At first glance, Orobanche ramosa looks like an interesting blossoming plant, one that could add a unique flair to flower arrangements. But it’s a parasitic weed that attaches to roots, sucks out nutrients and is threatening California’s lucrative $1.5 billion processing tomato industry.

Avocado oil has become a popular choice for many people in recent years because of its heart-healthy benefits and versatility in cooking. However, not all avocado oil products on store shelves are created equal. Some products are labeled as “pure” avocado oil when they contain other oils or additives. No enforceable standards defining the chemical and physical characteristics of avocado oil exist yet.

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.

UC Davis researchers are providing more insight into how grape skins and seeds, which usually go to waste during the making of chardonnay wine, may be a valuable and healthful ingredient in new food products.

A review paper published by the Journal of Agricultural and Food Chemistry outlines how chardonnay marc can serve as a model for developing plant-based natural product food ingredients, and perhaps make upcycling agricultural byproducts relevant to other post-harvest processing scenarios.

Due to severe water shortages, rice acres planted in California plummeted by 37% from 2021 to 2022, according to numbers released recently by the U.S. Department of Agriculture's National Agricultural Statistics Service. But now, thanks to University of California researchers, growers have a new tool they could potentially use to cope with droughts and other environmental and socioeconomic changes.

Native gray wolves are returning to rugged rangelands throughout the west, raising risk for the millions of cattle who graze there. In the California counties of Lassen, Plumas and Siskiyou, many ranchers say their cattle are being stalked by wolves and show signs of stress, such as fewer pregnancies and lower birth and weaning weights. That comes with a cost.

One in five students in the United States will not earn a high school diploma — and young adolescents who fall behind in school risk never catching up, leading to unemployment, poor health and poverty, research has shown.

But a new University of California, Davis, study of intermediate school students in urban California and New York shows promise for underachievers. Researchers found that early intervention with teachers, training students that intelligence is malleable and achievable, caused struggling students to flourish and improve their grades.

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.
