RAMIREZ GONZALEZ, Sandra Isabel; LOPEZ BAEZ, Orlando; ESPINOSA ZARAGOZA, Saúl  e  WONG VILLARREAL, Arnoldo. Antifungal activity of hidrodestillates and oils on Alternaria solani, Fusarium oxysporum and Colletotrichum gloeosporioides. Rev. Mex. Cienc. Agríc [online]. 2016, vol.7, n.8, pp.1879-1891. ISSN 2007-0934.

Tomato and papaya are crops of great economic importance to producers from Chiapas; however, they are experiencing a production crisis due to limited options for alternative management of its major diseases. In this study, were assessed in vitro the regulatory effect hidrodestillates and Cinnamomum zeylanicum, Syzygium aromaticum and Pimienta dioica oils (obtained by traditional distillation and microwave assisted) on Alternaria solani, Fusarium oxysporum isolated from Lycopersicon esculentum and on Colletotrichum gloeosporioides isolated from Carica papaya. Poisoned medium technique was used in a first trial a concentration of hidrodistillate at 30% (v/v) and 1% for oils were used. Then the minimum inhibitory concentration was determined. The regulatory effect was determined by quantifying mycelial growth and conidia formation. The results indicated that clove hidrodistllate completely inhibited A. solani and F. oxysporum at 30% and 10% to C. gloeosporioides, while cinnamon microwaveassisted inhibited A. solani and C. gloeosporioides 10% and 30% to F. oxysporum, and clove at 30% inhibits F. oxysporum and A. solani and at 10% C. gloeosporioides and cinnamon and clove oils at 0.05% inhibited A. solani and C. gloesporioides. It is concluded that hidrodestillates and oils from C. zeylanicum, Z. aromaticum and P. dioica obtained by microwave are more efficient in inhibiting the growth of these pathogens than by traditional distillation, which can be an alternative for its management.
