Control of pest and diseases in the production of sweet and sour cherry is essential to harvest a high percentage of useable fruits and preserve healthy trees. The diseases that commonly occur year after in sweet and sour cherry plantings are cherry leaf spot, and brown rot blossom blight. Major pests of commercial cherry orchards are cherry fruit fly, aphids and eryophide mites. Critical periods for pest and disease control need to be taken into account. Fungicide treatments should be applied in the petal fall stage to reduce leaf spot and continued at 7-14 day intervals depending on weather conditions. Cultural methods including fungicide treatments are essential for the control of Monilinia spp. in the cherry flowering stage and later during fruit ripening. A program for management of cherry fruit fly in the mid-late and late maturing cherry cultivars and Oblacinska sour cherry, is necessary in cherry plantings. Apart from spraying insecticides beginning of the ripening stage, novel preparations based on the fungus Beauveria bassiana are gaining in importance and present an acceptable solution from the toxicological and ecotoxicological standpoint.
