This study was carried out to evaluate the in vitro antifungal potential of natural extracts from marc, spontaneous flora plants, and synthetic pesticides. The biological control of pathogens is a modern alternative because does not represent a danger to humans and the environment. Thus, natural alternatives with a fungistatic or fungicidal effect on the pathogen Botrytis cinerea were identified. The results of the in vitro tests clearly indicated a significant inhibitory percentage on the growth rate of the Botrytis cinerea rot mycelium (62.38%), when was used the extract obtained from the Cabernet Sauvignon marc at a concentration of 15%, compared to the other two natural extracts used (Salvia officinalis and Chelidonium majus), where the diameter of the colonies recorded values close to the untreated control variant. Regarding the effect of the synthetic pesticides studied, the best results were recorded with fosetyl-aluminum where a 100% inhibition percentage on the Botrytis cinerea pathogen was recorded.
