Another link to a University of California Cooperative Extension (UCCE) Field Day.
Weed Science Farm Advisor John Roncoroni (Napa and surrounding counties) will be show and discuss the results of a wine grape herbicide trial at Hess Vineyards near American Canyon CA on July 17th.
Should be an interesting opportunity to talk about new herbicides, changing weed problems, and resistance management in wine grape production systems and other perennial crops.
Hope to see you there.

See attached flyer for a University of California Cooperative Extension (UCCE) Field Day at the West Side Research and Extension Center near Five Points, CA.
Six UC Farm Advisors and Specialists will discuss current research on virus, fungal, and insect pests of vegetable crops as well as conservation tillage and cropping system issues during the 8-11am program.
From a weed science perspective, two speakers, Kurt Hembree (Fresno Co) and Scott Stoddard (Merced/Madera Co) will discuss weed control research in drip-irrigated tomato.
Take care,
Brad

It’s that time of year again when hot weather fuels the creation of ozone, or smog. Some herbicides emit volatile organic compounds (VOCs) that contribute to ozone formation. Using herbicides that release VOCs may be restricted in certain California locations between May 1 and October 31.
If you plan to apply a herbicide, use the Department of Pesticide Regulation’s VOC calculators to determine emissions from fumigant and nonfumigant pesticides. Get there by clicking on the Air Quality button at the top of each herbicide treatment table in the UC IPM Pest Management...

Threespike goosegrass is a warm season perennial grass which is a problem weed in some almond orchards around Orland, California. It is easily identified by its distinctive (see photo) seed heads (spikes). It is usually a problem during the first years of an orchard. The bunch grass growth habit traps nuts at harvest. After somewhere between 5-8 years, it is too shaded to continue being a problem weed.
Pre-emergence control of threespike goosegrass is the best approach. Since goosegrass can emerge from April through August, a long persisting pre-emergence herbicide is needed. Alion is a new herbicide with more persistent weed control, which we are currently testing for April through August threespike goosegrass control. Alion...

UC Cooperative Extension agronomy advisor Doug Munier retires after 34 years
Doug Munier, UC Cooperative Extension advisor in agronomy, retires in June following a 34-year career split equally between the Northern California offices serving Glenn, Butte and Tehama counties and the southern San Joaquin Valley's Kern County.
Munier always enjoyed working outdoors - both the working and the outdoors, he said. He developed an interest in agriculture as a high school student employed part-time and during the summer on a dryland barley and cattle farm near Banning,...
