More than two generations of gardeners have practiced their craft with the arsenal of chemical pesticides and herbicides developed since WWII. The "e;folk knowledge"e; used for generations prior to that, much of which does indeed have a "e;scientific"e; basis, is largely unused and even forgotten today. Much of the more recent scientifically based research into alternatives has had limited distribution.As the "e;green movement"e; grows stronger in Canada, and pressure increases to limit the use of cosmetic pesticides and herbicides within urban and even rural municipalities, there is a growing need for information about effective alternate tools. The desire to go "e;chemical free"e; is there. Here are the tools to make it possible, with comprehensive, understandable, workable practices.
