建昌地区亚洲玉米螟危害逐年增加,成为制约玉米增产的瓶颈,为此,我们对防治玉米螟具有防效的四种杀虫剂进行了田间试验,旨在为今后建昌地区防治玉米螟提供参考。1试验材料供试药剂为25%甲基异柳磷颗粒剂、1.5%辛硫磷颗粒剂、2.5%杀螟灵一号颗粒剂、3.6%杀虫双颗粒剂。试验于2010-2011连续两年在葫芦岛市建昌县农业技术推广中心示范场进行试验田,前茬冬闲田,地力中上,肥水管理较好。播种时间4月20日,
In Jianchang area, the damage of Asian corn borer increased year by year, which became the bottleneck restricting the yield increase of corn. Therefore, we conducted field experiments on four kinds of insecticides to prevent and control corn borer, and aimed to provide the future control of corn borer in Jianchang area reference. A test material for the test agent is 25% methyl isophthaldehyde granules, 1.5% phoxim granules, 2.5% Kill Borelli granules, 3.6% insecticidal double granules. The experiment was carried out in 2010-2011 for two consecutive years in Jianchang County Agricultural Technology Extension Center demonstration field in Huludao City. Before the crop was idle in winter, the soil fertility and water management were good. Seeding time April 20,
