Consequently, we searched for the presence of fungal antagonists for these pathogens, particularly Trichoderma. Seven species of Trichoderma inhabiting soils and crop residues were identified. Strains of all identified species had high in vitro antagonistic activity against both pathogens. These results confirm the presence of Trichoderma spp. naturally inhabiting crop residues and soils, with potential to inhibit C. sativus and P. tritici-repentis. Managing antagonist populations is a promising and underdeveloped strategy that warrant further investigation. © 2022 Informa UK Limited, trading as Taylor & Francis Group  aAntagonism  aBiological control  aCochliobolus sativus  aPyrenophora tritici-repentis  aTrichoderma1 aVERO, S.1 aPEREYRA, S.1 aALTIER, N.1 aDE LUCCA, F.1 aABREO, E.1 aPÉREZ, C.  tInternational Journal of Pest Management, 2022, vol. 68, issue 4: "Uruguayan Society of Phytopathology (SUFIT): Plant protection for a sustainable agriculture", p.359-368. doi: https://doi.org/10.1080/09670874.2022.2123568
