摘要
[目的]探究20%噻虫胺·醚菊酯SC对稻飞虱的田间防治效果。[方法]在田间条件下比较了20%噻虫胺·醚菊酯SC和25%吡蚜酮WP对稻飞虱的防治效果。[结果]20%噻虫胺·醚菊酯SC施药量在450、600 g/hm2时,药后3 d对稻飞虱的防效分别为88.77%和96.21%,药后7 d的防效分别为89.82%和92.40%,药后14 d的防效分别为92.20%和95.48%,其防治效果与目前生产上应用的吡蚜酮的防治效果基本一致。[结论]20%噻虫胺·醚菊酯SC可作为稻飞虱防治药剂的替换品种用于生产。
[Objective]The aim was to study the control effect of 20% clothianidin.ethofenprox SC against rice planthopper in field.[Method] The control effects of 20% clothianidin.ethofenprox SC and 25% pymetrozine WP against rice planthopper were compared in paddy fields.[Result] The control effects of 20% clothianidin.ethofenprox SC on rice planthopper at dosage of 450 g / hm2 and 600 g / hm2 were 88.77% and 96.21% in three days after spraying,were 89.82% and 92.40% in seven days after spraying,and were 92.20% and 95.48% in 14 days after spraying,respectively.The control effect of 20% clothianidin.ethofenprox SC on rice planthopper had no significant difference with that of 25% pymetrozine WP at dosage of 300 g / hm2.[Conclusion]20% Clothianidin.ethofenprox SC can be taken as an alternative chemical to control rice planthopper.
