Synopsis Insecticides, the chemicals used to control harmful insect pests, play an important role in modern agriculture. Although they are used extensively for protection of agricultural crops against noxius pests yet they are thought to be major pollutants of food and environment. This book furnishes a detailed account of insecticides, their properties, mode of action, biotransformation, uses on different agricultural crops, the problem of toxicity, residues, resistance and environmental contamination. The ways and means towards safe use of insecticides to avoid the fear of insecticidal hazards are explained in depth. The chapters on intervention of insecticides in IPM programme and insecticidal act are of special interest.
