选用12%哒螨·异丙威烟剂4 500,6 000,7 500 g/hm2对棚栽黄瓜上的烟粉虱进行防治试验,并对黄瓜上残留进行快速测定。结果表明:12%哒螨·异丙威烟剂不同剂量处理对烟粉虱均有很好的防治效果。药后1 d,防效为97.2%~99.0%;药后4 d,防效为88.2%~94.4%。残留快速检测结果表明,在试验剂量下,能够检出农药残留,但在允许范围之内。
The control experiment of B. tabaci on greenhouse cucumber with 4 500,6 000,7 500 g / hm 2 of 12% pyridaben was carried out, and the residue on cucumber was determined rapidly. The results showed that: 12% pyridaben IPF different doses of the treatment of Bemisia tabaci have a very good control effect. After 1 d, the control effect was 97.2% -99.0%. After 4 days, the control effect was 88.2% -94.4%. Rapid residue test results show that the pesticide residues can be detected at the test dose, but within the allowable range.
