When you say "chemicals", I assume you mean man-made pesticides, herbicides and fertilizers. Surely you make use of the chemical compound H2O. My major objection to man-made pesticides is that many do not break down and have half lives of 20 years or more. In Australia the two major ofenders have been banned the chlorinated hydrocarbons and organophosphaphates. Mostly, natural or synthetic pyrethrum, is the only pesticide available to home gardeneres (The Fragrant Garden sells Quassia chips - not legally as a pesticide - but thats another story.) Our problem now seems to be how ro stop white ants eating the thing we spend most of our money on - our houses Michael Bailes, The Fragrant Garden, Portsmouth Road, Erina. N.S.W. 2250 Australia.
