USE RATES
Apply DuPont™ HARMONY® GT XP at 0.3 to 0.6 ounce per
acre to crop stubble after harvest. Use the 0.6 ounce per acre rate
when weed infestation is heavy and predominantly consists of
t
hose weeds listed under the "WEEDS PARTIALLY
C
ONTROLLED" section of this label or when application
timing and environmental conditions are marginal. (See the
"APPLICATION TIMING" section of this label for restriction
on planting intervals). HARMONY® GT XP should be applied
in combination with other suitable registered burndown
herbicides (See the "TANK MIXTURES" section of this label
for additional information).
Sequential treatments of HARMONY® GT XP may also be
made provided the total amount of HARMONY® GT XP
applied during one fallow/pre plant cropland season does not
exceed 1.0 ounce per acre.
TANK MIXTURES IN POST HARVEST
APPLICATIONS
HARMONY® GT XP may be used as a post harvest treatment
to crop stubble, and should be tank mixed with other herbicides
that are registered for use in fallow.
GENERAL USE AND APPLICATION
DIRECTIONS - ALL CROPS AND
USES
GROUND APPLICATION
For best performance, select nozzles and pressure that
deliver MEDIUM spray. Nozzles that deliver COARSE
spray droplets may be used to reduce drift, provided spray
volume is increased to maintain coverage on small weeds.
For optimal product performance and minimal spray drift,
adjust the spray boom to the lowest possible spray height
recommended in manufacturers’ specifications.
Overlaps or starting, stopping, slowing, and turning while
spraying may result in crop injury.
WHEAT, BARLEY, OAT, TRITICALE, POST-
HARVEST BURNDOWN, PRE-PLANT
BURNDOWN AND FALLOW:
For flat-fan nozzles, use a spray volume of at least 5 gal per
acre (GPA).
For flood nozzles on 30" spacings, use at least 10 GPA,
flood nozzles no larger than TK10 (or the equivalent), and a
pressure of at least 30 psi. For 40" nozzle spacings, use at
least 13 GPA; for 60" spacings use at least 20 GPA. It is
essential to overlap the nozzles 100% for all spacings.
"Raindrop RA" nozzles are not recommended for
HARMONY® GT XP herbicide applications, as weed
control performance may be reduced.
Use screens that are 50-mesh or larger.
CORN AND SO
YBEANS:
Broadcast Application
Ensure that equipment is set up to avoid applying an excessive
rate directly over the rows and into the corn plant whorl.
Overlaps or starting, stopping, slowing, and turning while
s
praying may result in crop injury.
Under heavy weed pressure or dense crop foliage, increase
minimum spray volume to 15-25 gal per acre.
Band Application
For band applications, use proportionately less spray mixture.
To avoid crop injury, carefully calibrate the band applicator to
n
ot exceed the labeled rate.
Carefully follow the manufacturer’s instructions for nozzle type
(flat fans), orientation, distance of nozzles from the crop and
weeds, spray volumes, calibration and spray pressure.
AERIAL APPLICATION
Do not apply during a temperature inversion, when winds
are gusty, or when conditions favor poor coverage and/or
off-target spray movement.
In wheat, barley, oats, triticale, post-harvest burndown, pre-
plant burndown and fallow use 2 to 5 gallons per acre; use
at least 3 gallons per acre in Idaho, Oregon and Utah.
In corn and soybeans, use a minimum of 5 gallons per acre.
When applying HARMONY® GT XP by air in areas
adjacent to sensitive crops, use solid stream nozzles oriented
straight back. Adjust the swath to avoid spray drift damage
to sensitive crops downwind and/or use ground equipment
to treat the border edge of fields. See the Spray Drift
Management section of this label.
SPRAY ADJUVANTS
Always include a spray adjuvant with applications of
HARMONY® GT XP. In addition to a spray adjuvant, an
ammonium nitrogen fertilizer may be used. Do not use low
rates of liquid nitrogen fertilizer solution as a substitute for
surfactant. Antifoaming agents may be used if needed.
Consult your Ag dealer or applicator, local DuPont fact
sheets and technical bulletins prior to using an adjuvant
system. If another herbicide is tank mixed with
HARMONY
® GT XP, select adjuvants authorized for use
with both products. Products must contain only EPA-
exempt ingredients (40 CFR 1001).
Nonionic Surfactant (NIS)
•
Apply 0.06 to 0.50% volume/volume (1/2 pt to 4 pt per
100 gal of spray solution).
•
Surfactant products must contain at least 60% nonionic
surfactant with a hydrophilic/lipophilic balance (HLB)
greater than 12. – See the "TANK MIXTURES" section of
this label for additional information..
Crop Oil Concentrate (COC) - Petroleum or Modified
Seed Oil (MSO)
•
Apply at 1% v/v (1 gal per 100 gal spray solution) or 2%
under arid conditions. MSO adjuvants may be used at
0.5% v/v if specified on local DuPont product literature or
service policies.
•
Oil adjuvants must contain at least 80% high quality,
petroleum (mineral) or modified vegetable seed oil with at
least 15% surfactant emulsifiers.
Special Adjuvant Types
•
Combination adjuvant products may be used at doses that
provide the required amount of NIS, COC, MSO and/or
• Use 10-25 gallons of water per acre.
