选用阿维菌素2%乳油和苏云金杆菌8000IU/mg可湿性粉剂进行防治稻纵卷叶螟田间试验,药后13d调查结果表明,使用阿维菌素2%乳油20、30mL/667m2和苏云金杆菌8000IU/mg可湿性粉剂200g/667m2防效均在90%以上。阿维菌素2%乳油30mL/667m2的防效与生产上常用的有机磷类农药毒死蜱480g/L乳油常用剂量的防效无显著差异。是防治稻纵卷叶螟的理想替换农药,可和其他农药轮换使用,以延缓稻纵卷叶螟对单一农药的抗药性。
Avermectin 2% EC and Bacillus thuringiensis 8000IU / mg WP were selected to control the rice leaf roller. The results of 13 days after treatment showed that the use of avermectin 2% EC 20,30 mL / 667m2 and Bacillus thuringiensis 8000IU / mg wettable powder 200g / 667m2 control effect is above 90%. Avermectin 2% EC 30mL / 667m2 control effect and production of organic phosphorus pesticide commonly used chlorpyrifos 480g / L EC commonly used dose control effect was no significant difference. It is an ideal replacement pesticide for control of rice leaf roller, and can be used in alternation with other pesticides to delay the resistance of rice leaf roller to single pesticide.
