Italian ryegrass is a major weed in orchards, vineyards, field crops, and fallow fields of California (Figure 1). Several different herbicides are used to control ryegrass and had been effective in reducing infestations until resistance evolved in many populations following repeated use of the herbicides. To date, resistance to glyphosate, paraquat, and some ACCase and ALS inhibitors has been confirmed …

The 2Blades Foundation and collaborators at the University of Minnesota, Kansas State University, and the John Innes Center will study wild emmer wheat to discover genes that can help farmers combat devastating wheat rust diseases which are estimated to cost farmers and consumers nearly $3 billion each year. The United States Department of Agriculture’s National Institute of Food and Agriculture …

UC Riverside scientists have solved a 20-year-old genetics puzzle that could result in ways to protect wheat, barley, and other crops from a devastating infection. Ayala Rao, professor of plant pathology and microbiology, has been studying Brome Mosaic virus for decades. Unlike some viruses, the genetic material of this virus is divided into three particles that until now were impossible …

Fields of wheat are so associated with the U.S. that they’re featured in the song America the Beautiful as “amber waves of grain.” But those amber fields face a big threat: Russian wheat aphids. As their name suggests, these aphids hail from Eurasia. These invasive pests first made their way to Texas in 1986. They’ve since spread to many states …

While most Californians are staying home to slow the spread of the novel coronavirus, California farmers, farmworkers and other agricultural professionals are out in the fields and packing houses working to produce food. With increased demand for personal protective equipment, or PPE, to protect against COVID-19, these essential workers are facing shortages. Agricultural commissioners in 28 counties are hearing from …

California employers are required to establish and implement an Injury and Illness Prevention Program (IIPP) to protect employees from all worksite hazards, including infectious diseases. This guidance contains information, recommendations, and requirements for agricultural employers on how to update their IIPPs to include preventing the spread of COVID-19 in the workplace. This guidance does not introduce any new legal obligations, but because COVID-19 …

Agricultural Research Service (ARS) scientists and their colleagues have discovered a gene that can be used to develop varieties of wheat that will be more resistant to Fusarium Head Blight (FHB), a disease that is a major threat both overseas and to the nation’s $10 billion annual wheat crop. A paper reporting the discovery and the cloning of the gene, …

U.S. Secretary of Agriculture Sonny Perdue today announced a collaboration with the Baylor Collaborative on Hunger and Poverty, McLane Global, PepsiCo, and others to deliver nearly 1,000,000 meals to students in a limited number of rural schools closed due to COVID-19:  “Feeding children who are affected by school closures is a top priority for President Trump and this Administration. USDA is …

Alfalfa is often called the “Queen of the Forages” due to its high yield, feed quality for ruminant animals, nitrogen fixation and pollinator habitat among other environmental services. But this royal member of the legume family is no match against the host of microbes that cause the disease complex known as “crown rot.” Chemical controls aren’t effective against crown rot, …
