Bengal gram, also known as chana or chickpea, is an important rabi pulse crop grown across India. It gives good income and improves soil fertility. However, pests like jassids (leafhoppers) can cause serious damage, especially during early crop growth. If not controlled in time, jassids can reduce plant vigour, limit pod formation, and ultimately lower the yield. Understanding how to identify and manage this pest helps farmers protect their crop effectively.
Jassids are small, light green insects that suck the sap from the underside of leaves. Their feeding causes the leaves to turn yellow at the edges, curl downwards, and eventually dry up. This condition is often called “hopper burn.” In severe cases, the plants become stunted and fail to produce enough flowers and pods. Jassids multiply quickly in dry, warm conditions, especially when the crop is stressed or when weeds are present in the field.
The first step in managing jassids is prevention. Farmers should choose resistant or tolerant varieties of Bengal gram whenever possible. Seed treatment with suitable insecticides also gives early protection by preventing the establishment of jassids during the initial growth stage. Healthy seedlings with strong roots can tolerate pest attack better than weak plants.
Maintaining field hygiene is very important. Weeds act as hosts for jassids, so removing them regularly reduces the chances of pest buildup. Avoid planting Bengal gram close to crops that attract jassids, such as cotton or vegetables like okra and brinjal. A clean field helps keep the pest population low from the beginning.
Balanced nutrition also plays a major role. Overuse of nitrogen makes the plants tender and attractive to jassids. Instead, applying the right amount of phosphorus and potassium strengthens plant tissues and improves resistance. Well-nourished plants can handle mild pest attack without much loss in yield.
Farmers should monitor the crop carefully, especially during the first 40–50 days. Regular field visits help in early detection. Checking the underside of leaves is important because jassids hide there. If farmers see leaf curling or yellow margins, it is a sign of infestation.
When jassid population crosses the economic threshold level, timely insecticide spraying becomes necessary. Farmers should use recommended insecticides and follow the correct dosage and spraying method. Using a knapsack sprayer with a hollow cone nozzle ensures proper coverage on the leaves. Spraying should be done in the early morning or late evening when the insects are more active and the temperature is low.
Avoid using the same insecticide repeatedly, as this can lead to resistance. Rotating chemicals with different modes of action helps maintain effectiveness. Farmers should also avoid unnecessary spraying because it harms beneficial insects that naturally control pests.
Irrigation management is also useful. Although Bengal gram needs very little water, a timely light irrigation during dry periods helps reduce crop stress. Plants under stress attract more jassids.
In summary, managing jassids in Bengal gram requires a combination of preventive practices, regular monitoring, weed control, balanced nutrition, and timely insecticide application. With these steps, farmers can keep jassids under control and achieve a healthy, productive Bengal gram crop.
