In order to keep pathogen damage to an acceptable level, pesticide application is needed, but abusive pesticide use may lead to negative changes in the biological balance by the presence of toxic residues. In the orchard experiments, the effect of conventional and unconventional treatments applied to vegetation in the control of the main pathogens of the apple. Five varieties were used: Granny Smith, Topaz, Imperial Gala, Jonagold, and Golden Reinders. Due to the large harvest losses, both quantitative and qualitative, Venturia inequalis is considered one of the most dangerous pathogen of apples trees. Along with Venturia inaequalis, Monilinia fructigena is a pathogen that can occur frequently in apple plantations. The diseases produced by this two pathogens occur during the growing season and the storage period. The degree of attack by Venturia inaequalis on leaves varied between 0.003% in the variant treated with methyl thiophanate and 13.75% in the untreated control variant. At fruit level, the attack rate was lower (between 0.043 and 10.25%). The attack of Monilinia fructigena was the lowest, not exceeding 1% in treated variants. This study reveals the effectiveness of the most used fungicides, especially those usable in organic farming.
