Real Farmer Stories
Marie, Kayanza, Burundi (Cassava): “I lost almost everything to CBSD two years ago. Now I check my plants weekly with the WhatsApp bot. Last month it caught CMD early on three plants. The rest of my field is healthy.”
Grace, Western Province, Rwanda (Beans): “I cannot read well. I use voice notes in Kinyarwanda. The bot sends me voice replies. It told me my beans had angular leaf spot. Best bean harvest in five years.”
Why WhatsApp AI Beats Traditional Extension Services
Traditional extension: 1 worker per 5,000 farmers, visits every 2-6 months, English or French only.
WhatsApp AI: Available 24/7, responds in 30 seconds, multiple local languages, voice input/output, free or near-free.
This is a force multiplier that makes every extension worker 10X more effective. Learn more about how AI is revolutionizing farming in Africa.
Best Practices for Photo Quality
- Natural daylight (overcast days are best)
- Close to the leaf (fill the frame)
- Focus on damage (spots, holes, curling)
- Include a healthy leaf for comparison
- Hold steady
- Clean water droplets off leaves
Following these steps pushes diagnosis accuracy from 70% to 95%. Discover the complete guide to AI techniques that increase yield.
