the country on December 28 and have now covered 20 counties would, in their second and third visits, wipe out the entire crop. For a model farm, the loss could not have been more devastating. Now, what remains are browning fruitless stalks that seem to mock his efforts. A visit by Agriculture Cabinet Secretary Peter Munya and Governor Muthoki Njuki on February 17 offered him a glimmer of hope that was soon dashed. “County officials told us not to disturb the swarms so that they could be sprayed to prevent them from spreading to other farms. They told us that they would compensate us for offering our farms as a sacrifice to save others. But nothing has come of the promise,” said Mr. Mugwika. He said that had he been allowed to fight the pests he would have saved some crops. The loss is all the more shattering as it came following a prolonged drought. “It hadn’t rained properly for three years and we were hopeful. We bought seeds at a very high price. They have finished me and I now leave everything to God,” he lamented. He was expecting 12 bags of green grams, which would have gone for at least Sh100 a kilo, and 36 bags of millet, which is sold at Sh40 a kilo. “We had never seen anything like it before. We saw them at 6 pm and began beating tins, sulfuric and anything we could lay our hands-on, but they were too many. Help came too late,” he said. The voracious pests did not spare even shrubs, a valuable goat feed in the semi-arid land. “We had been told that an aircraft would come to spray them but it never came. We were relying on the crop for everything. We plead with the government to compensate us.” So virulent was the second attack that help from pupils of a nearby primary school could not save the crop from the ravenous pests that eat their own weight in a day. “Every time the vegetation tries to sprout it is nipped in the bud by another attack,” Mr. Mugwika said. The eggs laid during the first visit have hatched and the pests are approaching maturity. During the tour, the Nation team spotted a few hoppers. They are brown and markedly different from the mature yellow ones. In the fertile plains of Mwingi West in neighboring Kitui County, we visited Thitoni in the aftermath of spraying, which farmers lauded as successful. Thitoni location chief Josephine Mathenge told the Nation that three swarms of locusts landed in the area on Monday last week and were promptly sprayed. “We called agricultural officers who sprayed them. Some died while others flew towards Machakos County,” Ms. Mathenge said. She said that the chemicals work well and refuted claims by some residents that government efforts were ineffectual. In Uiini, Kilela and Mbaunzo villages, which were attacked, much of the maize and green grams remained untouched. Ngula Mwendwa, 83, said the 1954 locust invasion was worse than the present attack. “They died immediately after they were sprayed. Then the next day there was an awful smell in the air,” he said. The county government of Kitui has singled out Tharaka and Tseikuru wards in Mwingi North as the most affected with Mgatra, Ngongoni and Gacigogo villages being the worst hit. Breeding sites have been identified in Kyuso and Tseikuru wards. During our visit on February 19 and 20, Dr. Wathe Nzau, the deputy governor, explained that spraying had been halted because of “normal servicing” even as skeptical experts suspected shortage of resources. In Central Kenya, the pests descended on farms in Mukurwe-ini, Nyeri County, but the damage was minimal. A Nation team that toured the region to assess the extent of damage caused by the pests met desperate farmers who said they used all in their means to chase the insects away. “They are like lawnmowers. They ate my napier grass and sweet potatoes to the ground,” said Ms. Mary Gathoni. She said that had it not been for the trees in the forested Mukurwe-ini, the effect on coffee, the region’s most important cash crop, would have been devastating. But experts reckon the insects would not have stayed for long in the cold environment. In Embu, intensive spraying was ongoing in Mbeere South where the pests have attacked mainly pasture and shrubs sporadically since January 24, with Kiambere and Mavuria wards being the most affected. A situation report presented to the County Assembly by the Agriculture executive said locusts destroyed mainly acacia trees. “The locust control unit responded quickly and sprayed using fenitrothion,” says the report. Surveillance team It estimates that little was lost because much of the crop had been harvested by the time of the attack. “The only crop affected was cowpeas. We estimate to have lost about 50 hectares, green grams (25), sorghum (20), napier grass (six), tomatoes (six) and acacia (200). The report also refers to a “peculiar case at Isako where one woman was affected by the pesticide and was rushed to a near dispensary”. No effects on livestock were reported. The executive formed surveillance teams to monitor the pest and speed up response, says the report. The national government trained and deployed 40 National Youth Service personnel to assist in spraying chemicals. “The county has sensitized the community on the use of integrated locust control methods (use of smoke, noise, and throwing stones at swarms), the report says. Dr. Timothy Njagi of the Tegemeo Institute of Agricultural Policy and Development, a think tank, warns that while there have been little effect on crop growing areas, arid and semi-arid lands have suffered huge losses. But it has not been all gloom. The Swahili saying vita vya panzi neema ya kunguru (a hoppers’ fight is a raven’s gain) might as well explain the windfall for dogs in locust-infested areas. The canines, most of which have to make do with leftover food in most rural homes, have had a field day. Yet despite all evidence of the richness of the insects as a source of protein for humans, the culture has not caught on in Kenya and the food goes to waste. In a hilarious video doing the rounds on social media, a man purportedly from western Kenya laments that the food is being sprayed indiscriminately yet he and his friends would have been hired to go and clear them. In reality, though, there has not been any serious uptake from Kenyans. Dr. Muo Kasina, the Entomological Society of Kenya chairman, says that a lot can be saved if the government adopts the consumption of locusts as a control measure. “The government needs to be convinced about this. It has not been discussed by the government as major food and feeds source,” he said in an interview. “It is a great protein supplement for animal feeds. I am happy about reports of Kenyan business experts willing to buy locusts for feeds. They are superfoods and feeds.” The latest regions to be invaded by the pests are Bungoma, Baringo, and West Pokot. What complicates locust control is that while the pest is suited for harsh conditions, it takes advantage of good conditions to breed and thrive. Three cyclones — two in 2018 and one last year — are responsible for the explosion of the pest’s population in the Middle East and the Horn of Africa. A cyclone from the Indian Ocean hit a remote area of the Arabian Peninsula known as the Empty Quarter, and the arising wetness gave the huge sandy area excellent conditions for egg-laying and breeding. Scientists now predict that the cyclones will become more frequent as rising sea temperatures supercharge storms. Insecurity in Somalia and Yemen, lack of resources and safety concerns in densely populated areas hamper a more robust control drive that experts say is needed to prevent the situation from becoming a catastrophe. In Kenya, the pest is breeding fast and is expected to multiply 20-fold by crop planting time next month. To deal with the problem, experts urge the upscaling of control efforts. So far, the UN says $22 million (about Sh2.2 billion) of the $76 million (about Sh7.6 billion) it needs to combat the menace has been either received or pledged. Yesterday, Agricultural Research Principal Secretary Hamadi Boga said NYS personnel would be sent to other affected regions after deployment in Isiolo and Samburu. “Their role is mainly ground control. Fifty to 100 youths will be trained in every county to support them,” Prof Boga said. Source - https://mobile.nation.co.ke

Africa - How changes in weather patterns could lead to more insect invasions

Outbreaks of insect pests and insect invasions are on the rise on the African continent. Currently, several African countries – including Kenya, Ethiopia, and Somalia – are dealing with one of the most devastating outbreaks of desert locusts. This comes after recent fall armyworm invasions which affected more than 44 African countries. Countries also grapple with more localized pest invasions of insects like the South American tomato moth and maize stem borers. Many countries suffer from a lack of food because the insects can consume, or destroy, huge amounts of crops. Just five invasive insect pests are estimated to cost the African continent US$1.1billion every year. Insect-pest related crop losses and pest invasions are projected to increase as the climate changes. Projected changes include changes in temperature – with many regions becoming warmer– and the amount of precipitation. Insects thrive in warmer temperatures. Studies show that insect-pest related yield losses for maize, rice, and wheat are expected to increase by between 10% and 25% for each degree Celsius of warming. The impact will be huge. These crops are the three most important crops in the world, accounting for 42% of calories eaten. Broadly, there are two explanations for why there’ll be more insect invasions: because the changing weather modifies insect traits and because the changing weather is having an impact on their food, natural enemies and predators. Insect traits A changing climate causes changes in temperature. This has a huge impact on insects because they are cold-blooded animals. This means that their growth, development, and life-cycles are regulated by temperature. Consequently, when temperatures are warmer or colder than the norm, this directly affects their development, growth, reproduction, and ultimately population numbers and distribution. As temperatures rise, the insect’s metabolism speeds up. Because they are burning more energy, they consume more, develop faster and larger, suffer less mortality, reproduce faster and lay more eggs. The end result is an increase in populations, and consequently, more crop damage. A changing climate will also affect rainfall patterns. We are already seeing this with more incidents of droughts and floods. These changes affect the interactions between insect pests, plants, and their natural enemies. For example, there is substantial evidence showing that drought stress increases the number of crop plant-eating insects. There’s a bit of contention as to why this is the case, but the plant stress hypothesis suggests that insect performance increases with plant stress because of the plant’s level of investment in its chemical defenses decreases. Changes in the weather can also affect the territory that insects live in. There’s compelling evidence that insect distributional ranges are changing. As warming happens, insects are moving into new territories and exploring new habitats. They do this to find food and to escape competition and natural enemies. Extreme conditions – like drought and floods – also alter the nutritional value of plants. Faced with the problem of a less nutritious plant, insects consume more plant tissues to get the number of nutrients they need. Natural enemies Climate change may also alter the interaction of insect pests and their enemies. These may be natural predators such as ladybird beetles, which eat aphids. They can also be introduced to control pests; Cotesia flavipes, for example, is an insect that has been introduced in various countries to control stem borers. In a perfect world, natural enemies should be abundant when crop plants are under pressure from insect pests. But the ability of natural enemies to find the insect pests depends on their ability to tolerate changing weather conditions and how well they can move. And when they find the insect pests, other factors – like the size of the insect host – are important. For instance, parasitoids (insects whose larvae live as parasites that eventually kill their hosts) develop inside the host. If the host insect is too small, there won’t be enough food for the larvae to grow and hatch. This may determine whether they stay to protect plants from the pests. These are some of the key findings of the impact of climate change on insects. There is still a lot to be discovered, though. More research needs to be done to develop a clear understanding of how climate change, directly and indirectly, affects insects, to help us predict what invasions could happen, and where.

USA - Potato prices increasing due to $10 million loss of crops in Skagit Valley

Prices of many potatoes are going up at the grocery store. That's due largely to up to $10 million in recent losses of potato crops in the Skagit Valley. It's all about supply and demand. This shortage of crops has increased the prices of these potatoes for people at the grocery store. This is all according to agricultural expert Don McMoran at WSU. Jerry Nelson has farmed in the Skagit Valley for more than 50 years. Growing red, yellow, white and purple potatoes is his passion. "This is probably for me, maybe because of my age, one of the most stressful years – the most stressful one I’ve ever had," Nelson said. Nelson guesses that he lost up to 12 percent of his potatoes this year due to the relentless rains early in the fall. "This is about as hard on me as I’ve ever gone through in the fall," Nelson said. Across the Skagit Valley, experts said farmers were unable to harvest an estimated three square miles of potatoes; those losses are valued between $5-10 million. McMoran said it is normal for farmers to not harvest some land every year, but a loss of this size is rare. Meanwhile, Nelson wouldn’t be surprised if that number was 15 million or higher. "You can’t help but go through your mind, 'do I replant again next year?'" Nelson said. Potatoes typically bring in roughly $60 million to Skagit County growers every year. This industry provides a lot of jobs in the area. "Our season is going to be shorter and so it’s going to affect the labor force," Nelson said. These losses to local potato crops may hit other businesses, too. We talked to the owner of the Trumpeter Public House restaurant in Mt. Vernon -- he said he may need to get his potatoes elsewhere for now -- until the next crop is harvested. "They’re some of the best in the world," said restaurant owner Paul Springer. "I don’t think, we can source from other areas, but the quality just isn’t as good as what comes out of the Skagit Valley." Source - https://komonews.com
