| 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 |

| Infestation with Cirsium arvense in organic cropping is an increasing problem in many parts of Europe. A very expansive root system and the ability to form new aerial shoots from root buds facilitate formation of dense patches only a few years after establishment. In the present study, repeated mowing during the first part of the growing season used in combination with a competitive crop is suggested as a control strategy, aiming at diminishing the regenerative capacity of C. arvense. In general, the results from our two experiments showed a linear relationship between the number of mowing passes and the aboveground biomass of C. arvense in the subsequent year. A comparison of the two regression lines within each experiment showed that in both experiments... |

| Infestation with Cirsium arvense in organic cropping is an increasing problem in many parts of Europe. Non-chemical management strategies against C. arvense based on cultivation tactics and/or different cutting regimes have acquired very little attention for years. This study presents results from four experiments, undertaken under organic growing conditions, on the effects of repeated mowing or hoeing during the first part of the growing season used in combination with competition from a suppressive crop (grass white-clover mixture and red clover). The strategies were mainly aimed at diminishing the regenerative capacity of C. arvense and effects were thus measured in the subsequent year in spring barley. In general, number of passes of mowing and hoeing... |
