The use of fungicides for the control of pest in the vineyard
shows the risk of residues of these compounds in grapes, and their
transfer to wines elaborated with these grapes, implying a health
hazard. For this reason, their maximum residue limits (MRLs) are
controlled by the current legislation. Moreover, these residues
can affect the yeast involved in the fermentative process.
Hence, their effect on yeast population and fermentation have been
studied by several authors
