Abstract:Five cotton genotypes were evaluated over a 2-year period to determine effects of thrips injury on leaf development and yield under 2 different control methods and in untreated plots. Genotypes with pubescent leaves exhibited a high degree of resistance to thrips injury as measured by leaf area development, and yields were not significantly different regardless of treatment. Untreated glabrous types showed a significant reduction in leaf area development. However, when treated with a systemic insecticide at planting, glabrous types exhibited increased leaf area and greater yields. Foliar insecticide treatments made after thrips injury appeared did result in some improvement in leaf area development but did not result in increased yields in the glabrous genotypes.
