The effectiveness of inorganic copper compounds on apple and plum trees under extreme weather conditions in 2018-2020 has been evaluated. Fungicides Koside 2000, VDG and Champ DP, VDG controlled apple scab by 98-99.6%, preparations Cuproxat, KS and Terpen C, KS blocked plum clotterosporiasis by 85.1-100%. The use of these fungicides did not have a negative effect on the biochemical composition of the fruit. Significant differences between the variants were found in the content of potassium and calcium cations, on the drain, in addition, in the content of sodium and magnesium cations. The possibility of biologization of protection technologies has been established: the use of the fungicide Champ DP, VDG on the apple tree, the replacement of Abiga-Peak, VS on the drain with preparations with lower consumption rates – Kuproksat, KS and Terpen C, KS. This ensures a reduction in the pesticide load on the environment, a decrease in the risk of resistance and the damaging effect of fungicides on trees weakened by stress.
