“…Plant remnants and their decay products are foodstuff for soil microorganisms (Mangenot & Diem 1979). As a result of three-year study of stem base and roots of tomato grown with field pea as a cover plant or without it (control plot), it was found that fungi from genus Fusarium were the most numerous group of fungi developing on stem base and roots of tomato.…”

SummaryNo-tillage method with various cover crops has become popular recently in vegetable production (Abdul-Baki et al. 1996). The aim of a study conducted in 1998-2000 was evaluation of the effect of field pea (Pisum arvense L.) as a cover crop on the health of roots and stem base of tomato cultivated in the field. The field pea decreased the number of Fusarium oxysporum and Rhizoctonia solani and increased the number of antagonistic fungi Trichoderma spp. and Penicillium spp. on the roots and stem base of tomato.The numerical classification method (Podani 1993, Łaska 2001) applied to compare fungal communities from the roots and stem base of tomato grown conventionally and in field with pea as cover crop showed that similarity coefficient ranged from 21% to 59%.

“…Humphris et al (9) estudando os efeitos de metabólitos secundários voláteis produzidos por Trichoderma pseudokoningii, T. viride e T. aureoviride sobre a taxa de crescimento de dois isolados de Serpula lacrymans, observaram que esta foi afetada dependendo da interação microbiana e indicaram envolvimento de especificidade nos testes. As atividades dos compostos voláteis produzidos por microrganismos decompositores também podem apresentar efeito bastante variado em diferentes espécies de fungos, inibindo ou estimulando o crescimento micelial de outros fungos (15). Microrganismos que produzam metabólitos voláteis podem ser utilizados em conjunto com outros métodos de controle (20).…”

Alternaria solani, agente etiológico da pinta preta, é considerado um fitopatógeno de grande impacto econômico na cultura do tomate, gerando grandes prejuízos aos agricultores. O objetivo deste trabalho foi verificar o potencial antagonista por confronto direto, produção de voláteis e atividade antimicrobiana in vitro de filtrado de fungos sapróbios contra A. ABSTRACTAlternaria solani, the etiological agent of early blight, is considered a phytopathogen of great economic impact on tomato crop, causing great losses to farmers. The aim of this study was to assess the antagonistic potential for direct confrontation, the production of volatile compounds and the in vitro antimicrobial activity of saprobic fungal filtrate against A. solani. Thus, the phytopathogen A. solani was confronted with the saprobic fungi Volutella minima, Memnoniella echinata, M. levispora, Curvularia eragrostidis, C. inaequalis, Gonytrichum chlamydosporium, G. macrocladum, Pseudobotrytis terrestris, Pithomyces chartarum, Lappodochium lageniforme, Dictyochaeta simplex, Stachybotrys nephrosfora and S. globosa, to observe inhibition zone formation and aggressiveness of the fungi according to a score scale. The phytopathogen growth was also evaluated at the concentration of 20% to select the saprobe filtrate with antimicrobial activity. Subsequently, the Solino, A.J.S.; Oliveira, J.B.S.; Schwan-Estrada, K.R.F.; Marianna Santos Rodrigues Alencar, Ribeiro, L.M. Antagonistic potential and in vitro control of Alternaria solani by saprobic fungi. Summa Phytopathologica, v.43, n.3, p.199-204, 2017. selected saprobe filtrates were studied at the concentrations of 5; 10; 15 and 20%, evaluating the mycelial growth of A. solani. The saprobes L. lageniforme and G. macrocladum showed greater mycelial growth, compared to A. solani, at seven days after transferring the phytopathogen. At 15 days, only L. lageniforme contained the pathogen. In the direct confrontation test, the fungi L. lageniforme and G. macrocladum occupied a larger area on the Petri dish, in contrast to the pathogen. The fungal filtrates G. macrocladum, C. inaequalis, P. terretris, S. globosa and C. eragrostidis, at a concentration of 20%, promoted a reduction in the mycelial growth of A. solani by 34, 21, 19, 10 and 10%, respectively. Analyzing the effect of the filtrate concentrations on the mycelial growth of A. solani, dose-dependence was observed in all treatments, with maximum growth inhibition for filtrates of G. macrocladum, C. inaequalis, P. terretris, S. globosa and C. eragrostidis, respectively, at the concentration of 20%.Keywords: biological control, antimicrobial activity, plant pathogen.Os cultivos agrícolas estão sujeitos a diversas doenças causadas por uma ampla gama de fitopatógenos (12).

“…The appreciation that fertilizers and pesticides may be toxic to people and the environment in general, was one important reason for stimulated interest in the exploitation of such interactions in agriculture and forestry -for example, the biological control of crop diseases (Mangenot & Diem 1979;Lynch 1983).…”
