Identification and pathogenicity of Fusarium spp. associated with tuber dry rot and wilt of potato in Algeria

Abstract Fusarium is one of the most important genera phytopathogenic fungi, causing potato wilt in field and tuber dry rot during storage. The objectives this study were to identify species associated with both diseases different growing regions Algeria, assess their pathogenicity. Among 152 isolates collected from symptomatic plants tubers provinces 13 Neocosmospora identified. these three isolated only showing symptoms ( F. oxysporum , venenatum, solani ). Two culmorum, N. tonkinensis ) an isolate sp . found exclusively remaining ones redolens, cf. tricinctum, sambucinum, incarnatum-equiseti, nygamai, brachygibbosum falciformis sample types. sambucinum was frequent (52.6% isolates). nygamai aggressive pathogenicity test, test. This first identifying characterizing pathogens Algeria.
