University of California, Riverside--Cooperative Extension Weed Science Specialist
The Department of Botany and Plant Sciences invites applications for an Assistant Cooperative Extension Weed Specialist (11-month tenure-track, 90% CE, 10% OR). The Weed Specialist will work with Farm Advisors, other Extension Specialists, faculty, land managers and the industry to conduct research on biology of weedy and invasive plants and their interactions with managed ecosystems, focusing on urban systems. Research could address potential invasiveness of ornamental or biofuel crops; environmental issues associated with herbicide use and other weed control practices; development of integrated weed management practices in...

The Weed Science Society of America (WSSA) recently published a press releasee on suggested best management practices for reducing the potential for biofuel crops to become invasive weeds. Jacob Barney from Virginia Tech (and a former UC Weed Science researcher) is highlighted in the press release. I've pasted the text below (in black) or you can click HERE for the direct link. The pdf is also attached at the bottom of this post.

2010-2011 Roadside Weed Control Evaluation with Organic and Conventional Herbicides
Richard Smith and Steve Tjosvold, Farm Advisors
University of California Cooperative Extension, Monterey and Santa Cruz Counties
A trial was established near Bonny Doon, California (in the Santa Cruz mountains). The objective of the trial was to screen alternative roadside herbicides in the wake of the ban on the use of glyphosate for roadside weed control imposed by the Santa Cruz County board of supervisors in 2005. The plots were in an area that had large population of French broom. Other weeds present...

Some data from over 15 years ago may help people better asses the damage from phenoxy herbicide drift in the San Joaquin Valley this year. This data is only for one trial in one year, but shows the range of damage which can occur in cotton. The yield losses were the greatest when the cotton plants show continued phenoxy symptoms on new growth all season long.
Thousands of acres of cotton in the Sacramento Valley were damaged by phenoxy herbicide drift in 1995. Cotton had not been planted on a large acreage in the Sacramento Valley since being planted in the 1920’s. This widespread damage continued in 1996 and 1997 and only stopped when the phenoxy herbicde manufactures severely restricted...
