摘要
在水稻移栽田进行试验研究,结果表明院52%吡嘧·二氯喹可湿性粉剂防除水稻移栽田一年生杂草的有效成分适宜剂量为312～390 g/hm^2;在水稻移栽后7～15 d、稗草二至三叶期施药,全草株防效可达94.5%～96.5%,与对照药剂10%吡嘧磺隆可湿性粉剂、50%二氯喹啉酸可湿性粉剂的防效差异极显著。
The test in transplanted rice fields was done.The results showed that the suitable dosage of effective components was 312-390 g/hm^2 about 52% pyrazosulfuron-two chloroquine WP controlling annual weeds of transplanted rice fields;after rice transplanting 7 ~ 15 days, and spraying when 2-3 leaf of barn-yardgrass,the whole grass control effect could reach 94.5%-96.5%, the differences about the effect of prevention and cure were very significant with the contrast agent of 10% pyrazosulfuron ethyl WP and 50% two Chloroquine WP.
