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...

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...

Before I go out the door for the Thanksgiving holiday weekend, I wanted to share a link to the recent Western IPM Center newsletter, The Western Front. 

The October 2012 edition had a really nice writeup about the glyphosate-resistant weed workshops and IPM publications that I mentioned in my October 29 post.  The author did a great job summarizing the issues, objectives, and even the IPM publications so I'll encourage you to take a look for yourself.

Last winter, I particpated in a series of seven half-day workshops in California, Oregon, and Washington on herbicide-resistant weeds.  These workshops were organized by Kassim Al-Khatib from the Univeristy of California Integrated Pest Management (IPM) Program and had a special focus on glyphosate-resistant weeds in tree and vine crops.

In preparation for these workshops, we wrote a series of extension publications that I wanted to share today.  The publications and resulting presentations were prepared by weed scientists from various Universities, Cooperative Extension, and USDA-ARS and included various aspects of herbicide resistance in permanent crops.  Even as somone who thinks about herbicide resistance...
