The investigations were made in the experimental sour cherry orchard from the Institute of Agriculture, Kyustendil, Bulgaria, during the period 2010-2014, in order to compare conventional and integrated sour cherry protection against cherry leaf spot and cherry fruit fly. Two variants were investigated, with two different treatment approaches for the control of cherry leaf spot and cherry fruit fly. Variant 1 – cherry leaf spot was controlled by protective treatments with dodin and tebuconazole + trifloxystrobin and cherry fruit fly was controlled by treatments with deltametrin and thiacloprid, independently of density. Variant 2 - cherry leaf spot was controlled by post-infection (curative) treatments with tebuconazole + trifloxystrobin and cherry fruit fly was controlled by treatments based on biological threshold: 10-11 cherry fruit fly females caught in traps up to the moment for chemical treatment. It was established that Blumeriella japii can be successfully controlled by post-infection treatments and by this the number of insecticide treatments was reduced. The treatments against cherry fruit fly can be avoided or reduced when the attack control is based on the biological threshold established in the studied area.
