JAMESTOWN - Managing pests in enclosed greenhouse and high tunnel structures can be challenging, but these upcoming programs can help growers of all sizes. Cornell Cooperative Extension will offer practical lessons and tips you can use to better manage pests. DEC pesticide recertification credits (1 credit per one hour session) will be given in Categories 1A, 3A, 10, 23, 24. Only participants viewing the live sessions at an extension office will qualify for pesticide recertification credits. Each session can be viewed independently.
