Resumo: The objective of this work was to evaluate the potential of Trichoderma isolates to control phytopathogenic fungi of forest importance. The tests were performed with Alternaria sp., Botrytis cinerea, Cylindrocladium candelabrum, Pestalotiopsis sp. and Sclerotium rolfsii. We used Trichoderma spp. collected from soils in Brunópolis, Rio do Sul and Curitibanos in Santa Catarina State, and in São Paulo, SP and from a commercial product (positive control). Pairing culture technique was carried out and evaluations were conducted out through daily measurements. The experimental design was completely randomized, with 5 replications. The area under the disease progress curve and the percentage of inhibition were calculated. The data were submitted to analysis of variance and Tukey’s test at 5% probability. In all treatments, mycelial growth differed from the absolute control, except for the fungus S. rolfsii where only the Curitibanos’ isolate showed inhibition. For the other pathogens, inhibition ranged from 46.8% to 75.5%. Regarding the diameter of the colonies, the inhibition varied from 56.2% to 87.0%. The isolates of the genus Trichoderma have high potential as inhibitors of some phytopathogens species.

Os testes foram realizados com os fungos patogênicos Alternaria sp., Botrytis cinerea, Cylindrocladium candelabrum, Pestalotiopsis sp. e Sclerotium rolfsii. Foram utilizados isolados de Trichoderma spp. coletados de solos em Brunópolis, Rio do Sul e Curitibanos, em Santa Catarina, e em São Paulo, SP e um isolado obtido de produto comercial (controle positivo). Foi realizado teste de pareamento em placas e as avaliações foram realizadas diariamente. O delineamento experimental foi inteiramente casualizado, com 5 repetições. Foi calculada a área abaixo da curva de crescimento micelial e a porcentagem de inibição. Os dados foram submetidos à análise de variância e ao teste de Tukey a 5% de probabilidade. Em todos os tratamentos, o crescimento micelial diferiu do controle, com exceção de S. rolfsii, onde apenas o isolado de Curitibanos, SC mostrou inibição. Para os outros patógenos, a inibição variou de 46,8% a 75,5%. Em relação ao diâmetro das colônias do último dia, a inibição foi de 56,2% a 87,0%. Os isolados do gênero Trichoderma apresentaram elevado potencial como inibidores para algumas espécies de fungos fitopatogênicosEmbrapa Florestas2023-07-07info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/octet-streamhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/214010.4336/2023.pfb.43e202002140cPesquisa Florestal Brasileira; v. 43 (2023)Pesquisa Florestal Brasileira; Vol. 43 (2023)1983-26051809-3647reponame:Pesquisa Florestal Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/2140/1677Copyright (c) 2023 Riani Grimes, Gabriela Carolina dos Santos, André Luiz Graf Júnior, João Batista Tolentino Júnior, Adriana Terumi Itakohttps://creativecommons.org/licenses/by-nc-nd/4.0info:eu-repo/semantics/openAccessGrimes, RianiSantos, Gabriela Carolina dosGraf Júnior, André LuizTolentino Júnior, João BatistaItako, Adriana Terumi2023-03-16T12:47:49Zoai:pfb.cnpf.embrapa.br/pfb:article/2140Revistahttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/PUBhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/oaipfb@embrapa.br || revista.pfb@gmail.com || patricia.mattos@embrapa.br1983-26051809-3647opendoar:2023-03-16T12:47:49Pesquisa Florestal Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
