Manipulating vineyard weeds with herbicides

Vineyard weeds vary from location to location but often include a broad complex of 15 to 25 species. Most vineyard managers control weeds by applying herbicides or by plowing a strip down the crop row. Weeds between the rows are controlled by discing or mowing (mechanical or chemical) in a total weed control program. In some vineyards, annual or perennial grass or broadleaf cover crops are planted between the rows.
