The aim of this study was to examine the impact of the implementation of remedial measures on the spread of PPV in infected plum orchards, as well as on the plum fruiting quantitative and qualitative parameters. The improvement measures have included the integral nutrition for plums with the application of metabolic and other types of fertilizers that stimulate endogenous plant resistance, and effective protection measures. The research was conducted in the period from 2006 to 2008, at six different locations in the areas of Konjic and Jablanica. The research targeed plum pox virus infected plantations of Požegača cultivar, aged 5-25 years. The selection, quantity and method of fertilizer application in these orchards were determined based on habitat characteristics, level of soil nutrients and the trees’ requirements. After the implementation of remedial measures in the samples taken from treated and untreated plots, the detection of plum pox virus was carried out, and quantitative and qualitative characteristics of the fruits were examined. Detection of viruses was performed by ELISA. Sugars were determined using the refractometer, acids by titration method, dry matter content by drying and fruit weight and total yield by weighing. The tests for viruses presence came back positive in all samples, however, the concentration of virus in treated trees was significantly lower. The parameters of the quantity and quality of plum were higher in treated plots.
