UC Weed Science (weed control, management, ecology, and minutia)

I've made a couple posts about herbicide resistant weeds but I thought today would be a good time to go back to the basics for a moment. Occasionally, there is some confusion about the definitions of a "resistant" weed versus a "tolerant" weed.

Happy New Year! Today I thought I'd attach a poster presentation from the recent 38th Annual Almond Industry Conference.

This is one part follow up to my previous post on glyphosate resistance and one part test of a tool to imbed articles in the blog. The above frame has a 2008 report that Anil Shrestha, Kurt Hembree, and I wrote for California Agriculture on our glyphosate-resistant hairy fleabane work.

I thought I'd followup on my post last week about herbicide resistant weeds with a little more detail on our recent (and ongoing) work on glyphosate-resistant horseweed (Conyza canadensis) which is also known as mare's tail.

This is a reposting of an article I recently wrote for the California Weed Science Society Journal (also reprinted by Western Farm Press). The article is based on a presentation I made at the California Weed Science Society annual meeting in Visalia last January.
