Weeds, Diseases and Pests

The flatheaded appletree borer is a polyphagous pest—so called because it feeds on multiple tree species—native throughout North America. Flatheaded appletree borers impact specialty crops such as fruit, nut, and ornamental trees. Nursery growers in Georgia face mild to moderate levels of infestation depending on the local beetle population size and favorable environmental conditions. Adult flatheaded appletree borers are metallic greenish-bronze and appear fattened in cross-section, which causes them to produce “D” or oval-shaped exit holes as they emerge from wood; these exit holes commonly are associated with buprestid beetles. The elytra or wing covers of flatheaded appletree borer adults have markings that appear as light-colored zigzagging bands. Larvae are cream-colored and have an enlarged, fattened thoracic segment behind the darker true head of the insect—this is what gives them the flatheaded name.

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.|

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 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.

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.
