Muck Onion "Research Scouting" Program
Christy Hoepting, Extension Vegetable Specialist
Cornell Vegetable Program

To keep our fingers on the pulse of insect and disease pressure in muck onion production in our supporting counties, CVP Onion Technicians scout a handful of fields weekly counting disease lesions and onion thrips. Scouting reports are sent to grower cooperators complete with Cornell recommendations. This is a way of evaluating effectiveness of pest management programs, as well as a means of helping onion growers to implement onion IPM by spraying for pests only when they need to be.
Scouting usually begins in June and finishes in mid- to late-August. For more information, contact Christy Hoepting.
