What the Plant Sickness Identifier Detects
Match what you see on your plant, or let the plant sickness identifier do it for you from a photo. From wilt to mold, the plant disease identifier checks the most common plant problems.
Yellow Leaves
Looks like: Leaves turn pale or yellow, often starting with the lower, older leaves.
Common causes: Overwatering, poor drainage, nitrogen deficiency, too little light or natural aging.
First step: Check the soil: if it is wet a few centimeters down, let it dry out before watering again.
Brown or Black Leaf Spots
Looks like: Round brown, black or yellow-ringed spots that spread across the leaf.
Common causes: Fungal leaf spot, bacterial leaf spot, black spot on roses or sunburn.
First step: Remove the worst leaves, water at the base and keep the foliage dry.
White Powder on Leaves (Powdery Mildew)
Looks like: A dusty white or gray coating on leaves and stems that wipes off.
Common causes: Powdery mildew, a fungus that loves humid air and poor airflow.
First step: Isolate the plant, improve airflow and cut off heavily coated leaves.
Wilt: Wilting and Drooping Leaves
Looks like: Leaves and stems go limp even though the plant was green yesterday.
Common causes: Underwatering, root rot, heat stress, transplant shock or wilt diseases (Fusarium, Verticillium).
First step: Feel the soil. Dry soil means water now; soggy soil points to root problems.
Root Rot and Mushy Stems
Looks like: Soft, dark stems at the soil line, a sour smell and brown, slimy roots.
Common causes: Waterlogged soil and fungi such as Pythium, Phytophthora or Fusarium.
First step: Unpot the plant, trim the rotten roots and repot in fresh, well-draining soil.
Pests: Aphids, Spider Mites, Mealybugs
Looks like: Sticky leaves, fine webbing, white cottony clusters or tiny moving dots.
Common causes: Sap-sucking insects that weaken the plant and spread viruses.
First step: Rinse the leaves, then treat with insecticidal soap or neem oil.
Mold on Plants and Soil
Looks like: White fuzzy mold on the soil surface or gray fuzz (botrytis) on flowers and leaves.
Common causes: Constantly damp soil, low light and stagnant air; gray mold is a fungal disease.
First step: Scrape off moldy topsoil, water less often and remove infected flowers.
Curling Leaves and Holes
Looks like: Leaves curl, pucker or have ragged holes and chewed edges.
Common causes: Pests, viral infections, heat, wind damage or caterpillars and slugs.
First step: Look under the leaves for insects and check whether the damage is spreading.
🍅 Tomato Disease Identifier: Spots, Yellow Leaves, Blight
Tomatoes get sick more often than almost any other garden plant. Photograph a spotted or yellowing tomato leaf and the plant disease identifier tells you which tomato disease it is and what to do.
Early Blight
Brown spots with dark rings like a target on the lower leaves, which then turn yellow and drop. Remove infected leaves and mulch to stop soil splashing onto the plant.
Late Blight
Large greasy, gray-green to brown patches on leaves and stems, white fuzz underneath in damp weather, brown rot on the fruit. Spreads fast: remove affected plants right away.
Septoria Leaf Spot
Many small round spots with gray centers and dark edges, starting on the oldest leaves. Prune the lower leaves, water at the base and keep the foliage dry.
Blossom End Rot and Leaf Curl
A dark sunken patch at the bottom of the fruit comes from uneven watering and calcium uptake; curled, crinkled leaves point to heat stress, herbicide drift or a virus.
How the Plant Disease Identifier Works
1. Photograph the Problem
Take a close-up of the sick leaves, stem or roots in daylight.
2. Get a Plant Diagnosis
The AI plant doctor identifies the plant and spots disease, pests or care mistakes.
3. Treat and Recover
Follow the treatment and care advice to bring your sick plant back to health.
Types of Plant Diseases and Problems
Most plant problems fall into one of six groups. The plant disease identifier checks all of them at once, so you do not need to guess whether it is a fungus, a pest or a watering mistake.
| Type | Examples | Typical signs |
|---|---|---|
| Fungal diseases | Powdery mildew, leaf spot, rust, gray mold, root rot | Spots, powdery or fuzzy coating, rotting |
| Bacterial diseases | Bacterial leaf spot, blight, soft rot | Water-soaked spots, slimy tissue, sudden wilting |
| Viral diseases | Mosaic virus, leaf curl virus | Mottled yellow-green patterns, distorted growth |
| Pests | Aphids, spider mites, mealybugs, scale, thrips | Sticky residue, webbing, holes, visible insects |
| Nutrient problems | Nitrogen, iron or magnesium deficiency | Yellowing between veins, pale new growth |
| Care and environment | Overwatering, underwatering, sunburn, cold damage | Wilting, crispy edges, brown patches |

Plant Sickness & Plant Disease Identifier FAQ
Our free sick plant app for iPhone works as a plant disease identifier: you take a photo, and it runs a plant diagnosis, names the likely disease or pest and gives treatment and care advice. It covers fungal, bacterial and viral diseases, pests, nutrient problems and watering mistakes.
Yes. This free plant disease identifier works right in your browser: upload a photo and it names the disease, pest or care problem. On iPhone, our free sick plant app adds unlimited checks and treatment advice.
Plant Detector is a free plant sickness identifier: upload a photo of the sick plant and it tells you the disease, pest or care problem in seconds, right in the browser. On iPhone, our free sick plant app adds unlimited checks and treatment advice.
A plant sickness identifier is a tool that looks at a photo of a sick plant and tells you what is wrong: a disease like wilt or powdery mildew, a pest like spider mites, or a care problem like overwatering. Plant Detector is a free plant sickness identifier you can use in the browser.
Yes. The plant disease identifier recognizes wilt and helps tell its causes apart: simple underwatering, root rot from soggy soil, heat stress, or wilt diseases such as Fusarium and Verticillium wilt that block water flow inside the stem.
Look at where the problem starts and what it looks like: yellow lower leaves usually mean watering issues, spots point to fungal or bacterial leaf spot, white powder is powdery mildew, and sticky leaves or webbing mean pests. The fastest way is to snap a photo with a plant doctor app and get a diagnosis in seconds.
Yes. AI plant diagnosis compares your photo with thousands of examples of diseased and healthy leaves. For the best result, photograph the damaged part up close in daylight, and add a second photo of the whole plant.
The most common cause is overwatering, followed by poor drainage, lack of light and nitrogen deficiency. If only the oldest leaves yellow slowly, it can be normal aging. A plant sickness identifier helps you tell these causes apart.
Fuzzy white mold on the soil surface is usually a harmless saprophytic fungus that grows when the soil stays wet. Scrape it off, let the soil dry between waterings and improve airflow. Gray fuzz on leaves or flowers is different: it is botrytis, a plant disease that needs the infected parts removed.
Take a close-up of a damaged tomato leaf in daylight, top and underside if you can, and upload it. The plant disease identifier recognizes the common tomato diseases: early blight, late blight, Septoria leaf spot, leaf curl and blossom end rot, and tells you how to treat them.
You do not need to install anything on Android: open this page in Chrome and the plant sickness identifier diagnoses plant problems from a photo for free. Our sick plant app itself is available on iPhone and iPad.
For common diseases and pests on houseplants and garden plants, an AI plant doctor is right most of the time when the photo is sharp and shows the symptoms clearly. For valuable crops or trees, confirm the diagnosis with a local extension service or plant clinic before using strong treatments.
