First Rafael Munhoz Pedroso—a graduate student in Dr. Albert Fischer's lab—was awarded first place at the California Weed Science Society's (CWSS) annual meeting for his student oral research presentation on Uncovering the Mechanism of Resistance to Propanil in Ricefield Bulrush (Schoenoplectus mucronatus (L.) Palla) from Rice Fields of California.
Then three days later, he wins first place in his section at the Southern Weed Science Society (SWSS) meeting in Savannah, Georgia for this research talk on Target-site Resistance to Propanil in Cyperus difformis L.: Implications for Management in Rice Fields of...

This is the second year that Rafael Munhoz Pedroso—a graduate student in Dr. Albert Fischer's lab—was awarded first place by the California Weed Science Society (CWSS) for his student oral research presentation. This year his research work was on Uncovering the Mechanism of Resistance to Propanil in Ricefield Bulrush (Schoenoplectus mucronatus (L.) Palla) from Rice Fields of California.
Graduate students Marcelo Moretti—Dr. Brad Hanson's lab—and Whitney Brim-DeForest—also from the Fischer lab—received first and second place (respectively) for their student research posters....

New Organic Herbicide Registration for California
Richard Smith, Farm Advisor
University of California Cooperative Extension, Monterey County
A new organic herbicide, Suppress, from Westbridge Company is now in the 30-day waiting period with the California Department of Pesticide Registration and should be fully registered by mid-February of 2015. The active ingredients are Caprylic and Capric Acids and were approved by the Organic Materials Review Institute (OMRI). It is a contact burn-down material that is registered for use in and around food crops including vegetables, trees and vines. I...

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...
