Abstract

Residual toxicities of registered and selected experimental pesticides used on citrus against Euseius mesembrinus (Dean) (Acari: Phytoseiidae) were compared. A tracter-drawn airblast sprayer calibrated to deliver 2,338 liters/ha was used to apply pesticides at one or more recommended rates on mature 'Ruby Red' grapefruit trees. Pesticides rated as highly toxic were: azinphos-methyl 50WP at 4.48 kg/ha, dicofol 4EC at 7.01 liters/ha, formetanate 92SP at 5.84 kg/ha, dimethoate 4EC at 5.85 liters/ha, malathion 57EC at 5.85 liters/ha, propargite 6.55EC at 3.51 liters/ha, benomyl 50WP at 1.68 kg/ha + ferbam 76GF at 5.60 kg/ha, ferbam 76GF at 16.81 kg/ha, carbaryl XLR plus at 18.7 liters/ha + FC435-66 petroleum oil at 46.8 liters/ha, pyridaben 75WP at 462 g/ha + FC435-66 petroleum oil at 46.8 liters/ha, carbaryl 80S at 11.21 kg/ha, ethion 4EC at 7.01 liters/ha + FC435-66 petroleum oil at 46.8 liters/ha, benomyl 50WP at 3.36 kg/ha, chlorfenapyr 2SC at 1.46 liters/ha, and pyridaben 75WP at 462 g/ha. Pesticides that were moderately to slightly toxic were: sulfur 80DF at 16.81 kg/ha, abamectin 0.15EC at 731 ml/ha + FC435-66 petroleum oil at 46.8 liters/ha, chlorfenapyr 2SC at 971 ml/ha + FC435-66 petroleum oil at 46.8 liters/ha, FC435-66 petroleum oil at 93.5 liters/ha, and chlorpyrifos 4EC at 5.85 liters/ha. Pesticides that were considered non-toxic were: FC435-66 petroleum oil at 46.8 liters/ha, carbaryl 80S at 4.48 kg/ha, chlorfenapyr 2SC at 971 ml/ha, chlorpyrifos 4EC at 5.85 liters/ha, fenbuconazole 2F at 292 ml/ha + FC435-66 petroleum oil at 46.8 liters/ha, copper hydroxide 77WP at 4.48 kg metallic/ha, benomyl 50WP at 3.36 kg/ha, and fenbuconazole 2F at 584 ml/ha. Ferbam 76GF at 16.81 kg/ha, benomyl 50WP + ferbam 76GF, carbaryl 80S at 11.21 kg/ha, carbaryl XLR Plus + FC435-66 petroleum oil, and benomyl 50WP at 3.36 kg/ha had significantly higher numbers of missing females from treated leaf surfaces suggesting these products were repellent, irritating, and/or excitatory to the gravid females.
