Ethanolic extract of Copaifera, Croton and Lippia on the control of phytopathogenic fungi

ABSTRACT The search for vegetable extracts phytosanitary control has been expanded to find new active ingredients plant diseases. This study aimed evaluate the in vitro effect of fixed constituents Copaifera luetzelburgii, Croton zehntneri and Lippia lasiocalycina, at concentrations 2, 20, 200 2,000 μg mL-1, on percentage mycelial growth inhibition Colletotrichum siamense, C. truncatum, Fusarium sacchari, F. udum, Lasiodiplodia theobromae Thielaviopsis ethacetica, as well conidium concentration sacchari udum produced culture medium with all extracts. tested ethanolic extract, especially highest concentration, inhibited and/or evaluated fungi. other showed low inhibitory effects or no activity against average values extract from L. luetzelburgii six fungi were 62.5, 53.4 51.0 %, respectively. lasiocalycina most significant conidia concentration. mL-1 be efficient inhibiting T. inhibit production udum.
