One of the alternatives to reduce the use of pesticides may be the use of essential oils to control diseases and pests that affect agricultural production. The purpose of this study was to evaluate the fungicide effect of essential oils of Schinus molle L. and Schinus terebinthifoliusRaddi, native species widely distributed in the region. The oils were extracted by hydro distillation and analyzed by gas chromatography. The phytopathogenic fungi Alternariaspp., Botrytisspp., Colletotrichumspp. and Fusarium spp., were isolated from "gerberas" and roses with symptoms of disease and antifungal activity of the tests were carried out by the technique of spreading disk. The data was analyzed by Tukey and Duncan tests to 5%. In general, the essential oil of S. mollewas effective for the four fungi tested, for the four dilutions used and for all the times evaluated. The essential oil of S. terebinthifolius presents more pronounced fungicide effect against Botrytisspp., from in vitro tests.
