Following up on my post last week about T&V herbicide changes, today I want to focus on hot-off-the-presses information about Alion (active ingredient = indaziflam) manufactured by Bayer CropScience.
Alion herbicide, which was labeled in California tree nuts, citrus, stone fruit and pome fruit was just received a supplemental label for use in grapes. For grapes there is not a range of use rates like in orchards - only 5 fl oz of product per acre (0.065 lb ai/A) is registered and only one application per 12...

Over the past few years, herbicides with the active ingredient glufosinate (Rely, Rely 200, Rely 280) have become very important in California tree nut orchards and grape vineyards.
Glufosinate is classified as a "Group 10, or Group B" herbicide an inhibits an enzyme important in the production of the amino acids glutamine in plants. Although it sounds similar to another amino acid inhibitor, glyhosate (the active in Roundup and others) glufosinate works quite differently than the Group 9 herbicide glyphosate.

It's that time of the year when I try to update the list of herbicides registered for use in California orchard and vineyard crops. The attached version has all the updates that I have been made aware of by my industry reps during the year. However, I have not done my end-of-year-herbicide-label-reading-marathon yet so it may change slightly over the next few weeks once I do that. Over the next few weeks, I'll try to discuss some of the more important changes in the T&V herbicide landscape.
Today, I'll focus on what could be important news for vineyard weed managers, registration of a new active ingredient for grape vineyards. Flazasulfuron (trade name: Mission...

Ok, I'll admit that I fully intended to do something useful today but got distracted thinking about weed control research, weed science extension, and herbicide-resistant weeds (what do YOU think about on Saturday afternoon?).
Anyway, while procrastinating today, I ran across the blog of one of my weed science colleages at the University of Wyoming, Dr. Andrew Kniss. In an October post, Dr. Kniss discussed the question "Do genetically engineered crops really increase herbicide use?" that largely discussed the data in a report on the impact of GMO crops on...

I received a press release this week from the Weed Science Society of America (WSSA) that I thought would be of interest to followers of the UC Weed Science blog (link above, or attached below).
The press release lays out a dozen examples of "unfortunate (and illegal) consequences that can happen when you don't" follow the information on a pesticide label. I thought the first reason (wrong product,...
