Dutch Elm Diseases Management

The webinar presentation on Dutch Elm Disease will discuss the impact of this disease on communities as well as some of the history of how it has been managed. Biology of the disease, along with diagnostic tips to differentiate DED from other elm conditions will be covered. Current management tools and strategies are described, with a basic description of the process involved in performing macro-infusion of preventive fungicide against DED.

The Macro-Infusion Process: How to Use, Tree Injection Best Practices, & Equipment Maintenance

Utilizing the macro-infusion process for DED, oak wilt, and chlorosis management requires mastery of little details for success. In this webinar Chris Haugen will cover the finer points where many tree care and landscape professionals experience challenges to fast uptake, even distribution, and predictable results. Everything from the basic equipment maintenance, proper drilling technique, and troubleshooting the common pitfalls to macro-infusion will be covered in detail.

Scales in the Eastern US and Hemlock Woolly Adelgid Management

Scale insects are common pests of landscape trees that can cause serious harm to plants. The unique feeding habits and lifecycle of these pests can make control difficult. Hemlock Woolly Adelgid (HWA) is an invasive pest that is killing hemlock trees native to the Eastern United States. HWA is similar to some scale insects in the way it feeds, reproduces, and spreads from tree to tree. During this webinar we'll discuss the basic traits of scale insects and look specifically at the lifecycle and management protocols for:

  • Magnolia scale
  • White prunicola scale
  • Elongated hemlock scale

Additionally we'll look at the history of HWA in the Eastern US. Attendees will learn about HWA’s biology and responsible management protocols.

Presenter: Patrick Anderson, Arborologist, Rainbow Treecare Scientific Advancements

Patrick is an Arborologist with Rainbow Treecare Scientific Advancements. He has a B.S. in Forest Science from Penn State University (2004). He began working on a tree care crew in 2003, where he learned to climb trees and started his career in plant health care by applying treatments for Dutch elm disease and oak wilt. Since then he has served in all aspects of the tree care industry. Patrick’s role as an Arborologist is to provide client technical support and field training. Responsibilities also include supporting Rainbow Territory Arborists from a technical standpoint, setting up research/demonstration trials, in addition to giving talks and guest lecturing for green industry groups.
