¹D = dwarf form (3-5 feet), SD = semi-dwarf (5-10 feet), ST = small tree (10-20 feet), LT = large tree (20 feet or larger).
²Powdery mildew was rated on a scale of 0 to 4 where 0 = no disease, 1 = 1 to 25%, 2 = 26 to 50%, 3 = 51 to 75%, 4 = 76 to 100% of the leaves damaged or colonized E. lagerstroemia.
³Cercospora leaf spot was evaluated using the Barratt and Horsfall System: 1 = 0%, 2 = 0 to 3%, 3 = 3 to 6%, 4 = 6 to 12%, 5 = 12 to 25%, 6 = 25 to 50%, 7 = 50 to 75%, 8 = 75 to 87%, 9 = 87 to 94%, 10 = 94 to 97%, 11 = 97 to 100%, 12 = 100%.
