Cole Crops and Brassica Leafy Greens – Weeds Reviewed by Stephen Meyers, Ben Phillips – Sept 2021 Recommended Controls All Weeds Cole crops are cool-season plants, but are nearly always started as transplants. When growers transplant cole crops into plastic mulch, no herbicides are labeled for use under the plastic because of the risk of damaging the crop. Early season plantings into cool soils are at greater risk of herbicide injury. There are several herbicides labeled for the control of weeds preemergence, applied before cole crops are transplanted, or directed between the rows only after transplanting. For specific weeds controlled by each herbicide, check the Relative Effectiveness of Herbicides for Vegetable Crops table. Rates provided in the recommendations below are given for overall coverage. For a banded treatment, reduce amounts according to the portion of acre treated. Non-Pesticide Broccoli, Brussels sprouts, Cabbage, Cauliflower, Collards, Kale, Kohlrabi, Mustard Greens, Turnip Greens | Design bed and row spacing to match equipment that will be used and other crops with similar space requirements. A stale seedbed can be prepared prior to transplanting with flame weeding or very shallow cultivation to control emerged weeds, instead of herbicides. Mulches provide good weed control when planted into, when used for between row spaces, or in combination in-row and between-row. Materials include landscape cloth, plastic, biodegradeable plastic, or straw applied before weeds emerge. Weeds between beds and along the edges of beds can be controlled with a combination of cultivation, mowing, or hand hoeing/pulling. Weeds along the edge of the mulches can be a particular challenge to avoid ripping the mulch. Pesticide Aim EC (2) (carfentrazone) POST Broccoli, Brussels sprouts, Cabbage, Cauliflower, Collards, Kale, Kohlrabi, Mustard Greens, Turnip Greens | Apply with hooded sprayers as a directed application between crop rows. Use COC or NIS. Weeds must be actively growing and less than 4 inches tall. Do not allow spray to contact crop. Do not exceed 6.1 fl. oz. per acre per season. REI: 12-hour. HRAC 14.
