花生根结线虫病在我区发生为害甚烈。据湛江地区农科所83年早造对雷州半岛三县一市(徐闻、海康、遂溪、湛江市郊)的初步调查,花生根结线虫病发生为害面积约占4成多,受害田生长很差,产量很低。多年来的生产实践证明,防治花生根结线虫病已成为花生生产能否上得去的急须解决的问题之一。 为了加速防治工作开展,为大面积推广使用提供依据,84年早造,我们对法国罗纳普朗克公司产的20％益收宝进行了田间小区药效试验,并取得初步结果。
Peanut root knot nematode disease is very harmful in our district. According to a preliminary investigation conducted by Zhanjiang Agricultural Research Institute in early 1983 on the three counties and one city of Leizhou Peninsula (Xuwen, Hikang, Suixi and Zhanjiang suburbs), about 40% of the pest root-knot nematodes disease area was affected, Very poor, yield is low. Years of production practice has proved that prevention and control of peanut root-knot nematode disease has become a peanut production can go on the urgent need to address one of the problems. In order to speed up the prevention and control work and provide the basis for popularizing and using it in large area, we made a field trial of 20% Yibao Bao produced by France Lonoplank Company in 1984 and achieved preliminary results.
