In the Southeastern U.S., beef cattle producers focus on forage management and maximizing the grazing season. To that end, Southeastern cattle spend the vast majority of their lives either grazing or consuming stored forage. Cereal grains and coproduct feeds are also commonly used nutritional supplements for cattle in times of elevated nutrient requirement. Any disease or disorder in the beef herd represents a nutrient drain and subsequent economic inefficiency. Sudden shifts in dietary composition as well as mineral imbalances are the primary causes for most nutritional and metabolic disorders. This publication contains an overview of the common nutritional and metabolic disorders that may affect beef herds in the Southeast along with management strategies that can be used to minimize the effects of these disorders in beef cattle production systems.

Trap crops are sacrificial plants that can draw damaging insects away from valuable crops. Small-market growers, as well as homeowners, are experiencing greater pressure to produce quality vegetables due to increasing insect activity. There is also concern among both growers and the public about environmental sensitivity. This publication introduces the effective and environmentally friendly use of trap crops as an alternative to controlling damaging insects in the vegetable garden.

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.
