Gowan Company, plus partners SDS Biotech and Nissan, announce that the rice herbicide benzobicyclon, and the end use product Butte, have received Section 3 registrations from the U.S. Environmental Protection Agency and the California Department of Pesticide Regulation.
Butte is a granular herbicide which combines the HPPD inhibitor benzobicyclon with the ALS inhibitor halosulfuron widely used in rice.
Butte herbicide controls a wide range of broadleaf, grass, and sedge weeds. It’s intended as an early-season treatment in an integrated rice weed control program.
With herbicide resistance rapidly developing in key rice weeds, Butte offers growers a new mode of action to control weeds which may have developed resistance to older chemistries.
According to the Gowan Company press release, Butte's new mode of action in rice, combined with good crop safety and weed control, makes it a good tool for California rice producers.
Butte will be available to growers in limited quantities in Spring 2017.
