Chlorantraniliprole technical, 35% water dispersible granule, 200g / L ~, floating agent and 5% suspension agent are all micro toxic insecticides.
Environmental and biological safety evaluation: chlorantraniliprole 35% WG on rainbow trout LC ∞ (96h) > 3.2mg/l (the maximum solubility of chlorantraniliprole in water is 3.18mg/l); quail LD50 > 250mg A.I. / kg; bee LD50 (48h) 340.5g, bee (> 119.191xga. I. / bee), ld5o (48h) > 285.7g/bee The LC50 of silkworm was 0.0182 mg / L. Toxic to fish or below; low toxic to birds and bees: highly toxic to silkworm, high risk. LC50 of chlorantraniliprole 200g / L SC to rainbow trout (96h) > 9.4mg/l (1.73mga. Ill); LD50 of quail (2000mga. I. / kg); LD50 of bee (114.1inga. I. / bee), LD50 of bee (1001xga. I. / bee); LC50 of silkworm (0.0166mg / L). Toxic to fish, low toxic to birds and bees, highly toxic to silkworm. When using, it is forbidden to use it near silkworm room and mulberry garden; it is forbidden to clean
Pesticide applicators in water area such as pond.
Application: chlorantraniliprole is a broad-spectrum insecticide of o-formylaminobenzamide, which is mainly used to control Lepidoptera pests of many crops, and also has good control effect on other pests. The mechanism of action is to activate Rankine receptors, release calcium stored in smooth muscle and striated muscle cells, and cause muscle weakness and numbness until the death of pests. The main mode of action was stomach toxicity and contact toxicity. Chlorantraniliprole can permeate the plant through the surface of stem and leaf. It can also be absorbed by root and moved in xylem. The results showed that chlorantraniliprole 35% WG had higher activity and better control effect on Plutella xylostella and oriental fruit moth. The concentration of chlorantraniliprole 35% WG was 14-20mg / kg (equivalent to 17500-25000 times of commercial dilution of 35% WG): peach The dosage of the moth was 35.50 mg / kg (converted into 35% WG commercial diluted 7000-10000 times). Spray the stem and leaf evenly at the peak period of the moth and the early stage of the moth oviposition, and spray twice, with an interval of 14 days. Chlorantraniliprole 200g / L SC had higher activity and control effect on Cnaphalocrocis medinalis. The dosage of chlorantraniliprole 200g / L SC was 15-30g (active ingredient) / HM (converted into 200g / L, @, the commercial quantity of SC was 5-1og / 667m). The method of application was stem and leaf spray, and the maximum number of application was 2 times, with an interval of 7 days. Chlorantraniliprole 5% SC had high activity and control effect on Spodoptera exigua and Plutella xylostella. The dosage of chlorantraniliprole 5% SC was 22.541.25g (active ingredient) /} LM (converted into 5% SC, the commercial dosage was 30-55g / 667m, diluted with 50L water). Spray evenly at the peak of egg hatching. If it was serious, spray it 7 days later The spray was repeated once. In the range of dosage, it is safe to crops, and there is no harm. It has low toxicity or no effect on predatory and parasitic natural enemies.
