四个内生菌菌株防治西瓜枯萎病初报

A Preliminary Report on Controlling Watermelon Fusarium Wilt with Four Endophytes

对从珠海市农业科学研究中心引进的R14、R21、S11和Ha8 4个内生菌菌株开展了室内抑制西瓜枯萎病菌菌丝生长和田间防病效果的试验。结果表明:R14、R21和S11菌株的室内抑菌率均在80%以上;首次用Ha8菌株发酵液灌根,第2、3、4次分别用R14和S11菌株发酵液灌根的田间防治效果达60%以上。

The inhibition effects of pathogen mycelium of watermelon Fusarium wilt in indoor and field control effect were tested by using endophyte R14, R21, Slland Ha8 introduced from Zhuhai Agriculture Research Center. The result showed that the inhibitory rate of endophyte R14, R21 and S11 to the fungus of watermelon Fusarium wilt in indoor were over 80 % ; The control effect of watermelon Fusarium wilt in field were over 60 % , firstly by pouring endophyte Ha8 fermentation broth to root, and then by pouring endophyte R14 and S11 fermentative liquid to root for the second, third and fourth times.
