These insects are attached to the knots of sugarcane in groups. They become visible when the crop is 4-5 months old and their effect remains till the harvest. The nymphs and the wingless females damage the leaves by sucking the sap. If there is drought, then its effect on the crop is more.

How to Manage?

Before sowing sugarcane, destroy the residues of the previous crop in the field. Do not use infected seeds at the time of sowing. Keep proper spacing in rows at the time of transplanting. Remove and burn infected leaf sheaths. Along with this Thiamothoxom 25 W.G. Dissolve the insecticide named in 2.5 liters of water and sprinkle it on the crop.

Black Stick

When the number of these pests is high, the field starts to stink. These insects suck the sap from the neck of the plants, causing yellowing of the leaves in the center of the plants. After some time the leaves dry up and the growth of the plant also stops.

How to Manage?

For its treatment, Thiomethoxam 25 W.G. Dissolve the insecticide named in 2.5 liters of water and sprinkle it on the crop.
