Today, I thought I'd share a set of photos from a herbicide symptomology demonstration that I conducted in fall 2013 for our UC Weed Science School (next scheduled for fall 2015) and more recently in spring 2014 for a training session with other UC Cooperative Extension personnel.
For those of you that work regularly with herbicides of different modes of action this may be old-hat. However, many of us who get questions about herbicide injury in the field don't get always get to see comparisons under controlled conditions.
A few definitions, caveats, and brief explanations of the attached slides:

This post is a quick reminder that this is the last week for public comment on 123 proposed UC Cooperative Extension positions (closes July 21st).
The proposed positions are listed at this website and you can read the 2-page proposal and see any comments by clicking on the position title.
The UC ANR leadership team stresses that "the value of the comments is not in the quantity but the quality. These comments are not being used as votes. One collective set of thoughtful comments from an organization/ group that explain why the position is important based on filling a critical need means more than an overwhelming number of...

Yesterday was the 58th Annual Weed Day hosted by the UC Davis Weed Science Program and the UC Weed Research and Information Center.

I think we had a really good program this year made up of a half-day field tour in the morning followed by lunch and an afternoon program of research presentations. We also had one of the highest number of participants (about 160 total) that we've had in a while. We've maxed out our registration for the past five or so years so this remains a popular...

With summer kicking in, I thought it would be a good time to revisit organic herbicides. That's because most of these contact postemergent herbicides work better at higher temperatures than cooler temperatures. So to get the best bang for your buck and the accompanying satisfaction of seeing weeds practically die in front of your eyes (see photos below), summertime is optimal for using these herbicides.
Examples of organically labeled herbicides are listed below. There were a lot more a few years ago and some may still be registered such as GreenMatch and Matran but I cannot find them on the current product lists of the company that registered them.
Work by Tom Lanini and others has also shown...

At a meeting yesterday, Joe DiTomaso mentioned a new book: The Weed Agency written by Jim Geraghty.
I wonder if it's anything like Curse of the Giant Hogweed (Peter Shandy Mysteries) by /span>
