the judgement from the suprem court http://www.lexum.umontreal.ca/csc-sc...hudson.en.html
I'm from Quebec Canada and it's true about the ban. Between snowstorm i go to university following a turf and yard maintenance programs and we are now working for pest free grass. our biggest problem was the compact poor clay soil. after we stop the treatment 2 years ago we get mostly dandelion and clover problem. we change our cultural pratice, and with core aeration and compost spreading the result was good. Grass is green and more resistant to droughness. Some client now wants little flower in their grass to encourage biodiversity.
Now I listen to the weeds, they are the response of mother nature about soil problems.
