FUNGICIDE PROPERTIES in Vitro OF CHITOSAN ETHYL CARBAMATE IN THE CONTROL OF VINEYARDS FUNGIES IN CHILE

ABSTRACT The grape table is the main fresh fruit export of Chile. However, is affected in the first place by fungal pathogens, resulting between 10 % and 15 % losses in production. The commercial use of biocides has a weakness generating an increase in demand for new antifungal agents. Chitosan and...
