Abstract: RESUMO Com o objetivo de avaliar in vitro o efeito de diferentes concentrações de extratos vegetais sobre o crescimento de Cercospora kikuchii. Fusarium solani. Colletotrichum sp. e Phomopsis sp., foram conduzidos quatro bioensaios experimentais, no Laboratório de Fitopatologia da Universidade Federal da Grande Dourados. Foi adotado o delineamento inteiramente casualizado em arranjo fatorial 3 x 6, com 8 repetições para cada bioensaio. Foram utilizados extratos aquosos de alho, canela e cravo-da-índia, nas con… Show more

“…and Penicillium chysogenum (Kumar et al 2009). This toxic effect was confirmed by cinnamon extract in results obtained by Venturoso et al (2011) when verifying that the dose of 20% reduced by 43% the mycelial growth of Phomopsis sp.…”

“…Antifungal activity on MG of F. solani had been reported for the crude aqueous extracts of the floral buds of clove (Syzygium aromaticum (L.) Merr. & L.M.Perry) (Venturoso et al 2011), and essential oil of thyme (Thymus vulgaris L.), which resulted in complete inhibition of mycelium development even at lower concentrations of the extracts (Krzyśko-Łupicka et al 2016).…”

“…The antifungal effect of lower concentrations of R. guttatus extract on M. phaseolina, as well as its effect on the promotion of MG in C. pseudometrosideri, may be related to the interaction among chemical constituents of the extract. An extract can present compounds that stimulate pathogen growth (Venturoso et al 2011). Thus, the relative amount of stimulating compounds and their half-lives, as well as the interaction between them, determines the action on the phytopathogen.…”

“…Devido à toxicidade, esses produtos podem contaminar o ambiente (Candido Silva et al, 2013), e elevar os custos de produção (Perina, 2014). Os efeitos negativos do uso indiscriminado de agrotóxicos tem incentivado a busca por métodos alternativos no manejo de doenças de culturas agrícolas e alguns estudos tem apresentado resultados promissores no controle de diversos fungos fitopatogênicos (Camatti-Sartori et al, 2011;Naruzawa et al, 2011;Venturoso et al, 2011a;Venturoso et al, 2011b).…”
