Detail:

Leaves of young gram plants are devoured by green caterpillars of <i>Heliothis armigera<i>, which later bore into pods and cause wholesale damage to the crop. The damage is particularly severe in winter. An inexpensive mixture made from the leaves of the common wind killer plant "arni" (<i>Clerodendrum phlomidios</i>) locally known as <i>arni<i> and leaves of custard apple (<i>Annona squamosa</i>) is being traditionally used in Bharuch region of Gujarat to control damage by these pests in pigeonpea <i>Cajanus cajan</i> crop. Crush equal quantities of wind killer leaves and custard apple leaves and crush them. Mix 3 kilograms of crushed leaves to 20 litres of water. Boil till the volume is reduced to about 5 litres. Store the solution in suitable a container. Dilute 200 millilitres of this solution with 10 litres of water and spray on the caterpillar-afflicted crop. Within a week, 30 to 40 per cent control is achieved over the pest with just one spray. It is repeated as necessary to gain full control.
