Damage to ripening sunflowers by blackbirds is an important agricultural problem in the northern Great Plains. In an effort to reduce crop loss by non-lethal means, several insecticidal formulations were evaluated for potential bird repellency. One formulation, Lorsban-4E, was highly effective in feeding studies with caged blackbirds. Chlorpyrifos (an organophosphate pesticide) is a registered insecticide and acaricide commonly used to control insects on sunflower, and is the active ingredient… CONTINUE READING
