过去,水稻白叶枯病病菌在东南亚各国和中国,作为病菌的越冬传染源,除了水稻以外,几乎未提到有其它的寄主植物。可是近年来用噬菌体的方法证明,病菌可以在寄主杂草的根际和地下茎上越冬。一、从各种植物上检查病菌的方法检查白叶枯病菌一般都采用噬菌体测定法。本文采用菌泥喷出法(简称B、E法)来 In the past, bacterial leaf blight in Southeast Asian countries and China as a source of overwintering infection of germs, with the exception of rice, almost no mention of other host plants. In recent years, however, phage methods have proved that the bacteria can overwinter in the rhizosphere and underground stems of host weeds. First, check the pathogen from a variety of plant methods to check bacterial leaf blight generally use phage assay. In this paper, bacteria spray method (referred to as B, E method) to
