A new herbicide is available this year for use in California rice: RebelEX®, manufactured by Corteva. It is a premix of two other well-known herbicides: Clincher® and Granite SC®, both from Corteva. The active ingredients in RebelEX® are cyhalofop (same as Clincher®) and penoxsulam (same as Granite SC®). Since it contains cyhalofop, it is important to check with your respective counties on the buffer zones and aerial application restrictions for...

Weeds are important pests of California rice systems, and weed management can account for roughly 17 percent of total operating costs, according to a UC cost of production study./span>
For the past several years, California rice has been dealing with a pesky new weed, weedy rice aka “red” rice. Weedy rice is a difficult pest to manage, because it is the same species as rice (both are Oryza sativa L.), rendering herbicide use next-to-impossible. In the southern US rice-growing region (Texas, Louisiana, Mississippi, Missouri, Arkansas), they utilize two rice varieties (in rotation) that have been conventionally bred to tolerate the use of two herbicides: Clearfield (imazamox) and Provisia (quizalofop). Since weedy rice is susceptible to these chemicals, the entire field can be sprayed with these herbicides: the rice varieties survive, and the weedy rice is controlled. In California, these varieties...
