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.
