Abstract
The efficacy test of 6% polyaldehydes carbaryl on the control of cabbage snail was carried out in this study. The results showed that 6% polyaldehydes carbaryl WDG had good and fast effect for controlling cabbage snail. Its doge of 750 g/667 m2, 600 g/667 m2 used in early period of insect attack could reach the controling efficiencies of 94.96% and 91.28% respectively after 5 d, it was higher than doge of 450 g/667 m2 of 6% polyaldehydes carbaryl and 6% tetracetaldehyde carbaryl, granular（CK）. The doge of 750 g/667 m2 of 6% polyaldehydes carbaryl still maintianed the controling efficiency of 95.03% after 10 d. In the production practice, it was suggested that the cabbage snail could be controlled by applying 750 g/667 m2 of 6% polyaldehydes carbaryl in early period of insect attack.关键词
