Whenever crops are affected by pests, the stalks become weak and the grains become black in appearance. Even the plant develops a black colour and the yield decreases. To protect the crops from damage, the farmers of the Dangs region extract 2-3 l of juice from the fresh fruits of the mahua (Madhuca indica) tree. They then add four liters of water to it. This concoction is sprayed over the field. On spraying this mixture over a one acre farm leads to about 50% control over the aphid infestation. This is a traditional practice and has been in use for the last 15 years.
Formulation: Two to three liters of juice from the fresh fruits of the mahua (Madhuca indica) tree. They then add four liters of water to it and sprayed over the field.
Ingredients: Fresh fruits of the mahua tree (Madhuca indica)
