Collaboration Results in Win-Win Endangered Fish/Safe Thiobencarb Use Policy
By Laurie Greene, CalAgToday Editor and Reporter
Roberta Firoved, Industry Affairs Manager for the California Rice Commission, stated in a press release Wednesday, “A great example of our positive relationship with the U.S. Environmental Protection Agency (U.S. EPA) is found in the recent press release, ‘U.S. EPA, federal and state agencies, rice growers, industry act to protect endangered salmon and steelhead trout in California.’”
In the release, Jared Blumenfeld, EPA’s Regional Administrator for the Pacific Southwest, states, “Working closely with our state and federal partners, our joint efforts will protect salmon and steelhead trout while maintaining rice production in California. This action also supports EPA’s commitment to minimize pesticide pollution in the San Francisco Bay Delta.”
“This is a smart approach to pesticide use that includes important safeguards for protected fish while still allowing growers to care for their crops,” said Will Stelle, administrator of National Oceanic and Atmospheric Administration (NOAA Fisheries) West Coast Region, in the same release. “This demonstrates that we can find balanced and workable solutions through collaboration.”
The California Department of Pesticide Regulation (CDPR) established measures to protect salmon and steelhead trout based on proximity to endangered and threatened species habitat according to NOAA Fisheries geographic locations, as well as information and best management practices from the California Rice Commission and its grower members, plus the California Regional Water Quality Control Board – Central Valley Region. U.S. EPA and Valent, the manufacturer of the herbicide thiobencarb, also worked to put these restrictions in place.
After reviewing CDPR’s data on pesticide use and the state’s protective measures to be enforced by County Agriculture Commissioners, NOAA Fisheries found that thiobencarb use on rice in California would not jeopardize salmon and steelhead trout provided protective measures currently being applied in California are ensured.
“The positive approach we applied throughout development of the thiobencarb use conditions,” Firoved explained, “expanded into our interaction with the NOAA National Marine Fisheries Services (NMFS) as they researched and wrote the biological opinion (BiOp) for thiobencarb.”
Thiobencarb is a systemic, pre-emergence herbicide in liquid or a granular formulation that inhibits shoots of emerging weed seedlings. First registered for use on rice in 1982, thiobencarb is used to control grasses, sedge and broadleaf weeds in food crops such s rice (represents 95% of use), lettuce, celery, and endive. Thiobencarb, or Valent’s Bolero® UltraMax Herbicide, may be applied using ground spray equipment or by aircraft.
“The win for rice growers is that the farming practices developed over time are also protective of endangered species. We always assumed this to be the case, and entrusted the thiobencarb BiOp for confirmation.
Reflecting on the successful collaboration, Firoved stated, “We have no magic bullet, nor do we approach the issues with contention. Our perspective is that all participants around the table are looking for the same end result, no matter where they work.”
