摘要
60%百泰水分散粒剂防治大白菜炭疽病的田间试验结果表明,2007年秋季用药,第3次施药后7 d,该药剂每667 m2使用40、60、100 g的防效分别为84.12%、88.69%和95.4%;2008年夏季用药,其防效分别为91.42%、94.84%和97.04%,均明显高于对照药剂25%凯润乳油(每667 m2使用25 g)和70%品润干悬浮剂(每667 m2使用170 g)的防效。因此,60%百泰水分散粒剂对大白菜炭疽病具有良好的防治效果,建议田间防治制剂每667 m2使用40 g(有效成分24 g)。
The field test results of 60% Baitai WG against Chinese cabbage anthracnose showed that the control efficiency of the fungicide with 40,60 and 100 g/667m2 were 84.12%、88.69% and 95.4% respectively at the 7th day after the third spraying,during the Autumn of 2007,and that were 91.42%、94.84% and 97.04% respectively,during the Summer of 2008.All of them were higher than that of 60% Cabrio EC(25 g/667m2)and 70% Polyram DF(170 g/667m2).Therefore,60% Baitai WG had a better control efficiency against Chinese cabbage anthracnose,and the application amount of 40 g/667m2 of the fungicide(ai 24 g/667m2)was suggested in field.
