[目的]评价氟吡呋喃酮对柑橘木虱的防治效果,为生产上应用提供科学依据。[方法]依照田间药效试验准则进行田间药效试验。[结果]17%氟吡呋喃酮可溶性液剂50、66.7、100 mg a.i./kg在药后3、7、14 d的田间防效均高于88.5%,甚至高达100%,至药后21 d,防效依旧高达98.4%~100%,表现出良好的速效性和持效性,与对照药剂21%噻虫嗪悬浮剂50.0 mg a.i./kg处理效果相当,对柑橘无药害。[结论]建议在柑橘新梢抽发期,柑橘木虱若虫初发生时,使用17%氟吡呋喃酮可溶性液剂50~100 mg a.i./kg喷雾为宜。
[Objective] The research aimed to evaluate the control effect of flucopyrolone on citrus psylla, and provide a scientific basis for its application. [Method] The field efficacy test was conducted according to the field efficacy test. [Result] The control efficacy of 17% fumagillone soluble liquor 50, 66.7 and 100 mg ai / kg were 88.5% and even up to 100% on the 3rd, 7th and 14th days after treatment, respectively. , The control effect is still as high as 98.4% ~ 100%, showing good quick-acting and persistence. It is equivalent to the control agent 50.0 mg ai / kg of 21% thiamethoxam suspension and has no phytotoxicity to citrus. [Conclusion] It is advisable to spray 17 ~ 50% of fumagillone soluble liquid 50 ~ 100 mg a.i./kg at the beginning of citrus psyllids nymphs during the period of citrus shoot shoot development.
