Identification of Black spot on roses.
    

APPEARANCE:

Azalea leaf gall is a very common and widespread fungus disease that occurs in early spring on new azalea foliage. The leaves become thickened, curled, fleshy and pale green to white in color. Fortunately, this disease is more alarming than damaging.

Susceptible Turfgrass:

St. Augustine grass is most commonly attacked by gray leaf spot but it also attacks perennial ryegrass, Bermuda grass, centipede grass, bent grass and various species of fescue. Gray leaf spot is especially severe on new St. Augustine lawns.

Symptoms:

Sooty mold frequently develops on the foliage of many ornamental plants in late summer. It covers the top surface of leaves, thus, reducing the photosynthetic process of the leaf.
