Preface
This work proposes methods of reducing, even eliminating,
the use of crop protection chemicals from our crops and
environment. It seems that this can best be achieved by self-
organisation (sensu Adam Smith) within agro-ecosystems. This
anisation can be brought about by numerous plant breeding
clubs that are employing durable resistance to crop parasites.
If we consider the food production of a country, we find a self-
organising system. Many farmers, acting individually, choose what
crops to grow, and what cultivars of those crops to grow. Their
decisions are based mainly on their environment, and on market
demand, es from the decisions of individual merchants
who buy their produce. Systems of transport and food processing
convert raw materials into marketable products, and retailers make
these products available to consumers through stores and super-
markets. These consumers choose what they buy, usually on a
basis of either cost or quality. The stores must stock items
according to customer preferences. There must be some
government control to ensure purity and hygiene, and to prevent
monopolies and cornered
