    Lantana Lace Bug Biology and Management

    The lantana lace bug, Teleonemia scrupulosa Stål (Tingidae: Hemiptera), is a serious pest of lantana (Lantana
    camara L.). Although lantana is regarded as an invasive weed both in the United States and worldwide,
    many popular cultivars continue to be planted in residential and public ornamental landscapes and gardens.
    Previously, the lantana lace bug was deliberately introduced to several countries as a biological control agent for
    lantana. Te lantana lace bug is also referred to as T. lantanae or T. vanduzeei in many publications. This publication covers the identification, biology, symptoms and management of lantana lace bugs.

    2023 Southeast Regional Caneberry Integrated Management Guide

    This integrated pest management (IPM) guide for blackberry and raspberry production includes management of diseases, insects, and weeds through IPM principles. The 2023 Southeast Regional Caneberry Integrated Management Guide covers topics such as pesticide stewardship and safety, insect and disease control, pre-transplant and transplant operations, fungicide and insecticide efficacy comparisons and spray schedules, weed management, wildlife damage, and more. Recommendations are based on information from the manufacturer’s label and performance data from research and extension field tests. Because environmental conditions and grower application methods vary widely, suggested use does not imply that performance of the pesticide will always conform to the safety and pest control standards indicated by experimental data. This publication is intended for use only as a guide. Specific rates and applications methods are on the pesticide label, and these are subject to change at any time.

  • 2020 Georgia Plant Disease Loss Estimates

    AP 102-13

    2020 Georgia Plant Disease Loss Estimates

    2020 plant disease losses in Georgia, including control costs, amounted to an estimated $806 million. The value of the crops used in this estimate was approximately $6.712 billion, resulting in a 12.01% relative disease loss across all crops included in this summary. The estimated values for most crops used to compute these disease losses are summarized in the 2020 Georgia Farm Gate Value Report (AR-22-01) by the UGA Center for Agribusiness & Economic Development. Some estimates for fruits, ornamentals, and turf rely on specialists’ knowledge of the industry and industry sources for information. Losses covered include: apple, blackberry, blueberry, bunch grape, corn, cotton, muscadine grape, ornamentals, peach, peanut, pecan, soybean, strawberry, turfgrass, vegetables, and wheat.

    How to Control Citrus Leafminers

    Citrus leafminer (Phyllocnistis citrella) is found in Georgia and states along the Gulf of Mexico. Leafminer damage to foliage can stunt the growth of young trees and make trees more susceptible to citrus canker where the pathogen is present. Mature trees can better tolerate the damage although heavy infestations may reduce production. This publication discusses the identification, chemical control, noninsecticidal control, and homeowner control options for citrus leafminers.

    Azalea Bark Scale

    Azalea bark scale (ABS) poses a serious threat to azaleas, rhododendron, and Pieris (Andromedas) in Georgia. ABS is a soft scale insect; the nymph and female soft scales secrete a protective coating of waxy crust on their body that cannot be separated from the scale insect. ABS also is found on blueberry, hawthorn, huckleberry, poplar, and
    willow. ABS is found in cracks or crevices in the surface of the bark, and also in areas where azalea branches fork. ABS can undergo two generations per year in Georgia.
    Symptoms of ABS infestation include dropping yellow leaves and dying branches. Developing nymphs and females excrete a sugary syruplike liquid called honeydew on to the bark and leaves. As time passes, the surface of the bark, and sometimes the leaves, turns black because it gets infested with a sooty mold fungus that
    feeds on the sugary secretions. The white crusts of scale insects are easily visible when the azalea bark turns completely black. An ABS infestation rarely kills the plant unless it is extremely severe and uncontrolled.

    Sugarcane Beetle: An Emerging Insect Pest in Georgia Turfgrass

    The sugarcane beetle has been a significant pest of many crops, including sugarcane, corn, sweet potato, and rice, for more than 100 years. It is a native species commonly found in turfgrass. While low numbers of beetles in an area generally are not regarded as pests, increasing numbers of adult beetles have been causing damage to turfgrass stands throughout the Southeastern U.S.

    The adult sugarcane beetle is about ½ in. long, and is black with small punctures along the elytra, or wing covers, that create long, lengthwise stripes. Its first pair of legs have four serrations that make the beetle a strong digger. As a result, adults are known to damage asphalt roofs, door gaskets, and other soft structural elements
    when lights attract them to buildings. The larvae of sugarcane beetles are C-shaped grubs, which are similar in appearance to other white grub species. Third-instar larvae can reach up to 1¼ in. long and are identified by their creamy white bodies with reddish-brown head capsules.
