The first digit (D1) indicates disease progress in the canopy relative height of the disease using the original 0-9 Saari-Prescott scale as a measure and the second digit (D2) refers to measured severity based on diseased leaf area as a percentage but in terms of 0-9. Because it is difficult to evaluate diseases on dead leaves, disease notes should be taken when at least four leaves are still alive and green (soft to mid-dough growth stage). Then visually evaluate the average percentage severity on only those leaves of the uppermost four that are infected. In practice, the percent severity is estimated on an overall score, D2 scoring severity: 10% coverage = 1, 20% coverage = 2, 30% coverage = 3, 40% coverage = 4, 50% coverage = 5, 60% coverage = 6, 70% coverage = 7, 80% coverage = 8, 90% coverage = 9.
