Newsletter content includes:
- Vertebrate damage
- Chemical thinning of olives
- Tips on producing the earliest early citrus in the San Joaquin Valley Herbicide registration chart
- Resource and market information for enterprise selection.

The Asian citrus psyllid (ACP) continues to be found in several California counties. New finds are being made on a weekly basis. Ventura County and others with this pest remain in quarantine, which means fruit and plant material movement is restricted in these counties.
UC’s Elizabeth Grafton-Cardwell has recently provided an update on LA’s urban infestation. The update can be found on UC ANR’s Citrus Bugs Blog.
UC researchers have begun releasing Tamarixia radiate in Riverside County and soon into Los Angeles county. Tamarixia radiate is a tiny wasp and a natural enemy of ACP. Details of the release and the program can be found on the ANR News Blog.
Invasive species cause billions of dollars’ worth of damage annually. As with all invasive species, it is primarily people who are responsible for ACP’s movement. Please do what you can to avoid moving these pests.

California agricultural producers and consumers rely on wild bee species to pollinate crops. Wild bees pollinate more than one third of California’s pollinator-dependent crops. These crops are currently estimated to be worth $11.7 billion annually. Many of these bees live in neighboring livestock rangelands, and provide diversification vital to sustaining our food supply.
Researchers have found that in addition to the economic benefits of pollination, animal pollinators provide up to 40 percent of some essential vitamins, minerals, and dietary lipids provided by fruits and vegetables.
Please see UC Berkeley’s Native Bee Habitats Key to Farming, Conservation, Nutrition for details.
Preserving and expanding pollinator habitats throughout our communities will is beneficial for all. The Pollinator Partnership is an incredible resource to help us accomplish this important goal.
