头病害调查和综合防治研究

Integrated Management and Investigation of Scallion Diseases in Jiangxi Province

经１９９２～１９９５年调查，江西有头病害１５种，其中以炭疽病、叶枯病发生面积大，损失重；对炭疽病和叶枯病的发病规律及主要发病因素进行了系统观察研究。以此两种病害为重点防治对象，兼顾其他叶部病害及地下部病害，结合头生育规律，提出综合防治策略和措施，为江西头病害的防治提供了理论依据。

Through investigation between 1992～1995, there are 15 scallion (Allium chinense G. Don) diseases in Jiangxi province. Of them,scallion anthracnose and scallion leaf wilt took place in large areas and seriously led scallion loss. The occurrence and integral management methods of the two diseases were studied systematically.They can be effectively controlled, and management methods of other scallion diseases were proposed in this paper.
