9:00 am – 10:00 am Key Pest Management With Systemic Insecticides
Jeff Picher, Rainbow

With the arrival of spring comes the start to a new season. The long winter means this year’s disease and pest management window is going to be compressed.

In this session, we will discuss how systemic insecticides can help you manage key pests in the region including emerald ash borer. We’ll cover:

• What pest issues in the region to look out for
• How to identify the top issues
• What your management options are to ensure that your clients’ trees are taken care of

The Spotted Lanternfly continues to expand into new territory in Pennsylvania and is now known to exist in Virginia. The Pennsylvania Department of Agriculture has enacted a quarantine order to try to reduce the spread of this insect.

In this session, Emelie Swackhamer (Penn State Extension) will provide an update on this invasive pest, describe the biology of the spotted lanternfly, and highlight observations about problems it caused in 2017.

1:00 pm – 2:00 pm Growth Regulators Best Practice for Managing Landscape Plants
Joel Spies, Rainbow

More and more companies are using plant growth regulators to change how they manage their clients’ landscape trees, shrubs, hedges, and vines. Using a PGR has a number of benefits including:

• Reducing the number of pruning cycles and labor requirement for plant maintenance
• Improved safety, scheduling capabilities, and labor allocation
• Improved health and appearance of the plant

In this session, we will discuss how you can incorporate plant growth regulators into your business and the benefits they can have. We’ll also look at best practices when applying PGRs and how to ensure optimal results.

2:00 pm – 3:30 pm Plant Health Care Equipment Field Demonstrations
Jeff Picher, Rainbow

During this session, we will demonstrate the best practices and proper application techniques for a variety of plant health care protocols including:

• Soil injections of tree growth regulators using the HTI-2000
• Foliar applications of shrub growth regulators using the JD-9 spray gun
• Insect management using micro-injections, soil applications, and bark sprays
• Vascular wilt disease management using macro-infusion

We will also discuss what the toolbox approach to plant health care is and what the benefits are to the business, the client, and the plant.
