Usage
Spray 200 liters of water plus 5 to 6 liters of Brahmastram per acre.
Note
We should not use grinder or mixture to make the leaves paste. Paste should be made using hand and stone. These leaves have Alkaloids and they are volatile in nature, if we use Grinder or mixture to make the paste due to heat the alkaloids may get evaporated.
Insects which sit inside the fruits/vegetables/grains/millets cannot be controlled by Brahmastram. For these type of insects we need to use Agniastram.
