What's That? Christmas Tree Pest Management Webinar Series

Feb. 8, 15, 22, and 29, 2024
12:30 to 2 p.m. ET

Successful pest management is vital for growing quality Christmas trees. There are many pests that can cause damage during a tree rotation. Identifying, quantifying, and determining the best course of action for pest management can be challenging. Incorrect decisions can result in inadequate control and create additional secondary pest populations. Watch Christmas tree experts from across the country discuss management practices to successfully control pests in Christmas tree production. Topics will include Integrated Pest Management, aphids, adelgids, and disease control.

There is no cost to attend this webinar, however registration is required. RUP credits will available for some states.
