Abstract

The apple scab caused by the fungal pathogen Venturia inaequalis(Cooke) G. Winteris a continuous problem for apple farmers in Kosovo. From this disease, the fruits become scabby brown or black spotty, losing their value. The fruit infection from A. scab requires immediate and multi time treatment. In the agricultural market, there are several plant protection productsintegratedin to varioustreatment variantsprovided by chemical manufacturersto control the apple scab infections. The purposeof this study was to identify the bestaction threshold based onthe prediction of the infection riskprovided by one decision support system(DSS RIMpro) and based on the empirical point of view by selecting few fruit growth stages from BBCH scale to control thisdisease in the research zone. Therefore, two different treatment intervalswere used and eight treatment variantsconsisting of several fungicides were created. The research is carried outin one experimental orchard in cultivation with Starking apple cultivar. Based on analysed disease index on infected fruits, the treatment intervalswere compared with each other to conclude the best action thresholdfor Kosovo conditions.
