Ask the Advisor: Common Pests in Greenhouses & Nurseries

About: Are you a grower who deals with thrips, mites, mealybugs, aphids, scale and plant hoppers? Drs. Daniel Hasegawa, Eric Middleton, Kirsten Pearsons, and Chris Shogren, will each give a short 5-6 minute talk covering their recent research into pest issues affecting greenhouse and nurseries. We will then have a 1 hour Q&A session where the panellists will share information about identification, scouting, and management (IPM & chemical) of common greenhouse and nursery pests, including aphids, mealybugs, mites, thrips, and whitefly, as they respond to questions from participants about pests in their operations.
