Fairy ring is an umbrella term for a disease that can be caused by more than 60 different species of basidiomycete fungi. It is particularly damaging on golf greens, but can affect all turf species in Georgia. Infection leads to localized dry spots and nutrient imbalances. No single strategy guarantees complete control, but integrating thatch reduction, water management, fertility optimization, and targeted fungicide applications can significantly mitigate disease impact.

Canola Production in Georgia
Growing canola profitably takes planning and good management. All aspects of production, from seed selection to harvest to marketing, must be taken into account if the grower is to make a profit. Land preparation, fertility management, weed and other pest control, and timely harvest and marketing are all components of a good canola production package. Before you grow canola, dedicate yourself to make “best management practices” a part of your production system.

Mite Management in Turfgrass
Plant-feeding mites can cause serious damage in turfgrass systems, and drought-stressed turfgrass is particularly prone to mite infestation. Mites are generally active in turfgrasses from spring into fall. They feed on plant sap and, in some cases, also inject toxins into plant tissues or manipulate plant growth, thereby producing characteristic symptoms. Some mites do not directly damage the turfgrass but instead become nuisance pests by moving from the lawn to houses and other buildings. This circular discusses the biology, damage, and management of the various mite species that attack turfgrass.

This publication provides updated (2025) Southeast-specific information on approved National Organic Program (NOP) disease and pest management options for blueberry production and addresses the issues most commonly encountered under the unique growing conditions of the Southeast U.S. This publication is not intended to provide all details on organic blueberry production, although it does include the production methods that reduce the impact of plant disease and pest issues. Emphasis in an organic system should be on cultural practices that reduce disease and pest pressure rather than pesticide applications. NOP-approved pesticides are usually less efficacious than conventional products. The pesticide label is the law and supersedes any information on pesticide use contained in this guide. Because environmental conditions and grower application methods vary widely, suggested use does not imply that the performance of the pesticide will always conform to the pest control standards indicated by experimental data.

Rose rosette virus can cause major problems for nurseries, landscapers, and gardeners alike. The virus causes the plants to become undesirable and will eventually result in the death of the plant, which affects all segments of the rose industry as well as rosarians and home gardeners. The symptoms of disease on ornamental roses are a yellow mosaic pattern appearing on leaves, increased thorniness, abnormally shaped foliage and early production of lateral buds that make up the witches’ broom. This publication is intended for rose producers and serious rose gardeners interested in technical details of this virus and a mite that transmits it.
