Diseases and pests identifcation

We are delighted to introduce a new feature in the Pl@ntNet application: the ability to identify plant diseases and pests from images. This first version aims to help users detect visible symptoms caused by common diseases or pests on a limited set of plant species.

By uploading photos showing signs of disease or infestation (spots on leaves, discoloration, deformations, or the presence of insects), users can receive preliminary suggestions about potential issues affecting the plant. Up to four photos can be sent; do not hesitate to take several photos of the signs of disease to improve the results.

While it is intended to grow and improve over time, it already constitutes a solid basis for supporting users in observing and understanding plant health. New diseases and pathogens, as well as new plant species, will be gradually added.

Disease identification results should be considered as informative advice, and not as a professional diagnosis, and are not intended to provide information on treatments (legally, this often depends on the governments of each country).

How can I access this new feature?

Identification of diseases and pests is available to everyone:

• on the website: https://identify.plantnet.org/diseases-and-pests

• on the mobile application (v3.26 minimum): by choosing the “Diseases and pests” flora in the “Specific floras” sub-menu

Disease observation contributions are currently very limited. If you are a professional in certain diseases and want to improve identification performance, please fill out the following form: https://forms.gle/BYH7WC9d8eJEm3dk9. Please feel free to detail your skills and profession so that we can respond to your request as quickly as possible, usually within 3 working days.

Going further

Help us cover more species: share your datasets!

If you are an expert Pl@ntNet user and have access to high-quality images showing plant diseases or pests (with reliable annotations), we would love to receive your help!

The contribution of these datasets can significantly improve the accuracy and coverage of our new disease identification feature. If you wish to share data or collaborate, please do not hesitate to contact us (by mentioning it in the comment field of the form) - we are delighted to co-build this feature with the community.

Explore observations of diseased plants

With this new feature, Pl@ntNet users will also be able to explore community observations of plants affected by various diseases and pests. These real-world examples, provided by other users and institutes, provide valuable insights into how different symptoms appear on specific species.

Whether you are looking to identify a problem or learn more about plant health, this growing collection of annotated images will help you recognize and compare visible signs of stress in plants.

Identify plants affected by diseases or pests

In addition to searching for observations, this feature allows you to identify specific diseases and pests directly from your own images.

By uploading a photo that clearly shows symptoms - such as spots, wilting, discoloration, or the presence of insects - Pl@ntNet will analyze the image and suggest possible causes. These suggestions are based on visual similarities to verified cases in our database and aim to help you quickly understand what may be affecting the plant.

Disease identification is available at the following address: identify.plantnet.org/diseases-and-pests and works almost exactly like the classic Pl@ntNet identification you are used to. Pl@ntNet also suggests the different host species for the diseases in question.

For now, disease identification cannot be shared on the platform like regular plant observations to prevent potential identification errors from spreading in our datasets (unless your profession has led you to contact us, see above).

Annotate existing plant observations with diseases

Once the disease or pest is selected, it annotates the plant observation with the disease or pest.

If you recognize symptoms on an image or if you know the specific problem affecting the plant, you can add or suggest annotations to enrich the database.

As mentioned previously and in order to improve identification performance, only a small number of users can contribute to these annotated observations. These contributions are essential for improving the accuracy of the identification feature and building a more comprehensive resource for the entire Pl@ntNet community.

Each image of an observation can receive a set of annotations. To annotate an image, select “Phytopathogens” annotations in the Annotations section next to the image and search for a specific value. If the disease you identify on your image is not in the list and you have more than 10 images illustrating it, please contact us here.

Research effort behind this feature

This new disease and pest identification feature is the result of ongoing research on phytosanitary diagnosis using computer vision and deep learning techniques. It builds on recent advances in image-based plant pathology and benefits from expert-created datasets to train and evaluate our models.

This collaboration between science and citizen observation is at the heart of Pl@ntNet’s mission: transforming collective intelligence into actionable tools for monitoring biodiversity and plant health.

We especially thank the participation of EPPO, INRAE, Cirad, and IRD.
