摘要
根据室内生测及大田试验结果得知,百菌清是控制大白菜根肿病发生的有效药剂。直播大白菜:用60％百菌清可湿性粉剂500g/667m2,与200kg细沙拌匀,毒土法穴施, 之后用60％百菌清可湿性粉剂750倍液(800mg／kg)药液100mL灌根2次,连续3次施药, 间隔期10d,对大白菜根肿病的防效可达70％以上。
The experiment results in laboratory and field showed that the control effects of chlorothalonil WP for Cabbage Plasmodiophora brassica were satisfactory. The mixture of chlorothalonil 60% WP 500g/mu with 200kg fine particle sand was applied to the root area of sowing cabbage. After 10 days, chlorothalonil 60% WP diluted to 750 times （800mg/kg） was applied to the root area of the same sowing cabbage, once every 10 days with two consective times, The control effect was more than 70%.
