Physical and Chemical Properties: The technical material is a brown viscous liquid with a relative density of 1.27~1.28. At 20°C, the vapor pressure > 1.33×10-8 Pa, and the volatility rate is 0.3 μg/m3 (at 40°C). It is soluble in organic solvents such as acetone, ether, toluene, and dichloromethane; slightly soluble in alcohol, insoluble in water. Stable for acidic and sunlight conditions, but unstable in alkaline environments with pH above 7.5. Enantiomer (S,1R-cis-R, 1S-cis-) m.p. 81°C, vapor pressure 10×10-9 Pa (20°C). Solubility at 20°C: toluene, dichloromethane > 200 g/L, isopropanol 5~10 g/L, hexane 2~5 g/L, water 0.005 mg/L. Enantiomer (S,1R-trans-R,1S-trans-) m.p. 106°C, vapor pressure 90×10-9 Pa (20°C), solubility at 20°C: toluene, dichloromethane, >200g/L, isopropanol 2~5g/L, hexane 1~2g/L, water 0.002mg/L.
How to use
1. Drilling pests: Such as rice borers, leafroller borers, cotton bollworm, etc. During the egg-to-egg hatching period, before larvae burrow into crops, spray water with a 2.5~emulsifiable concentrate diluted 1500~2000 times for control, evenly spraying the pesticide onto the pest-infested areas.
2. Fruit tree pests: For controlling peach fruit borers, spray 2.5% emulsifiable concentrate diluted 2,000~4,000 times, or spray with 2.5% emulsifiable concentrate 25~500mL per 100L of water. Controls the golden striped moth. During peak adult emergence or egg hatching period, apply 2.5% EC diluted 1000~1500 times, or add 50~66% 2.5% EC per 100L of water. 7mL spray.
3. Vegetable pests: To control cabbage worms, control must be done before larvae reach 3rd instar. On average, each cabbage plant has one worm to start pesticide application, spraying 2.5% emulsifiable concentrate at 26.8~33.2 mL/667m2 with 20~50 kg of water. Aphids must be controlled before major outbreaks, with spraying the solution evenly on the pest body and affected areas.
4. Underground pests: For grubs, mole crickets, needle worms, and cutworms, or wheat seeds, mix seeds with 80~160mL of 12.5% suspension agent. When mixing seeds, first mix the required solution with water, then pour in the seeds and stir evenly so the pesticide coats the seeds evenly. Pile and let it sit for 2~4 hours before sowing. It can control underground pests.
