At the modern stage of development, the support of sustainable viticulture is possible having an optimal set of methods and means of effective disease control. Currently, with distribution and development of grape leaf alternariosis, the issue of forming a zonal assortment of fungicides by replenishing with preparations that effectively regulate the causative agent of this grape disease in addition to basic diseases - mildew and oidium, is updated. The paper presents the results of laboratory and field studies aimed at finding effective means of biological and chemical origin to control the development of grape alternariosis. The maximum antifungal activity against Alternaria sp. for the period of 2016-2020 in vitro was showen by 2 biological preparations based on OPS and OST-713 strains of the bacterium Bacillus amyloliquefaciens, as well as by active agents from triazole and strobilurin chemical classes. Field studies of 2018-2020 found out that the minimum values of aternariosis development on leaves were obtained with three-fold application of fungicides Skor, EC (0.4 l/ha), Acrobat Top, WDG (1.5 kg/ha), Dynali, DC (0.6 l/ha), Quadris, SC (0.6 l/ha), Topaz, EC (0.4 l/ha), as well as when using the biological preparation Serenade ASO, SC (5.0 l/ha). The obtained results allow to conclude that fungicides of both biological and chemical origin, intended for protection of grapes from basic diseases, can be used to effectively control grape alternariosis.
