摘要
为明确药剂拌种对小麦瑞典蝇的防治效果,对吡虫啉、七氟菊酯等6种常用拌种剂进行了药效对比试验。结果显示,以0.2%吡虫啉效果最佳,播种30 d后调查,防效仍在90.85%,且对出苗有一定促进作用。七氟菊酯的持效期也较长,播种30 d后调查,0.1%、0.2%和0.3%3种剂量的防效均在80%以上。播种后13 d调查,以0.3%七氟菊酯防效最高,其次为0.2%吡虫啉,分别为96.60%和93.01%,但前者对出苗有较强抑制作用,相对出苗率较对照降低31.39%。
In order to determine the control effect of seed treatment on frit flies, six different pesticides was compared. The results showed that 0. 2% imidacloprid was the best, with the control effect at 90.85% in 30 days after sowing. And it had promotional effect on emergence. The tefluthrin also had a longer persistent period. The control effects at three different concentration treatments （0. 1%, 0. 2% and 0. 3%） were all over 80% in 30 days after sowing. 0. 3% tefluthrin had the best control effect （96. 60%）, followed by 0. 2% imidacloprid （93. 01%） in 13 days after sowing. But 0. 3% tefluthrin had apparent inhibition effects on emergence and decreased it by 31. 39%, compared with the control.
