目前,南阳地区大面积防治小麦粘虫,仍依懒666、DDT 等化学农药,这不仅增加了小麦的生产投资,还由于农药的残毒,严重影响小麦品质和污染环境。为了解决这些问题,我们曾试验推广了小谷草把诱卵,防治麦田粘虫,收到一定效果。但由于在诱卵过程中需进行三次插换草把,在推广应用中尚有困难。近两年,我们试用药浸草把,杀死产在药草把上的粘虫卵和初孵幼虫,从而延长草把的使用时间,减少插换草把次数。如果选用药效可维持二十天以上的药剂,再
At present, large-scale control of armyworm in Nanyang still depends on chemical pesticides such as lazy 666 and DDT, which not only increase wheat production investment but also seriously affect the quality of wheat and pollute the environment due to the residue of pesticides. In order to solve these problems, we have tried to popularize the ovules and control the armyworm in the field and get some results. However, due to the need for three intercalations during the process of ovulation, it is still difficult to promote the application. In the past two years, we have tried to use herbicide to kill the armyworm eggs and newly hatched larvae which are produced on the herb stems, thus prolonging the service life of the grass and reducing the number of grass weeds. If the choice of efficacy can maintain more than twenty days of the drug, and then
