ENVIRONMENTAL HAZARDS
DO NOT apply directly to water, to areas where surface water is present or to intertidal areas below the
mean high water mark. DO NOT contaminate water when disposing of equipment washwaters or rinsate.
DO NOT apply where/when conditions could favor runoff.
Groundwater Advisory
Nicosulfuron is known to leach through soil into groundwater under certain conditions as a result of label
use. This chemical may leach into groundwater if used in areas where soils are permeable, particularly
where the water table is shallow.
Surface Water Advisory
This product may impact surface water quality due to runoff of rainwater. This is especially true for poorly
draining soils and soils with shallow ground water. This product is classified as having high potential for
reaching surface water via runoff for several months or more after application. A level, well-maintained
vegetative buffer strip between areas to which this product is applied and surface water features such as
ponds, streams, and springs will reduce the potential loading of this product from runoff water and
sediment. Runoff of this product will be greatly reduced by avoiding applications when rainfall or irrigation
is expected to occur within 48 hours.
Windblown Soil Particles Advisory
This product has the potential to move off-site due to wind erosion. Soils that are subject to wind erosion
usually have a high silt and/or fine to very fine sand fractions and low organic matter content. Other
factors which can affects the movement of windblown soil include the intensity and direction of prevailing
winds, vegetative cover, site slope, rainfall, and drainage patterns. Avoid applying this product if
prevailing local conditions may be expected to result in off-site movement.
Non-target Organism Advisory
This product is toxic to plants and may adversely impact the forage and habitat of non-target organisms,
including pollinators, in areas adjacent to the treated area. Protect the forage and habitat of non-target
organisms by minimizing spray drift. For further guidance and instructions on how to minimize spray drift,
refer to the Spray Drift Management section of this label.
DIRECTIONS FOR USE
It is a violation of federal law to use this product in a manner inconsistent with its labeling.
DO NOT apply this product in a way that will contact workers or other persons, either directly or through
drift. Only protected handlers may be in the area during application. For any requirements specific to your
State or Tribe, consult the agency responsible for pesticide regulation.
Accent Q herbicide, also referred to below as Accent Q, must be used only in accordance with
instructions on this label, or as otherwise permitted by FIFRA. Always read the entire label, including the
Limitation of Warranty and Liability.
USER SAFETY RECOMMENDATIONS
USERS SHOULD: Remove clothing/PPE immediately if pesticide gets inside. Then wash thoroughly
and put on clean clothing. Remove PPE immediately after handling this product. Wash the outside of
gloves before removing. As soon as possible, wash thoroughly and change into clean clothing.

PRODUCT INFORMATION
Accent Q herbicide is a water-dispersible granule used at a rate of 0.45 - 1.8 ounces (0.015 - 0.061 lb ai)
per acre for selective postemergence grass weed control in field corn grown for grain, seed or silage,
popcorn and sweet corn.
Accent Q can be tank mixed with a variety of herbicides to improve burndown and for residual control.
Accent Q provides weed control via foliar absorption. Accent Q only controls those weeds that have
emerged. For later-emerging weeds, a second application or a timely cultivation is required.
BIOLOGICAL ACTIVITY
Accent Q provides best results when applied to young, actively growing weeds. Applications made during
warm, moist conditions (70°F or more) and adequate soil moisture both before and after application
maximizes performance.
The degree and duration of control depend on spray coverage, weed spectrum, weed size, growing
conditions before and after treatment, soil moisture, and adjuvant selection.
Treating weeds that exceed maximum label height or that are under stress may result in incomplete
control. Poor weed control or crop injury may result from applications made to plants under stress from:
 abnormally hot or cold weather
 environmental conditions including drought, water-saturated soils, hail damage or frost
 disease, insect or nematode injury
 prior herbicide or carryover from a previous years herbicide application
Severe stress from conditions preceding or immediately following application may also result in crop injury
or poor weed control. Stress affects all weeds, but especially weeds including woolly cupgrass, green and
yellow foxtail, and wild proso millet. If the corn or grass weeds are under stress, delay application until
stress passes and both weeds and corn resume active growth.
Accent Q rapidly inhibits the growth of susceptible weeds, reducing weed competition within as little as 6
hours after application. Susceptible plants are controlled in 721 days.
Accent Q is rainfast in 4 hours.

V93 / Accent® Q / Amendment / 11-04-2024 Page 12
 DO NOT use on lawns, walks, driveways, tennis courts. Prevent drift of spray to desirable plants.
 DO NOT contaminate any body of water.
 DO NOT apply this product through any type of irrigation system.
PRECAUTIONS
Accent Q may interact with certain insecticides previously applied to the crop. Crop response varies with
corn type, insecticide used, insecticide application methods and soil type.
Accent Q may be applied to corn previously treated with chlorethoxyfos + bifenthrin, tebupirimphos +
cyfluthrin, tefluthrin insecticides or other non-organophosphate soil insecticides regardless of soil type.
Crop injury may occur following an application of Accent Q if there is a prolonged period of cold weather
and/or in conjunction with wet soils.
Dry, dusty field conditions may result in reduced control in wheel track areas.
Prevent drift or spray onto desirable plants.
Thoroughly clean application equipment immediately after use (See Sprayer Cleanup section of this
label).
For all application systems, use 50-mesh or larger strainer screens.
WEED RESISTANCE MANAGEMENT
Accent Q contains nicosulfuron and is a Group 2 herbicide based on the mode of action classification of
the Weed Science Society of America. Any weed population may contain or develop plants naturally
resistant to nicosulfuron and other Group 2 herbicides. The resistant biotypes may dominate the weed
population if these herbicides are used repeatedly in the same field. Appropriate resistance-management
strategies must be followed.
To delay herbicide resistance take one or more of the following steps:
 Rotate the use of nicosulfuron or other Group 2 herbicides within a growing season sequence or
among growing seasons with different herbicide groups that control the same weeds in a field.
Use burndown herbicides, soil-applied herbicides, and sequential applications utilizing other
modes of action.
 Use tank mixtures with herbicides from a different group if such use is permitted; where
information on resistance in target weed species is available, use the less resistance-prone
partner at a rate that will control the target weed(s) equally as well as the more resistance-prone
partner. Consult your local extension service or certified crop advisor if you are unsure as to
which active ingredient is currently less prone to resistance.
 Adopt an integrated weed-management program for herbicide use that includes scouting and
uses historical information related to herbicide use and crop rotation, and that considers tillage (or
other mechanical control methods), cultural (e.g., higher crop seeding rates; precision fertilizer
application method and timing to favor the crop and not the weeds), biological (weed-competitive
crops or varieties) and other management practices.
 Apply full rates of this product for the most difficult to control weed in the field at the specified size
(ideally 4 inches or less).
 Use a broad spectrum soil-applied herbicide with other herbicides modes of action as a
foundation for an effective weed control program.
 Scout before and after herbicide application to monitor weed populations for early signs of
resistance development. Indicators of possible herbicide resistance include:
V93 / Accent® Q / Amendment / 11-04-2024 Page 13
1. failure to control a weed species normally controlled by the herbicide at the dose applied,
especially if control is achieved on adjacent weeds;
2. a spreading patch of non-controlled pl ants of a particular weed species;
3. surviving plants mixed with controlled individuals of the same species. If resistance is
suspected, prevent weed seed production in the affected area by an alternative herbicide
from a different group or by a mechanical method including hoeing or tillage. Prevent
movement of resistant weed seeds to other fields by cleaning harvesting and tillage
equipment when moving between fields, and planting clean seed.
 If a weed pest population continues to progress or resistance is suspected after treatment with
this product, discontinue use of this product, and switch to another management strategy or
herbicide with a different mode of action, if available.
 Contact your local extension specialist or certified crop advisors for additional pesticide
resistance-management and/or integrated weed-management recommendations for specific
crops and weed biotypes.
For further information or to report suspected resistance, contact Corteva Agriscience, LLC at 800-258-
3033.
INTEGRATED PEST MANAGEMENT
This product may be used as part of an Integrated Pest Management (IPM) program that can include
biological, cultural, and genetic practices aimed at preventing economic pest damage. IPM principles and
practices include field scouting or other detection methods, correct target pest identification, population
monitoring, and treating when target pest populations reach locally determined action thresholds. Consult
your state cooperative extension service, professional consultant or other qualified authorities to
determine appropriate action treatment threshold levels for treating specific pest / crop systems in your
area.
MANDATORY SPRAY DRIFT MANAGEMENT
Aerial Applications:
 DO NOT release spray at a height greater than 10 feet above the vegetative canopy, unless a greate
application height is necessary for pilot safety.
 For applications prior to the emergence of crop s and target weeds, applicators are required to use a
Coarse or coarser droplet size (ASABE S572.1).
 For all other applications, applicat ors are required to use a Medium or coarser droplet size (ASABE
S572.1).
 The boom length must not exceed 65% of the wi ngspan for airplanes or 75% of the rotor blade
diameter for helicopters.
 Applicators must use one-half swath displacem ent upwind at the downwind edge of the field.
 Nozzles must be oriented so the spray is directed toward the back of the aircraft.
 DO NOT apply when wind speeds exceed 10 miles per hour at the application site.
 DO NOT apply during temperature inversions.
Ground Boom Applications:
 Apply with the nozzle height recommended by the manufacturer, but no more than 3 feet above the
ground or crop canopy.
 For applications prior to the emergence of crops and target weeds, applicators are required to use a
Coarse or coarser droplet size (ASABE S572.1).
 For all other applications, applicators are require d to use a Medium or coarser droplet size
(ASABE S572.1).
 DO NOT apply when wind speeds exceed 10 miles per hour at the application site.
 DO NOT apply during temperature inversions.

SPRAY DRIFT ADVISORIES
THE APPLICATOR IS RESPONSIBLE FOR AVOIDING OFF-SITE SPRAY DRIFT. BE AWARE OF NEARBY
NON-TARGET SITES AND ENVIRONMENTAL CONDITIONS.
IMPORTANCE OF DROPLET SIZE
An effective way to reduce spray drift is to apply large droplets. Use the largest droplets that provide target
pest control. While applying larger droplets will reduce spray drift, the potential for drift will be greater if
applications are made improperly or under unfavorable environmental conditions.
Controlling Droplet Size Ground Boom
 Volume - Increasing the spray volume so that larger droplets are produced will reduce spray drift. Use
the highest practical spray volume for the application. If a greater spray volume is needed, consider
using a nozzle with a higher flow rate.
 Pressure - Use the lowest spray pressure recommended for the nozzle to produce the target spray
volume and droplet size.
 Spray Nozzle - Use a spray nozzle that is designed for the intended application. Consider using
nozzles designed to reduce drift.
Controlling Droplet Size Aircraft
 Adjust Nozzles - Follow nozzle manufacturers recommendations for setting up nozzles. Generally, to
reduce fine droplets, nozzles should be oriented parallel with the airflow in flight.
BOOM HEIGHT Ground Boom
Use the lowest boom height that is compatible with the spray nozzles that will provide uniform coverage. For
ground equipment, the boom should remain level with the crop and have minimal bounce.
RELEASE HEIGHT - Aircraft
Higher release heights increase the potential for spray drift. When applying aerially to crops, DO NOT release
spray at a height greater than 10 feet above the crop canopy, unless a greater application height is necessary
for pilot safety.
SHIELDED SPRAYERS
Shielding the boom or individual nozzles can reduce spray drift. Consider using shielded sprayers. Verify that
the shields are not interfering with the uniform deposition of the spray on the target area.
TEMPERATURE AND HUMIDITY
When making applications in hot and dry conditions, use larger droplets to reduce effects of evaporation.
TEMPERATURE INVERSIONS
Drift potential is high during a temperature inversion. Temperature inversions are characterized by increasing
temperature with altitude and are common on nights with limited cloud cover and light to no wind. The
presence of an inversion can be indicated by ground fog or by the movement of smoke from a ground source
or an aircraft smoke generator. Smoke that layers and moves laterally in a concentrated cloud (under low wind
conditions) indicates an inversion, while smoke that moves upward and rapidly dissipates indicates good
vertical air mixing. Avoid applications during temperature inversions.
WIND
Drift potential generally increases with wind speed. AVOID APPLICATIONS DURING GUSTY WIND
CONDITIONS.
 Applicators need to be familiar with local wind pa tterns and terrain that could affect spray drift.
DRIFT CONTROL ADDITIVES
Using product compatible drift control additives can reduce drift potential. When a drift control additive is
V93 / Accent® Q / Amendment / 11-04-2024 Page 15
used, read and carefully observe cautionary statements and all other information on the additives label. If
using an additive that increases viscosity, ensure that the nozzles and other application equipment will
function properly with a viscous spray solution. Preferred drift control additives have been certified by the
Chemical Producers and Distributors Association (CPDA).
FIELD CORN GROWN FOR GRAIN OR SILAGE
Timing to Crop
Accent Q is registered for use on field corn, high lysine, waxy, white or other food grade corn hybrids.
Accent Q may be broadcast to corn up to 20" tall (free standing) or that is exhibiting up to and including 6
leaf collars (V6), whichever is more restrictive.
While Accent Q has a wide application window, research has shown best results are obtained when
applications are made early postemergence when corn and weeds are small. Target applications to corn
that is less than 12” tall for best overall performance.
Timing to Weeds
Apply Accent Q when grasses are young and actively growing, but before they exceed the sizes indicated
in “Weeds Controlled” table with 0.9 ounces (0.031 lb ai) Accent Q per acre. Treat heavy infestations of
weeds before they become too competitive with the crop, especially where soil moisture and/or fertility
are limited. Accent Q provides weed control via foliar absorption. Accent Q only controls those weeds that
have emerged. For later-emerging weeds, a second application or a timely cultivation is required.
Applications made to weeds larger than the size indicated on this label or to weeds under stress may
result in unsatisfactory control. Refer to LATE APPLICATIONS.
On glyphosate-resistant corn, glyphosate products, including ABUNDIT
® Edge, may be applied with
Accent Q after weeds emerge but before they reach the maximum size listed on the glyphosate herbicide
label.
On glufosinate-resistant corn, glufosinate products may be applied with Accent Q after weeds emerge but
before they reach the maximum size listed on the glufosinate herbicide label.
LATE APPLICATIONS IN FIELD CORN GROWN FOR GRAIN OR SILAGE
Accent Q may be applied to field corn as a directed postemergence application on corn that is taller than
20” or which has more than 6 collars (whichever occurs first).
 For corn 20” to 36” tall, apply Accent Q with drop nozzles only and avoid spraying into the whorl
of cornstalks.
 DO NOT apply to corn that is taller than 36" or that exhibits 10 or more collars (V10), whichever is
most restrictive.
Applications made to weeds larger than those listed on this label may vary from complete control to
suppression. Level of control will depend on the weed species, stage of growth, and environmental
conditions.
Choices must be made between the risks that arise from applications made beyond the proper time for
Accent Q use and the effects of season long grass competition and/or harvest complications. These
choices must balance risks from improperly timed Accent Q use that include, but are not limited to:
 Yield loss due to competition: Research indica tes competition from foxtail exceeding 4 inches in
height may reduce corn yields. Applications to foxtail and other annual grasses that exceed the sizes
stated on the label increases the risk of yield loss due to prolonged competition with the crop even
though control may be acceptable.
V93 / Accent® Q / Amendment / 11-04-2024 Page 16
 Incomplete control of grasses beyond labeled size : Applications to grasses that exceed the labeled
sizes can result in reduced control. This incomplete control may reduce corn yield.
 Incomplete grass control due to herbicide stress: Grasses under stress from previous herbicide
applications may not be actively growing and susceptible to Accent Q.
 Ear malformation: Applications of Accent Q on corn that has 7 to 10 collars (V7 to V10) increases the
potential for ear malformation (pinching). This risk may be greatly reduced, but not eliminated, by
using drop nozzles properly adjusted so as to not apply Accent Q into the corn whorl.
APPLICATION RATE
Optimum control of the weeds listed can be achieved with 0.9 ounces (0.031 lb ai) of Accent Q. Weeds
that exceed the listed weed sizes by up to 50% may be partially controlled with rates between 0.9 and 1.8
ounces (0.031 and 0.061 lb ai) of Accent Q per acre.
Accent Q may be applied at 0.45 - 0.9 ounces (0.015 0.031 lb ai) for limited control of certain small
grass weeds. See the table for reduced rates under ADDITIONAL INSTRUCTIONS for details.
As weeds mature, their sensitivity to Accent Q decreases. As grassy weeds become mature (more than 3
tillers), they may not reach the size listed below, due to drought or other environmental factors. Treat
grassy weeds that are maturing rapidly before they reach the stages listed below.
When applied as directed, Accent Q will control the following weeds:

POPCORN, FIELD CORN GROWN FOR SEED AND SWEET CORN
Accent Q may be broadcast or applied with drop nozzles to popcorn or field corn grown for seed that is
less than 20" tall (free-standing) or that exhibits up to and including 5 leaf-collars (V5), whichever is most
restrictive. DO NOT apply to corn that is taller than 20" or that exhibits more than 5 leaf-collars (V5),
whichever is more restrictive.
Many seed companies have tested seed corn inbreds or yellow popcorn hybrids for sensitivity to Accent
Q and have reported excellent safety. DO NOT apply Accent Q to any white popcorn inbred, or white
popcorn hybrid unless specifically approved by the seed company. This includes “White Dynamite”
popcorn.
Accent Q may be applied to certain sweet corn hybrids grown for fresh markets or under contract for
processing. Applications of Accent Q may be applied broadcast or with drop nozzles (post-directed) on
sweet corn up to 12 inches tall or up to and including 5 leaf-collars (V5). For sweet corn 12 - 18 inches
tall, apply only with drop nozzles. DO NOT apply to sweet corn taller than 18 inches or those which
exhibit 6 or more leaf- collars (V6) and make only one application of Accent Q per year.
Sweet corn hybrid sensitivity to Accent Q is highly variable, and not all hybrids have been tested for crop
safety.
Not all seed corn inbreds, popcorn or sweet corn hybrids have been tested, nor does Corteva Agriscience
have access to all seed company data. Consequently, to the extent consistent with the law, Corteva
Agriscience is not responsible for any crop injury arising from the use of Accent Q on field corn grown for
seed, popcorn or sweet corn. When tank mixing, check the tank mix partner label for uses and
instructions for use.
SPRAY ADJUVANTS
Applications of Accent Q must include either a crop oil concentrate or a nonionic surfactant. In addition,
an ammonium nitrogen fertilizer must be used unless specifically prohibited by tank mix partner labeling.
Crop oil concentrate plus ammonium nitrogen fertilizer is the preferred adjuvant system for activity on
difficult to control species including woolly cupgrass, quackgrass, sandbur and wirestem muhly. Consult
local company fact sheets, technical bulletins, and service policies prior to using other adjuvant systems.
If another herbicide is tank mixed with
Accent Q, select adjuvants authorized for use with both products.
Products must contain only EPA-exempt ingredients (40 CFR 1001).
It is the pesticide users responsibility to ensure that all products are registered for the intended use. Read
and follow the applicable restrictions and limitations and directions for use on all product labels involved in
tank mixing. Users must follow the most restrictive directions for use and precautionary statements of
each product in the tank mixture.
When applied in tank mix combination with a glyphosate containing product that contains a built-in
adjuvant, including ABUNDIT
® Edge, ensure the total adjuvant load is equivalent to the directions on this
label.

COMPATIBILITY TESTING section below.
To the extent consistent with applicable law, weed control and crop response with tank mixtures not
specifically advised in this label are the responsibility of the user and manufacturer of the tank mix product. It is
the pesticide users responsibility to ensure that all products are registered for the intended use. Read and
follow the applicable restrictions and limitations and directions for use on all product labels involved in tank
mixing. Users must follow the most restrictive directions for use and precautionary statements of each product
in the tank mixture.
Tank Mixing Precaution
A corn plants predisposition to develop fused tissue emerging from the whorl (rattail) after the V11 stage may
increase when a product containing dicamba is applied to small corn under early stressful conditions. Be
aware of this when applying tank mixes with dicamba to small corn (V3 stage or smaller) under stressful
V93 / Accent® Q / Amendment / 11-04-2024 Page 22
conditions.
MIXING INSTRUCTIONS
Select a spray volume that will ensure thorough coverage and a uniform spray pattern. If tank mixing with other
herbicides, always consult the label of the tank mix partner(s) for minimum spray volume requirements and
apply the tank mixture using a water volume advised for all products.
1. Fill the tank 1/4 to 1/3 full of water.
2. While agitating, add the re quired amount of Accent Q.
3. Continue agitation until the Accent Q is fully dispersed, at least 5 minutes.
4. Once the Accent Q is fully dispersed, main tain agitation and continue filling tank with water.
Thoroughly mix Accent Q with water before adding any other material.
5. If tank mixing Accent Q with another herbicide, follow this mixing order: dry flowables and soluble
granules, followed by liquids, then oil dispersions (OD) or emulsifiable concentrates (EC). Maintain
continuous agitation.
6. As the tank is filling, add the required spray ad juvants (crop oil concentrate, nonionic surfactant, or
ammonium nitrogen fertilizer).
7. If the mixture is not continuously agitated, settli ng will occur. If settling occurs, thoroughly re-agitate
before using.
8. Apply Accent Q spray mixture within 24 hours of mixing to avoid product degradation.
9. If Accent Q and a tank mix partner are to be applied in multiple loads, pre-slurry the Accent Q in clean
water prior to adding to the tank. This will prevent the tank mix partner from interfering with the
dissolution of the Accent Q.
TANK MIX COMPATIBILITY TESTING
Perform a jar test prior to tank mixing to ensure compatibility of Accent Q and other pesticides. Use a clear
glass quart jar with lid and mix the tank mix ingredients in their relative proportions. Invert the jar containing the
mixture several times and observe the mixture for approximately 1/2 hour. If the mixture balls-up, forms flakes,
sludges, gels, oily films or layers, or other precipitates, it is not compatible and the tank mix combination may
not be used.
SEQUENTIAL ACCENT Q APPLICATIONS
Annual grasses may have more than one flush of emerging seedlings. Also, regrowth of treated annual
grasses may occur due to adverse environmental conditions following application. Perennial grasses may
regrow from underground stems or roots, depending upon environmental conditions. To control grasses under
these conditions, a sequential application of Accent Q may be necessary. The combined dosage of the
sequential applications cannot exceed 1.8 ounces (0.061 lb ai) per acre of Accent Q.
CULTIVATION
A timely cultivation may be necessary to control suppressed weeds, or weeds that emerge after an application
of Accent Q.
Optimum timing for cultivation is 714 days after Accent Q application or upon seeing the establishment of new
weeds.
CROP ROTATION
Rotational crops vary in their response to low concentrations of Accent Q remaining in the soil. Accent Q
dissipates rapidly in warm, acidic, microbiologically active soils.
The amount of Accent Q which may be present in the soil depends on application rate, soil pH and organic
matter content, elapsed time since application, crop production practices, and environmental factors.
V93 / Accent® Q / Amendment / 11-04-2024 Page 23
Injury to rotational crops may occur in high-pH, cold soils if dry weather prevails between application and
rotational crop planting. Consult your local Corteva Agriscience representative for additional guidelines.
Determine soil pH by laboratory analysis using the 1:1 soil:water suspension method on representative soil
samples taken at 04" depth. Soil pH varies within fields; therefore, base recropping on the highest soil pH
within each field. Consult local extension publications for advised soil sampling procedures.
Observe the following rotational intervals when using Accent Q at a maximum of 1.8 ounces (0.061 lb ai):

**Irrigated potatoes following irrigated corn treated in the States of Washington, Oregon, Idaho, or Utah can be planted 10 months after
using Accent Q on sprinkler irrigated corn with no soil pH restrictions, providing the maximum use rate on corn does not exceed 1.4 ounce
(0.048 lb ai) product per year. Corn treated with Accent Q must be grown to maturity and receive a minimum of 18 inches of irrigation
water before potatoes can be planted at this rotation interval. Injury to potatoes may occur if less than 18 inches of irrigation is used on the
previous corn crop. Accent Q may not be used in a tank mix or sequential application program with other ALS-inhibiting herbicides (Group
2 herbicides).

APPLICATION INFORMATION
Many crops are highly sensitive to Accent Q. All direct or indirect contact (including spray drift) with crops other
than field corn need to be avoided (see also SPRAY DRIFT MANAGEMENT).
GROUND APPLICATION
Broadcast Application
Use a minimum of 10 gallons water per acre. Under heavy weed pressure or dense crop foliage, increase
minimum spray volume to 15-25 gallons water per acre.
Ensure that equipment is set up to avoid applying an excessive rate directly over the rows and into the
corn plant whorl. This is most likely to occur when a nozzle is positioned directly above the row.
Overlaps or starting, stopping, slowing, and turning while spraying may result in crop injury.
Band Application
For band applications, use proportionately less spray mixture, and carefully calibrate the band applicator to not
exceed the labeled rate. Carefully follow the manufacturers instructions for nozzle type (flat fans), orientation,
distance of nozzles from the crop and weeds, spray volumes, calibration and spray pressure.
AERIAL APPLICATION
Aerial application is not permitted in New York and California.
Use nozzle types and arrangements that will provide optimum spray distribution and maximum coverage at a
minimum of 3 GPA.
SPRAYER PREPARATION/CLEANUP
It is important that spray equipment is clean and free of previous pesticide deposits before using Accent Q and
V93 / Accent® Q / Amendment / 11-04-2024 Page 25
then properly cleaned out following application. Clean all application equipment before applying Accent Q.
Follow the cleanup procedures specified on the label of the product previously sprayed. If no cleanup
procedure is provided, use the procedure that follows. Immediately following applications of Accent Q,
thoroughly clean all mixing and spray equipment to avoid subsequent crop injury.
When cleaning spray equipment before applying Accent Q, read and follow label directions for proper rinsate
disposal of the product previously sprayed.
Steam cleaning of aerial spray tanks will help to dislodge any visible pesticide deposits.
When spraying or mixing equipment will be used over an extended period to apply multiple loads of Accent Q,
partially fill the tank with fresh water at the end of each day of spraying, flush the boom and hoses, and allow to
sit overnight.
Cleanup Procedure
1. Drain the tank and thoroughly hose down the interior surfaces. Flush the tank, hoses, and boom with
clean water for a minimum of 5 min.
2. Partially fill the tank with clean water and add one gallon of household ammonia* (containing 3%
active) for every100 gallons of water. Finish filling the tank with water, then flush the cleaning solution
through the hoses, boom, and nozzles. Add more water to completely fill the tank and allow to
agitate/recirculate for at least 15 min. Again, flush the hoses, boom, and nozzles with the cleaning
solution, then drain the tank.
3. Repeat Step 2.
4. Remove the nozzles and screens and clean separate ly in a bucket containing the cleaning agent and
water.
5. Thoroughly rinse the tank with clean water for a minimum of 5 min, flushing the water through the
hoses and boom.
* Equivalent amounts of an alternate strength ammonia solution or a tank cleaner may be used.
