Leafhopper or Indian cotton jassid is a common pest affecting several types of crops in India. Its nymph appears in translucent green colour with no wings and is seen between the veins under the leaf. The adult pests are green and wedged. Here is some more information about its infestation in cotton and how to control them.
Leaf Hopper in Cotton Symptoms
The tender leaves become yellowish and their margins will curl downwards. Severe infestation leads to reddening of the leaves or becoming bronze coloured, which is called hopper burning. The curled leaf margins will be crumbled and broken, leaving the leaves dry which affects the growth of the plants.

- Crop rotation by choosing this species that can resist these pests will be the other way of reducing leafhopper infestations.
- The third method is to choose the most favourable growth period for the plant, especially April-May so that it can easily resist the infestation and does not majorly impact the growth.
