Vegetables and Fruits we eat are safe today? Obviously not so it may contain hazardous chemicals we spray on them in their production pathway. The vegetables and fruits we consume today may contain toxic residues. Last day one of my friends Mr.Anil Kumar came and asked me to suggest a pesticide for the control of Mango fruit fly? I told him to avoid spraying and a trap was advocated. He was satisfied. In my experience people want a quick remedy for pest Management. Pesticide application suddenly kills pest population and natural enemies of pest and may be congenial for development of another pest again we have to go for another pesticide finally the result is pesticide rich fruits and vegetables. In nature for every organism natural enemies exist and our task is to find out it and How to exploit them for pest management.
