"Alternatives to Glyphosate: How Do They Compare on Annual and Perennial Weeds?"
Joe Neal, Ph.D., Department of Horticultural Science, NC State University

Joe discusses weed control. Whether you agree or disagree with recent reports of an association between glyphosate and non-Hodgkin’s lymphoma, many people are searching for alternatives for postemergence control of weeds in landscape beds. Joe will demonstrate and discuss the efficacy of alternative herbicides and "natural" products, with particular attention to efficacy on annual vs. perennial weeds.

"Preparing Young Trees for a Better Future"
Barbara Fair, Ph.D., Department of Horticultural Science, NC State University

Want to reduce future costs and minimize stress on your trees? Join Barbara Fair as she shares pruning techniques aimed at building strong structure for the future growth of trees.


12:00 pm–1:00 pm

Landscape Professional Sessions

1:00 pm–3:00 pm – Afternoon Indoor Sessions (Ruby C. McSwain Education Center)

"Managing Work Flow and Costs by Job" Connie Hoyes, Southern Gardens, Inc.

Connie will cover the principles of an individual job from the time you win the bid through purchasing the materials mobilizing to the site, using labor, and subcontractors effectively, tracking all costs, and determining if your estimate was truly what transpired throughout the execution of the work from start to finish.

"What the last 15 years at the NC State Plant Disease and Insect Clinic can — and cannot — tell us about tree and shrub problems in North Carolina"
Mike Munster, NC State Plant Disease and Insect Clinic

Some landscape trees and shrubs are known for their susceptibility to particular diseases or disorders, while others seem to get a wide range of problems. In this talk we will explore examples of both, and we will review how to effectively take samples for disease diagnosis.
