Common name: Alpha–Cypermethrin Other name: Fastac, Bestox, Fendona HazardClass: 6.1b Packing Group: Ⅲ Chemical name: Cyano-3-phenoxybenzyl 3-(2,2-dichlorovinyl)-2,2- dimethylcyclo-propane carboxylate CAS NO.: 67375-30-8 Molecular Formula: C22H19Cl2NO3 Molecular weight: 416.30 Specification: TC purity≥97%，Moisture≤0.25%，Acidity（vitriol）≤0.25%， Formulation:5％,10％,25％ EC；5%、10% SC；5％ WP physicochemical property: Technica is white powder, melting point 78-81 ℃, boiling point 200 ℃ / 9.3 Pa, vapor pressure and Pa (20 ℃), under normal temperature in water solution. Solution degree is extremely low, soluble in ketone, alcohol and aromatic hydrocarbon solvent, in neutral and acidic conditions stable, in alkali condition hydrolysis, add heat to 200 ℃ stability is good Poisonousness: Cis cypermethrin for medium toxicity pesticides. Technical to rats LD50 through the mouth for 60-80 mg/kg, rat acute percutaneous LD50 for 500 mg/kg, rabbit acute percutaneous LD50 > 2000 mg/kg, in test dose not seen chronic accumulation and teratogenic, mutagenic and carcinogenic effect,it has high poison to fish and bee. Application: To insects have high stomach toxicity and tag function, down quickly, with kill egg activity. This product to field crop, economic crops, vegetables, fruit trees and health pests have special effects, can be widely used in cotton crop pests on most of the control. On plants have good stability, Can an tirain water erosion, cis cypermethrin is cypermethrin of cis isomer, insecticidal activity about cypermethrin 1 ~ 3 times. For some harm insect eggs have kill effect, resistant to organophosphorous pests effect is good. Packing: TC:25 kg/Fiber drum; EC and SL : 200 L /iron drum; Powder:25kg/bag Or as customerized
