Abstract

Blackbird damage to ripening sunflower is forcing some growers to plant alternative, albeit less profitable, crops. Currently, only Bird Shield® (a.i., methyl anthranilate) is registered as a bird repellent on ripening sunflower. However, field experiments with Bird Shield showed no consistent differences in damage levels between treated and untreated plots. During September and October 2003, we screened five insecticide formulations for feeding repellency using individually caged red-winged blackbirds. The tested insecticides are registered and currently available for use on ripening sunflower. They were Asana® XL, Baythroid® 2, Lorsban®-4E, Scout X-Tra®, and Warrior® T.
