摘要
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。其中,20%呋虫胺SC、50%氟啶虫胺腈WG和5%啶虫脒EC对甘蔗蓟马防治效果最好,药后10天防效达80%以上,且与300 g/L氯虫·噻虫嗪SC防效间无显著差异,可用于甘蔗蓟马防治;50%吡蚜酮WG、10%氯噻啉WP虽与300 g/L氯虫·噻虫嗪SC防效间存在显著差异,但其防效亦接近80%,可用作轮换使用农药。
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.
