Biostimulants-Nothing but the Facts

Biostimulants are products that have the potential to optimize plant growth and performance through a variety of mechanisms. Benefits as diverse as improved fertilizer usage, reduced pest pressure and fighting off abiotic disorders are but a few. From silicon and mycorrhizae to a host of newer products, Rick will call them the way he sees them. “Show me the data”!

*9:45-10:30 am, Joyce Latimar, retired VA Extension
PGRs for Perennial Production

The growth habits of herbaceous perennials vary from gentile to rowdy. Joyce will provide a brief outline of plant growth regulators (PGRs) available for use on perennials. Then she will focus on dealing with the rowdy crowd with an emphasis on PGR application techniques designed to reduce worker contact and environmental impact.

Spotted Lanternfly in WNY: Update on Erie County Detection and What This Means for Horticulture Businesses

The Spotted Lanternfly arrived first in New York in 2020 and is now established in parts of the Binghamton area. This invasive planthopper can become a real nuisance in landscapes and is a threat to vineyards. In this session we’ll review images of this insect so it can be recognized in its different life stages which range from tan egg masses to tiny crawling black nymphs to the adult with polka dotted outer wings and bright-orange underwings. We’ll describe its life cycle and the favorite plants it feeds on. From there, you’ll see the latest maps of where spotted lanternfly is located and learn of the regulatory work with this invasive insect.

Integrating Biologicals and Biorationals into Greenhouse IPM Programs

[Instructor Application to be submitted to NYS DEC]
Does it seem like your go-to products for greenhouse pest management are becoming less effective each year? Have supply chain issues left you in the lurch and unable to get pesticides that are a standard in your IPM toolbox? Tired of having to shut down your greenhouse for a 12 to 24-hour after spraying? All of these challenges (and more!) can be addressed if you can effectively integrate biological/biorational products into your IPM programs. This session will cover: 1) benefits of adding “bios” to your IPM toolbox, 2) several types of bios that can be easily integrated into conventional IPM programs, and 3) a “how-to” on maximizing efficacy for each type of product discussed.

4:25 – 4:30 pm
Wrap-Up, Evaluation, DEC certificates – Adjourn
