Breeding Crops to Reduce Pesticide Dependence Raoul Robinson IDRC 1995 ISBN 0-88936-774-4 e-ISBN 978-1-55250-363-8 436 pp.
"We are approaching the biologic limits of what this planet can support. Only by implementing some of the basic concepts that have been advanced and publicized by Dr Robinson, can an increasing world population be fed, while preserving our natural resources and the quality of our environment." In the tradition of Silent Spring, Raoul Robinson's Return to Resistance calls for a revolution. Traditional plant breeding techniques have led us to depend more and more on chemical pesticides to protect ourcrops. Return to Resistance shows gardeners, farmers, and plant breeders how to use a long-neglected technique to create hardy new plant varieties that are naturally resistant to pests and disease. Horizontal resistance breeding has been largely ignored in this century due to the popularity and apparent successes of the Mendelian geneticists. However the colossal, unrecognized failure of modern crops is their extreme susceptiblity to pests and diseases, and the consequent necessity to spray them repeatedly with pesticides. We have come to accept exposure to pesticides in our food as a necessary evil. Return to Resistance provides
THE AUTHOR Raoul A. Robinson is a Canadian/British plant scientist with more than 40 years of wide-ranging experience in crop improvement for both commercial and subsistence agriculture. Over the course of his adventurous and productive career, Dr Robinson has concentrated most intensively on maize, potatoes, beans, and coffee. In addition, he has worked with cotton, tomatoes, dates, wheat, alfalfa, cocoa, cassava, coconut, tobacco, taro, sweet potato, vanilla, black pepper, and other crops.
