The author presents the results of researching the efficiency of the biological preparations  Gaupsin and Triñhodermin in the system of the peach protection against leaf curl and clasterosporium. Their application against those diseases under the developed scheme proved moreeffective than in the standard variant – 4-fold application of the chemical preparations Bordo Izagro, 20 SC (5.0 kg/ha), Chorus, 75 WG (0.3 kg/ha), Delan, 70 WG (1 kg/ha), Topsin M, 70 SC (3.0 kg/ha) and was in average 79-89 and 65-69% for thecultivars Skazka and Redhaven respectively. However, the effectiveness of the studied biofungicides against clasterosporium was 1.1 and 1.4 times lower than against peach leaf curl.
