Abstract
This study aimed i) to quantify the occurrence of Fusarium spp. and Trichoderma spp. in rhizospheric soil, with and without symptoms of Sudden Death Syndrome (SDS) in eight soybean genotypes; ii) morphologically identify isolates of Fusarium spp. from roots with SDS; iii) evaluate the antagonism between Trichoderma spp. and Fusarium spp. isolates from rhizospheric soil and roots from with and without SDS, respectively; and iv) characterize through the ITS1-5.8S-ITS2 region of rDNA the isolates of Trichoderma spp. with better performance in the direct confrontation. The sampling of soil and roots was performed in an experimental area located in Cruz Alta, RS, Bra...
