Field Efficacy and Appraisal of Various Insecticides on Rice Planthopper
【摘要】 为明确10种杀虫剂对稻飞虱的田间防效及安全性,采用田间茎叶喷雾法检测防治效果,以邓肯氏新复极差法检验差异显著性。结果表明:20%异丙威乳油、50%敌敌畏乳油速效性较好,药后1 d的防效为75.61%~80.78%,与其它药剂处理差异显著;10%烯啶虫胺可溶液剂、25%吡蚜酮可湿性粉剂、20%呋虫胺可溶粒剂、50%氟啶虫胺腈水分散粒剂、50%噻虫胺水分散粒剂持效性较好,药后14 d的防效为85.37%~94.16%,与其它药剂处理差异显著。烯啶虫胺、吡蚜酮、呋虫胺、氟啶虫胺腈、噻虫胺是生产上防治稻飞虱的理想药剂。
【Abstract】 In order to confirm the efficacy and safety of ten kinds of insecticides for controlling rice planthopper in rice field,the experiment was carried out by the method of spraying on stems-leaves of rice,and the experiment data were analyzed by Duncan’s new multiple range test. The results indicated that isoprocarb 20% EC and dichlorvos 50% EC exhibited rapid effect,with efficacies of 75.61%-80.78% on the 1st day after spraying. Nitenpyram 10% SL,pymetrozine25% WP,dinotefuran 20% SG,sulfoxaflor 50% WG and clothianidin 50% WG had good durable effect,with efficacies of 85.37%-94.16% on the 14 th day after spraying. The ten kinds of insecticides could control rice planthopper. The insecticides of nitenpyram,pymetrozine,dinotefuran,sulfoxaflor and clothianidin had better effects among the ten kinds of insecticides,and could be applied and extended in rice.
