BioWorks’ BotaniGard ES, a biopesticide in combination with Bifenthrin, has received a FIFRA 2(ee) recommendation from the New York State DEC for the control of annual bluegrass weevil adults in golf course turfgrass.
Independent university trials have shown how BotaniGard ES and Bifenthrin act in a synergistic fashion to suppress annual bluegrass weevil populations on golf course fairways. On pyrethroid-resistant populations, efficacy from either product is low to none when applied alone against adults. Applied together, however, efficacy jumps to greater than 70 percent.
Adding BotaniGard ES to a pyrethroid application is a viable new approach for limiting resistance development:
--In populations that are still pyrethroid susceptible, the combination will delay or eliminate resistance development.
--In populations that are already pyrethroid resistant, the combination allows for the continued use of pyrethroids for adult control.
“ABW damage ranks high with superintendents,” said Joe Gionta, director of marketing and sales. “We are pleased New York golf courses now have the ability to use BotaniGard and Bifenthrin to control the top insect pest in the northeastern United States.”
