Cole crop weed control is very difficult because of the limited selection of registered herbicides and the many aggressive weeds (mustards, shepherd’s purse, galinsoga, nightshade). Growers must practice overall farm weed control (see “Weed Management” in the Pest Management section of this guide). Transplanted crops are easier than direct-seeded crops to keep weed-free because they are quicker to establish. In addition to the herbicides listed in Table 1 (Cole Crops (Broccoli, Brussels Sprouts, Cabbage, Cauliflower) Weed Control), effective, timely cultivation is critical in preventing weed losses.
