Occurence of stem and root rot of cucumber in field and Polyhouse conditions in Udaipur region: survey, collection, identification and proveing the pathogenicity of pathogen

Abstract

Root and stem rot of cucumber is believed to be caused by a new formae specialis of F. oxyspowm, presently designated F. oxysporum f. sp. radicis - cucumerinum (FORC) (Vakalounakis, 1996). Fusarium root and stem rot is one of the most damaging diseases of cucumber. This is the most destructive disease of glasshouse cucumber crops in Canada in 1994, in France in 1998, in China in 1999, and in Spain in 2000, causing significant losses in the yield (Punja & Parker, 2000). The present investigation was therefore, undertaken with the Occurrence, identification and pathogenicity of Fusarium oxysporum f. sp. radicis cucumerinum causing root and stem rot of cucumber in polyhouse and field conditions under Udaipur region.
