Investigation of Main Fungal Diseases of Pepper(Piper nigrum L.nn) in Hainan Province and Its Pathogen Identification

[目的]明确当前海南胡椒主要真菌病害及对应病原菌种类。[方法]对海南13个胡椒主要种植区域的胡椒园进行系统调查,对所得标本进行病原菌分离、鉴定。[结果]共调查到真菌病害7种,分别为胡椒瘟病、炭疽病、枯萎病、慢蔫病、根腐病、基腐病、菌核病。目前,危害胡椒最严重的为胡椒瘟病、胡椒炭疽病、慢蔫病和枯萎病。[结论]研究结果为胡椒病害的综合防治和科研工作者掌握其最新动态提供了理论依据。

[Objective] The paper was to confirm the current major diseases of pepper in Hainan Province and their corresponding pathogens.[Method]The pepper gardens in the main cultivation regions of 13 species of pepper in Hainan Province were systematically investigated,and the pathogens of the obtained specimens were isolated and identified.[Result]Seven fungal diseases in pepper were totally investigated,including blast,anthracnose,blight,slow wilt,root rot,basal rot and Sclerotinia.Currently,the diseases with the serious damage on pepper include blast,anthracnose,blight and slow wilt.[Conclusion]The result provides the theoretical basis for the integrated control of diseases in pepper,and is also benefit for scientific research workers to master the latest dynamic of diseases.
