Powdery mildew, caused by Blumeria graminis f. sp. tritici (syn. Erysiphe graminis) is an obligate, host specific fungus that attacks wheat exclusively. The pathogen reduces photosynthesis and increases respiration and transpiration rates in host leaves. Colonized plants lose vigor, impairing heading and grain filling. Heavily colonized leaves can be killed prematurely. This circular provides information on symptoms and control of powdery mildew for wheat growers in Georgia.

The southern chinch bug, Blissus insularis Barber, is a serious insect pest of turfgrass, especially St. Augustinegrass, in Georgia. Bermudagrass, centipedegrass, and zoysiagrass are also attacked by southern chinch bug. They feed on grass using their piercing and sucking mouthparts. Affected turfgrass can form yellow to brown patches that are sometimes mistaken as indicators of disease or drought stress. Populations of southern chinch bug can build up at the edges of these patches at over 100 individuals per square foot, which can kill the affected grass. The development of southern chinch bug in the grass can easily go unnoticed because of their small size and dark-gray color, which blends in with thatch. This publication summarizes the biology, lifecycle and management options available for southern chinch bug in Georgia.
