The verrucose caused by Cladosporium herbarum reduces production and quality of Passion fruit (Passiflora edulis Sims.), a largely consumed tropical fruit. This work aimed to investigate the antagonism of Trichoderma species (T. polysporum, T. koningii, T. viride and T. harzianum) against Cladosporium herbarum, and to study the production of extracellular hydrolytic enzymes by the pathogen and the antagonists. The results showed considerable antagonistic potential for the biocontrol of C. herbarum isolates by all Trichoderma species, except T. koningii. The most distinguished effect was observed for T. polysporum. In relation to the pattern of esterase obtained by electrophoresis in poliacrylamyde gel, the major activity presented by the isolates was...
