Appearance in Tunisia of Fusarium oxysporum f. sp. radicis-lycopersici, causing root and collar rot of tomato.

Abstract

In 2001, a serious attack was observed in glasshouse hydroponic tomatoes in southern Tunisia, affecting 16% of plants. F. oxysporum was isolated from the main root and collar. Its identity was checked on a set of differential cultivars, and the pathogen was found to be F. oxysporum f.sp. radicis-lycopersici, the cause of root and collar rot of tomato, detected in Tunisia for the first time.
