This study aimed to identify four isolates of Trichoderma sp. (Ufra.T06, Ufra.T09, Ufra.T12, and Ufra.T52) and characterize their interaction with Magnaporthe oryzae in vitro and in vivo conditions. The four isolates of Trichoderma sp. were sequenced, investigated as an antagonist against M. oryzae in five Petri plate assays, and as an inhibitor of conidial germination appressoria formation. Finally, were quantified the lytic activity of chitinase (CHI), glucanase (GLU), and protease (PRO) during co-cultivation of Trichoderma sp. and M. oryzae. In vivo, leaf blast suppression was evaluated intwo assays: simultaneous and curative application. Both in vitro and in vivo assays were scanned by electron microscopy (SEM). All isolates were identified as Trichoderma asperellum. All in vitro Petri plates assays reduced M. oryzae colony growth (paired?91.18% by Ufra.T09, volatile metabolites?all isolates equally reduced, non-volatile?68.33% by Ufra.T06,thermostability?99.77% by Ufra.T52 and co-cultivate?64.25% by Ufra.T52). The filtrates and conidia suspensions for T. asperellum isolates inhibited the conidia germination and appressoria formation significantly. In co-cultivate (mycelial or cell wall), all enzymes (GLU, CHI, and PRO) and times (24, 48, and 72 h) showed increased activity. In vivo, reduced leafblast severity until 94.64% (Ufra.T52cs) in a simultaneous and until 85% (Ufra.T09 24 and 48 hasi) in a curative application. T. asperellum isolates showed efficient control of M. oryzae by mycoparasitism, and antibiosis mechanisms were interfered with by the M. oryzae infection process.

O objetivo desse trabalho foi avaliar os atributos microbiológicos do solo em dois solos (artificialmente e naturalmente infestados com Ralstonia solanacearum) cultivado com tomate Solanum lycopersicum cv. San Vito, e fertilizado com três diferentes bokashis (da Embrapa Hortaliças-BE, de cama de aviário-BA e de esterco de gado-BG). Foi avaliado nesse trabalho os teores de Carbono da Biomassa Microbiana (CBM), Carbono Orgânico Total, Respiração basal (RB), coeficiente metabólico (qCO2) e coeficiente microbiano (qMIC). |
