Infestation with Cirsium arvense in organic cropping is an increasing problem in many parts of Europe. In the present study, repeated hoeing during the first part of the growing season is suggested as a mechanical control strategy, aiming at diminishing the regenerative capacity of C. arvense. Results showed a linear relationship between the number of hoeing passes and the aboveground biomass of C. arvense in the subsequent year. However, the strong effect on the biomass of C. arvense was not followed by an increased crop yield. A low initial density of C. arvense, which did not cause any measurable yield loss, most likely explains this

Summary translation

L’infestation des cultures bilogiques par le chardon des champs est un problème croissant en Europe. Dans cette étude, une stratégie de binages répétés durant la première partie de la période de croissance est proposée pour diminuer le potentiel de régénération du C. arvense. Une relation linéaire a été observée entre le nombre de passages de bineuse et la biomasse aérienne du chardon au cours de la campagne suivante. Cependant, l’effet important sur la biomasse de chardon n’a pas induit d’effet sur le rendement de la culture. Ce résultat est probablement lié à un faible niveau initial d’infestation par le chardon sur la parcelle d’essai, sans effet mesurable sur le rendement.
