Melting point is 80.5 ℃ (pure), 60-80 ℃ (technical), density is 1.12. The water solubility is 0.004 mg/l (pH 7), in acetone, chloroform, cyclohexanone, xylene > in 450 g/l (20 ℃), the methanol 337 g / 1 (20 ℃), n-hexane 103 g / 1 (20 ℃), in a neutral and weak acid medium relative stability. Poisonousness: Acute through the mouth LD50: rats 250-4150 mg/kg (technical), mice 138 mg/kg. Acute percutaneous LD50: rat > 4920 mg/kg, rabbit > 2460 mg/kg. To the rabbit skin and eyes have slight stimulation, the skin of weak allergic. Rat acute inhalation t.urticae (4h) 2.5mg/l. Wild duck acute through the mouth LD50 > 10000 mg/kg, the chicken > 2000 mg/kg. Rainbow trout t. urticae (96 h) 0.69 mg/l, in field condition next, using normal agricultural use dose, the fish without danger. Water flea t. urticae (48 h) 0.15 mg/l. In laboratory tests, the bees high poison, but in the field the recommended dose when using no danger, LD50 (24 h) (through the mouth) 0.035 mg/bee, (local) 0.02 mg/bee. Application: This product is high efficiency, broad spectrum and low residual strain light stability of pesticides, has strong tag and stomach toxicity action. Efficacy is better than that of chlorine chrysanthemum ester, for some insect pests have killed egg effect, still for some insect pests have food refusal activity, to lepidoptera pests with very highly active, mainly used for cotton, vegetables, fruit trees and crops on the pest control, is the high toxic pesticide dosage after the largest pesticide varieties, also used for the prevention and control of a variety of livestock pests and disease medium Queensland insect (mosquitoes, flies, cockroaches, etc.), the effect of 4 weeks or more, the termites, yellow mosquito, furniture silverfish and have very good control effect.
