Neem leaf extract

Neem leaf extract is effective as a foliar spray against sucking and chewing insects. It can also be applied directly to the soil to control nematodes in brinjal and tomato. Placing of neem leaf in coconut gardens after receipt of monsoon rains controls root grubs.

Take one kilogram of neem leaves, crush it and soak it overnight in five litres of water. Dissolve 25 gram of soap in 250 ml of boiled water and add to the above solution before spray. Instead of bar soap five packets of shampoo sachet can also be used.
