Resumo: | The control of the disease by plant extracts is a financially and ecologically feasible alternative for tomato small holders in Amazonas. Extracts and fractions of P. sprucei, C. cajucara, P. marginatum and C. zedoaria were evaluated in vitro and in vivo on tomato plants against the pathogen C. Cassiicola pathogen. The aqueous plant extracts at concentrations of 0%, 10%, 20%, 30%, 40% and 50%, and the effect of the hexanic, ethyl acetate and methanolic fractions, were evaluated on mycelial growth, sporulation and conidium germination of the fungus. Direct bioautography was performed and the minimum inhibitory concentration (MIC) and minimum fungicidal concentration (MFC) were determined. Aqueous extracts of P. marginatum were used to evaluate the reduction of disease symptoms in tomato seedlings. The hexane and ethyl acetate fractions of P. marginatum reduced mycelial growth, spore formation and conidium germination. In direct bioautography, zones of mycelial growth inhibition were observed in the hexane and ethyl acetate fractions of P. marginatum, with MIC of 2.5 mg mL-1. P. marginatum extract reduced disease severity in tomato seedlings, but was not effective in controlling the pathogen as a single management procedure. |

Extratos e frações de P. sprucei, C. cajucara, P. marginatum e C. zedoaria, foram avaliados in vitro e in vivo em tomateiro, contra o patógeno C. Cassiicola. Os extratos vegetais aquosos nas concentrações de 0%, 10%, 20%, 30%, 40% e 50%, e o efeito das frações hexânica, acetato de etila e metanólica, foram avaliados sobre o crescimento micelial, esporulação e germinação de conídios do fungo. A bioautografia direta foi realizada e as concentrações inibitória mínima (CIM) e fungicida mínima (CFM) foram determinadas. Extratos aquosos de P. marginatum foram usados para avaliar a redução dos sintomas da doença em mudas de tomateiro. As frações de hexano e acetato de etila de P. marginatum reduziram o crescimento micelial, formação de esporos e germinação de conídio. Na bioautografia direta, zonas de inibição do crescimento micelial foram observadas nas frações hexano e acetato de etila de P. marginatum, com CIM de 2,5 mg mL-1. O extrato P. marginatum reduziu a severidade da doença em mudas de tomate, mas não foi eficaz no controle do patógeno como procedimento de manejo único.Universidade Federal Rural da Amazônia/UFRA2023-12-20info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersiontextoinfo:eu-repo/semantics/otherapplication/pdfhttps://ajaes.ufra.edu.br/index.php/ajaes/article/view/3551Amazonian Journal of Agricultural Sciences Journal of Agricultural and Environmental Sciences; Vol 66 (2023): RCA AJAES; 1-13Revista de Ciências Agrárias Amazonian Journal of Agricultural and Environmental Sciences; v. 66 (2023): RCA AJAES; 1-132177-87601517-591Xreponame:Revista de Ciências Agrárias (Belém.
