试验结果表明 ,75 %百农思水分散粒剂对玉米田禾本科杂草和阔叶杂草均有良好的防除效果 ,对阔叶杂草防除效果好于禾本科。百农思与乙草胺混用可以降低百农思的用药量 ,还能提高对禾本科杂草的防除效果。虽然各剂量处理区对玉米幼苗有药害 ,但是恢复较好 ,对玉米产量没有影响。玉米播后苗前土壤处理 ,适宜的用药量应为 75 %百农思水分散粒剂单用 180g/hm2 ,混用剂量为 75 %百农思水分散粒剂 12 0～ 15 0g/hm2 混加 5 0 %乙草胺乳油 15 0 0～ 195 0ml/hm2 。
The test results showed that 75% Bai Nong Si water dispersible granules on grass weeds and broad-leaved weeds in corn field have good control effect, broad-leaved weeds control better than Poaceae. Bainone and Acetochlor mixed can reduce the dosage of 100 Nong Si, but also improve the control effect on grass weeds. Although each dose treatment area had phytotoxicity on corn seedlings, the recovery was better and had no effect on the yield of corn. Maize sowing seedlings before soil treatment, the appropriate dosage should be 75% 100% Granville Sisi dispersible granules used alone 180g / hm2, the mixed dosage of 75% 100% Granville water dispersion Granules 12 ~ 15 0g / hm2 mixed 5 0% acetochlor EC 15 0 0 ~ 195 0ml / hm2.
