采用单相油悬浮剂加工技术研制出1.82%胺.氯烟剂,且在生产上用1.5 kg/667m2进行杨梅果蝇防治试验。结果表明:药后24 h时对果蝇成虫的防效达80.00%~90.00%,48 h时防效为61.54%~81.82%;对幼虫的控制效果:鲜果为85.71%~87.64%,落地果为58.97%~85.94%。药后48 h,果实农药残留不超限量标准,符合产品安全标准。
The single-phase oil suspension processing technology was used to develop 1.82% amine, chlorine and smoke agent, and 1.5 kg / 667m2 was used in the production to prevent and cure the bayberry fruit fly. The results showed that the control effect on adult adults of Drosophila was 80.00% -90.00% at 24 h and 61.54% -81.82% at 48 h. The control effects on larvae were 85.71% -87.64% for fresh fruits, For 58.97% ~ 85.94%. 48 h after treatment, the pesticide residues in fruit should not exceed the limit of the standard, in line with product safety standards.
