RESPONSE OF TWOSPOTTED SPIDER MITE POPULATIONS TO PROGRAMS OF ABAMECTIN, BIFENAZATE, HEXYTHIAZOX, SPIROMESIFEN, AND AN ESSENTIAL OIL OF CHENOPODIUM AMBROSIOIDES MITICIDES IN FLORIDA STRAWBERRY CROPS

Programs of twospotted spider mite (Tetranychus urticae) management in strawberry were evaluated in two field experiments during 2007 that measured effectiveness of various miticides, a non-ionic surfactant, and their frequency of application. Miticides evaluated included two formulations of abamectin and single formulations of bifenazate, hexythiazox, spiromesifen, and essential oil of Chenopodium ambrosioides. All of the miticides provided significant reductions in spider mites. Three weeks after initial application of treatments the most effective reductions occurred when abamectin, bifenazate, hexythiazox, spiromesifen were used.
