Antifungal activity of chili pepper extract with potential for the control of some major pathogens in grapevine.

The results suggested a potentiality of chili pepper extract for the control of some important grapevine pathogens, their possible application being helpful for the recommended limitation in extensive use of copper in vineyard. The complex mixture of high amounts of capsaicinoids, associated to specific phenolic acids and other minor bioactive components might contribute for the observed antimicrobial action of chili pepper extract.
