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...

Weed resistance issues are nothing new for university researchers and the farmers they advise.
Nevertheless, science continues to partner with agriculture to find ways to address the challenges of herbicide resistance in crops like tomatoes, melons, and a host of other agricultural applications.
The popular Weed Day at the University of California stands as a shining example of such concern. For at least the last five years. The...

From the Invasive Plants in Southern California blog :: Nov. 22, 2013
Hi All. In my last blog the subject was about what I had learned regarding the use herbicides as a tool for effective passive restoration of CSS and native grassland habitats. As an Extension Advisor my job is to not only develop new information, but to also try to move it forward into practice.
In this case that means educating land managers and related professionals on how to efficiently and accurately apply herbicides to large areas. That's what the Cooperative Mule is all about, so sit back, I hope...
