Michigan State University Extension, in partnership with Deneweth's Garden Center and industry collaborators, is hosting a one-day educational workshop focused on greenhouse fogging and ultra-low volume (ULV) spray application technologies. Designed for commercial greenhouse growers, managers, staff, and industry professionals, the program will provide practical information on application methods, worker safety, and the use of biorational pest and disease management products.
Sessions will cover the fundamentals of fogging and ULV technologies; proper respirator selection, fit testing, and personal protective equipment (PPE) requirements; and strategies for successfully integrating biorational products into greenhouse integrated pest management programs. Participants will receive research-based guidance from MSU Extension specialists, industry experts, and occupational health professionals.
A highlight of the workshop will be a greenhouse demonstration comparing ULV and conventional spray applications. Using dyed water applications documented in advance, attendees will observe differences in coverage and application performance. Additional presentations will discuss the effectiveness of applying biorational products through fogging and electrostatic sprayers, as well as important considerations related to re-entry intervals, greenhouse air exchanges, and worker safety following applications.
The event will also provide valuable opportunities for networking with industry suppliers and service providers. Lunch and exhibitor tables will allow participants to connect with representatives from leading horticultural companies and learn about current products and technologies.
Eligible participants are expected to receive six Michigan Restricted Use Pesticide (RUP) recertification credits. This workshop will combine university expertise, industry knowledge, and hands-on learning to help greenhouse professionals improve application efficiency, protect workers, and make informed pest management decisions.
