摘要
苦皮藤素微粉剂1和微粉剂2以不同的浓度混入玉米中,当使用剂量为1000mg/kg时,对玉米象成虫的种群繁殖抑制率分别为96.66%和96.02%,能有效控制玉米象成虫的危害,但对幼虫和卵的控制效果不明显。
Micro granule 1 and Micro granule 2 were made of Celangulin,to mix in different prescription of micro granule in corn,when the applied does reached 1 000 mg/kg,the ratio of breeding inhibition was differently 96.66% and 96.02%,worm of Sitophilus zeamais Motschulsky could be controlled.But in the period of egg and nymphs,it could hardly be controlled in the same concentration.
