摘要
通过对水稻小粒翘穗病原的分离、鉴定、接种验证等一系列病理研究,确认了水稻干尖线虫是引起水稻小粒翘穗的病原。小粒翘穗为水稻干尖线虫病的一种非典型症状,病害的症状表现与水稻品种类型有关。用16%咪鲜.杀螟可湿性粉剂300倍液,浸种60h后催芽播种,可有效地防治该病害,防治效果为94.65%。
The pathogen of small grains and erect ears of rice was studied by using a series of pathological methods. The results showed that it was a new nontypical symptom caused by Aphelenchoides besseyi. Chemical seed treatment was the most effective control measure.
