Pesticide Free Gardening

We’re all familiar with handpicking Colorado potato beetles and the working end of a hoe. But there are many other tools we can use to avoid broad-spectrum chemical pesticides and many reasons why doing so is a good idea. These alternatives include cultural methods such as timing, traps and barriers (including mulch!) and the use of resistant plant varieties. What about less toxic products such as horticultural vinegars and oils? There is also an enormous range of natural predators and parasites from the lady beetle to lacewings. The newer biological tools include corn gluten meal, Bt and other bacterial formulations such as Bacillus subtilis (now there’s a story!). Your free registration in this class is sponsored by our Healthy Yards partner, the City of Saskatoon.
