Abstract
The experiment of 2.5% Cyhalothrin Microemulsion on cabbage worm in open field was carried out. The results showed that 2.5% Cyhalothrin Microemulsion had good effect to control cabbage worm with long control time. Using 2.5% Cyhalothrin Microemulsion with dosage of 25 g/667 m2, the cabbage worm mortality was 97.9% after 3 days, and 94.3% after 7 days. Compared with other pesticides, it had obvious effect. The suitable dosage was 20-25 g/667 m2, with no cabbage injury. This pesticide could be applied to the environment-friendly vegetable production.
