This integrated pest management (IPM) guide for blackberry and raspberry production includes management of diseases, insects, and weeds through IPM principles. The 2024 Southeast Regional Caneberry Integrated Management Guide covers topics such as pesticide stewardship and safety, insect and disease control, pre-transplant and transplant operations, fungicides 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 application methods are on the pesticide label, and these are subject to change at any time.

As Georgia’s pecan production acreage has increased, reports of insect pests that attack younger, less established trees have also increased, particularly infestations by pecan bud moth and ambrosia beetles. This circular summarizes the pertinent insect pests that attack young, non-bearing pecan trees, including key details on their biology, injury, monitoring, and management. This information should be helpful to both new pecan growers and experienced growers with newly established orchards.

This resource covers lace bugs in landscapes, which can damage the foliage of trees and shrubs and detract from their beauty and, in severe cases, kill the plants.

Annual ryegrass (Lolium multiflorum), also referred to as Italian ryegrass, is the most problematic winter annual weed in Georgia hayfields. Seed germinates from September to November when soil temperatures drop below 70 degrees F. Seedlings mature in the fall, overwinter in a vegetative state, and resume active growth in the spring. Annual ryegrass is a prolific seed producer that contributes to annual infestations.
This publication summarizes the growth and identification of this weed. Cultural and chemical control options are also presented for tall fescue, bermudagrass, alfalfa, bahiagrass and other forage legumes grown for hay production.

The silverleaf whitefly (SLWF), Bemisia tabaci, (also known as sweet potato whitefly) is a pest of a wide variety of horticultural and agronomic crops in southern Georgia. Adults and nymphs (Figure 1) have piercing-sucking mouthparts and feed on phloem, the transport tissue of plants, and remove plant sap. While this direct feeding can damage plants and lead to additional problems with the accumulation of honeydew and sooty mold, whiteflies also inject salivary fluids while feeding, which can result in plant disorders and transmission of plant viruses. When viral pathogens are present, their transmission creates the greatest threat to the economical production of many vegetable crops, particularly tomatoes, snap beans, most cucurbit crops, and occasionally, cole crops. The potential for whitefly pest problems and viral disease incidence in Georgia varies greatly by year, location, and production season. Recent experience indicates that greater viral incidence can be observed when pest populations are high, even though few viruliferous (virus-carrying) whiteflies are needed to inoculate individual plants.

Summer squash is one of the most popular warm season vegetables grown in home gardens. Unfortunately, the levels of insect attacks on summer squash have risen dramatically over the last 10 years. Safe and effective controls are needed to help produce this important crop with all of the pressures of insect pests. This publication will discuss both organic and non-organic solutions for homeowners to try in their home garden, including the use of barriers, trap crops and chemical controls.
