- in 3 companies producing and trading seeds of Cucurbita pepo, Cucumis sativus and Cucumis melo. Phytosanitary measures were implemented (destruction and incineration of plants, treatments against the virus vector, Bemisia tabaci),
- in 2 sites for fruit production of Cucurbita pepo (1 ha outdoor plot and a 640 m² growing tunnel). All plants in the affected plots were uprooted and destroyed after harvest. In 2023, the growers will have to carry out crop rotation and apply treatments against the vector.
