Conteúdo: | Filtrates of three fungi causing vascular wilting (Deuterophoma tracheiphila, Fusarium oxysporum f. lycopersici and Verticillium alboatrum) showed inhibitor activity on the appearance of local and systemic lesions in leaves of Vigna sinensis experimentally inoculated with Citrus infectious variegation virus (CVV). With regard to the filtrate obtained from D. tracheiphila cultures, it is observed that: 1) the inhibitor  activity increases with the age the culture; 2) the time of contact of a mixture of virus and fungus filtrate at 21grausC during 4 hr does not influence the degree of infectivity; 3) th inhibitor activity reveals when applied until 2 days before and 1 hr after inoculation with virus; 4) the inhibitor activity is lower in Tobacco plants inoculated with TMV and does not reveal in Bean plants inoculated with CVV. 5) in leaves treated with the filtrate and inoculated with CVV, even in total absence of lesions, an increase of polyphenoloxidase activity  like that observed in leaves only inoculated and where lesions regularly appreared, accurred.
