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.
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.
Preventive Measures
- Choosing resistant varieties is the primary preventive measure.
- 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.
Chemical Control
- Regent insecticide helps promote healthy flowering as well as the maturity of the plants which will increase the yields. It helps the plants to be greener, increases the overall leaf surface areas and promotes height increase. The plants will develop better root systems and more tillers that are productive. The dosage is 1.5 ml in one litre of water and is sprayed onto the leaves.
- Lancer gold insecticide is a combination of two systemic insecticides in powdered form. The main ingredients here are Acephate 500 and Imidacloprid 1.8 % SP which are readily soluble in water and are easily absorbed by the plants. It is effective against many sucking and chewing insects. The pests are controlled by contact and are effective against many insects including leafhoppers. The dilution ratio is 2 gm in one litre of water.
- Alika insecticide is an effective insecticide with the dual action of contact and contact & systemic to eliminate the pests. The active ingredients here are Lambda-cyhalothrin and Thiamethoxam which can control the pests and improve the growth and development of the plants with better foliage and more branches. The recommended dosage is 0.5 ml per litre of water or use 80 ml per acre.
