Celery - Weeds

Recommended Controls
All Weeds
Celery is nearly always started as transplants. Early season
plantings in cool soils are at greater risk of herbicide injury.
There are several herbicides labeled for the control of weeds
preemergence, applied before celery is 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
Weed control in celery often relies heavily on cultivation and
hand-weeding for full season weed control. These operations
are most efficient when planting arrangement is designed
with weed control in mind and is designed to work with
available weed control equipment. Specialized weeding
equipment for celery includes basket weeders, narrow-bladed
hoes, finger weeders, and others. A stale seedbed can be
prepared prior to transplanting with flame weeding or very
shallow cultivation to control emerged weeds, instead of
herbicides.
Pesticide
Caparol 4L (prometryn) POST PRE

per acre. Make 1 or 2 applications 2-6 weeks after
transplanting but before weeds are 2 inches tall. Do not
