Cooperative Extension

An estimated 53 million people in the U.S. turned to food banks and community programs for help putting food on the table in 2021. In recent decades, food banks have adopted policies and practices to make sure people not only have access to food but also healthy and nutritious food. 

Fungal pathogens that cause die-back in grape, avocado, citrus, nut and other crops has found a new host and is infecting conifer trees causing Pine Ghost Canker in urban forest areas of Southern California.

The canker can be deadly to trees.

When it comes to American barn owls, forget spring cleaning. 

The best time of year to clean out nest boxes to ready them for breeding pairs is the fall months of September through November, according to research out of the University of California, Davis, that analyzed nearly a century of banding and other records. 

Scientists, growers, students and Cooperative Extension specialists gathered at UC Davis on Wednesday as part of Vegetable Disease Field Day, hosted by the Department of Plant Pathology.

Two sessions – one in Spanish, one in English – focused on tomato and crop rotation research being conducted in plant pathology fields on campus.

More than 70 people attended the English session, which included stops at three locations and was led by Cassandra Swett, an assistant Cooperative Extension specialist in plant pathology.

Perhaps trees aren’t the only green solution when it comes to cooling urban spaces and reducing energy costs. Honeysuckle, Virginia creeper, pink trumpet and other vines could be a fast-growing substitute in climate-smart cities of the future.

Researchers from UC Davis are leading a nearly $880,000 federal grant to study how vines may provide cooling and shade in Western states in less time than it takes a tree to grow tall.

UC Davis researchers are collaborating with the California Department of Food and Agriculture (CDFA) and UC Agriculture and Natural Resources on a project to help farmers in the state improve their fertilization and irrigation practices. CDFA received $2 million from the USDA for a three-year project that includes sending seven UC Cooperative Extension personnel to the San Joaquin Valley to perform education and demonstration projects, provide on-farm consultation and conduct outreach activities to promote locally appropriate best practices.

The world’s abalone are threatened, endangered or otherwise vulnerable in nearly every corner of the planet. While captive breeding efforts are underway for some species, these giant sea snails are notoriously difficult to spawn. If only we could wave a magic wand to know when abalone are ready to reproduce, without even touching them. 

UC Davis is part of a team of western land grant universities sharing a $7.5 million grant from the U.S. Department of Agriculture to study the effect of wildfire smoke on grapes and wine.

Oregon State University is leading the 4-year project to better understand how wildfire smoke compromises grapes, which poses a threat to the $20 billion wine industry in the United States.

Pima cotton is the predominant variety of cotton grown in California. It’s ideal for making premium fabrics for clothing and bed sheets. But Fusarium wilt disease, caused by a soil-borne fungus, can devastate a cotton crop. It’s responsible for crop losses in several production regions in the U.S. and worldwide. 

Recycling trees onsite can sequester carbon, save water and increase crop yields, making it a climate-smart practice for California’s irrigated almond orchards, finds a study from the University of California, Davis.

Whole orchard recycling is when old orchard trees are ground, chipped and turned back into the soil before new almond trees are planted.
