AI Disease & Pest Identification

Identify any crop disease. In the field.

Seneroy AI's crop disease scanner helps Ghana farmers identify pests and diseases from visual symptoms — without needing to send samples to a lab or wait for an extension officer. Over 100 crop diseases and pests in an offline database, covering Ghana's most economically damaging threats.

Know your enemy. Act fast.

Disease and pest losses cost Ghana's farming sector billions of cedis annually. Fall Armyworm alone can cause 20–70% yield loss in maize if uncontrolled. Cocoa Black Pod destroys an estimated 30–40% of Ghana's potential cocoa output in high-pressure years. Cassava Mosaic Virus is endemic across the forest zone. Early identification and fast response is the difference between a manageable setback and a season-destroying outbreak.

The challenge is that most farmers cannot quickly identify what they are looking at. Similar symptoms — yellowing leaves, wilting, spots on pods — can mean completely different things requiring completely different treatments. Treating Fall Armyworm with the wrong chemical costs money and kills beneficial insects. Treating Cassava Mosaic (a virus) with fungicide is money wasted. Correct identification comes first.

Seneroy AI's disease scanner walks you through a symptom checklist and narrows the likely cause from 100+ possibilities to the 3 most probable diseases or pests for your crop, region, and current season. Lena AI then explains what to do about each one in plain language — chemical name, rate, timing, and safety precautions.

Ghana's biggest crop threats — in the database.

🐛
Fall Armyworm (FAW)
Ghana's most destructive maize pest since 2016. Identified by inverted Y on head capsule, square spots on abdomen. Control: Emamectin Benzoate 1.9EC into whorl. Scout weekly from week 2.
🦠
Cassava Mosaic Virus
Causes mosaic yellowing, leaf distortion, and stunting. Spread by whitefly. No chemical cure — remove infected plants, plant resistant varieties (TME 204, IITA TMS). Control whitefly population.
🍫
Cocoa Black Pod (Phytophthora)
Dark brown-black lesions on pods, spreading in humid conditions. Control: Metalaxyl-M + Copper (Ridomil Gold) spray every 3 weeks at pod formation. Remove and bury infected pods.
🔴
Cocoa Capsid Mirid
Sucking insect causing chestnut-brown lesions on stems and pods ("dieback"). Control: Chlorpyrifos or Cypermethrin spray. Two applications per season — at pod formation and harvest.
🌿
Anthracnose (Cashew & Mango)
Dark lesions on leaves, flowers, and nuts. Worst at high humidity during flowering. Control: Copper-based fungicide spray at flowering. Clean pruning tools between trees.
🪲
Stem Borer
Larvae bore into maize and sorghum stems causing "dead heart" in seedlings and broken tassels in mature plants. Control: Carbofuran granules in whorl at 2–3 weeks, or Chlorpyrifos spray.
🌾
Rice Yellow Mottle Virus
Yellow streaks and stunting in rice. Spread by beetles and contaminated tools. No chemical cure. Use certified disease-free seed, clean equipment, and resistant varieties.
🟡
Groundnut Rosette Virus
Causes severe stunting, chlorosis, and yield loss up to 100% in severe outbreaks. Spread by aphids. Control: Early planting, aphid management, resistant varieties (ICGV series).
🐚
Banana Weevil (Plantain)
Larvae tunnel through corm, causing plant collapse. Signs: yellowing, reduced bunch size, holes in corm when dug. Control: Pheromone traps, clean planting material, remove old stumps.

Not just crops. Livestock too.

The disease scanner extends to livestock. The Animal Health Library in Seneroy AI covers disease profiles for poultry (Newcastle Disease, Gumboro IBD, Avian Influenza), cattle (CBPP, FMD, Lumpy Skin), goats and sheep (PPR, CCPP), pigs, tilapia, catfish, rabbits, grasscutter, and bees — with urgency ratings, zoonotic flags, vaccination protocols, and withdrawal periods for any treatments used.

When the Decision Engine scores a livestock unit as High Risk, it automatically surfaces the top three most likely diseases from the health library — ranked by how closely the unit's symptoms match each disease profile. This is the same disease bridge that connects Lena's AI reasoning to the real-world treatment protocols your vet would recommend.
