摘要
采用田间小区试验,考察7种杀虫剂对稻纵卷叶螟的防治效果。试验结果表明:40%氰虫·甲虫肼SC 600 mL/hm^(2)处理对稻纵卷叶螟表现出良好的速效性和持效性,药后14 d的杀虫效果和保叶效果分别达到86.67%和86.25%,生产上有较大的推广应用价值。25%乙基多杀菌素WG 150 g/hm^(2)和15%多杀·茚虫威SC 300 mL/hm^(2)处理防效也较好。
Field trials were carried out to investigate the control effects of seven insecticides against Cnaphalocrocis medinalis.The results showed that at the dosage of 600 mL/hm^(2),metaflumizone+methoxyfenozide 40%SC had good quick efficacy and persistent control effect on Cnaphalocrocis medinalis,with the control effect and the leaf protection effect of 86.67% and 86.25% on the 14th day after treatment.It was worth promoting and applying in rice production.Spinetoram 25%WG 150 g/hm^(2) and spinosad+indoxacarb 15%SC 300 mL/hm^(2) also had good control effects.
