Mixture of cow dung, Calotropis plants, neem(Azadirachta indica) cake and human urine to enhance resistance to insect attack and diseases in plants. V R Iyyappan from the Reddiyapattii village of the Thadikombu district in Tamil Nadu uses a special mixture to increase resistance to insect attack and diseases in plants. Iyyappan digs a pit of a convenient size near an irrigation well or channel. He fills the pit with cow dung, Calotropis plants and neem(Azadirachta indica) cake. He also adds human urine to this mixture. When the mixture fully decomposes, the water from the irrigation channel is allowed to pass over the pit and enter the field. Iyyappan believes that this process not only provides nourishment to the plants but also enhances their resistance to insect attack and diseases
