This is the abstract and a poster from a presentation that I made at the 2016 Weed Science Society of America meeting in San Juan, PR. The results were generated from one run of each of the experiments. At this time, all of the studies have been replicated, the data is being analyzed and the manuscripts are in preparation.

In addition to the well-known rice weeds we deal with every year, there are a couple of weeds I want to bring to your attention this year. One is an invasive and the other has been with us for a while.
The winged primrose willow was identified in 2011 in several rice fields near Richvale in Butte County. Since then it has spread to several other fields, up to 3.5 miles south of Richvale. Winged primrose willow was recently given an “A” pest rating by CDFA. What this...

There is already a wall on our southern border, apparently, made of arundo (giant cane). This NY Times feature discusses US - Mexico cooperation in tackling the giant grass. Great pictures, too.
Arundo is also a big deal in California. Locally, it is one of the target species in the Delta Regional Areawide Aquatic Weed Project.

The University of California Sierra Foothill Research and Extension Center will host a half-day workshop on June 28th, 2016 focused on practical approaches to managing medusahead and barb goatgrass on rangeland. UC researchers and cooperators have made steady headway over the past several years refining how basic tools like herbicide and grazing can be applied to manage these invasive plants. This workshop will explore some these advances and also look at the economic costs and benefits of controlling theses weeds for livestock production as well as how to develop a whole-ranch management plan for these and other weeds. Substantial time will be allocated to see treatment plots in the field as well as hear...

Solano Irrigation District (SID) delivers water to 37,000 acres of farmland through an extensive network oflined canals, pipelines, and unlined irrigation and drainage canals. The unlined canals are typically drained at the end of the water delivery season in October and remain dry until spring. During dewatering, winter annual weeds can germinate in the unlined canals and grow until the canals are refilled with water. During the irrigation season, the weedy leftovers clog up control gates, meters, and irrigation equipment. To minimize flow reductions and equipment interference, SID must manage winter weeds through mechanical removal or herbicide application.
Mechanical weed removal is expensive and requires specialized...
