California rice growers will have a new herbicide available this year: Cliffhanger™, manufactured by Gowan Company. The active ingredient is benzobicyclon, which is the same as one of the two active ingredients in the currently registered herbicide, Butte®. Cliffhanger™ is a soluble liquid formulation (SC) which can be applied by ground-rig or airplane, including as a direct-stream application into the water. In contrast, Butte® is a granular formulation, as a pre-formulated mixture of benzobicyclon and halosulfuron. To use either product, applicators must attend a training and be certified.
Dates for the training are posted on the California Rice Commission calendar

Background
White water fire (Bergia capensis) was found in September of 2023, by the Butte County Agricultural Commissioner's office in a rice field in Butte County. The weed was identified by the California Department of Food and Agriculture (CDFA.) It is the first find of this weed in California, and possibly in the United States. It is native to Africa, southern China, and tropical Asia, and it is known to be in rice fields in Europe, Central and South America, as well as the Caribbean. It was likely transported in seed to rice-growing areas and has been established in those locations for many years.
In Butte County, the weed was only found in one rice field, and the Agricultural...

My name is Sarah Marsh, and I am excited to join UC Cooperative Extension as the new Rice Farming Systems Advisor serving Colusa and Yolo counties. I will be based out of Colusa at the Colusa UCCE office. I grew up on a diversified row-crop and orchard farm in Arbuckle and am grateful for the opportunity to serve the community in which I was raised. After completing my undergraduate degree in Plant and Environmental Soil Science at Texas A&M University, I obtained a M.S. in Horticulture and Agronomy at UC Davis, where I worked with Dr. Kassim Al-Khatib in studying weeds and herbicide resistance in rice agroecosystems. I have since worked in rice...
