Concept, Principle and Application of Biological Control and their Role in Sustainable Plant Diseases Management Strategies

Abstract

Plant pathogens causing major damages to crop plants include fungi, bacteria, viruses and nematodes. Crop losses are creating a major threat to the food production with about 27 to 42% loss in global food production attributed to plant disease caused by plant pathogens which otherwise would have been doubled if no disease management strategies are applied (Singh, 2014).
