The Voineşti production basin is one of the most important fruit growing areas for apple crop. The load of pathogens in these plantations is very high due to climatic conditions and monoculture for a long period of time in the area. Venturia inaequalis is one of the main diseases affecting apple orchards. A major challenge in commercial apple orchards within humid production regions is the available fungicide options for apple scab (Venturia inaequalis (Cooke) Wint.) management. The objectives of this study were to compare the efficacy of five potential alternative fungicides for management of apple scab and to evaluate their effectiveness. Pest incidence, pest severity of the attack and yield of the Jonathan apple variety, one of the most sensitive in the area, were also analyzed by ARM software. The standard products Score 250 EC (0.225 l/ha) and Syllit 400 SC (2.0 l/ha) treatments resulted in the best scab control and consequently, high economic productivity.
