2023 Georgia Ag Forecast Series: 2023 Fruits and Tree Nuts Outlook
1. The three major U.S. peach-producing states experienced a significant fall in production which cumulatively reduced our 2022 production by 15%. Since it is difficult to predict whether the weather and water shortage that contributed to the decrease in production will persist, chances are that the situation may improve in 2023, but not by much. 2. The significantly high price received by…
Beneficial Insects of Pecan Trees
Accurately distinguishing insect pests from beneficial arthropods is a critical component in the implementation of an effective and sustainable pest management program. This circular provides a succinct and practical summary of natural enemies commonly found in pecan orchards in the Southeast U.S.
Budding and Grafting of Pecan
Individuals who propagate trees have their own personal preferences with regard to propagation methods. As with many practices related to pecan production, timing is important for successful propagation.
Clover Management in Pecan Orchards
An orchard floor provides a working surface for orchard operations and influences activities in the trees, which produce the crop. An efficient orchard floor cover does not compete heavily with trees for moisture and nutrients and is compatible with orchard insect populations. While weed competition with tree roots is significant throughout the life of the tree, in a newly planted orchard, weed co…
Commercial Pecan Spray Guide
This publication provides guidance for insect, disease, and weed control in commercial pecan orchards for 2023.
Cultural Management of Commercial Pecan Orchards
In order for a commercial pecan operation to be consistently successful, the goal of the operation should be annual production of a moderate crop of high quality nuts, rather than the production of a high yield in a single given year. Culturally, there are several basic factors that will help to promote optimum profitability with a commercial pecan orchard.
Drip Irrigation in Pecans
Research conducted on drip-irrigated pecans in Georgia over the past several years has shown that drip irrigation is highly beneficial even in wet years. The objective of drip irrigation is to supply each plant with sufficient soil moisture to meet transpiration demands. Drip irrigation offers unique agronomic, agrotechnical and economic advantages for the efficient use of water.
Establishing a Pecan Orchard
A well-planned, organized orchard will be more efficient, require less input and offer larger potential returns. Select the orchard location based on its soil type, drainage, water table and land topography. Straight rows in planted orchards make maintenance, irrigation and harvest easier. Tree growth and spacing requirements can also be anticipated for the early planting and subsequent orchard th…
Hedge Pruning Pecan Trees in the Southeastern U.S.
As pecan trees grow in an orchard, their tree canopies encroach upon one another, causing excessive shading, which can increase alternate bearing intensity and reduce tree health and orchard profitability. Historically, limb pruning and tree removal have been the most common methods of dealing with this problem, particularly in the low-light environment of the southeastern United States. Mechanica…
Herbicide Injury of Pecan Trees
Georgia pecan orchards are often found growing adjacent to fields of annual row crops, timber, and pastures. As a result, the tree canopies of these orchards are susceptible to injury from herbicide drift from the adjacent operations when herbicide applications are made under conditions unsuitable for spraying. Drift may also occur when cotton fields are sprayed with chemical defoliants in the fal…
Insect Pests of Non-bearing Pecan Trees
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 sho…
Mouse Ear of Pecan
Mouse ear of pecan is a growth abnormality resulting from a deficiency of nickel in the pecan tree. Only recently, the discovery was made that mouse ear indicates a severe nickel deficiency. The disorder occurs most frequently on newly transplanted trees in established orchards, but can also occur on sites where pecan has not previously been grown.
Nutritional, Environmental and Cultural Disorders of Pecan
Although many problems regarding pecan production result from pest or disease pressure, the crop may also be adversely affected by nutritional imbalances, nutrient deficiencies, or environmentally induced disorders. These are some of the more difficult problems to diagnose. Some nutrients may be more available than others on certain soil types and under certain soil conditions. Additionally, compl…
Organic Pecan Production
Organic food production is one of the fastest-growing sectors of the American food marketplace and is driven largely by personal health preferences and environmental ethics. Organic food sales in the United States rose from $13 billion in 2005 to $35 billion in 2014. Organic farmers are required to follow an ecological soil management program and are restricted in their use of chemicals. In order …
This circular is a calendar-based management reference for pecan production in the Southeastern U.S. It provides an easy-to-use graphical guide for management decisions regarding crop phenology, irrigation and fertilization requirements, disease, and insect and mite arthropod pest management. It also includes information on production activities including timing for planting, harvesting, and nutri…
Pecan Trees for the Home or Backyard Orchard
Pecan trees are commonly found surrounding both urban and rural dwellings throughout Georgia. They can enhance the environment and provide additional income from the sale of nuts. This publication contains comprehensive information about pecan trees for the home or backyard orchard.
Pecan Varieties for Georgia Orchards
The most fundamental step in pecan production is the selection of varieties or cultivars to be planted in the orchard. Planting the wrong pecan variety can be a costly mistake, resulting in considerable expense. This publication includes descriptions and photos of pecan varieties suitable for planting in Georgia orchards.
Southeastern Pecan Growers' Handbook
Pecan production is considered by many who practice this endeavor to be as much an art as it is a science. Growers must integrate multiple disciplines in order to be successful. This book was created with the goal of being a comprehensive reference text for pecan growers, scientists, and county agents. It addresses pecan culture and management in the southeastern United States. For more informatio…
