abstract

Not available – first paragraph follows:

Powdery mildew is undoubtedly the most widespread disease of roses. The casual fungus, Sphaerotheca pannosa var. rosae, appears as a white or gray powdery or mealy coating on the leaves, tender stems, and flowerbuds. It distorts and discolors those areas, causes defoliation, and reduces plant vigor.
