The Challenge: In Kenya’s potato-growing belts like Nyandarua and Nakuru, Bacterial Wilt (Brown Rot) is the single greatest threat. Once the soil is infested, traditional chemicals often fail because the bacteria live deep within the plant’s vascular system.
The Solution: The "Bio-Shield" Protocol Instead of trying to "cure" the disease after it appears, we use EcoRic to prime the plant's natural defenses through Induced Systemic Resistance (ISR).
Recommendations:
- Tuber Priming (Before Planting): Spray your seed tubers with an EcoRic solution (1L per ton) or soak them for 3-5 hours. This creates a biological barrier around the eyes of the potato, preventing pathogens from entering during the critical sprouting phase.
- Foliar Fortification: Spray the crop at a dose of 1–2 L/ha during the 3-5 leaf stage and again before hilling. This boosts the plant's internal immunity, making it more resistant to both bacterial wilt and early blight.
Economic ROI per Acre:
- Yield Increase: Systemic use of EcoRic on varieties like Shangi or BP808 increases yield by 20–25%.
- Cost Savings: Reduce mineral fertilizer (NPK/DAP) and expensive copper bactericides by 30%.
- Net Profit: A typical investment of KSH 4,000–6,000 in EcoRic can save a harvest worth KSH 100,000, delivering a return of 5x to 8x.
