    Introduction and Table of Contents

    Beginning in 2022, the Home & Garden Edition has been updated biennially. When purchasing a product based on a first-year recommendation of the Handbook, check the current product label before purchase to be sure it is still labeled for the use for which you are buying it. For pesticide products you have on hand from earlier purchases, you are allowed to use them until they are depleted without penalty under the law. Always follow label instructions before use. Contact the product’s manufacturer for the most up-to-date label.

    Georgia Pest Management Handbook — Home and Garden Edition

    The Georgia Pest Management Handbook gives current information on selection, application and safe use of pest control chemicals. The handbook has recommendations for pest control on farms, around homes, urban areas, recreational areas, and other environments in which pests may occur. Cultural, biological, physical, and other types of control are recommended where appropriate.

    Silverleaf Whitefly: A Pest in Nursery and Greenhouse Ornamental Crops

    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.

    Pulse Width Modulation Technology for Agricultural Sprayers

    This publication provides information on pulse width modulation (PWM) technology including its working principle, components, benefits, and best management practices for its optimal utilization on agricultural sprayers. Agricultural sprayers are commonly used for pesticide applications and come in various design types and sizes, including three-point hitch, pull-behind, and self-propelled. During pesticide applications, maintaining a target application rate across the whole field is important for effective pest management. On sprayers with traditional flow-based control systems, the liquid flow rate is regulated to account for ground speed variations by adjusting the spray pressure. However, this becomes an issue when spray pressure reaches outside the narrow operating range of the selected nozzle and results in non-uniform droplet size and pattern. Higher spray pressures at faster travel speeds produce finer droplets which are more prone to spray drift; applications at lower pressures produce coarser spray droplets and reduce spray fan angle. Pulse width modulation technology was developed to overcome this pressure variation issue; pulse width modulation does not rely on spray pressure to regulate system flow rate with changes in ground speed. In pulse width modulation systems, the flow rate is varied by changing the intermittent cycling of the electronically actuated solenoid valves while the system pressure remains constant throughout the boom.
