MG Workshops present ...
Organic Pesticides & Herbicides in Your Gardens.

Friday, June 19 2026.
1:30pm - 3:00pm

Room 503 in Groth Hall, UA campus, Sierra Vista
1140 N Colombo

We will discuss the safe use of organic pesticides and herbicides in your vegetable gardens as well as in your landscape ... to focus on safe pest and w**d control while maintaining good health of your soil.

We can expect a heavy group of pests this year, after winter rains to feed foliage and winter warmth which did not kill off many over-wintering insect eggs. And with the predicted generous monsoon rains ahead, we can expect an abundance of w**ds.
Now is a good time to think about your organic plan of control.

Workshop fee of $10.00 paid at the door, cash or check.

REGISTRATION IS REQUIRED, please, to ensure adequate seating.
TO REGISTER, please TEXT or call 520-559-7078.

Coffee & bottled water will be available for you.
Happy Gardening!

- Cost of the class? 2 levels.
Level A: $175. Asks for 50 hours volunteer time within 1 year of graduation, which is able to be achieved in several ways. 50 hours really does go quickly, and students say they learn as much by volunteering as they did in class. Level A includes MG certification, and a textbook.

Level B: $275. No volunteer hours required. No certification is granted. But, the same coursework and information is provided, plus the textbook.
