Each season, plant diseases may arise that potentially limit crop productivity. There are several maps farmers can use to help track some of the most mobile diseases, including rusts of wheat, corn and soybeans. Rusts do not overwinter in Illinois and consequently blow in from warmer regions each season, according to a University of Illinois Extension news release.
Alessandro Morini, a producer with almost 40 hectares of apple orchards in the Verona province, explains that the damage appeared to be more limited right after the frost, however, 8 days later, the situation does not appear to be good. "Gala and Golden are the varieties most affected. Quantities and quality have dropped and costs are higher.
The ongoing locust invasion poses a threat to the country’s food security with the expected damage in main production areas raising fear of maize shortage this year. Agriculture Principal Secretary Hamadi Boga said there was a high likelihood for these insects, which have invaded the country since December, to damage the young maize crop in the field.
The frosts recorded between March 23 and 26 caused flower and bud damage in peach and apricot orchards, but for now it is not yet possible to estimate the extent to which the production volume will be affected. In addition, further severe cold temperatures are expected in the next few days and frosts may still occur at any time by mid-May.
It is not just the current corona crisis that is proving challenging for fruit growers in Europe. They are facing another issue - night frost. Temperatures have plummeted over the past few nights. Cold nights are also being forecast for the rest of the week. Some Belgian fruit farmers take stock after the first reports of damage start trickling in.
Frost caused serious damage. In some areas of the Bologna and Ravenna provinces and in the central plains in Emilia, temperatures almost reached -6°C. Apo Conerpo president Davide Vernocchi reports "considerable damage to stone fruit: almost the entire apricot production is compromised and peach, nectarine, plum and golden kiwi productions have been heavily damaged.
Aphid migration could be more than a month earlier in some regions this season due to the relatively mild winter, which allowed the pests to over-winter in crops. Monitoring of cereal crops is therefore essential for the rapid identification of aphid flights and effective disease control, with late-sown crops being particularly vulnerable to attack.
The fall armyworm is continuing to spread across North Queensland and has now been detected as far south as Bowen. The pest was first detected in Australia on two Torres Strait islands in January, before reaching the mainland at Bamaga in February. It was then detected on a property in the Gulf country, and in South Johnstone, Tolga and Lakeland.
