ABSTRACT

 

Application of chemical pesticides and fertilizers show a long term residual toxic and teratogenic effects on the different animals and thus causing human health hazards after being incorporated into the ecosystem1,2. Chemical fertilizers and pesticides have provided food for first green revolution which now switches to use of biofertilizers and biopesticides in current era of organic farming and ecofriendly management practices4. In order to develop a low-input, Eco-friendly Technology,-following recommendations involving use of-Azolla, Azotobacter, Azospirillum, blue green algae and phosphate culture in different crops have been released for farming community by Anand Agricultural University, India. International 3rd Eco Expo Asia, October conference and trade fair (2011) has already given emphasis on "Green Technologies Govts. of Environmental Bureau decided to minimize - a low carbon environment and introduction of Bio-Organic Fertilizers including other policies in 2011.13 Thus, alternatively biofertilizers and particularly the biopesticides are now used including at least one chemical pesticide5. Here, in this paper, an attempt has been made to construct a biopesticide and biofertilizer, absolutely based on biological origin without any inclusion of chemical pesticide. These are especially related to paddy cultivation.
