Methomyl is used as a pesticide on commercial fruit and vegetable crops as well as stored products. Its application as an insecticide is highly effective against a wide variety of pests, particularly those that are resistant to organophosphorus pesticides.
Methomyl is readily absorbed through the skin and by inhalation of fine particles. Its mechanism of action is to inhibit cholinesterase, an enzyme produced in the liver that regulates nervous system functioning. The telltale symptoms of toxicity by this route are uncontrolled muscle movements, spasms, convulsions, etc.
Methomyl is classified as a carbamate insecticide and it dissolves in water and breaks down rapidly in soil, so it has a low persistence in the environment.
Biochemistry Cholinesterase inhibitor.
Mode of action

Control of a wide range of insects (particularly Lepidoptera, Hemiptera, Homoptera, Diptera and Coleoptera) and spider mites in fruit, vines, olives, hops, vegetables, ornamentals, field crops, cucurbits, flax, cotton, tobacco, soya beans, etc. Also used for control of flies in animal and poultry houses and dairies.
