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.

Fertilizer injectors are devices used to apply water-soluble fertilizers, pesticides, plant growth regulators, wetting agents and mineral acids during crop production. They are a vital part of modern greenhouse or nursery operations. Despite the advantages, many growers have had at least one experience with a compromised, damaged or even ruined crop where the cause was traced to a malfunctioning injector. Just like other mechanical devices, proper and frequent maintenance and calibration are crucial steps to ensure optimal injector performance and, thus, healthy crops.

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.

Additional author: Emma Moore, Department of Food Science & Technology. Satsuma oranges are a fast-growing commodity in Georgia. Satsumas are natural and excellent sources of sugars, organic acids, soluble fibers, vitamins, minerals, phytochemicals, and essential oils. Because of their nutritional content, satsuma oranges are considered functional foods (foods that provide health benefits and essential nutrition). Novel products may be produced from satsuma oranges and satsuma peels, including food ingredients such as soluble fibers and essential oils that may be appealing to health-conscious consumers interested in including more plant-based ingredients into their diets.
Fresh satsuma oranges have a short shelf-life. This publication describes the nutrients found in satsuma oranges and opportunities to develop high-value food ingredients from satsuma oranges. This information is timely and may help the local citrus industry diversify its current product portfolio. It also describes essential food safety concepts that may improve the overall competitiveness of the Georgia citrus industry.

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.

Additional author: Michael Ulyshen, Research Entomologist, U.S. Forest Service. This visual guide helps people identify common wild bees encountered in blueberry systems. The contribution of wild bees to blueberry pollination has is becoming widely recognized. Proper identification of these insects in the field is critical part of conservation efforts.

Red cabbage is a highly nutritious vegetable crop, rich in minerals, vitamins, and several other chemical compounds that are beneficial for human health, including phenols, proteins, glucosinolates and anthocyanins. While red cabbage belongs to the same group as the other cabbage varieties (white and green) widely produced and consumed in the state, red cabbage production and consumption in Georgia is still low. This publication contains basic information on crop management, food safety practices, and biochemical properties of red cabbage.

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.
