ABSTRACT

A survey was conducted in Coimbatore district of Tamil Nadu to assess the incidence of Fusarium wilt disease in tomato growing areas. The maximum wilt disease incidence of 75.0% was recorded in Nachipalayam village of Coimbatore District. Pathogen was isolated and Fusarium wilt causing pathogen was identified as F. oxysporum f. sp. lycopersici. Pathogenicity of the primarily isolated fungi was proved by showing external symptoms (wilting and yellowing leaves) while transplanting the tomato seeding into pathogen inoculated pots.
