In unstable environmental conditions, research on replacing pesticides with high consumption rates with modern ones with lower consumption rates, determining their effect on productivity and biometric indicators of a culture is relevant. The goal of the research was to evaluate the use of fungicides of inorganic copper compounds as the main xenobiotics in apple and plum agroecosystems in the Krasnodar Territory and development elements of energy-saving protection technologies for changing weather conditions that ensure maximum efficiency with minimal ecotoxicity. The studies were carried out in 2018-2020. In extreme weather conditions, the preparations Champ DP, WDG and Kocide 2000, WDG showed the effectiveness of apple scab control at the level of 96.8- ± 0.6%. Fungicides Cuproxat, SC and Terpen C, SC in the control of Klyasterosporioz plum - at the level of 92.2-99.0%. Fungicides of the copper group had a negative effect on apple and plum plants: a decrease in the length of annual shoots and leaf area was noted. The use of Terpen C, SC, containing terpene stimuli, stimulated the growth of one-year plum shoots by 27.7% and an increase in the leaf area by 11.6%, in comparison with the control. The content of copper in the fruits of apple and plum trees and in the soil under their plantations was in accordance with the requirements not exceeding hygienic standards. The results obtained can be used to develop elements of energy-saving technologies for protecting apple and plum trees in a changing climate.
