“…The results of this study showed a great annual variation in the SHD incidences of the evaluated four plum cultivars, which are in agreement with previous studies on various fruit species, e.g., [ 4 , 6 , 7 , 9 , 15 , 21 , 25 , 27 , 28 , 29 , 30 , 31 ]. Cultivars ‘Čačanska lepotica’ and ‘Bluefre’ showed high, SHD incidences, cv.…”

“…Cultivar susceptibility and training system affect the fruit disease epidemics of fruit species [ 6 ]. Cultivar susceptibility to SHD was studied in several fruit tree species, such as almonds [ 11 ], peaches [ 25 ], apricots [ 26 , 27 ], nectarines [ 28 , 29 ] and plums [ 7 ]. In plum studies, cultivars showed various susceptibility to SHD [ 7 , 30 , 31 ].…”

Shot hole disease (SHD) can cause severe epidemics in plum orchards, depending on cultivar susceptibility and training system; however, the combined effect on the progress of temporal disease and on the possible reduction in SHD in the disease management was not investigated. The aim of this 3-year study was (i) to monitor and analyze the temporal dynamics of SHD progress under four training systems (4 × 1.5, 4 × 2, 5 × 2.5 and 6 × 3 m) and on four plum cultivars (‘Čačanska lepotica’, ‘Bluefre’, ‘Stanley’ and ‘President’) in an integrated plum orchard; (ii) to identify those time periods when training system and cultivar combinations can reduce the disease development. Both SHD incidences and the area under the disease progress curves (AUDPC) were significantly affected by the training system, cultivar and year. Plum cultivars with high or mid–high susceptibility to SHD showed continuous SHD development from May to November, while cultivars with low susceptibility to SHD showed no symptoms until mid-summer and then progressed slowly until November. High (4 × 1.5 m) vs. low (6 × 3 m) density training systems reduced SHD incidence and AUDPC consistently for three cultivars (‘Čačanska lepotica’, ‘Stanley’ and ‘President’) in September, October and November, compared to the high-density training system. Only cv. ‘Bluefre’ showed no effect either on disease incidence or AUDPC, due to very high disease incidences in all training systems from September to November. In conclusions, combinations of training system and cultivar can significantly reduce SHD incidence, which may be successfully used as a part of the integrated pest management approach during the establishment new plantations.
