Recommended Controls
All Weeds
Before establishing a mint planting, reduce perennial weeds
in the area to be planted with systemic broad-spectrum
herbicides and/or cultivation. For full-season weed control
consider combinations of dormant, in-season, and postharvest
herbicide applications.
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
Because mint is grown as a short-lived perennial crop, weed
management in preceding crops is important to reduce the
amount of weed seeds in the soil, and good weed control in
the planting year is especially important. Between-row
cultivation can be used in the first year before stolons and
rhizomes grow into fill in this space. Late winter or early
spring cultivation can be used to control winter annual weeds.
Pesticide
Aim EC (2) (carfentrazone) POST
| 0.5 to 1.92 fl. oz.
per acre Apply before crop emergence to emerged weeds less
up to 4 in. tall. Add 1 qt. COC (1% v/v) or 0.5 pt. NIS per 25
gal. of spray solution (0.25% v/v). REI: 12-hour. PHI: 5-day
HRAC 14.
Assure II (0.88EC) (quizalofop) POST
| 8-12 oz. per
acre. Add 1 qt. COC or 0.5 pt. NIS per 25 gal. of spray
solution. Apply to actively growing grass. Do not exceed 2
applications or 24 fl. oz. per acre per season. Applications
must be greater than 7 days apart. REI: 12-hour. PHI: 30-day.
HRAC 01.
Basagran (4) (bentazon) POST
| Use 4L formulations
at 1-2 pts. per acre and 5L formulations at 1.2-1.6 pt per acre.
Apply after mint and weeds have emerged. To control yellow
nutsedge and Canada thistle, repeat application 7-10 days
