Description O uso de compostos vegetais como alternativa para controle de fitopatógenos tem recebido destaque em pesquisas que visam viabilizar métodos de manejo sustentável na agricultura. Fungos como Didymella bryoniae, Pyricularia grisea, Rhizoctonia solani e Sclerotium rolfsii são importantes por causarem grandes perdas na produção. Neste contexto, objetivou-se avaliar a fungitoxicidade de óleos vegetais na inibição do crescimento de fungos fitopatogênicos. Os ensaios foram conduzidos em delineamento inteiramente casualizado com 13 tratamentos (Cymbopogon nardus, C. citratus, Lippia alba, Eugenia dysenterica, Caryocar brasiliense, Azadirachta indica, A. indica - comercial, Ageratum conyzoides, Jatropha curcas, Eucalyptus sp., Mentha piperita, Tiofanato metílico e Testemunha) e quatro repetições. Para a avaliação da fungitoxicidade, foram distribuídos 1,5μ L mL-1 dos tratamentos na superfície do meio de cultura BDA (batata-dextrose-ágar). Os óleos essenciais de Eucalyptus sp., M. piperita, L. alba, C. nardus e C. citratus inibiram o crescimento de P. grisea. D. bryoniae não apresentou crescimento micelial apenas no óleo de C. citratus. Os fungos R. solani e S. rolfsii não cresceram quando submetidos aos tratamentos de óleos essenciais de M. piperita, L. alba, C. nardus e C. citratus.
The use of vegetable compounds as an alternative for control phytopathogens has received prominence in research to enable sustainable management methods in agriculture. Fungi such as Didymella bryoniae, Pyricularia grisea, Rhizoctonia solani, and Sclerotium rolfsii are important for causing great losses in production. In this context, the purpose was to evaluate the fungitoxicity of plant oils in inhibiting themycelial growth of pathogenic fungi. The tests were conducted in completely randomized design with 13 treatments (Cymbopogon nardus, C. citratus, Lippia alba, Eugenia dysenterica, Caryocar brasiliense, Azadirachta indica, A. indica – commercial – Ageratumconyzoides, Jatropha curcas, Eucalyptus sp., Mentha piperita, Tiofanato metílico e Testemunha) and four replications. To evaluate the fungitoxicity were distributed, 1.5 μ L mL-1 of the treatment were distributed on the surface of PDA culture medium. The Eucalyptus sp., M. piperita, L. alba, C. nardus, and C. citratus essential oils inhibited the growth of the fungus P. grisea. D. bryoniae did not growth only in the treatment of C. citratus. The R. solani and S. rolfsii fungi did not show mycelial growth when subjected to treatments of M. piperita, L. alba, C. nardus, and C. citrates essential oils.
