Resumo: Trichoderma is a biological control agent used to improve the resistance to diseases, which may also estimulate  plant growth. Commercial products with Trichoderma are available in different countries, but most of them are based on conidial suspension. This study aimed at evaluating the efficiency of native Trichoderma populations collected from different production systems and applied to the soil by using two methods: conidial suspension and inoculated oat grains. The efficiency of native Trichoderma populations collected from conventional crop and agropastoral and agrosilvopastoral systems in a long-term field experiment was evaluated. The populations efficiencies were evaluated by in vivo tests that assessed the control of soybean damping-off caused by Rhizoctonia solani, plant height and soil colonization with the antagonist. In vitro tests, such as dual culture and assessment of volatile and non-volatile compounds, were conducted to study the mode of action of the populations. Some native Trichoderma populations were as efficient as those from a commercial product in all tests. Compared to conidial suspension, Trichoderma spp. inoculated through oat grains promoted a greater damping-off control, higher plants and more colony-forming units per gram of soil after 3 months of application. Native populations performed equally well or even better than the commercial strain, and the use of a substrate that supports the Trichoderma growth was more efficient than the conidial suspension method.

Produtos comerciais com Trichoderma estão disponíveis em diversos países, mas a maioria baseia-se na suspensão de conídios. Objetivou-se avaliar a eficiência de populações nativas de Trichoderma coletadas de diferentes sistemas de produção e aplicadas ao solo por dois métodos: suspensão de conídios e grãos de aveia infestados. Avaliou-se a eficiência de populações de Trichoderma coletadas de lavoura convencional e sistemas agropastoril e agrossilvopastoril, em experimento de campo de longa duração. A eficiência foi avaliada por testes in vivo, analisando-se o controle de tombamento de soja causado por Rhizoctonia solani, a altura das plantas e a colonização do solo com o antagonista. Os testes in vitro de pareamento de culturas, compostos voláteis e não voláteis foram realizados para explicar o modo de ação das populações. Algumas populações de Trichoderma nativas foram tão eficientes quanto a obtida de produto comercial, em todos os testes. Com grãos de aveia infestados, Trichoderma spp. promoveu maior controle de tombamento, maior altura de plantas e mais unidades formadoras de colônias por grama de solo após três meses da aplicação, quando comparado com a suspensão de conídios. Populações nativas foram igualmente boas ou mesmo melhores do que a cepa comercial, e a utilização de um substrato que suporta o crescimento de Trichoderma foi mais eficiente do que a suspensão de conídios.Escola de Agronomia - Universidade Federal de Goiás2017-04-10info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionAvaliado por paresapplication/pdfhttps://revistas.ufg.br/pat/article/view/42966Pesquisa Agropecuária Tropical [Agricultural Research in the Tropics]; v. 47, n. 1, Jan./Mar. 2017; 102-109Pesquisa Agropecuária Tropical (Agricultural Research in the Tropics); v. 47, n. 1, jan./mar. 2017; 102-109Pesquisa Agropecuária Tropical; v. 47, n. 1, jan./mar. 2017; 102-1091983-4063reponame:Pesquisa Agropecuária Tropical (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGenghttps://revistas.ufg.br/pat/article/view/42966/22811Copyright (c) 2017 Pesquisa Agropecuária Tropical (Agricultural Research in the Tropics)info:eu-repo/semantics/openAccessRoese, Alexandre DinnysVidal, Gloria SorianoZielinski, Erica CamilaMay De Mio, Louise Larissa2020-07-13T18:30:33Zoai:ojs.revistas.ufg.br:article/42966Revistahttps://revistas.ufg.br/patPUBhttps://revistas.ufg.br/pat/oaiaseleguini.pat@gmail.com||mgoes@agro.ufg.br1983-40631517-6398opendoar:2024-05-21T19:56:15.243946Pesquisa Agropecuária Tropical (Online) - Universidade Federal de Goiás (UFG)true
