California's severe drought is entering a fourth year. With that, scientists met with ranchers to give background and gain feedback on a key climate indicator: the U.S. Drought Monitor.
The November 7 workshop held at the University of California, Davis, and webcast to 15 satellite locations across the state posed questions to a panel of experts who help publish the weekly analysis. UC Davis researchers also discussed new findings from in-depth rancher interviews along with strategies for maintaining the nutrition of cattle during the water shortage.

Two Asian citrus pysllids (ACP) were found in a trap near Exeter in November, just 10 miles away from the UC Lindcove Research and Extension Center. That brings to 29 the number of locations in the central San Joaquin Valley, from Bakersfield to Dinuba, where Asian citrus psyllids have been trapped.
Perhaps still more unsettling is the fact that reproducing populations of ACP have been found in urban areas in Tulare County, confirming that the pest is established in a county where farmers produce citrus valued at more than $1 billion annually.
“The psyllid is here, it's established, but still at low levels,” said Beth...
In order to slow global climate change and achieve greater energy independence, Americans are showing an increasing interest in switching over to clean, renewable fuels made from home-grown crops. In fact, Congress has mandated that at least 16 billion gallons of cellulosic ethanol be added to the U.S. fuel supply by 2022.
However, estimates suggest that growing crops to produce that much biofuel would require 40 to 50 million acres of land, an area roughly equivalent in size to the entire state of Nebraska.
“If we convert cropland that now produces food into fuel production, what will that do to our food supply?” asks Maggi Kelly, UC Cooperative Extension...

When you think of “amber waves of grain,” do you think of wheat?
You should. It's not only part of “America, the Beautiful,” (lyrics penned in 1893 by Wellesley College professor Katharine Lee Bates), but it's part of California's agricultural landscape.
California annually grows about 800,000 acres of wheat, with about half used for human consumption and the rest for animal feed. It's a highly sustainable rotational crop.
Wheat growers seed the crop in the fall and winter, and harvest it in late spring or early summer. That's when we see the “amber waves of grain.” In the winter, weather conditions permitting, it's emerald green.
Since this cereal crop relies heavily on...
The insecticide chlorpyrifos is a critically important tool for California producers of alfalfa, almonds, citrus and cotton, according to a comprehensive report coordinated by the UC Statewide Integrated Pest Management Program. As part of an action plan, the report identifies specific research, extension and policy gaps that should be addressed to ensure safe, effective use of the insecticide.
The report, Identifying and Managing Critical Uses of Chlorpyrifos in Alfalfa, Almonds, Citrus and Cotton, was commissioned by the California Department of Pesticide Regulation (CDPR) earlier this year and...
