Molecular formula: C₁₂H₁₅N₂O₃PS. Yellow liquid (Original is red brown oil), melting point is 6.1 ℃. Density is 1.178 g/mL (20 ℃); solubility is 1.Smg/L in water (20℃),  larger than 200g/L in Toluene, hexane, dichloromethane and isopropanol, and it is slightly soluble in aliphatic hydrocarbons, and slowly hydrolyze in vegetable oil or mineral oil and decompose gradually under ultraviolet light. 

Phoxim has a broad spectrum in insecticides, and mainly function through touch or stomach toxicity, with no internal absorption. It is pretty effective for Lepidoptera larvae. This product has a short residual period with small residual risk since it can fast decompose in the field within short-term because of its light instability property, But its residual period is long when applying in the soil, which is suitable for controlling underground pests.

It has good effects on larvae of lepidoptera pests which are harmful to peanut, wheat, rice, cotton, corn, fruit trees, vegetables, mulberry, tea and other crops; also has certain killing effect on their eggs. It can be used for controlling pests in warehouse.

Attentions:
1. Do not mix with alkaline materials.
2. Cucumbers and Kidney beans are sensitive to phoxim and are prone to phytotoxicity.
3. Phoxim is easily decomposed by sunlight, so application in fields should conduct at evening or night.
4. Sorghum is sensitive to phoxim and should not be sprayed. Corn field can only use granule form to control corn borer, do not apply spray irrigation against aphid, armyworms and so on.
5. Toxic symptoms and emergency treatment are same as other organophosphorus.
