The $1 million UC Cooperative Extension Presidential Chair for California Grown Rice has been awarded to Whitney Brim-DeForest, UCCE rice advisor for Sutter, Yuba, Placer, Sacramento and Butte counties.
Brim-DeForest said she will use the funds generated from the endowed chair to hire a full-time technician to monitor a research study at UC Davis on weedy rice. Weedy rice is the same species as cultivated rice and it produces rice, however the grain falls off the plant before harvest.

Over the past year and a half, I have been conducting research and extension with weedy (red) rice (Oryza sativa L.), which has re-emerged as a pest in California rice fields. What makes this plant so interesting is that it is the exact same species as cultivated rice (also Oryza sativa L.). This means that it is edible (fit for human consumption), not subject to quarantine (not regulated at the state or federal level), and difficult to distinguish from cultivated rice in the field, since it looks a lot like the cultivated rice varieties. It is, however, considered a pest, due to its impact on yield and processing quality.
Because it is rice, and it is edible, my colleagues and I have had to do a lot of...

The 2017 season kicked off with much fanfare regarding weedy rice. Thanks to the vigilance of the entire rice industry, the UCCE Rice Advisors received many calls regarding weedy rice, starting in late June, as growers finished their herbicide applications. Calls continued to come in through July and August. The California Crop Improvement Association (CCIA) began inspecting fields as the rice headed, and suspected plants were pulled and sent to the UCCE Weedy Rice Team for genetic testing.
By the end of the season, we had a total of:

Over the past year, weedy rice has become a top issue in California rice, both for individual growers and for the industry as a whole. Working together, the University of California Cooperative Extension and the California Rice Commission have come up with a set of tools to assist in getting control of this pest. Of course, none of it would be possible without the input and cooperation of the Pest Control Advisers (PCAs) and California rice growers, who are the first line of defense in dealing with weedy rice. Additional assistance in material development and funding have come from the California Rice Research Board, the California Crop Improvement Association and the staff at the California Rice Experiment...
