How neemastra is prepared ?

Neemastra is made by crushing 5 kg neem leaves in water with 5 lit cow urine and 2 kg cow dung. This mixture is then fermented for 24 hours with intermittent stirring. After filtering , squeeze the extract and dilute to 100 lit. This can be used as foliar spray over one acre. Also useful against sucking pests and mealy bugs.
