UC Davis researchers explore electrical weed control as an alternative to herbicides. The project uses a tractor equipped with an electrical generator to deliver electrical energy to weeds, damaging their cells and causing rapid death. The three-year study assesses the machine's effectiveness, its impact on crop safety, and soil health.
Organic legumes already developed by postdoctoral researcher Travis Parker are prized, especially in Southwest cuisine, for their colorful patterns, flavor and texture. Parker’s new work seeks even better, more beautiful beans for arid climes. The Department of Plant Sciences geneticist has received a boost for his work with a $20,000 grant, funded jointly by the Organic Farming Research Foundation and the Foundation for Food and Agriculture Research.
Downy mildew makes those dry, tan-colored spots on spinach leaves -- a problem especially in organic cultivation. Growers have safety measures to ensure spinach is attractive, tasty and safe, but pathogens keep coming up with new ways to get around them, said Allen Van Deynze, associate director of the UC Davis Plant Breeding Center, directed by Charlie Brummer.
To see if livestock grazing is beneficial in organic farming, or poses food safety risks, multistate research partners received a nearly $1 million grant from the USDA to study the impacts of livestock grazing cover crops on the bacterial population dynamics, soil building, and environmental health. Professor Amelie Gaudin, Plant Sciences, is part of the research team.
The Department of Plant Sciences has released six new varieties of organic dry beans which are higher yielding, and are resistant to bean common mosaic virus (BCMV), a disease that prevents bean plants from maturing promptly and uniformly. Spearheading the project were Ph.D. candidate Travis Parker, Distinguished Professor Paul Gepts, and Charlie Brummer, professor and director of the Plant Breeding Center at UC Davis.
California organic farmers are sharing information about their efforts to combine reduced tillage with the use of cover crops on their vegetable farms to protect and improve soil health while adding carbon and diversity to their production systems. Jeff Mitchell, Plant Sciences, UC Davis, is spearheading this ongoing project.
