温室粉虱是设施蔬菜、观赏花卉的主要害虫之一。实验室内进行了哒螨灵、异丙威对温室粉虱的多配组生物活性测定,筛选出3%与9%组配增效明显,LC50值为67.1998mg/kg,共毒系数为125.22。应用12%哒·异丙烟剂(FU)630～720ga.i./hm2于温室黄瓜上烟熏处理,药后1d对温室粉虱控制效果高达93.23%～97.60%,药后7d尚维持在81.51%～84.08%;且对蚜虫、螨类有较好效果。
Greenfly whitefly is one of the major pests for planting vegetables and ornamental flowers. In the laboratory, pyridaben and isoprocarb were used to determine the bioactivity of multifuntional group of whiteflies, and 3% and 9% of them were screened for synergism. The LC50 value was 67.1998mg / kg and the co-toxicity coefficient was 125.22 . Application of 12% daunasan (FU) 630 ~ 720ga.i./hm2 on greenhouse cucumber smoked, 1d after the control of greenhouse whitefly as high as 93.23% ~ 97.60%, 7d after the drug is still maintained at 81.51% ~ 84.08%; and aphids, mites have good results.
