我省自推广666、滴滴涕等有机氯农药颗粒剂防治玉米螟以来,效果很好,但由于药性稳定,不易分解,而形成积累性的残毒,常使所收玉米的籽粒和秸秆带有残毒,土壤中亦有残毒。为了寻找取代666、滴滴涕的新农药,近两年我们作了以下试验,取得了初步结果。 Since the promotion of 666 in our province, such as DDT and other organochlorine pesticide granules control corn borer, the effect is very good, but because of stable drug stability, not easy to decompose, and the formation of cumulative residual poison, often received corn grain and straw with residue, There are also residues in the soil. In order to find new pesticides that replace 666 and DDT, we have made the following tests in the past two years and achieved preliminary results.
