防除油菜田杂草药效试验结果表明:施用50%乙.异噁松EC有效成分525~1125 g/hm2后第30、60、90 d对看麦娘、网草和牛繁缕的综合密度防效分别为92.32%~100%、91.07%~99.68%、92.07%~99.83%,第90 d的综合鲜重防效高达93%以上;施用该药剂能显著提高油菜田间的透光率,降低杂草对田间养分和水分的吸收,对油菜的增产率为29.01%~29.48%。
The results of herbicide-resistant weed control rape field test showed that the application of 50% B. isoprenone EC effective components 525 ~ 1125 g / hm2 30,60,90 d on to see Anemarrhenna & The effective rate of comprehensive fresh weight control was 92.32% ~ 100%, 91.07% ~ 99.68% and 92.07% ~ 99.83% respectively, and the comprehensive fresh weight control efficiency was over 93% at the 90th day. The application of this pesticide could significantly improve the light transmittance and reduce the Grass on the field nutrient and water absorption, rape yield increase of 29.01% ~ 29.48%.
