| Abstract: | The result of field trial showed that 0.1% matrine oxide liquid had highly activity to control cabbage worm, and had long effective control time. In field experiments with matrine oxide liquid at the dosage of 80 - 200mL/hm^2, cabbage worm mortality rate was 94.36% to 99.27% 3 days after treatment and more than 99.08% 7days after treatment .Compared with other pesticides, the pesticide has obvious effect. Its suitable dosage was 150mL/hm^2, with no cabbage injury. This pesticide could apply to the nuisance free vegetable production. |
