CONTROL OF BOLLWORM /TOBACCO BUDWORM COMPLEX IN ARKANSAS COTTON IN 2002

摘要

Two studies were conducted to determine the efficacy of new chemistries and experimental compounds on bollworm/tobaccobudworm complex. Populations in both studies were 85% tobacco budworm and 15% cotton bollworm. The synthetic pyrethroidsand carbamates in the studies did not perform well. Spinosad (Tracer) alone or in combination with other productsgave the highest levels of control in both studies. Emamectin benzoate (Demin) also did well after 2 applications. Yieldswere again highest in the spinosad treatments.
