Abstract
POWDERY mildews occur on a variety of ornamental plants.
As the name suggests, these diseases always appear as a greyish white powdery coating on the leaves. This is easily removed by rubbing or weathering, but beneath it a dark web-like discoloration of the leaf surface often develops.
Under some conditions these diseases can be very serious and cause considerable defoliation, stunting and malformation in such plants as Roses, Lagerstroemia (Crepe Myrtle), Hydrangea, Michaelmas Daisy, etc.
