In the fast-moving world of agriculture, timing is everything. A few days can mean the difference between a healthy harvest and devastating crop loss. This is the story of how one farmer used Virtual Agronomist to detect a disease outbreak before government authorities even announced it. This is the proof that AI-powered agronomy isn’t just convenient; it’s transformative.
During one of his usual morning inspections on his small maize field in Lilongwe, Malawi, Paul Chunga noticed something troubling on his leaves. He pulled out his phone, opened WhatsApp, and messaged Virtual Agronomist. Within minutes, he had his answer: Downy Mildew.
The diagnosis came with comprehensive management recommendations, including crop rotation strategies, certified seed selection, drainage improvements, and specific fungicidal treatments like metalaxyl and mefenoxam. But the real story was just beginning. A day later, the Ministry of Agriculture, Irrigation and Water Development issued an official announcement: a downy mildew outbreak was affecting the region.

This wasn’t just a lucky guess. This was precision agriculture in action, demonstrating three critical advantages that Virtual Agronomist brings to African farmers:
1. Early Detection Saves Crops
Usually, by the time official outbreak announcements are made, the disease may have spread significantly. Paul had already identified the problem in his field and knew exactly what actions to take. While others were just learning about the threat, he was already implementing control measures, potentially saving his entire harvest.
2. Expert Knowledge, Instant Access
Traditional extension services are stretched thin across Africa. Waiting for an agronomist visit can take days or weeks, and for many smallholder farmers, such visits might never come at all. Virtual Agronomist delivers the same expertise instantly, via a platform farmers already use: WhatsApp. No apps to download, no training required, no waiting.
3. Actionable Intelligence, Not Just Information
Virtual Agronomist doesn’t stop at diagnosis. It provides tailored, science-backed recommendations specific to each farmer’s situation. From preventive measures to chemical treatments, from cultural practices to timing adjustments, farmers receive a complete action plan they can implement immediately.
The Science Behind the Speed
Virtual Agronomist’s diagnostic capabilities are powered by a combination of cutting-edge technologies:
Image-based Pest and Disease Recognition: Our AI analyzes crop symptoms and maps them to an extensive library of plant diseases and disorders to find the closest match.
iSDAsoil Integration: With access to Africa’s first field-level soil map providing 20+ soil properties at 30-meter resolution, Virtual Agronomist understands the environmental context of each field.
Local Climate Data: Weather patterns, seasonal conditions, and regional disease pressure all factor into our recommendations.
Continuous Learning: Every interaction makes our system smarter, helping us identify patterns and outbreaks even faster.
Since launching in February 2024, Virtual Agronomist has delivered agronomic advisories to over 250,000 farmers across seven African countries, covering 24 crops. The results speak for themselves:
- 50% average yield increase across crops
- Coverage in 7 countries and counting
- 24 crops supported
- Hyperlocal expert advice
- Instant diagnosis via WhatsApp
But numbers only tell part of the story. The real impact is farmers like Paul who now have the tools to protect their livelihoods, feed their families, and build resilient futures. This technology isn’t replacing human expertise, it’s democratising it. It’s putting decades of agronomic knowledge into the hands of every farmer, regardless of their location, resources, or connections.
As we work toward our goal of reaching 10 million African farmers by 2030, stories like these remind us why this work matters. Expert advice should be available to every farmer, not just those with access to traditional extension services. Technology should serve those who need it most and African agriculture should lead the world in innovation, not follow it.
