Viticulture is impossible without the use of chemical plant protection agents. Their use follows to ecological destabilization of ampelocenoses and constitutes real danger to human health. Last years there is a tendency to biologize the protection technologies that the relevance of studies of the influence of biopreparations on the quality of graps and wines. The article presents the results studies of fungicide action of the preparations Biocomposite-correct and Biocomposite-protect. Their high anti-mycotic activity (97-100%) against Trichothecium roseum and Botrytis cinerea has been established. The high efficiency in the control of grey rot on grapes cultivar Merlot showed a two-fold application of the Biocomposite-protect– the damage to grapes decreased by 2 times in comparison with the control and amounted to 0.3%. Using of biofungicides did not affect the of mush/must fermentation. The test wines were distinguished by a higher (by 13-28%) concentration of phenolic substances. The use of Biocomposite-protect followed to an increase of anthocyanins concentration (by 1.5 times) and the total dry extract (by 12%) in wines; decrease – of titratable acids; Biocomposite-correct – decrease the total dry extract (by 10%). Using of biological preparations for grape protection did not influence the organoleptic quality of wines.
