Detecting crop disease for small farms

Smallholders often identify leaf disease too late for affordable treatment, losing yield and income.

Problem

Farmers lack extension officers nearby and misdiagnose fungal vs nutrient stress from phone photos shared in chat groups.

Scout fields visually, ask neighbors or agro-dealers, then purchase pesticides—often the wrong product.

Yield loss, unnecessary chemical use, and debt from failed harvests.

On-device vision models can suggest likely diseases with confidence and recommended integrated pest management steps.

Similar visual symptoms; needs local crop varieties and lighting robustness.

Wrong treatment advice; encouraging excess pesticide if not paired with IPM guidance.

Extension hotlines, paper ID guides, dealer advice.

Hotlines are overloaded; guides are hard to match in the field; dealers may push inventory.
