The cultivation of lavender (Lavandula angustifolia Mill (Lavande Fine)) and lavender hybrids (Lavandula angustifolia X Lavandula latifoliaI) is a traditional agricultural activity in the southeast of France.

In France and elsewhere, research has focused on (i) the selection of new varieties, (ii) the production of healthy plants, (iii) the identification of different phytoplasma strains and, more recently, (iv) several vector control approaches.
The objectives of the project are:
