Comparison of Insecticides for Control of Fleahoppers on Texas Coastal Bend Cotton

Roy D. Parker


Provado (2 rates), Provado + Baythroid, Provado + Guthion, Bidrin, Orthene and Fulfil (Ciba CGA-215944, proposed common name pymetrozine) and an untreated check were compared for control of fleahoppers. Two applications were made at 6 day intervals. All insecticides significantly reduced fleahop-per numbers. Significant differences in aphid numbers were detected on only 1 of 4 inspection dates; Orthene treated cotton had more aphids than the other insecticide treatments. Fewer predators and parasites in various treatments generally reflected the presence of lower numbers of aphids in that cotton. Insecticide treated cotton produced an average of 200 lb/acre more lint than the untreated cotton.
