ABSTRACT

Pecan is susceptible to the occurrence of diseases capable of harming its development, and leaf
spot caused by Cladosporium spp is among them. Therefore, the objective of this work was to
analyze the potential antagonist and in vitro effect of volatile metabolites of Trichodermaspp.
On Cladosporium spp. isolated from pecan leaf spots. Three Cladosporium spp. isolates and two
commercial products based on Trichodermaspp. were used, as well as an isolate of the same
genus provided by the ‘ElocyMinussi’ Laboratory of Phytopathology at UFSM. Cladosporium spp.
mycelial growth was monitored in order to evaluate the morphological characteristics of the
pathogen. The use of Trichoderma spp. as biocontrol was assessed through dual culture tests
and production of volatile metabolites. Trichoderma spp. showed positive results in inhibiting
the growth of Cladosporium spp., thereby presenting potential to be used as a biocontrol agent.

Keywords: biological control, dual culture tests, antibiosis, biocontrol agents.
