Bengal gram, also known as chickpea or chana, is a major rabi crop grown across India. It is valued for its high protein content and good market demand. However, one of the biggest challenges farmers face in Bengal gram cultivation is fungal diseases. Fungi attack the roots, stems, leaves, and even pods, weakening the plant and reducing yield. Understanding how fungal infections develop and learning effective control measures can help farmers protect their crops and achieve better harvests.
One of the most common fungal diseases in Bengal gram is Fusarium wilt. Infected plants suddenly droop and turn yellow, even when the soil has enough moisture. When uprooted, the roots appear brown and the internal stem tissues show discoloration. Another major disease is dry root rot, which causes the plant to dry up from the base. Collar rot, Ascochyta blight, and Alternaria blight are also frequently observed.
Fungal problems usually increase when the soil is poorly drained, the same crop is grown repeatedly, or the field receives too much irrigation. Early infection often begins from contaminated seeds or infected crop residues left in the field.
The first step in controlling fungus in Bengal gram is seed treatment. Treating seeds with recommended fungicides or biological agents like Trichoderma helps protect young seedlings from soil-borne fungi. This simple practice greatly reduces early-stage infections and improves germination and plant vigor.
Crop rotation is another effective preventive measure. Farmers should avoid growing Bengal gram or other pulse crops in the same field every year. Rotating with cereals like wheat, maize, or sorghum breaks the life cycle of the fungus and reduces disease pressure in the soil.
Improving soil drainage is crucial. Bengal gram is highly sensitive to waterlogging, and fungal diseases spread quickly in wet soils. The field should be well-leveled, with proper channels for drainage. Light irrigation should be provided only when necessary. Over-irrigation must be avoided at all costs.
Adding organic manure, compost, or neem cake helps improve soil health and encourages beneficial microbes that suppress harmful fungi. Healthy soil with good structure allows roots to grow stronger and resist infection.
Farmers should regularly inspect their fields. If fungal symptoms appear, infected plants should be removed and destroyed immediately to prevent spread. In cases of severe infestation, fungicide sprays or soil drenches may be required. Applying fungicides at the early signs of disease gives the best results.
Ensuring proper spacing between plants helps improve air circulation and reduces humidity around the crop. Crowded plants create a moist environment that favors fungal growth. Balanced fertilizer application—especially adequate phosphorus—strengthens the plant and improves resistance to disease.
Weed management is also important. Weeds compete for nutrients and moisture, weakening the crop and making it more vulnerable to fungal attack. Timely weeding ensures healthier crop growth.
By combining seed treatment, crop rotation, good drainage, balanced nutrients, weed control, and timely fungicide application, farmers can effectively manage fungal diseases in Bengal gram. Healthy plants with strong roots and good vigor produce better flowering, more pods, and higher yields, ensuring good income for the farmer.
