Useful:

• Chemical Classes: Pesticides -> Organophosphate Insecticides
• Canonical SMILES: CC(=CC(=O)OC)OP(=O)(OC)OC
• Isomeric SMILES: C/C(=C\C(=O)OC)/OP(=O)(OC)OC
• Inhalation Risk: A harmful contamination of the air can be reached rather quickly on evaporation of this substance at 20 °C.
• Effects of Short Term Exposure: Cholinesterase inhibition. The substance may cause effects on the nervous system. This may result in convulsions and respiratory failure. Exposure far above the OEL could cause death. The effects may be delayed. Medical observation is indicated.
• Description: Pure mevinphos is a colourless liquid, while technical grade mevinphos is a pale yellow liquid with a very mild odour. It is soluble in water but very soluble in alcohols, ketones, chlorinated hydrocarbons, aromatic hydrocarbons, and many organic solvents. It is both an insecticide and acaricide. The U.S. EPA grouped mevinphos as an RUP, and hence it should be purchased and used only by certified and trained pesticide applicators. It is not registered for use in many countries including the United States. Mevinphos is used to control a broad spectrum of insects, including aphids, grasshoppers, leaf-hoppers, cutworms, caterpillars, and many other insects on a wide range of field, forage, vegetable, and fruit crops. It is also an acaricide that kills or controls mites and ticks. It acts quickly both as a contact insecticide, acting through direct contact with target pests, and as a systemic insecticide, which becomes absorbed by plants on which insects feed.
• Uses: Mevinphos is a pesticide used in the protection of crops. Insecticide. Contact insecticide and acaricide for control of chewing insects and spider mites in fruits, vegetables and ornamentals.
