Panchakavya

Panchagavya is a concoction prepared by mixing five products of cow. The three direct constituents are cow dung, urine, and milk; the two derived products are curd and ghee. These are mixed in proper ratio and then allowed to ferment.
The mixture which is made using yeast as a fermenter, bananas, groundnut cake, and the water of tender coconut, is a potent organic pesticide and growth promoter. 
The Sanskrit word Panchagavya means "mixture of five products," and it has been used in traditional Indian rituals throughout history.
In recent years Panchakavya has found a prominent position in the context of organic farming in Tamil Nadu, India. It is also employed in the State of Kerala, which has embraced the organic agriculture movement fully.
This method is being adopted all over the world as an alternative to pesticides,herbicides and insecticides. It is a nature friendly method.
