5种杀虫剂对甘蔗蓟马的田间防治效果

为筛选高效低毒并对甘蔗安全的防治甘蔗蓟马药剂,本文开展了10％氯噻啉WP、20％呋虫胺SC、50％氟啶虫胺腈WG、50％吡蚜酮WG、5％啶虫脒EC对甘蔗蓟马的田间防治效果试验,并用已登记防治甘蔗蓟的300 g/L氯虫·噻虫嗪SC药剂作为对照分析试验结果.结果表明,供试的5种农药均对甘蔗蓟马有较好的防治效果且对甘蔗安全....

The Field Control Effects of Five Insecticides against Sugarcane Thrips

The aim of this study was to screen insecticides with high efficiency,low toxicity and safety to sugarcane thrips.The field control effects of 10%Imidaclothiz WP,20%Dinotefuran SC,50%Sulfoxaflor WG,50%Pymetrozine WG and 5%Acetamiprid EC on sugarcane thrips were analyzed,and the results were compared with 300 g/L Chlorantraniliprole-thiamethoxam SC registered in China.The results showed that the five insecticides had good control effect against sugarcane thrips and were safe to sugarcane.20%Dinotefuran SC,50%Sulfoxaflor WG and 5%Acetamiprid EC had the best control effect against sugarcane thrips,which could be used for sugarcane thrips control.The control effect was more than 80%at 10 days after treatment,and there was no significant difference between them and 300 g/L Chlorantraniliprole-thiamethoxam SC.The control effect of 50%Pymetrozine WG and 10%Imidaclothiz WP was significantly different from that of 300 g/L Chlorantraniliprole-thiamethoxam SC,but the control effect was close to 80%,which could be used as rotation insecticides against sugarcane thrips.
