Weeds and Weed Grasses in Root Crops

As the name already says, root crops require, alongside good crumb aeration, intensive suppression of the growth of weeds and weed grasses. With regard to species diversity and competitive pressure, the weed population is the greatest within the crop rotation. Because root crops are sown later than summer cereals, there is as a rule sufficient time to precede sowing with one to three harrow passes, which uproot the early- and medium-early germinating weeds and weed grasses. Where possible — for instance with fodder beet (*Beta vulgaris*), cabbage (*Brassica*), and others — transplanting from the seedbed can gain still more time, to keep even later-germinating weeds such as gallant soldier (*Galinsoga*), orache (*Atriplex*), and fat hen (*Chenopodium*) from the field. Root crops generally have a long juvenile period and therefore permit mechanical weed control with weeder harrow, hoe, and ridger to be continued up to row closure. Where necessary, the rows must be gone through once more by hand.
