• Inhalation Risk: A harmful concentration of airborne particles can be reached quickly on spraying or when dispersed, especially if powdered.
• Effects of Short Term Exposure: The substance may cause effects on the nervous system. This may result in convulsions and respiratory depression. Cholinesterase inhibition. The effects may be delayed. Medical observation is indicated.
• Effects of Long Term Exposure: The substance may have effects on the nervous system. This may result in weakness. Cholinesterase inhibition. Cumulative effects are possible. See Acute Hazards/Symptoms.
• Description: 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.
• Uses: Nonsystemic acaricide and insecticide used on citrus, fruit, grape and potato crop Phosmet is used to control a wide range of insects and mites in fruit, potatoes, sweet potatoes, vines, cotton and many other crops. It is also used as a veterinary ectoparasiticide. Phosmet is used as a pesticide to protect crops and vegetation. Insecticide. Insecticide, acaricide.
