Abstract
In organic farming, microbiological preparations are an alternative to chemical pesticides and mineral fertilizers. The article summarizes the experience of a three-year use of the biofungicide Extrasol in combination with colloidal sulfur in the vineyards of the Crimea. The use of the biofungicides makes it possible to control the development of powdery mildew of grape at the level of chemical plant protection products, including during the years of epiphytoties: on the cv. Bastardo magarachskiy grapes – 7.1–14.7 %, on the Italy grape cultivar – up to 5.2%. The degree of influence of the biofungicide Extrasol on the phenolic and oxidase complex of grapes depends on the background level of development of Uncinula necator and the biological effectiveness of the treatment. In comparison with chemical means of protection, the smallest effect of processing cv. Bastardo magarachskiy grapes with a biological product in relation to the accumulation of phenolic compounds was observed at a level of powdery mildew development of 30-50 %; the maximum increase in the technological reserve of phenolic compounds was 59 %, anthocyanins – 12 %; the activity of polyphenol oxidase increased 1.1–3.3 times. The use of the biofungicide Extrasol on Italian grape cultivar led to an increase in the weight of the bunch by an average of 11 %, yield – by 25.6 %, titratable acids – by 9.6 % relative to chemicals; improved the aroma, taste and texture of the berry.
