The Pleumeur-Gautier testing ground station (22) has embarked on various tests of plant associations, such as leeks with coriander or green manures sown in the foot loops. Every 10 leek plants, a coriander stalk blooms. In an experimental plot of the Terre d'Essais station and for a Casdar project named Repulse, the flowering plants aim to "induce flight behavior for thrips and leafminers", explains Maxime Davy, engineer. seconded from CTIFL to the Pleumeur-Gautier station (22). The leek is cultivated there classically, notations are carried out regularly to "know the spatio-temporal dynamics" of the pests. Sticky blue plates are also placed in the plot, in order to count these insects in the boards associated with coriander or not. "There are a lot of factors to come into play, in particular cilantro must be managed, so as not to have any effect on the yield of the main crop and so that it does not go to seed."
