Signage Ambroisie allows everyone to contribute to the fight against ragweed in France.

The pollen of ambrosia harms health. It only takes a few grains of pollen so that the first symptoms appear in people with allergies.

Ambrosia signaling allows you to signal the presence of this plant in a very simple and fast way. Your reports will be sent to the ambrosia reporting platform and transmitted instantly to the referent of the municipality concerned (if there is one) who will coordinate the actions to fight to eliminate ambrosia.

Remember to activate the GPS of your Smartphone!

The application also provides information on the recognition of ragweed, the areas reported and the allergic risk related to its pollen. Ambrosia reporting is an interactive platform for reporting ambrosia via several channels:

- A Smartphone Application

- A website www.signalement-ambroisie.fr

- An e-mail address [email protected]

- a telephone number 0 972 376 888

Reporting Ambroisie is financed by a mutual fund of the Regional Health Agencies, under the coordination of the General Secretariat of the Ministries in charge of Social Affairs.
