I was debating about what to post on the weed blog this week and, like manna from heaven, a topic dropped in my lap!
Well ok, it was actually the summer newsletter from the Western Society of Weed Science but it had an article about biological control agents on houndstongue (Cynoglossum officiniale).
The article, entitled "Houndstongue Biological Control: Status Report" was written by Carol Randall from the USDA Forest Service. You can find the article at this LINK and scroll down to page 11 for Carol's summary...

In late 2016 and early 2017, the Weed Science Society of America (WSSA) organized a series of seven "Herbicide Resistance Listening Sessions" around the country.
Brian Schutte (from New Mexico State University) and I co-hosted the Southwestern session in Tulare, CA on February 15, 2017 and, if you're a regular reader, this may sound vaguely familiar since I tried to drum up interest on the blog in November 2016 and Pratap shared

A quick post today to share a link to the recently revised "UC IPM Pest Management Guidelines for Walnut" (UC ANR Publication #3471). You can download the whole document as a pdf here, or use it online at the above link
Lots of great sections on management of non-weed pests of walnut, but since this is the Weed Science blog, here's the direct link to Integrated Weed Management section authored this time by:
- J. A. Roncoroni, UC Cooperative Extension, Napa County

Several years ago, I had what seemed like a great weed research idea.
My idea addressed a serious agricultural weed problem in California, it was applicable to several cropping systems, it used an integrated approach to weed management, and it utilized a pretty novel approach (or so I thought). I proudly laid out this idea to my UC weed science colleague at a meeting, only to hear "That's great Brad but I think your predecessor tried that in the late 80's and it didn't work very well". After my damaged pride recovered a bit, I started thinking about the volume of research that we do that is not very easy to find out about after it is done.
As scientists, we often think about...

The journal California Agriculture recently published a special issue on research and extension efforts related to the University's Endemic and Invasive Pests and Diseases strategic initiative.
The subtitle of the special issue is: How UC and it's collaborators detect, contain, and manage (pests and diseases). There are six articles under three headings: Excluding Pests and Pathogens, Managing Newly Established Pests, and Maintaining Long-Term Management. Table of contents available HERE.
A group of weed scientists reviewed the California status of herbicide-resistant weeds...
