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...

Hike off-trail through most any part of the Sierra Nevada and you may find yourself losing your hat to a low hanging branch, your shoe to a thicket of dead and dying brush, or your companion to the crevice hidden by the wall of young trees.
There is no doubt that the forests of the Sierra Nevada, while amazingly beautiful, have grown dense with vegetation. Consequently, forests have become increasingly susceptible to high severity fires, which negatively impact the forest's overall health and our ability to enjoy it.
There is a relationship between a healthy forest and its density. The denser the forest, the more competition individual trees have for valuable resources, such as water, light and nutrients. The effects of...

Beginning in November, a free, drought-focused soil nutrient management series for farmers will be hosted online by the University of California Sustainable Agriculture Research & Education Program (UC SAREP), FarmsReach and Sustainable Conservation.
“Farmers and ranchers have to continually adapt their management of soil nutrients to changing conditions,” said Aubrey White, UC SAREP's communication coordinator. “Adaptation during this extreme drought presents a new challenge for growers and researchers alike. This forum dedicated to the issues farmers will face next season is an opportunity to share resources, research and...

Under sunny skies, a cool breeze blowing off the ocean at Asilomar State Beach, California Naturalist Scott Van Tyle pulls out a knife and begins dissecting a seaweed root ball that had washed up on the sand. A group of fellow naturalists quickly gather around to see what tiny sea creatures call the massive tangle home.
Similar scenes were repeated frequently during the three-day California Naturalist conference in October. The legless lizards and gopher snake brought in by a Fort Ord Dunes State Park ranger, a family of raccoons under the dining hall deck, deer browsing among the cottages and a beautiful sunset drew quick attention from participants. It is this enthusiasm that defines California Naturalists, a community with...

Nursery workers are the first line of defense in detecting light brown apple moth when growing ornamental plants in commercial nurseries. A new brochure and video can help those in the field distinguish light brown apple moth from several look-alike caterpillars.
Light brown apple moth is currently under a California Department of Food and Agriculture quarantine that regulates the interstate shipment of plants to keep the moth from spreading to new areas. It has been quarantined in various counties throughout coastal California...
