New leaves with powdery mildew become bumpy before this fungi's trademark white or gray powder-like substance appears on both the leaves and blossoms. Although powdery mildew won't kill the plant, it mars a rose bush's beauty. Prevent powdery mildew by growing roses in a dry area with lots of sun and air circulation. Shrub varieties, such as hybrid tea roses and grandifloras, are most resistant to this fungus.
