We have planted some drumstick plants PAVM variety. Some plants have leaf being eaten by caterpillar small green/white ones. They eat the leaves and make small webs in the plant and the half eaten leaves become brown and dry up.
I have sprayed neem leaf extract. Surprising thing is there is one small neem tree where similar problem persists, the caterpillar has eaten the neem leaves.
Please suggest what to spray to control.
