Combination of catch crops and perennial weed control is difficult
Weed control between rows of catch crops after harvest makes it possible to control perennial weeds while the catch crop is growing.
By establishing catch crops in connection with the last weed control in the row in a grain crop and weed control row in the stubble after harvest, it is possible to do mechanical weed control of the entire cultivated area during the growing season and at the same time to have vegetation.
Thistles (Sonchus and Cirsium) will be reduced by weed control between rows of catch crop after harvest, but only when weed control between crop rows has also been carried out. Common couch grass is not reduced significantly, but needs more vigorous weed control in the stubble
