Best Management Practices for Your Weed Control Program
Charles Gillam, Professor of Horticulture, Auburn University, Auburn, AL
Dr. Charles Gilliam is one of the leading weed scientists in the United States. He evaluates new chemicals for use in both container-grown and field-grown crops for many pesticide companies. Gilliam has worked with weed research for 30 years and has extensive experience in the nursery industry. He shares key principles of a good weed management program and new herbicide options now available.
Dr. Gilliam, Auburn University, studies herbicide efficacy in container-grown and field-grown nursery crops. Charles has a 75% Research, 25% Extension appointment in ornamental nursery crop production.
Weed control can be one of the most costly risks in the production of container-grown nursery crops. Any control program begins with the correct identification of the weeds present, along with an understanding of their life cycles and modes of reproduction and spread. Treated here are the most common weeds of outdoor container nurseries, as well as a selection of recently introduced species with the potential to spread. This work is based in large part on Weeds of Container Nurseries (Neal & Derr 2005), but builds on that treatment through the addition of multi-access keys, taxa, and images. The content is optimized for mobile use and should be accessible from standard browsers on nearly any device, whether desktop, tablet, or smartphone.

Do you care about protecting our native plant habitats from invasive plants? How can you tell which plants are invasive? Do you want to know how you can help? First step is to come to the Georgia Exotic Pest Plant Council Annual Conference on November 8th.
The GA-EPPC, Georgia Exotic Pest Plant Council, is having its Annual Meeting and Conference on Thursday, November 8th, 2012, from 9am to 4pm. The conference will be held at Stuckey Conference Center, UGA 1109 Experiment Street Griffin, Georgia.
GA-EPPC’s goals are to focus attention on the adverse effects invasive plants have on the diversity of Georgia’s native plants and animals; the use of invasive plant management to prevent habitat loss; the socioeconomic impacts of these plants; changes in the seriousness of the different invasive plants over time and the need to exchange information to help land owners and managers set priorities for invasive plant management.

Weed management is one of the most critical and costly aspects for container nursery production. High irrigation and fertilization rates create a favorable environment for weed growth in addition to crop growth. Weeds can quickly out-compete the crop for light and other resources, reducing the rate and amount of crop growth as well as salability (Berchielli-Robertson et al., 1990; Norcini and Stamps, 1992). Weed management in nursery production is most effectively achieved by preventative practices, primarily with the use of pre-emergent herbicides (Gilliam et al., 1990; Gallitano and Skroch, 1993).
However, there are valid reasons for managing weeds using alternatives to synthetic herbicides (Sidebar 1). Ornamental crops encompass a wide array of species, and herbicide products must be tested on each for effective, safe and legal use. Even when a product is labeled for a crop, it may not be sufficiently effective for the weeds present or may induce crop damage under certain circumstances. Finally, use of synthetic herbicides in greenhouses and other enclosed structures is often prohibited on product labels.

Southeastern nursery growers now have a new best friend when fighting pests and diseases. A new book, available in hard copy and iBook format for iPads, is now available, thanks to the Southern Nursery IPM Working Group.
The book—IPM for Select Deciduous Trees in Southeastern US Nursery Production—is a compilation of information about IPM for the major tree genera in nursery crop production in the southeast. The 320-page iBook covers sustainable management for insects, mites, disease, and weeds for the top-selling deciduous trees, as well as propagation and production information, genus by genus. The book demonstrates how each aspect of production can impact pest problems and management. Each chapter is centered on one crop, so answers to pest problems with “birch” or “dogwood” are easy to find.
The iBook includes movies illustrating techniques like grafting, hand-digging, and more as well as a custom glossary for terms specific to nursery production and pest management. While this resource is invaluable to nursery growers, landscapers, arborists, garden center owners, students and educators will also find it useful.
IPM for Select Deciduous Trees in Southeastern US Nursery Production was written by university Extension specialists in nursery production, plant pathology, entomology and weed science with partial support by the Southern Region IPM Center in Raleigh, NC.

A NEW publication by Shawn T. Steed and Robert H. Stamps at The University of Florida/IFAS
Glyphosate is the largest-selling single crop protection chemical worldwide (Woodburn 2000) and the most used herbicide in the nursery industry in the United States (Norcini et al. 1996). It is used for postemergent control of vegetation. Glyphosate is an extremely effective chemical that controls a broad spectrum of annual and perennial grasses, broadleaves, and sedges. This herbicide acts as an inhibitor of an enzyme that leads to the formation of several essential amino acids required for normal protein synthesis. Glyphosate has the ability to spread throughout the plant and concentrate in the growing regions where these amino acids are most needed for new growth. As a nonselective, translocating herbicide, it is easy to cause unintended damage to desirable vegetation if this product is used incorrectly. This publication outlines the proper use of glyphosate for plant producers and their employees.
