Abstract
Apple fruit cultivation is one of the most important cultivated fruit in the region of Gjilan in Kosovo and the cultivated areas are continuously increasing. There are 3-4 main cultivars Starking, Golden Delicious, Granny Smith, Gala that are being cultivated mostly and other cultivars Jonagold, Fuji and Jonathan that are being planted rapidly. One of the major problems for farmers in this region it remains the managing of fungus disease of Apple scab caused by Venturia inaequalis (Cooke) Wint.For this purpose, for the first time in Kosovo was used the decision support system RIM-pro (relative infection measure-program).This program simulates the development of pseudothecia, ascospore maturation, discharge, deposition and infection based on hourly received data of weather conditions and leaf wetness from weather station which is set up on the orchard. The aim of this study is to utilize the RIM-pro for best fungicide application time. The experiment is carried out in experimental orchard in Zhegra (Gjilan region) Kosovo, during the year 2015 and the experimental orchard was set up in randomized block, where the main effect factor is the treatment time (A) in 4 levels (RIM-pro time, Phenologicalphases, traditional treatment and control plants), second factor was the effectiveness of combined fungicides (B) in 4 levels. By analyzing the outcome data, it resulted that the treatments performed based on RIMpro had best results than other based performed treatments. The effectiveness of fungicides was determined by the disease index. This study emphasizes the importance of development of one management warning system for the local farmers.
