Registration is Now Open for MSU Extension’s Workshop on Fog Use in Greenhouses

Michigan State University (MSU) Extension, in partnership with Deneweth’s Garden Center and other industry collaborators, is hosting a one-day educational workshop titled “I Have No Fogging Clue! Using Ultra-Low Volume Sprays in the Greenhouse.” The workshop will be focused on greenhouse fogging and ultra-low volume (ULV) application technologies. Designed for commercial greenhouse growers, managers, staff, and technical advisors, 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; as well as strategies for successfully integrating biorational products into greenhouse 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.
