Crop Disease DetectionSolutions
Let a farmer or field officer photograph a leaf and get a likely diagnosis with a confidence level, plain-language next steps, and a route to a human agronomist.
Crop Disease Detection Solutions: what the work involves
By the time a farmer notices yellowing leaves or curled tips, the problem may already be spreading across the field. Agriculture officers cover huge areas, advice arrives late, and pesticide dealers often become the default diagnosticians. A wrong guess means money spent on the wrong spray, a damaged harvest, and sometimes resistance that makes the next season harder.
DevKey builds image-based diagnosis tools around the crops and diseases that matter in your region, whether that is wheat rust, cotton leaf curl or citrus canker. We collect and label photographs with agronomists, train and test a vision model on field conditions rather than lab pictures, and wrap it in a simple phone app or messaging flow. The reply gives the likely issue, how sure the model is, and recommended actions in Urdu or English, and uncertain cases go to an expert.
Core features
Photo capture guidance
The app shows how to frame a leaf, avoid shadows and include healthy tissue for comparison, which improves results more than model tweaks.
Crop-specific models
Separate classifiers are trained for each crop and growth stage you support, reducing confusion between look-alike symptoms.
Confidence and alternatives
Results list the top possibilities with scores, and low-confidence images are never presented as a firm diagnosis.
Local-language advice
Recommended actions, from isolating plants to scouting neighbours, are written in Urdu or regional languages with simple wording.
Expert escalation
Unclear or high-impact cases are forwarded with the photo, location and crop details to an agronomist who replies inside the same thread.
Outbreak mapping
Anonymised detections with location and date build a heat map that helps officers spot spreading disease early.
What we get right before launch
Field images differ from clean datasets
Public datasets use tidy, well-lit leaves. Real photos have dust, mixed symptoms and poor cameras, so we gather local images, validate with agronomists, and report performance on unseen farms.
Advice has agricultural and chemical risk
A wrong recommendation can waste a crop or misuse chemicals. The tool suggests scouting and approved practices, avoids specific dosage claims unless an expert signs them off, and displays limitations clearly.
Connectivity and devices
Many farms have weak signal and low-cost phones. We design for offline-capable on-device models or compressed uploads, and queue results for when a connection returns.

Common questions, answered
How accurate is disease detection from a photo?
It depends on the crop, disease and photo quality, so we avoid a single claim. We test on photos from your region, report results per disease, and show confidence with every answer so users know when to seek an expert.
Which crops can you cover?
Common field and orchard crops are feasible if enough labelled images exist. Rare crops or diseases with few examples are harder. During discovery we check data availability and suggest a realistic starting set.
Can farmers use it on WhatsApp?
Yes. A farmer sends a photo to a business number and receives a reply with the likely issue and advice. This avoids app installs, though an app gives better capture guidance and offline options.
Who labels the training images?
Agronomists or trained field staff, using a labelling tool with agreed guidelines. Label quality drives model quality, so we spot-check for disagreement and refine categories before heavy training.
