The apple scab disease which is caused by the fungus of Venturia inaequalis is a continuous problem to the applegrowers. The infection requires immediate and continuous treatment in order to control the disease. Nowdays there are several fungicides for treatment of apple scab with different application time. The objective of this study was to identify the optimal action threshold and combining it with some treatment programs for managing the scab disease. For this reason eight treatment programs were created consisting with several fungicides and were realized in three different treatment periods within same year. This research is conducted in one experimental orchard from 2015 to 2017. The disease infection levels were checked on 2400 leaves from 98 apple trees. Based on analyzed disease index the treatment times and variants were compared with each other to results with the best combination of chemicals and application time frame for disease management.
