Abstract

The phytopathogen Sclerotinia sclerotiorum, which causes the disease known as white mold, affects several agro crops worldwide, its high degree of pathogenicity is associated with the formation of sclerotia that acts as a resistance and survival mechanism. Considering the need for methods that contribute to agricultural development without causing damage to the environment and the population, biological control agents are now seen as excellent artifice. Fungi of the genus Trichoderma are considered astute biocontrol agents because they have numerous mechanisms with high antagonistic potential that impair spore germination, hyphal growth, and the development of sclerotia and chlamydospores of various phytopathogens. Seeking to evaluate the efficiency of Trichoderma spp. from areas of the Cerrado of Tocantins in the biocontrol of the phytopathogen S. sclerotiorum, pairing, enzymatic and secondary metabolite production tests were carried out. Through the obtained results it was possible to conclude that the isolate Trichoderma spp. 2, from areas of the Cerrado of Tocantins, has the potential to be considered as a bio controller for the phytopathogen S. Sclerotiorum, its antagonism being more evident through the production of volatile secondary metabolites.
