Detail:

Infestation of green larvae leads to a loss of crop production due to their sucking out nutritive elements from the leaves as well as pulses. Therefore, Nathabhai Vankar suggests a solution formed by soaking two kilogram mahuva (Madhuca indica) flowers in two litres of water. This solution is then sprayed on the crop of pigeon pea (Cajanus cajan) and pearl millet (Pennisetum typhoides) for the control of green larvae infestation. This successful technique has been learnt by the farmer from his elders.
