Diagnosis Report
Guidelines to capture clear photo
Follow these rules to get an accurate disease diagnosis report:
Bring leaf close to camera
Hold the infected leaf close and flat so leaf spots are clearly visible.
Capture in bright daylight
Take photos in bright day lighting. Avoid dark shadows or blurry focus.
Focus on a single leaf
Focus on the damaged leaf rather than the whole crop branch.
🌾 Crop Disease Identification Guide and Protective Measures
Crop diseases are caused by fungal, bacterial, and viral pathogens. Failure to diagnose and treat these diseases in time can result in crop losses ranging from 30% to 100%. KisaanBuddy utilizes advanced AI vision models to analyze visual symptoms on leaves and provide immediate, actionable treatment recommendations.
🌾 Major Crops and Common Plant Pathogens
1. Rice (Paddy): Blast Disease and Bacterial Leaf Blight (BLB)
Blast causes diamond-shaped spots on leaves with gray centers. BLB exhibits wavy yellow-white stripes starting from the leaf tips. Avoid excess Nitrogen and spray Streptocycline combined with Copper Oxychloride.
2. Wheat: Yellow, Brown, or Black Rust
Appears as powdery orange, brown, or black pustules on leaf surfaces, heavily driven by wind and humidity. Spray Propiconazole 25% EC and cultivate rust-resistant varieties like HD-3086 or HD-2967.
3. Maize: Maydis Leaf Blight
Characterized by elongated rectangular brown lesions on leaves. Treat seeds with Carbendazim or Thiram prior to sowing and ensure proper crop rotation.
4. Cotton: Black Arm / Bacterial Blight
Angular dark brown leaf lesions that spread to stems, turning them black. Apply Streptomycin sulfate and clean field residues after harvest.
5. Tomato & Potato: Early and Late Blight
Early blight creates concentric ring spots (target lesions). Late blight is highly destructive, showing dark water-soaked leaf lesions that rot whole plants within 72 hours. Treat with Mancozeb or Metalaxyl.
🛡️ Integrated Disease Management (IDM)
A. Cultural and Biological Control
- Perform seed inoculation using Trichoderma viride bio-fungicide (5-10g/kg of seed).
- Incorporate Neem Cake (de-oiled neem seed residue) into the soil during field preparation to repress nematodes.
- Practice strict crop rotation to disrupt host cycles of persistent pathogens.
B. Chemical Interventions
- For fungal pathogens, spray contact-plus-systemic mixtures like Carbendazim + Mancozeb (SAAF) at 2g per liter of water.
- For bacterial infections, dissolve 6g Streptocycline and 500g Copper Oxychloride in 200 liters of water per acre.
❓ Crop Disease FAQs
Q1. How can I differentiate Rice Blast from Bacterial Blight?
Rice Blast produces diamond-shaped spots on leaves. Bacterial Blight displays elongated yellowing dry streaks starting from the outer edges of the leaf blades.
Q2. What is the main benefit of Seed Treatment?
It eliminates seed-borne spores, improves seed viability and germination rates, and shields early seedlings for 30 to 45 days.
Q3. How do we treat Potato Late Blight?
Spray prophylactic fungicides like Mancozeb before winter fog sets in. If symptoms appear, apply systemic fungicides like Metalaxyl-Mancozeb immediately.
Q4. Can biological agents suppress soil-borne pathogens?
Yes, beneficial soil microbes like Trichoderma and Pseudomonas put up active competition against Fusarium and Pythium root rots.
Q5. What causes Leaf Curl in Cotton?
It is caused by the Cotton Leaf Curl Virus (CLCuV), which is vectored by Whiteflies. Controlling the whitefly vector using Imidacloprid or Neem Oil is essential.
Q6. When is the best time to apply fungicides?
Fungicides should be sprayed in calm winds during early mornings or late afternoons. Avoid mid-day sun, which can cause phytotoxic leaf burns.
Q7. What causes Blossom End Rot in Tomato?
It is a physiological disorder due to Calcium deficiency, not a pathogen. Maintain consistent watering and apply foliar sprays of Calcium Nitrate.
Q8. How does crop rotation reduce disease build-up?
Pathogens are host-specific. Planting a non-host crop (like pulses after cereals) starves the spores remaining in the soil, reducing infection load.
Q9. What are the symptoms of Fusarium Wilt?
Plants exhibit sudden wilting and leaf drooping without prior yellowing, caused by fungal blockage of vascular water-conducting tissues.
Q10. How accurate is the KisaanBuddy disease model?
Our deep learning models identify 120+ diseases across 30+ staple Indian crops with a field-tested validation accuracy of over 95%.
