小区试验结果,花生芽前喷施除草剂42%乙·恶乳油1125~1500mL/hm2对花生安全。药后20d对单、双子叶杂草的防效分别为94.8%~97.4%、85.7%~92.8%;药后50d的防效分别为92.9%~95.3%、87.2%~91.1%;鲜重总防效96.83%~97.0%。荚果增产229.6%~230.4%。明显优于50%乙草胺乳油对双子叶杂草的除草效果(78.6%~61.3%)。
Community test results, peanut buds sprayed with 42% of the first B EC # 1125 ~ 1500mL / hm2 on peanut safety. The control effects of single weaned and dicotyledonous weeds were 94.8% -97.4% and 85.7% -92.8% at 20 days after treatment, respectively. The control effects were 92.9% -95.3% and 87.2% -91.1% Control efficiency 96.83% ~ 97.0%. Pod yield 229.6% ~ 230.4%. Significantly better than 50% acetochlor EC on dicotyledonous weeding effect (78.6% ~ 61.3%).
