The single most important step is cultivar choice: it must suit the district and must not be susceptible to Sharka. The suggested spray programme by phenological stage, fertilisation, and the practices that decide the year.
Twenty-one modern apricot cultivars, one by one, from orchards followed in Pella, northern Greece. Breeder datasheets and field observation are kept strictly apart, and where they disagree both are given. Why resistant, tolerant and susceptible are three categories and not two, and why the absence of sharka symptoms is not the absence of the virus.
An aggressive disease that can take more than half the crop. The correct name of the pathogen, overwintering inside the dormant buds and why that load can be measured, the brown apical necrosis and vertical oozing canker forms, the per-tree risk scale counted in June, and the prayer-stage timing that is usually missed by ten days.
