瓜类白粉病的生物防治研究进展

Advances in Bio-Control of Cucurbits Powdery Mildew

白粉病是危害瓜类作物最为严重的一种气传病害,引起该病的病原菌为单囊壳白粉菌Podosphaera xanthii(synonym Podosphaera fusca)和二孢白粉菌Golovinomyces cichoracearum(synonym Erysiphe cichoracearum),其中对Podosphaera xanthii的报道较为常见。主要概述了瓜类白粉病病原菌的分类地位、病理特征和生物防治方面的研究进展,重点阐述了微生物源生防制剂和植物源生防制剂对瓜类白粉病的防治成果,并对当前研究与应用中存在的问题进行了探讨,为该病的深入研究和有效防治提供参考。

Powdery mildew is the most serious air-borne disease that spoils cucurbitaceous crops. The causes of the disease were Podosphaera xanthii（ synonym Podosphaera fusca） and Golovinomyces cichoracearum（ synonym Erysiphe cichoracearum）,of both P. xanthii is more commonly reported. Advances in the taxonomic status,pathological features,and biocontrol of cucurbits powdery pathogens were summarized in this paper. The key points is to elaborate the research achievements of bio-control with microbial and botanical resources against cucurbits powdery. The present existing problems in current studies and application were also discussed,providing references for the further research and effective control of this disease.
