Description and Uses
Phosmet is an organophosphate insecticide and acaricide. It reduces apple damage by a large variety of insects, including apple maggots, codling moths, and obliquebanded leafrollers when used as either a border or cover spray at a concentration of 1.9 kg AI/hectare. Phosmet is effective in controlling S. scabiei in pigs when applied as a 20% pour-on solution. It is toxic to rats via oral administration (LC50 = 230 mg/kg). Formulations containing phosmet have been used in the control of insects and mites in agriculture.
Nonsystemic acaricide and insecticide used on citrus, fruit, grape and potato crop
