2. Improves Nutrient Content: Delivers essential nitrogen, phosphorus, potassium for robust growth and tuber development.
3. Builds Soil Microbiome: Stimulates beneficial microorganisms, which naturally suppress diseases like dry rot caused by Fusarium.
4. Reduces Disease Pressure: Healthy, well-structured soils foster resilience against fungal pathogens.

The integration of organic manure with precision fertilization strategies—guided by soil testing and crop nutrient modeling—is key to maximizing yield, improving tuber quality, and minimizing post-harvest disease risks in 2026 and beyond.

Dry Rot in Potatoes: Causes, Risks & Best Prevention Techniques

Dry rot in potatoes is a post-harvest fungal disease—mainly caused by Fusarium species—that leads to dry, sunken lesions. If left unchecked, it can devastate both storage and profits.

What Cause Dry Rot?

• ✔ Mechanical Injury During Harvest: Wounds during lifting, handling, or sorting are primary entry points.
• ⚠ Poor Storage Conditions: Excess humidity, fluctuating temperatures, and low ventilation promote fungal spread.
• 🌱 Soil-Borne Fusarium Levels: Persist in fields with a history of infected plant debris or excessive moisture.
• 🚩 Inadequate Skin Cure: Unhealed skin injuries post-harvest increase susceptibility.

Direct costs include immediate tuber losses, while indirect impacts are greater: lower market value, decreased storage life, and greater risk of secondary pathogens.

“Smart storage solutions extend potato shelf life by 40%, significantly reducing post-harvest losses through automated climate control.”

Integrated Measures for Preventing Dry Rot in Potatoes During Storage

• 1️⃣ Careful Harvesting: Reduce tuber injury—use sharp equipment and optimal tractor speed to limit skin breaks.
• 2️⃣ Curing: Cure potatoes for around 10 days at 12–15°C and 85–95% humidity. This allows minor wounds to heal before long-term storage.
• 3️⃣ Optimal Storage Conditions: Store in cool (4–10°C), dark environments at around 90–95% humidity. This reduces sprouting, dehydration, and fungal activity.
• 4️⃣ Regular Monitoring: Inspect piles weekly, remove any soft, discolored, or shriveled tubers to prevent rot spread.
• 5️⃣ Fungicidal/Biocontrol Treatments: Consider microbial biocontrol agents (where permitted) for fusarium control, as chemical reliance decreases globally due to pressure from consumers and regulators.

1. Smart Sorting Lines: Automated visual and NIR (near-infrared) sorting helps detect and remove suspect tubers quickly.
2. UV Sterilization: Some storage facilities now apply UV light to surfaces and air, lowering spore load.

Curing & Storing Potatoes After Harvest: Best Practices

“Curing” establishes a robust potato skin, ensuring resilience against rot and dehydration in storage. Here’s the step-by-step:

1. Field Airing: Allow freshly dug potatoes to briefly air dry in the field (weather permitting), facilitating initial set of the skin.
2. Controlled Curing Room: Move potatoes to a humidity- and temperature-controlled room for 1–2 weeks to fully heal minor injuries.
3. Sorting: Remove any tubers showing signs of injury, rot, or disease right after curing.
4. Final Storage: Place only healthy, firm tubers into bulk stores or ventilated bins.

For all steps, darkness is essential. Light exposure leads to greening and production of solanine, which can be toxic.

Advanced Storage Solutions & Smart Systems for Potatoes in 2026

• ✅ Darkness: Always store potatoes in a dark environment to inhibit sprouting and solanine buildup.
• 💧 Humidity Control: Maintain storage humidity at ~90–95% to slow dehydration, but avoid condensation (which increases rot risk).
• 🌡 Temperature Management: Target 4–10°C; lower for table potatoes, slightly warmer for seed potatoes (to prevent cold damage).
• 🔄 Ventilation: Use smart ventilation—either mechanical or automatic—to improve air flow and regulate gas (CO₂) buildup.
• 🦠 Innovative Disinfection: UV treatment and air purification reduce pathogen load in advanced stores.

**Additionally:**

• 📦 Smart Bins enable regular inspection and easier removal of suspect tubers.
• 📊 Data Monitoring Systems: Real-time temperature, humidity, and CO₂ sensors connected to mobile or web apps.
