The damage caused by the indiscriminate use and incorrect use of pesticides, the appearance of pathogens resistance to fungicides and eco-consciousness, has motivated the development of methods and alternative products for controlling plant diseases, where essential oils have been recognized as an option. Downy mildew, caused by Plasmopara viticola, is an important grapevine disease. So, continuing the results already obtained and to contribute to the elaboration a program for management vine disease, with low environmental impact, is being proposed this study. Seven essential oils were selected based on information obtained in previous results. This study aims to evaluate in the laboratory and greenhouse, the feasibility and efficiency of essential oils of cinnamon, eucalyptus globulus, marjoram, melaleuca, peppermint piperita, oregano and white thyme in the management of downy mildew, by the following aspects: to determine, under laboratory conditions, the most suitable substrate to evaluate the of P. viticola spores germination; to evaluate, in laboratory, if there is fungicidal or fungistatic effects of essential oils on P. viticola; to determine, under greenhouse condition, the persistence of antifungal activity against P. viticola; to determine, under greenhouse condition, the essential oils rain resistance; to determine, under greenhouse condition, the curative and / or preventive effects of essential oils on the vine mildew; to evaluate possible phytotoxicity symptoms of essential oils in plants vine. With these results it is expected to find new products that can be evaluated in the field, in a next step, that can be recommended, on the future, to be used by the producer.
