Compounds produced by sorghum plants to defend against insect feeding could be isolated, synthesized and used as a targeted, nontoxic insect deterrent, according to researchers who studied plant-insect interactions that included field, greenhouse and laboratory components. The researchers examined the role of sorghum chemicals called flavonoids —specifically 3-deoxyflavonoid and 3-deoxyanthocyanidins — in providing resistance against the corn leaf aphid, a …

California Department of Food and Agriculture (CDFA) Center for Analytical Chemistry (CAC) scientists Bahar Nakhjavan, Nighat Sami Ahmed, and Maryam Khosravifard were recently published in an academic journal after developing an improved method to test for mycotoxin in feed. Their article, “Development of an Improved Method of Sample Extraction and Quantitation of Multi-Mycotoxin in Feed by LC-MS/MS,” details their research …

The threat that climate change poses to our world, our ecosystem and our health demands bold policy solutions, and, as the devastating impacts of a warming Earth mount, the push for the development of robust and comprehensive federal climate policy is gaining traction.

Currently, we are experiencing a prolonged heatwave on the central coast.  Heatwaves have become a recurring phenomenon in recent years, especially in late summer. With thousands of acres of cool season vegetables in the ground, irrigation will be critical for keeping crops cool and for supplying enough moisture to meet their water needs. Crops can be kept cool by maximizing evapotranspiration (ET).  …

Scientists are closer to gaining the upper hand on a disease that has wiped out citrus orchards across the globe. New models of the bacterium linked to the disease reveal control methods that were previously unavailable. Metabolic models of organisms are like road maps of cities. “They show you all the biological processes, and how they work together,” said UC …

In September 2019, huanglongbing—also known as HLB or citrus greening—was detected in residential citrus trees located in Ventura County, in southern California (and just recently, the first HLB carrying Asian Citrus Psyllid was detected in a commercial CA citrus grove). The disease, which has no known cure, is caused by a bacterium that devastates citrus plants and is transmitted by …

California dairy methane reduction programs are providing a valuable mitigation strategy in the state’s efforts to fight climate change. A growing body of evidence shows that the Dairy Digester Research and Development Program (DDRDP) and Alternative Manure Management Program (AMMP)have proven to be among the state’s most cost-effective approaches for reducing greenhouse gas emissions. The California Department of Food and …

To address nitrate pollution of groundwater, the Central Valley Regional Water Quality Control Board has initiated a regulatory program requiring growers to utilize nitrogen management practices that mitigate nitrate loading. Because nitrogen plays such a critical role in in the growth and development of avocado trees — and because it can be difficult to ensure trees are receiving the optimal amount …
