Plant Pests and Diseases Resources

Many species of insects or mites attack Georgia landscape plants. Homeowners have difficulty controlling these pests because they often are not aware of the problem until both the infestation and the damage are extensive, or they may apply insecticides improperly or at the wrong time. Brief descriptions of major groups of pests (or the damage they cause) found on Georgia landscape plants are provided to assist with identification. Control strategies for these pests are presented in Table 1.

The silverleaf whitefly, also known as the sweet potato whitefly or Bemisia tabaci (Hemiptera: Aleyrodidae), attacks a wide range of plants, from ornamentals to warm-season vegetables. Whiteflies are active from mid-July to mid-October and are found gathered together on the underside of leaves during the daytime. Although 76 whitefly species are known to exist in the Southeastern U.S., only a few species cause serious problems in greenhouses and nurseries. These species include the greenhouse whitefly (Trialeurodes vaporariorum), banded wing whitefly (Trialeurodes abutiloneus), giant whitefly (Aleurodicus dugesii), citrus whitefly (Dialeurodes citri), cloudywinged whitefly (Dialeurodes citrifolii), and the silverleaf or sweet potato whitefly. Among several whitefly species, the silverleaf whitefly, particularly biotype B, is the most common and most destructive whitefly species in
nurseries in the Southeastern U.S.|

This publication provides updated (2023) 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 performance of the pesticide will always conform to the pest control standards indicated by experimental data.
