为筛选兼具速效性与持效性的柑橘木虱防治药剂,选择6%阿维·噻虫嗪微乳剂、30%噻虫胺悬浮剂、34%啶虫脒·毒死蜱乳油、26.9%石英水剂、2.5%高效氟氯氰菊酯水乳、21%噻虫嗪悬浮剂进行田间药效试验。结果表明,供试的6种杀虫剂中,防治柑橘木虱速效性最好的是21%噻虫嗪悬浮剂,在药后24 h对该虫防效达92.14%;6%阿维·噻虫嗪微乳剂、30%噻虫胺悬浮剂和26.9%石英水在施用后1~5d的防效呈上升趋势,这3种药剂到药后第5天的防治效果在88.81%~94.08%之间;6%阿维·噻虫嗪微乳剂对柑橘木虱的持效性较好,在药后第5天的防效达到94.08%。
In order to screen the citrus psyllid control agent which has both quick and effective effect, we selected 6% Aviclovir microemulsion, 30% Clothianidin suspension, 34% acetamiprid chlorpyrifos EC, 26.9% quartz water Agent, 2.5% beta-cypermethrin milk, 21% thiamethoxam suspension field efficacy test. The results showed that among the six insecticides tested, the best 21% thiamethoxam suspension was the most effective in controlling citrus psylla, and the control effect was 92.14% Thiamethoxam microemulsion, 30% clothianidin and 26.9% quartz water after 1 to 5 d showed an upward trend of control. The control efficacy of these 3 agents to the 5th day after drug administration ranged from 88.81% to 94.08% 6% Avicenothiazide microemulsion had good effect on Citrus psyllid, and the control efficacy reached 94.08% on the 5th day after treatment.
