This publication contains important information on the biology of the causal agent, detailed descriptions of the disease symptoms (aided by high-quality, detailed pictures), relevant up-to-date information on conditions favoring the disease, and cultural, genetic and chemical methods of control. This publication is intended for turfgrass professionals, consultants, county faculty, homeowners, and general public.

Wheat leaf rust, caused by the fungus Puccinia triticina (formerly known as Puccinia recondita f. sp. tritici), is often a destructive foliar disease of wheat in the state of Georgia. Rust fungi in wheat are highly specialized pathogens with narrow host ranges. This circular provides information on symptoms and control of leaf rust for wheat growers in Georgia.

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.

Spring dead spot (SDS) is a persistent and destructive disease of bermudagrass (Cynodon sp.) in Georgia. The disease can be problematic on lawns, landscapes, golf courses (bermudagrass greens, tees and fairways) and sports fields. The disease is particularly prevalent and damaging in north Georgia, especially in the Piedmont region. However, SDS can be observed throughout the state after harsh winters and in areas where bermudagrass has been exposed to freezing temperatures for extended periods of time. The disease has also been observed in zoysiagrass, although less frequently. This publication explains how to identify and control Spring Dead Spot in lawns in Georgia.
