Plant.health's new feature Symptoms provides clearer and more actionable insights into plant health. Using thousands of phytosanitary expert-annotated photos, we've created 11 key symptoms, see table below.

Symptom	Description	Typical Cause(s)
Blight	Chlorosis, browning, and often rotting of plant tissues (leaves, twigs, branches, or flowers)	Pathogenic infection
Browning Leaf Tips	Dead, dried-out leaf tissue, most commonly located at leaf tips or leaf margins	Overwatering or uneven watering
Curled Leaves	Leaves tend to roll	Lack of water, pathogenic infection
Discoloration	Leaves turn pale green and yellow	Nutrient deficiencies (nitrogen, iron, magnesium, or potassium), under or over watering, low light, pests, viruses, or natural aging
Holes in the Leaves	Gaps or cuts	Insects or snails
Leaf Cuts	Typically straight cuts or light streaks on leaves	Human activity
Leaf Dieback	Whole leaves die, turn dark, and often appear wilted	Disease or age
Leaf Spots	Small dark spots on leaves	Bacterial infection
Pest Traces or Occurrence	Presence of insects or other pests or their products, such as mines (meandering tunnels), webs, eggs, or excrement	Insects or other pests
White Patches	Whitish or grayish coatings or spots on the surface of plants	Fungi
Wilted Leaves	Drooping leaves	Lack of water

In the API, you can set up this feature by using the parameter "symptoms":true.

The API returns heatmaps of all identified symptoms, highlighting the most affected plant areas. Additionally, there is a score for each of the symptoms indicating its severity and an overall defect score, giving a quick overview of the plant's health status.

Try this feature on the Plant.id demo. Here is an example (health assessment - Symptoms - Visualize symptoms).

We believe this feature will enable users to quickly and accurately diagnose plant issues, improving their understanding and ability to address underlying problems, and enhancing their overall experience.

Plant.health major expansion: from 90 to 500+ diseases

We’re rolling out a major upgrade to the Plant.Health disease detection model—built on a new architecture, trained on a much larger dataset, and backed by an expanded, multilingual knowledge base. The model now distinguishes 548 plant-health classes (up from 90) across insects, fungi, bacteria, and abiotic stresses—while maintaining overall accuracy.

Using LLMs for Descriptions of Plants, Insects, and Fungi

We tested LLMs to improve multilingual descriptions of plants, insects, and fungi where Wikipedia entries were inadequate. GPT-4o outperformed smaller models such as GPT-4o mini and Mistral Pixtral 12B, especially in grammar and factual accuracy. It performed better in widely spoken languages and common species. In the end, GPT-4o was used to generate descriptions in 28 languages, providing better coverage for the Kindwise API.

Summer 2024 Plant.id Model Update

The Plant.id model upgrade resulted in significant improvements in accuracy. It reached over 85% accuracy in the first response (TOP 1). The increase is greatest for European and North American plants, with 6.0% and 3.6%, respectively.

The Plant Identification Battle: GPT-4 vs. Plant.id

Multimodal Large Language models have recently made it possible to identify various objects from images, including plants. This became a competition for narrowly focused neural network models, such as that of Plant.id. Here we compare the accuracy of these models by focusing on the proportion of wrong answers.
