| 摘 要： | 25%异丙隆WP对麦田牛繁缕、看麦娘、菵草的防效均在85%以上，而6.9%骠马胶悬剂对牛繁缕的防效仅为20.66%，85%甲磺隆钠盐对菵草的防效为26.39%。施用异丙隆900ga.i./hm^2时，25%异丙隆WP对麦田杂草的综合防效为85.29%；50%异丙隆WP和75%异丙隆WP对麦田杂草的综合防效分别为92.1%和95.8%，在相同剂量下，药效差异不显著，但显著高于25%异丙隆WP的药效；采用扇型喷头与细孔喷头喷施异丙隆防除麦田杂草的效果一致，而扇型比细孔喷头可节时7.33-11.73h/hm^2。 |

| Abstract: | The control effects of isoproturon WP on weeds in wheat field were tested.The control efficiency of 25% isoproturon WP on Malachium aguaticum(L.) Fries,Beckmannia aequalis was over 85%,while 6.9% Puma Super on Malachium aguaticum(L.) Fries was 20.66%,85%sodium metsulfuron-methyl on Beckmannia aequalis was 26.39%.The control effects of 50% isoproturon WP and 75% isoproturon WP were significantly different with 25% Isoproturon WP.The efficacy of spraying with eyelet spray nozzle was higher than sprayer with sector spray nozzle. |
