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...

Over the past several years, land managers and ranchers in Marin and Sonoma counties have been concerned with the spread of woolly distaff thistle (Carthamus lanatus). However, there is very little research conducted on the control of this species. Because of the lack of direct information on its management, land managers have relied on information previously published on yellow starthistle (Centaurea solstitialis). Yellow starthistle is a related species with some phenological similarities to woolly distaff thistle, but it does not provide a perfect analogy.
As a result, we tested a number of herbicides for the control of distaff thistle at two timings (mid-winter and spring) and two rates in Marin County. Our...

The California Weed Science Society recently published the 4th edition of the Principles of Weed Control as an e-book. This textbook/handbook that has been a valuable resource for many years and I'm excited that it has been updated. Additionally, by electing to publish it as an e-book (Kindle edition is available at Amazon.com), the price has been dramatically reduced so, hopefully, more students and...
