氟啶虫胺腈50%水分散粒剂防治棉花盲蝽蟓田间药效试验研究

Study on the Field Efficacy of Sulfoxaflor 50% WG Against Adelphocoris Suturalis(Jakovlev)

试验表明,氟啶虫胺腈50%水分散粒剂防治棉花盲蝽蟓效果较好,以C处理防效达到有显著水平,其速效性、持效较好。供试药剂在试验剂量范围内对作物安全,是防治棉花盲蝽蟓较理想的药剂。

A Fieldtrial was conducted in Huanggang city, Hubei Province to determine the efficacy of sulfoxaflor 50% WG against Adelphocoris suturalis （Jakovlev）, a serious insect pest on cotton. The results showed that sulfoxaflor 50% WG provided a better control against A.suturalis compared to the control insecticide products. The highest control rate could reach when application concentration was 100a.i. mg/L. Nonegative effect to cotton development was observed during the test. Therefore, the trial conclusion was that sulfoxaflor 50% WG could be used to control A. suturalis and the reasonable range of spraying dosage was from 50-75mg a.i./L.
