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.

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.

Soil fumigants alone or in combination with nonfumigant nematicides can provide vegetable growers effective and reliable control of plant-parasitic nematodes, profitable yield and product quality, and increased profits. Treating soil with fumigant nematicides has been very beneficial to vegetable growers in Georgia, but environmental concerns may restrict the broad usage of these products. Telone II has been an important nematode management tool for the field production of many vegetable crops. Vegetable growers will have very limited options if soil fumigants, in particular Telone II, are no longer available. The development of new effective and environmentally safe nonfumigant nematicides has reduced the dependency on fumigant nematicides, but the application of fumigants still has great value for growers in Georgia.

Most cases of groundwater contamination by agricultural chemicals have been caused by improper storage or mixing and loading chemicals. For this reason, agricultural chemical storage and handling practices have been targeted by federal and state legislation across the United States. To satisfy the proposed regulations, dealers and applicators are encouraged to construct safe chemical storage and mixing/loading facilities with secondary containment.

Integrated pest management (IPM) is a sustainable approach to managing pests by combining biological, cultural, physical and chemical tools in a way that minimizes economic, health and environmental risks. One hundred and seventy-eight horticultural producers were surveyed in 2009-10 to determine the IPM practices used by growers in the southeastern U.S. Growers were asked a series of questions about monitoring or scouting for pests, prevention practices or interventions used to control pests.
