Nothing is more welcoming in the home, office, waiting room, or conference room than lush greenery. The benefits of plants in the home and workplace are well-documented. They remove pollutants, help workers relax and refocus, increase productivity, and make the room look better. Unfortunately, plants often come with the nuisance pest fungus gnats. Learn how to what they are, how they live, and how to control them.

The brown marmorated stink bug is a landscape and agricultural pest in the United States. They seek dark and dry sites—such as a vehicle parked near trees—in the fall in which to overwinter. This pest is reported to feed on more than 170 plant species, including fruits, vegetables, and ornamental plants. This stink bug also is a nuisance pest as they aggregate and overwinter in man-made structures beginning in late fall.

The crape myrtle bark scale (CMBS) is an emerging threat to crape myrtle (Lagerstroemia spp.) in Georgia. As the name indicates, this scale pest attacks the bark of crape myrtle, the only known scale insect that infests crape myrtle bark. A native of Asia, CMBS was first confirmed in Dallas, Texas, in 2004. Since then, the pest has gradually expanded its range to the southeastern states. In Georgia, it was first confirmed in Coweta County in 2014. In 2019, CMBS were found infesting crape myrtles in an ornamental nursery in south Georgia. They can potentially spread in zones 6 to 9.

Grazon® P+D (picloram + 2,4-D) injury, diagnosed as leaf roll, is occasionally observed in Georgia peanut fields due to the presence of contaminated soil, forage, animal waste (manure/urine), and/or irrigation water. Since peanut plants are very tolerant of low levels of 2,4-D, the primary cause of these leaf roll symptoms is picloram. When this injury occurs, growers are often concerned about how it can potentially influence final peanut yield.

Stubby-root nematodes, Paratrichodorus minor, are considered an important pest of onions in Georgia. Low to high population densities of this nematode were observed in multiple fields in the Vidalia area causing damage to sweet onions. The most obvious aboveground symptoms of stubby-root nematode nematode infection are poor, stunted growth of onion seedlings. Stubby-root nematodes have a wide host range, including sugar beets, potatoes, corn, cotton, peanuts, wheat, onions, grasses and some other vegetable crops that are commonly grown in Georgia. Fallow crop rotation with non-host cover crops and treating seedbeds with suitable fumigant and non-fumigant nematicides are effective controls for this pest.

This quick reference guide provides an overview of common pests and predator groups and their sizes, habitat preferences, and timing in cotton fields. This visual guide is intended to help facilitate future scouting and provide information on common predatory arthropods in Georgia cotton systems. When growing cotton, scouting for key pests and beneficials is critical to making informed and cost effective management decisions.
