Publisher's Synopsis
The use of pest control systems in the field is always a compromise between conflicting demands of principles and practice. The choice of compound, its formulation, its dosage and its method of application can only be made in relation to a knowledge of the pest-crop or pest-host relationship and the ecosystem in which they exist, and ultimately the answer lies in balancing the optimum parameters proposed by theory and the inevitable demands of practice. This book has therefore been designed to outline the principles underlying the choice and use of pesticides and pest control systems, and to illustrate how far these can be applied in a variety of practical situations.
