  • Figures indicating resistance to disease reflect the current situation. Susceptibility to mildew may increase quite rapidly in only a few years and it is therefore advisable to inspect crops of all varieties regularly for disease infection during the growing season.
  • If minimal fungicide usage is planned, varieties should be considered on the basis of their untreated yields. Where fungicides are to be applied, the fungicide treated yield should be a better guide bearing in mind that disease control measures used in trials are designed to keep disease to a minimum with no economic restrictions.
