Dear editor,
I am honorary Canadian observer on the umbrella U.S. Pesticide Working Group. I live in suburban Ottawa and have a substantial lawn maintained in an
excellent condition, without any pesticides and with very little effort. Few people know that herbicides were unavailable for weed control prior to WWII and were initially used for military purposes.
The lawns in my neighbourhood tend to be quite large and despite the Ontario ban, in effect since the spring of 2009, are kept in an entirely satisfactory condition.
