Initial Training for New Pesticide Applicators

In NH, if you apply pesticides on crops for sale and you employ workers, you need a private pesticide applicator’s license. This is true whether you apply general use OR restricted use materials. Those who apply pesticides to properties owned by others, whether or not payment is exchanged, need a commercial applicators’ license.

This spring, UNH Extension will offer trainings to help those who want to get their private (or commercial) pesticide applicator’s license.  Attendance at one of these trainings is not required, but will help attendees focus their studying and be ready to pass the exam.

Instructors will provide a review of the information found in the national pesticide applicator certification core manual, the NH code of administrative rules, and the worker protection standard for agricultural pesticides. The actual test will be held the last day of training in each location.

The dates and locations of the trainings are:

  • Cheshire County: Mondays, 1-4pm. Mar 5, 12 and 19.
  • Merrimack County: Wednesdays, 1-4pm. Mar 14, 21, and 28.
  • Coos County: Mondays, 1-4pm. Apr 16, 23, and 30.

Melon grafting: Hands-on demo

Recently grafted melon seedlings (Photo: Janel Martin).

Janel Martin recently received her M.S. Degree under the guidance of Dr. Brent Loy, a world renowned melon and pumpkin breeder, studying how grafted melons might benefit New England growers by reducing sudden wilt. You may have heard about her results: her grafted melon plants showed excellent resistance to sudden wilt, outstanding vigor, and increased yields of very high quality fruit. (She shared her results at last year’s Cucurbit School; you can view her presentation here).

We’re excited to have her here leading a hands-on demo, where she will pass on the tips and tricks she learned for creating healthy and vigorous grafted seedlings. The demo will take place Wednesday, March 7, in Boscawen, NH from 4:30-6pm.

Each participant will have the chance to work through the process along with Janel and finish a few melon seedlings of their own. You will learn how to create a healing chamber, the grafting process, pitfalls to avoid, and where to get supplies. The cost for the workshop is $10, to cover materials.

You can access the flier here; and you can register online here. For questions about registration, contact mary.west@unh.edu or 603-796-2151.
