Pathogen Identification and Two Inoculation Method of Fusarium Crown and Root Rot
摘要
Abstract
In order to identify the pathogenic fungi which causing tomato bacterial wilt in Fengnan District of Hebei Province. This study proved the disease as Bipolaris sorokiniana by pathogen isolation,pathogenicity test,mor-phological observation,and rDNA-ITS gene sequence analyses was caused by Fusarium oxysporum f. sp. radicis-lyco-persici( Forl) . The result showed that the mortality and morbidity of stem based inoculation were higher than root soaking inoculation. So,the disease with stem based inoculation developed faster. The study provided theoretical ba-sis for the breeding of disease resistance and the screening of the fungicides.关键词
