Abstract:
Trichoderma spp., is a highly efficient antagonist of root pathogens, such as Rhizoctonia solani, which causes loss in many crops. The aim of this research was to evaluate in vitro the antagonistic capacity of T. viride, T. koningii, T. harzianum and Trichoderma spp. isolates against R. solani from a potato crop. In confrontation tests, all Trichoderma isolates were classified as antagonists class 2 according to Bell scale, where T. harzianum and T. koningii showed more than 60% inhibition of the radial growth of R. solani at 120 h. In the interaction between T. harzianum and Trichoderma spp. with R. solani, as mycoparasitism strategy, vacuolization, lysis, coiling, and penetration were demonstrated, the last two were present in all Trichoderma isolates evaluated.
