Biochemistry Cholinesterase inhibitor. Mode of action Non-systemic insecticide and acaricide showing localised penetration of plant cuticle; with contact and stomach action. Uses A non-systemic acaricide and insecticide used primarily in pome and stone fruit trees. Effective against Coleoptera, Homoptera (Aphididae), Lepidoptera (Cydia pomonella) and Thysanoptera on fruit trees. It is selective of most beneficial insects and widely used in integrated pest management programmes. Also used in grapes, oilseed rape, ornamentals, potatoes and vegetables. Phytotoxicity Non-phytotoxic when used at the recommended application rates. At higher application rates, Golden Delicious and other yellow apple varieties have been injured. Formulation types EC; SC; WP.
