DDVP—盖膜和几种杀线虫剂防治花生根结线虫(Meloidogyne arenaria)病研究

STUDY ON CONTROLLING ROOT-KNOT NEMATODE DTSEASE OF PEANUT (Meloidogyne arenaria) BY DDVP-COVERING MEMBRANE AND SEVERAL NEMATICIDE

DDVP-盖膜防治花生根结线虫病效果显著,为80％DDVP乳油每亩用量150～300g均有效,防治效果为100％,并能增产20～30％左右,对增加花生根瘤数效果也很明显,和对照相比增加14.36％～57.3％,其他杀线虫剂防治也有效,但增产效果不显著。

The effect of controlling root-knot nematode disease of peanut (Meloidogyne arenaria) by DDVP-covering membrane was 100％, increasing the yield of peanut by 20-30％ more than check and the number of root tubercle on main root of peanut by 14.36-57.23％more than check. Other methods were also effective.
