  1. Control weeds without damaging other plants in conservation areas

    A replicated, controlled study in an arable field in Denmark (Graglia et al. 2006) found that increased mowing and hoeing frequency tended to reduce the amount of above ground creeping thistle Cirsium arvense biomass in the subsequent year (up to 73% compared to control). The presence of a suppressive crop (grass/white clover Trifolium repens mixture or red clover T. pratense) tended to further reduce creeping thistle. Differences in barley yield were only explained by the amount of creeping thistle biomass in one experiment, where the weed was most abundant. Four adjacent sub-fields, divided into four blocks were subject to a combination of cropping (grass/clover in half of the plots, spring barley with grass/clover undersown in half of the plots, spring barley with red clover undersown in half of the plots) and mechanical (0, 2, 4, 6 passes with a mower; 0, 3, 6 or 0, 1, 3, 5 passes with a hoe) treatments over a 3-year period (between 2000-2004). Heights and dry weights of above ground shoots of creeping thistle were obtained before harvest in the third year, as was barley yield.
