Sweet and sour cherries are fruit with great potential in the agroecological conditions of Serbia, taking into account its climatic and geographical conditions. In the production of these plant species, a number of leaf pathogens may occur. One of the most significant is Blumeriella jaapii occurring mainly on commercial cultivars present in Serbia. The occurrence and development of this pathogen mostly depends on climatic conditions. Under favorable climatic conditions, infection progressively develops through the season and causes premature defoliation resulting in decreased fruit quality and increased bud sensitivity to frost, reduced yield and fruit size, as well as tree die-back the following season. In addition to chemical control, agrotechnical and other measures must be employed. Several active ingredients are registered against cherry leaf spot in Serbia: mancozeb, dodine, prochloraz, dithianon, and the mixture of primary and secondary potassium phosphate+chlorothalonil. There are eight registered products based on the above-mentioned active ingredients. The risk of resistance development to fungicides registered against B. jaapii in Serbia is low. Nonetheless, implementation of resistance management strategy is proposed.
