Cherry growers are trying to stop the spread of a disease that can decimate their crops, known as “little cherry disease.” Trees with a little cherry disease produce a small, pale, lower-sugar fruit that can’t be sold. Northwest Cherry Growers, an industry group, expects the loss of 2.5 to 3 million boxes of fruit this year because of the disease.
Lettuce is one of the top ten vegetables cultivated in the United States and for good reason. Romaine, iceberg, leaf and butterhead types of lettuce are staples in refrigerators around the world. But the crop has experienced devastation nationwide with the emergence of the deadly Bacterial Leaf Spot (BLS), a disease caused by a pathogen known as Xanthomonas campestris pv. vitians (Xcv).
Banana growers in Rungwe district - in Tanzania’s Mbeya region - have been called upon to report whenever they discover and disease infecting the crop so as to increase production. The advice was issued by a researcher on fruits and vegetables from Tanzania Agricultural research Institute Uyole centre (TARI-Uyole) Daud Mbongo when speaking to farmers in Kisondolea Ward in Rungwe district.
Louisiana vegetable growers are beginning to see problems from southern bacterial wilt. This phenomenon is one of the most serious diseases of garden crops including tomatoes, eggplant and bell peppers, caused by the soil-borne bacterium Ralstonia solanacearum. Raj Singh, LSU AgCenter plant doctor: “In addition to solanaceous vegetables, the bacterium can cause disease in a wide range of ornamentals.
While citrus is a major fruit crop of Pakistan, with a large share in exports of horticultural produce - the annual production of citrus in Pakistan was about 2.5 million tons in 2018 - at this point in time, yield losses of about 22% for kinnows, 25–40% for sweet oranges, 15% for grapefruits, 10% for sweet limes, and 2% for lemons are reported.
Engineers from the Massachusetts Institute of Technology have developed a precision injection system for plants to potentially help orange, olive and banana crops threatened by diseases. The new system uses silk-based biomaterials to fabricate a microneedle-like device, which can inject nutrients, antibiotics or other pesticides into plants' circulatory systems, according to a study describing the system, published this month in the journal Advanced Science.
The North Queensland government and the Australian Banana Growers' Council have teamed up to jointly fund and deliver a program that is designed to protect Australia's $600 million banana industry. To that end, a new board, tasked with overseeing Queensland's Panama TR4 Program for the next three years, has met for the first time.
A team of experts at Penn State has investigated the long-term impact of soybean diseases in the United States. The study revealed that soybean diseases led to more than $95 billion in losses from 1996 to 2016. Paul Esker is an assistant professor of Epidemiology and Crop Pathology in the Department of Plant Pathology and Environmental Microbiology.
Growers of Vidalia onions battled too much rain this winter, causing some losses of the signature Georgia crop. Now, as the official first day of shipping arrives Thursday, farmers are keeping an eye on the coronavirus. Many are worried about how the pandemic, which over the course of five weeks has disrupted almost every phase of ordinary life, will affect the 2020 season.
Growers will be able to identify wheat diseases up to five times faster than conventional crop walking, thanks to the launch this spring of a new mobile phone app which uses drone imagery. The app, named Skippy Scout and developed by technology pioneer firm Drone Ag, aims to pinpoint diseases such as yellow rust and septoria tritici earlier in a crop’s development.
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.
