| Abstract:
Since 1932, when Prof. D. Atanasov identified Sharka for the first time in Bulgaria, until today, the disease has spread in many regions of the country. During the 70s, the highly susceptible local cultivar ‘Kyustendilska’ was replaced by ‘Stanley’ and thus the plum production was temporarily restored. However, the utilization of a single plum cultivar in the orchards caused additional production and market problems. In connection with the epidemiological situation and the resulting heavy losses, researchers in recent years have increased their efforts to elaborate a strategy for controlling the Sharka damages in Bulgaria. This strategy includes the following key elements: introduction of certification scheme for the production of virus free planting material of plum; enrichment of the national list of plum cultivars by introduction of foreign cultivars and conduction of own breeding for Sharka-resistant and tolerant cultivars; developing of new intensive technologies for plum production that will ensure control of Sharka spreading and provide quick return on investment. | |
