Learn about the most common diseases affecting Kharif crops like rice, maize, soybean, and pulses. Discover effective organic and chemical treatments, early identification tips, and prevention strategies to protect your crops in the 2025 monsoon season. A complete guide for Indian farmers.
Introduction: Why Kharif Crop Disease Management Matters
Kharif season, starting with the arrival of the southwest monsoon (June–October), is vital for Indian agriculture. Crops like rice, maize, pulses, millets, soybean, and cotton thrive in this season. However, high humidity, erratic rainfall, and temperature fluctuations make these crops prone to various fungal, bacterial, and viral diseases.
Without proper disease management, farmers may lose 20–50% of their yield. This blog covers the most common Kharif crop diseases, their early signs, and organic + chemical solutions tailored for Indian conditions in 2025.

Spreads Through: Spores in wind and rain.
2. Fall Armyworm in Maize
Symptoms: Holes in leaves, frass inside whorl, leaf skeletonizing.
Spreads Through: Caterpillars, especially in humid areas.
3. Soybean Rust (Phakopsora pachyrhizi)
Symptoms: Yellow-orange pustules on lower leaf surface.
Spreads Through: Windborne spores.
4. Fusarium Wilt in Tur (Pigeon Pea)
Symptoms: Yellowing, drying from bottom to top, black stem base.
Spreads Through: Soil-borne fungal spores.
5. Yellow Mosaic Virus (YMV)
Crop: Moong, Urad, Soybean
Symptoms: Irregular yellow patches on leaves, stunted growth.
Vector: Whiteflies
