We recently updated the Herbicide Registration chart for California tree and vine crops. Since I've done this two years in a row, I think this is officially a trend and can be called an "annual update"!
The updated version of the T&V herbicide chart is attached at the bottom of this post and is also available at this link: http://wric.ucdavis.edu/PDFs/herbicide_registration_on_horticultural_tree_and_vine_%20crops_2011_10.pdf to the

Today I thought I'd put in a plug for the California Weed Science Society (CWSS) annual meeting to be held January 23-25, 2012 in Santa Barbara. Information on the meeting can be found in the October newsletter at: http://www.cwss.org/PDF/CWSS_Fall_2011_Newsletter.pdf and links to the Program and Registration can be found at: http://www.cwss.org/. The main CWSS page also has information on a new Photo Contest, the Student Paper and Poster Contest, the Student Scholarship Program, and Awards and Honors presented to students and members last year.
Also, I've attached a link to the

... well, a new name and new uses for a familiar product anyway.
I received a notification today that Dow AgroSciences received California registration for TrellisTM herbicide for use in grapes and tree nuts.
The active ingredient in Trellis, isoxaben, may be familiar to folks who have used Gallery T&V herbicide which was registered in 1998. This is a residual herbicide that will provide several months of control for a fairly broad range of broadleaf weeds (minor activity on some grasses). For more info, go to the UC Weed RIC "herbicide susceptibility chart" and scroll down to isoxaben (Gallery) in the herbicide window or read the Trellis label...

Organic Herbicides - Do They Work?
In recent years, several organic herbicide products have appeared on the market. These include Weed Pharm (20% acetic acid), C-Cide (5% citric acid), GreenMatch (55% d-limonene), Matratec (50%...

Today I'm asking for input from folks who work in orchard and vineyard weed control (land owners, managers, pest control advisors, sprayer operators, etc.) on your take on herbicide resistant weeds. What have your experiences been and what are your concerns?
Below is a link to an online survey to find out what tree and vine weed managers think about herbicide resistance. Your responses will be kept anonymous but the overall trends will be helpful for planning research and extension programs. Eventually, the results of this survey will be coupled with the results greenhouse testing of weeds collected throughout the state.
