为了筛选出防效好、经济安全的农药品种,进行了施用20、40、60 mL/667m2的1%申嗪霉素悬浮剂(增强型)、以100 mL/667m2的20%甲基立枯磷乳油和清水为对照,对棉花枯.黄萎病的防效对比试验。试验结果表明,施用1%申嗪霉素悬浮剂(增强型)防治棉花枯.黄萎病效果较好,防效高达69.23%;比对照增产28.8 kg/667m2;且在20～60 mL/667m2的浓度范围内不会对棉花产生明显的药害,对有益生物无不良影响。因此,1%申嗪霉素悬浮剂(增强型)值得在棉花枯.黄萎病发生区大面积推广使用,建议施用剂量以40～60 mL/667m2为宜。
In order to screen out the pesticide varieties with good control effect and economic security, we applied 20,40,60 mL / 667m2 of 1% sodiunmycin suspension (enhanced) to 100 mL / 667m2 of 20% Phospholipid and water as a control, the control of cotton withered wilt disease control experiment. The results showed that the application of 1% sizofenacin suspension (enhanced) could prevent and cure cotton yellow, Verticillium wilt, the control effect was as high as 69.23%, 28.8 kg / 667m2 more than the control and 20-60 mL / 667m2 Of the concentration range will not produce significant phytotoxicity on cotton, no adverse effects on beneficial organisms. Therefore, 1% of ShenZhenYang suspension (enhanced) is worth in the area of withered Verticillium wilt occurred in large areas to promote the use of recommended dosage to 40 ~ 60mL / 667m2 appropriate.
