Armyworms in Sod
It is not unusual for fall armyworms to infest newly planted sod in a home landscape, especially during late summer to fall. Not all fall armyworm problems originate from sod farms but instead begin near the home landscape where sod is installed. This resource explains the biology and seasonality of fall armyworm in Georgia and discusses possible management strategies to mitigate infestation.

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.

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.

Scale insects are common pests of landscape trees and shrubs that are often overlooked when scouting. Scales can be responsible for chlorosis, branch die-back, and ultimately, plant death. Scales are broadly categorized as either soft scales or armored scales. Soft scales produce a soft, cottony, powdery, or waxy substance that cannot be separated from the scale body. Common soft scales in Georgia include Indian wax scales, Florida wax scales, brown soft scales, oak lecanium scales, magnolia scales, cottony maple scales, cottony camellia scales, cottony cushion scales, and azalea bark scales. Armored scales have a hard, shield-like cover that is not attached to the body of the insect. Common armored scales in Georgia include tea scales, euonymus scales, obscure scales, false oleander scales, juniper scales, and gloomy scales.

The red-headed flea beetle is a serious insect pest in ornamental nurseries. It is also referred to as the “cranberry flea beetle” in cranberry and blueberry systems in the Northern U.S. The adult beetle causes serious feeding damage to the foliage of a variety of woody and herbaceous container plants in nurseries. As the name suggests, the flea beetle jumps when disturbed, similar to a dog flea. A native pest, this insect is present in central and eastern U.S. regions.
