The Pesticide Applicators Training Workshop 2010
Pesticide Applicators Training Workshop will be
held Feb. 16-18 at Two Rivers Convention Center in Grand Junction. This workshop gives commercial and private pesticide applicators the opportunity to get all the continuing education credits needed to maintain their license with the Colorado Department of Agriculture in one meeting. Continuing education credits will be offered for UT, NM and WY. If you need credits for other states, contact Bob Hammon and we will try to get them set up.
We will have workshop registration information up by mid November. Registration will be $50.00 for private applicators (no meal), $110 (1 day), $135 (2 day) or $160 (3 days). Meals are included with full day registrations.
