“…The extracts of A. lappa, A. millefolium, Citrus sp., C. limon, C. longa, C. zedoarea, M. officinalis, O. biennis, O. gratissimum, P. alliacea, P. hysterophorus, P. major, R. graveolens and T. vulgaris were all active against C. gloeosporioides (Table 1), what is in accordance with the activity previously described against fungi from other genus (BENEVIDES et al, 2001;FICKER et al, 2003;FIORI et al, 2000;GIAMPERI et al, 2002;HOLETZ et al, 2002;KISHORE et al, 1996;MISHRA et al, 2002;NINO et al, 2003;POPOVIC et al, 2002;ROTH et al, 1998;SHRIVASTAVA et al, 1984;SHUKLA et al, 1999;SOUZA et al, 2005;TIWARI et al, 2003). Specifically for R. graveolens, the activity of the corresponding extract against C. gloesporioides was already known (OLIVA et al, 2003).…”

An unexpected result was obtained for the extracts of F. vulgare, G. hederaceae, M. glabra, M. spicata and M. oleifera, whose antifungal activity has already been described in the literature (ABOU-JAWDAH et al, 2002;ADAM et al, 1998;CACERES et al, 1993;CORTEZ et al, 1998;LIMA et al, 1992;PATRA et al, 2002).…”

Evaluation of the antifungal activity by plant extracts against Colletotrichum gloeosporioides Penz

et al. 2008

Aiming to develop more efficient and environmental friendly methods than those available to control Colletotrichum gloeosporioides Penz, which causes blister spot in coffee trees, a search for plants able to produce substances active against such pathogen was carried out. Thus, extracts of 48 plant species, collected at Alto Rio Grande region, in Minas Gerais, were prepared and submitted to in vitro assays with that fungus. The best results were obtained with the extracts prepared from Digitalis lanata Ehrh, Origanum manjorona L., Plantago lanceolata Hook. and Stevia rebaudiana (Bertoni) Bertoni, which inhibited C. gloeosporioides spores germination. After dilution of some active extracts with aqueous 1 % Tween 80 solution in a 1:2 or 1:3 ratio (extract:aqueous solution), their antifungal activity vanished. Some of the active extracts were also submitted to freeze drying and none of them presented any alteration in their antifungal activity. Concluding, several plants presented potential to be used in the search for new bioactive substances to control C. gloeosporioides, especially O. manjorona L., which inhibited 96 % of the fungus spores germination.Index terms: Disease control, biocide, Coffee s blister spot. RESUMOCom vistas a contribuir para o desenvolvimento de métodos mais eficientes e menos agressivos ao ambiente que aqueles disponíveis para o controle de Colletotrichum gloeosporioides Penz, causador da mancha manteigosa em cafeeiros, buscou-se identificar espécies vegetais produtoras de substâncias ativas contra o referido patógeno. Para tanto, prepararam-se extratos de 48 espécies vegetais, coletadas na região do Alto Rio Grande, em Minas Gerais, para serem submetidos a testes in vitro com o mencionado fungo. Constatou-se que os melhores resultados foram obtidos com os extratos oriundos de Digitalis lanata Ehrh, Origanum manjorona L., Plantago lanceolata Hook. e Stevia rebaudiana (Bertoni) Bertoni que inibiram a germinação dos esporos de C. gloeosporioides. Alguns dos extratos ativos também foram submetidos a diluições em solução aquosa de Tween 80 a 1%, o que permitiu observar que, na proporção de 1:2 ou 1:3 (extrato: solução aquosa), os extratos perdiam a atividade antifúngica. Verificouse também que alguns dos extratos ativos não alteraram suas atividades quando submetidos ao processo de liofilização. Desse modo, identificaram-se várias plantas promissoras na pesquisa por novas substâncias bioativas para o controle de C. gloeosporioides, com destaque para O. manjorona L., que inibiu 96% da germinação dos esporos do referido fungo.Termos para indexação: Controle de doenças, biocida, mancha manteigosa do cafeeiro.

Essential oils of Bunium persicum (Parsi Zira), Carum copticum (Ajwain) and Cinnamomum zeylanicum (cinnamon) were tested in vitro as growth inhibitors against six forma special of Fusarium oxysporum. Minimum inhibitory concentration (MIC) and median effective concentrations (EC 50 ) values (µl/L) were also demonstrated. The antifungal activity of essential oils was assayed by poison food medium method (0, 100, 200, 300, 400, and 500 µl/L). Essential oils were extracted by means of hydro-distillation and afterwards, gas chromatography-mass spectrometry (GC-MS) analysis was performed to identify their components. The main constituents were cinnamaldehyd (77.51%), β-linalool (11.13%), α-cubebene (1.18%) and 1S, CIS-calamenene (1.06%) for C. zeylanicum, thymol (52.95%), γ-terpinene (13.53%), p-cymene (11.28%) in C. copticum and γ-terpinene (24.02%), cuminaldehyde (20.1%), paracymene (13.09%), benzenemethanol alpha-propyl (13.01%), cyclopentane, 2-methyl-1-methylene-3-(1-methylethenyl) (3.57%) in B. persicum. All three essential oils exhibited antifungal effect on the studied fungi species; but essential oil of C. zeylanicum was more effective. The growth of F. oxysporum f. sp. lycopersici, F. oxysporum f. sp. ciceri and F. oxysporum f. sp. melonis was completely inhibited by essential oil of C. zeylanicum at 200 ppm concentrations.
