为寻找高效低毒、低残留杀虫药剂,笔者应用25%毒死蜱·辛硫磷乳油进行了防治稻纵卷叶螟的田间小区试验,结果表明,25%毒死蜱·辛硫磷乳油72 g/667m2和80 g/667 m2与40%毒死蜱乳油30 g/667m2施药后3 d和7 d的防治效果相当,未达显著差异。大区示范结果也得到了证实。
In order to find a high efficiency, low toxicity and low residual insecticide, the author conducted a field trial of 25% chlorpyrifos and phoxim to control the rice leaf roller. The results showed that 25% chlorpyrifos phoxim 72 g / 667m2 And 80 g / 667 m2 and 40% chlorpyrifos EC 30 g / 667m2 3 d and 7 d after the control effect is not significant difference. Large-scale demonstration results have also been confirmed.
