You have chosen the option guided diagnosis * . The procedure for identifying diseases in tomatoes is relatively straightforward. You will select from the menus progressively made available to you, on the left of the screen, the title that best corresponds to the fruits of your observations of diseased plants, in particular where the symptoms are located on the tomatoes and what their nature is, by specifying more and more the latter. If you do not have this information follow this link .

At the end of your journey through the menus, you will access a set of sections providing some general information on the last symptom chosen and proposing one or several possible causes associated with diagnostic arguments. All you have to do is consult these various causes and choose the one whose description and associated images best match your observations.

Once the disease has been identified, we suggest you consult a sheet in the section of the application Knowing and controlling pests and diseases , which provides an update on all the main knowledge available on the subject.

* We would like to draw your attention to the fact that this identification module has been designed to facilitate your diagnosis and not to do it for you. You are therefore responsible for the final identification.
