UC Weed Science (weed control, management, ecology, and minutia)

We talk about herbicide resistance all of the time in California rice, but how does it evolve in a field? Understanding how herbicide management selects for resistant populations is an important part of preventing the problem from occurring in your fields.

The giant invasive grass arundo (Arundo donax), one of the weeds targeted under the USDA-ARS-funded Delta Region Areawide Aquatic Weed Project (DRAAWP), has been re-acquainted with one of its natural enemies imported from arundo's native range.

Annual bluegrass is a common winter growing grass in agricultural and urban environments. It is a well-known weed of turfgrass systems but its ability to grow in a range of environments makes it an increasing problem for other agricultural systems.

A quick note to share a link to our (semi) regularly updated "Herbicide Registration on California Tree and Vine Crops". Click here for a link to the PDF version on the Weed Research and Information Center page (this is probably your best bet for the most up-to-date version).

A position announcement I shared in October (http://ucanr.edu/blogs/blogcore/postdetail.cfm?postnum=22336) was re-released last week. The new search ends on April 18, 2017. Job announcement for the Associate Director / Field Research Coordinator for the Western Region IR-4 Program.
