Sweet Corn - Weeds
Accent Q (54.5WDG) (nicosulfuron) POST
|
0.45-0.90 oz. per acre. Use 1 qt. of COC or 8 fl. oz. of NIS
per 25 gals. of spray solution. Apply broadcast or with drop
nozzles on corn up to 12 inches tall or up through 5 leaf
collars. For corn 12-18 inches tall use drop nozzles. Do not
apply to corn more than 18 inches tall or showing 6 leaf
collars or more. Cultivars differ in sensitivity to this
herbicide; get information on cultivars prior to use. Not
recommended for use on corn previously treated with
Counter or Thimet insecticides. REI: 4-hour. HRAC 02.
acetochlor + atrazine products (acetochlor, atrazine)
PRE
| Apply 2.2-3.4 qts. per acre Breakfree ATZ,
1.6 to 3 qts. per acre Breakfree ATZ Light or Keystone LA,
2.9-3.7 qts. per acre Degree Xtra, 2.5-5 qts. per acre FulTime,
1.8-3.3 qts. per acre Harness Xtra, 1.4-3 qts. per acre Harness
Extra 5.6L, or 2.2-3.4 qts. per acre Keystone. Do not apply
postemergence. Use lower rates on coarse soils with low
organic matter. Apply before planting and incorporate, or
apply after planting before sweet corn emerges. Do not apply
to light textured soils specified in the label where ground
water is at 30 ft. or less. REI: 12-hour. HRAC 15, HRAC 05.
RUP.
acetochlor products (acetochlor) PRE
| Apply
1.5-3 pts. per acre for Harness 7E, 1.5-3.75 pts. per acre for
Surpass 6.4EC, or 2-3 pts. per acre TopNotch 3.2M. Do not
apply postemergence. Use lower rates on coarse soils with
low organic matter. Apply before planting and incorporate, or
apply after planting but before sweet corn emerges. May be
mixed with atrazine or simazine. See label for details. Do not
apply to light textured soils specified in the label where
ground water is at 30 ft. or less. REI: 12-hour. HRAC 15.
Acuron (atrazine, mesotrione, s-metolachlor,
bicyclopyrone) PRE
| 2.5 qts. per acre on soil with
less than 3% organic matter; 3 qts. per acre on soil with more
than 3% organic matter. For control of most broadleaf and
grass weeds. Control may be reduced on soils with >10%
organic matter. Do not apply after sweet corn has emerged or
severe crop injury may occur. 18-month replant restriction for
all crops except corn types (no restrictions); small grains (4
months); dry beans, potato, and soybean (10 months).
Contains atrazine so state restrictions for atrazine apply. REI:
24-hour. PHI: 45-day for grazing or forage feeding, 60-day
for forage harvest. HRAC 05, HRAC 27, HRAC 15. RUP.
Aim EC (2) (carfentrazone) POST
| 0.5-2.0 fl. oz. per
acre. Apply to actively growing weeds up to 4 in. tall from
prior to planting up to V-14 stage. To reduce injury, use drop
nozzles to make applications in corn from V8-V14 stages or
apply with a hooded-sprayer to minimize application to the
280
whorl. Add 0.5 pt. NIS per 25 gal. of spray solution (0.25%
v/v). Do not exceed 2 fl. oz. per acre per season. For
burndown applications, consider tank-mixing with an
additional broad-spectrum herbicide such as glyphosate. REI:
12-hour. HRAC 14.
Anthem (2.15SE) (pyroxasulfone, fluthiacet-methyl)
POST PRE
| 2.5-6.5 fl. oz. per acre. Apply 4-13
fl. oz. of Anthem or 2-6.5 fl. oz. Anthem Maxx per acre.
Adjust rate based on soil organic matter and texture, and pre
or postemergence use, see label. Preplant surface applications
are not recommended for sweet corn. Apply post from crop
emergence through V4 growth stage. Add an adjuvant such as
a NIS, COC, or MSO for best activity. Before applying to
corn, confirm that your line has Anthem tolerance with your
seed company or supplier to avoid injury to sensitive lines.
Avoid postemergence application when crop foliage is wet or
prior to or after a rain because a crop injury can occur.
However, the crop will recover. Do not apply if crop is under
stress and do not irrigate within 4 hours of a postemergence
application. REI: 12-hour. PHI: 40-day. HRAC 15, HRAC
14.
Anthem ATZ (4.505) (atrazine, pyroxasulfone, fluthiacetmethyl)
POST PRE
| 1.5-4 pts. per acre. Adjust
rate based on soil organic matter and texture, and pre or
postemergence use, see label. Preplant surface applications
are not recommended for sweet corn. Apply post from crop
emergence through V4 growth stage. Add an adjuvant such as
a NIS, COC, or MSO. Before applying to corn, confirm that
your line has Anthem selectivity with your seed company or
supplier to avoid injury to sensitive lines. Avoid
postemergence application when crop foliage is wet or prior
to or after a rain because a crop response can occur.
However, the crop will recover. Do not apply if crop is under
stress and do not irrigate within 4 hours of a postemergence
application. REI: 12-hour. PHI: 45-day. HRAC 05, HRAC
15, HRAC 14. RUP.
atrazine products (atrazine) POST PRE
|
Apply 4L formulations at 1-2 qts. per acre and 90W
formulations at 1.1-2.2 lbs. per acre. To control small,
emerged broadleaves, include COC. Apply before planting
and incorporate, after planting but before corn emerges, or
after emergence but before corn is 12 inches tall. Many
atrazine products are available. See labels for details. REI:
12-hour. HRAC 05. RUP.
Basagran (4) (bentazon) POST
| Use 4L formulations
at 1.5-2 pt. per acre and 5L formulations at 1.2 to 1.6 pts. per
acre. Add 1 qt. of COC per 25 gals. spray solution (1% v/v).
Apply to small weeds. Also controls nutsedge. Do not apply
to corn that is stressed because injury may result. Combine
with atrazine to broaden weed control spectrum. Do not
