The pathogens of spinach Globisporangium root rot
摘要
Abstract
Spinach root rot disease was found in five counties of Shandong Province.The roots of the diseased plants turn brown and become shorter,and the root epidermis turns wet rot and vascular bundles are necrotic;the lateral roots are significantly reduced,and the overground parts wilt and green-lose,and finally die in severe cases.Six oomycete strains were isolated and purified by the methods of tissue separation and glass capillary separation,respectively.According to morphological characteristics,biological characteristics,sequence analyses of ITS,cox1 and cox2 together with pathogenicity test by Koch's postulates,the pathogens were identified as Globisporangium irregulare and G.sylvaticum.This is the first report of spinach root rot caused by G.sylvaticum.关键词
