Abstract: To produce a stable and high yield of high-quality apple fruit, it is important to form optimal protection and nutrition systems. This work aims to study the impact of plant protection products in tank mixtures with fertilizers on scab development inhibition, fruit quality, and productivity. The research was conducted in 2020-2021 at JSC Dubovoe on the ‘Bogatyr’ cultivar. The degree of scab development on leaves and fruit, biological efficiency, yield per tree, and the content of nitrogen, phosphorus, potassium, calcium, magnesium, copper, zinc, manganese, and molybdenum in the leaves were determined. In the variant when protection products and foliar fertilizers were used in one tank mixture,a decrease in scab development and an increase in biological efficiency were observed. In this variant, the scab index ranged from 0.2 to 2.5 % for leaves and from 0.1 to 0.5 % for fruit. Biological efficiency reached 90.7 % for leaves and 97.9 % for fruit. The application of fertilizers in the variant with an experimental protection system ensured the maximum yield (39 and 48 kg/tree) and the highest proportion of first-grade fruit (86 and 92 %). The use of foliar fertilizers optimized the content of macro- and microelements in the leaves, which increased the effectiveness of plant protection agents.
