All About...Plant Diseases

Powdery Mildew

Numerous strains of fungi are commonly referred to as Powdery Mildew.  Since this disease removes essential nutrients from the plant, leaves may become yellow, stunted or drop off prematurely.

Black Spot

Roses, especially hybrid tea roses, are highly susceptible to this infectious fungal disease. Black spots, as the name implies, will appear on the leaves, followed by a yellowing surrounding the spots.
