Gram, also known as chickpea or chana, is one of the most important pulse crops grown in India. Although it is hardy and well suited for dryland farming, the crop is highly sensitive to fungal diseases, especially when there is excess moisture or cloudy weather. Common fungal problems like wilt, root rot, collar rot, blight, and rust can severely affect plant growth, reduce flowering, and ultimately cause heavy yield loss. Timely prevention and proper field practices can protect the crop and ensure healthy production.
1. Major Fungal Diseases in Gram
Before controlling fungal problems, it is helpful to understand the common diseases:
Fusarium Wilt: Plants suddenly wilt and die; the stem becomes brown inside.
Root Rot / Collar Rot: Rotting at the base of the plant, seedling collapse.
Ascochyta Blight: Brown spots on leaves, stems, and pods.
Botrytis Grey Mould: White–grey fungal growth in humid, cloudy weather.
Rust: Orange or brown powdery spots on leaves.
Identifying symptoms early helps in effective control.
2. Use Disease-Free and Treated Seeds
Seed treatment is the first and most important step in preventing fungal attacks.
Farmers should:
Use certified, disease-free seeds.
Treat seeds with recommended fungicides or biopesticides before sowing.
This protects seedlings from soil-borne fungi and improves early growth.
3. Follow Proper Crop Rotation
Growing gram on the same field continuously increases fungal infection.
Rotate gram with sorghum, millet, maize, or oilseeds for 2–3 years.
Crop rotation breaks the disease cycle and reduces fungal presence in the soil.
4. Maintain Good Field Drainage
Fungal diseases spread quickly in fields with standing water.
To reduce risk:
Avoid sowing in low-lying or poorly drained fields.
Ensure good soil structure and proper leveling.
Maintain appropriate spacing between plants for air circulation.
Dry and well-drained conditions help keep fungi under control.
5. Improve Soil Health
Healthy soil supports strong plant immunity.
Apply:
Farmyard manure (FYM)
Compost
Vermicompost
Neem cake
These organic inputs increase beneficial microbes that naturally suppress harmful fungi.
6. Apply Fungicides When Needed
If disease symptoms appear in the field, timely fungicide sprays can prevent further spread.
For leaf diseases like blight or rust, farmers may need 2–3 sprays depending on weather conditions.
Start spraying at the early stage of infection for best results.
Use fungicides cautiously and avoid unnecessary spraying to prevent resistance.
7. Use Resistant Varieties
Many improved gram varieties have natural resistance to wilt and blight.
Choosing suitable varieties for your region reduces disease pressure and ensures better yield.
8. Avoid Excess Irrigation
Gram is a dryland crop and does not require frequent irrigation.
One irrigation at flowering may be enough.
Over-irrigation increases humidity and encourages fungal growth.
9. Keep the Field Clean
Remove infected plants and plant debris from the field.
Leftover infected material can spread fungus during the next season.
Deep ploughing after harvest exposes fungal spores to sunlight, reducing their survival.
Conclusion
Fungus in gram crops can be controlled effectively through a combination of preventive measures—seed treatment, crop rotation, good drainage, resistant varieties, and timely fungicide sprays. Healthy soil, proper spacing, and avoiding excess moisture play a major role in keeping fungal diseases away. With early identification and good field practices, farmers can protect their gram crop and achieve high, healthy yields.
