Jassid, also known as leafhopper, is one of the common pests that affects Bengal gram (chana) crops in many parts of India. These small, greenish insects suck sap from the leaves and tender shoots, causing the plants to weaken. If the attack is severe, the crop may show stunted growth, curling of leaves, and reduced pod formation. Understanding the reasons behind jassid infestation and adopting simple management practices can help farmers protect their Bengal gram crop and ensure good yield.
Jassids usually appear during dry and warm weather. They prefer fields where the crop is tender and has soft leaves. When the pest population is high, the leaves start turning pale green, then yellow, and finally brown. Affected leaves may curl, showing a characteristic “hopper burn.” In severe cases, the plant dries prematurely, reducing flowering and pod development. Jassids also spread faster in fields with poor nutrition, uneven growth, and lack of proper pest monitoring.
The first step in managing jassids is preventive care. Farmers should choose recommended and tolerant varieties of Bengal gram that can withstand jassid attack better. Early sowing during November helps the crop escape heavy pest pressure because jassids become more active in late winter. Maintaining proper spacing between rows allows good air movement, which helps reduce pest buildup.
Balanced nutrition also plays an important role. Excess nitrogen makes the plants tender, which attracts jassids. On the other hand, adequate potassium strengthens plant tissues and improves resistance to sap-sucking pests. Applying well-decomposed farmyard manure and maintaining soil health reduces the chances of pest outbreaks.
Regular field monitoring is essential. Farmers should check the crop every 5–7 days, especially during early growth stages. Looking at the underside of leaves helps identify early infestation. If the population is still low, simple measures like shaking the plants and using sticky traps can help reduce their number.
Neem-based products are very useful for early-stage control. Spraying neem oil or neem seed kernel extract disrupts the feeding activity of jassids and slows their multiplication. These sprays are safe, low-cost, and suitable for repeated use.
When the infestation is moderate to high, farmers may need to use recommended insecticides. The best time to spray is when jassids are seen in large numbers on the tender leaves. Spraying should be done in the early morning or late afternoon for better effectiveness. It is important to cover the lower leaf surface because jassids usually hide there. Farmers should always follow the recommended dose and avoid overuse to prevent resistance.
Maintaining field hygiene also helps. Removing weeds from the field and borders reduces the alternate hosts where jassids survive. Avoiding water stress is equally important, as stressed plants are more vulnerable to insect attack. Light irrigation during dry spells helps the crop remain healthy.
In simple words, jassid problems in Bengal gram arise mainly due to warm weather, tender plant growth, nutrient imbalance, and lack of timely monitoring. By sowing at the right time, maintaining proper spacing, using neem sprays, and applying insecticides when needed, farmers can effectively manage jassids and protect their Bengal gram crop.
