Biological Control: A Form of Manipulating Nature into Natural System

India is the heaven of agricultural products, its vast plains contain alluvial soil with rich natural contents. Major economy of India is based on agricultural products. Green revolution in India brought high hopes for Indian farmers. Several new scientific information helped crop production to grow by leaps and bounds. The more researches, the more intricacies. Further knowledge of pests makes scientists think about several other solutions. Use of chemicals was immediately adopted to curve the population of pests and good results were also obtained. But later on, harmful effects of the pesticides were also known. It was realized later on that the regular use of chemicals in pesticides creates danger for human health. A kind of ecological disturbance is caused unnecessarily. Over the next three decades, production of food grains in India was increased at least 2 million tonnes in order to meet the food demand of the growing population. Today, further prospects of raising agricultural production in the manner as in the recent past appear to be severally constrained. Land frontiers are becoming limited and opportunities to bring additional land under cultivation are being bedimmed.
