ABSTRACT

VipCot genotypes Cot 102, Cot 202, and Cot 203 were evaluated for activity against bollworm in a field test subjected to very high larval numbers. VipCot genotypes provided good to excellent control of bollworm and provided significant increases in seedcotton yields over that of the conventional genotype, Coker 312. Cot 202 and Cot 203 gave the highest levels of bollworm control, and their yields were unaffected by bollworm.
