where/when conditions favor runoff.

Groundwater Advisory

Chlorimuron ethyl is known to leach through soil into groundwater under certain conditions as a result of label use.
Chlorimuron ethyl 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 rain water. 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 CLASSIC® if prevailing local conditions may be expected to result in off-site movement.

Non-target Organism Advisory

Chlorimuron ethyl 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 require ments specific to your State or Tribe, consult the agency
responsible for pesticide regulation.

this label or as otherwise permitted by FIFRA. Always read the entire label, including the Limitation of Warranty and Liability.

PRODUCT INFORMATION

CLASSIC® herbicide is a dispersible granule formulation to be mixed with water and sprayed for selective burndown, residual
and postemergence weed control of many broadleaf weeds and yellow nutsedge in soybeans, peanuts, and non -crop areas.
Residual applications of CLASSIC ® require rainfall or sprinkler irrigation to activate the herb icide. Degree of control and
duration of effect depend on: rate used, weed spectrum, growing conditions at and following time of treatment, soil pH,
texture, organic matter, moisture and precipitation.
Best residual control is obtained if CLASSIC ® is applied to moist soil and followed by rainfall or irrigation (~1”) before weeds
germinate. Several small rainfalls of less than 1/4” each are not as beneficial as one large rainfall of 1/2-1”. On dry soil, more
moisture is required for activation (1-2”) before weed emergence. If moisture is insufficient to activate the herbicide, a rotary
hoeing or shallow cultivation must be made after emergence of the crop while weeds are small enough to be controlled by
mechanical means. Deep cultivation reduces the effectiveness of CLASSIC ® and must be avoided.

BIOLOGICAL ACTIVITY

CLASSIC® rapidly inhibits the growth of susceptible weeds. Following application of preplant or preemergence treatment,
susceptible weeds may germinate and emerge, but growth then ceases and leaves become yellow and/or brown by 3-5 days
after emergence. Death of leaf tissue and growing point will follow in some species while others will remain green but stunted
and noncompetitive.

CLASSIC® will provide best results when applied to young, actively growing weeds. Leaves of susceptible plants yellow 3-5
days after application, followed, in controlled plants, by the death of the growing point. CLASSIC ® will provide complete
control of susceptible weeds in 7-21 days. Suppressed plants may remain green but will be stunted and noncompetitive.
Degree of control depends on: rate used; weed spectrum; weed size (if weeds are large, use higher rates and spray volume);
growing conditions at and following treatment; soil moisture; precipitation; and spray adjuvants.

Treating weeds under stress or large weeds may result in only partial control. Stress may be caused by:
x abnormal weather (hot or cold)
x mechanical injury from cultivation
x drought
x water-saturated soil
x disease
x insect injury
x prior herbicide injury
RESTRICTIONS
x Do not apply this product through any type of irrigation system.
x Do not apply CLASSIC® if rain is expected within 1 hour or weed control may decrease.
x Do not cultivate within 7 days of application.

681-20191204 Classic Herbicide (Master REDLINE) Page 5 of 27
x Do not apply CLASSIC® herbicide by air in the state of New York.
x Do not graze treated fields or harvest for hay within 14 days after application
x Do not contaminate any body of water.
x Do not mix/load, or use within 50 feet of all wells included abandoned wells, drainage wells, and sink holes.

Injury to or loss of desirable trees or vegetation may result from failure to observe the following:
x Do not apply CLASSIC® or drain or flush equipment on or near desira ble trees or other plants, on areas where their
roots may extend, or in locations where the chemical may be washed or moved into contact with their roots.
x Do not use on lawns, walks, driveways, or tennis courts.
x Prevent drift of spray to desirable plants.

PRECAUTIONS
x When triple-rinsing the pesticide container, be sure to add the rinsate to the spray mix.
x Failure to remove even small amounts of CLASSIC ® from application equipment may result in injury to subsequently
sprayed crops.
x Prevent spray drift to desirable plants.
x Stress affects some weeds, including pigweed, more than others. delay application until stress passes and weeds start
to grow again. Severe stress (drought, disease, insect damage, or nutrient deficiency including iron chlorosis) following
application may also result in crop injury and/or poor weed control.

WEED RESISTANCE MANAGEMENT
CLASSIC®, which contains the active ingredient chlorimuron ethyl, is a group 2 herbicide based on the mode of action
classification system of the Weed Science Society of America.

Proactively implementing diversified weed control strategies to minimize selection for weed populations resistant to one or
more herbicides is a best practice. A diversified weed management program may include the use of multiple herbicides with
different sites of action and overlapping weed spectrum with or without tillage operations and/or other cultural practices.
Research has demonstrated that using the labeled rate and directions for use is important to delay the selection for
resistance.

The continued effectiveness of this product depends on the successful implementation of a weed resistance management
program.

To aid in the prevention of developing weeds resistant to this product, users should:
x Scout fields before application to ensure herbicides and rates will be appropriate for the weed species and weed sizes
present.
x Start with a clean field, using either a burndown herbicide application or tillage.
x Control weeds early when they are relatively small (less than 4 inches).
x Apply full rates of CLASSIC® herbicide for the most difficult to control weed in the field at the specified time (correct
weed size) to minimize weed escapes.
x Scout fields after application to detect weed escapes or shifts in control of weed species.
x Control weed escapes before they reproduce by seed or proliferate vegetatively.
x Report any incidence of non-performance of this product against a particular weed to your DuPont AMVAC
representative, local retailer, or county extension agent.
x Contact your DuPont AMVAC representative, crop advisor, or extension agent to find out if suspected resistant weeds
to this MOA have been found in your region. If resistant biotypes of target weeds have been reported, use the
application rates of this product specif ied for your local conditions. Tank mix products so that there are multiple
effective sites of actions for each target weed.
x If resistance is suspected, treat weed escapes with an herbicide having a site of action other than group 2 and/or use
nonchemical methods to remove escapes, as practical, with the goal of preventing further seed production.

Suspected herbicide-resistant weeds may be identified by these indicators:
x Failure to control a weed species normally controlled by the herbicide at the dose applied, especially if control is
achieved on adjacent weeds;
x A spreading patch of non-controlled plants of a particular weed species; and
x Surviving plants mixed with controlled individuals of the same species.

Additionally, users should follow as many of the following herbicide resistance management practices as is practical:

681-20191204 Classic Herbicide (Master REDLINE) Page 6 of 27
x Use a broad spectrum soil-applied herbicide with other sites of action as a foundation in a weed control program.
x Utilize sequential applications of herbicides with alternative sites of action.
x Rotate the use of this product with non-group 2 herbicides.
x Avoid making more than two applications of CLASSIC ® herbicide and any other group 2 herbicides within a single
growing season unless mixed with an herbicide with a different site of action with an overlapping spectrum for the
difficult-to-control weeds.
x Incorporate non-chemical weed control practices, includin g mechanical cultivation, crop rotation, cover crops and
weed- free crop seeds, as part of an integrated weed control program.
x Use good agronomic principles that enhance crop development and crop competitiveness.
x Thoroughly clean plant residues from equipment before leaving fields suspected to contain resistant weeds.
x Manage weeds in and around fields, during and after harvest to reduce weed seed production.

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 consultants or
other qualified authorities to determine appropriate action treatment threshold levels for treating specific pest/crop systems
in your area.

SPRAY DRIFT MANAGEMENT ADVISORIES
THE APPLICATOR IS RESPONSIBLE FOR AVOIDING OFF-SITE SP RAY 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 redu ce spray drift, the potential for drift wi ll be greater if applications are made
improperly or under unfavorable environmental conditions.

Controlling Droplet Size – Ground Boom
x 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.
x Pressure - Use the lowest spray pressure recommended for the nozzle to produce the target spray volume and droplet
size.
x Spray Nozzle - Use a spray nozzle that is designed for the intended application. Consider using nozzles designed to
reduce drift.
Controlling Droplet Size – Aircraft
x 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 co mpatible 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 ft. above the crop canopyCANOPY, unless a greater application height is necessary for pilot safety.

Boom-less Ground Applications:
x Setting nozzles at the lowest effective height will help to reduce the potential for spray drift.

Handheld Technology Applications:
x Take precautions to minimize spray drift.

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 patterns 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 used, read and
carefully observe cautionary statements and all other information on the additive’s label. If using an additive that

681-20191204 Classic Herbicide (Master REDLINE) Page 8 of 27
increases viscosity, ensure that the nozzles and other application equipment will function properly with a viscous spray
solution. Preferred drift control additives have been cert ified by the Chemical Producer s and Distributors Association
(CPDA).

Rotational Crop Information

Even though CLASSIC ® may be applied in the fall, for the purposes of re-cropping, do not start counting months for re-
cropping until normal soybean planting time in the spring.

For rotational information following 1.0 oz . (0.25 oz. a.i.)/acre CLASSIC® in central region States, and up to 1.5 oz . (0.38
oz. a.i.)/acre applications in Southern Region States, use recrop Interval 2 or 3 in the ‘Rotational Crop Guidelines’ section
of this label.

For application of CLASSIC® greater than 1.0 oz. (0.25 oz. a.i.)/acre in the central region and greater than 1.5 oz. (0.38 oz.
a.i.)/acre in the Southern region, use recrop Interval 4 in the 'Rotational Crop Guid elines' section of this label. Sequential
applications of Synchrony® XP (AI: chlorimuron ethyl + thifensulfuron methyl; Reg. No. 352-648) or CLASSIC® following 1.0

7.0 also use recrop Interval 4.

Postemergence Application - Soybeans: All Regions
ANY SOYBEAN:
Timing to Crop Stage

CLASSIC® for in-season use on all soybean varieties, may be applied any time after the first trifolIate but no later than 60
days before soybean maturity.

681-20191204 Classic Herbicide (Master REDLINE) Page 11 of 27
Application Rate
CLASSIC® at 0.33 to 0.75 oz . (0.083 – 0.188 oz . a.i.)/acre may be applied postemergence to any soybean for broadleaf
weed control.

SOYBEAN VARIETIES DESIGNATED AS STS® OR SOYBEANS WITH BOLT® TECHNOLOGY:
x STS® soybeans or soybeans with Bolt ® technology are designed to be used at higher rates with CLASSIC ® due to a
higher resiliency to the active ingredient chlorimuron ethyl.
x Application of greater than 0.75 oz . (0.188 oz . a .i.)/acre CLASSIC ® to soybean varieties not designated as STS ® or
soybeans with Bolt® technology will result in severe crop injury and/or yield loss.
x DuPont AmvacAMVAC will not warrant the safety of this treatment to seed saved from previous year’s production
(bin run seed).
x These STS® soybeans or soybeans with Bolt® technology must be purchased from an authorized seed supplier.

Timing to Crop Stage
CLASSIC® for in-season use on STS® soybeans or soybeans with Bolt® technology can be applied any time after emergence
but no later than 60 days before soybean maturity.

Application Rate
CLASSIC® at 0.33 to 1.5 oz. (0.083 – 0.375 oz. a.i.)/acre may be applied postemergence on STS® soybeans or soybeans with
Bolt® technology. For rate limitations in certain geographies, see the "Rotational Crop Guidelines" section.

Timing to Weeds
x Apply CLASSIC® when weeds are young and actively growing (after the first true leaves have expanded, but before the
weeds exceed the size indicated below).
x Applications made to weeds larger than the sizes indi cated below, or to weeds under stress may result in
unsatisfactory control (see the “Biological Activity” section).

Cultivation

Do not cultivate within 7 days of application. cultivation may put weeds under stress by pruning roots, thus diminishing
control.

Cultivation approximately 14 days after application will help control suppressed weeds.

A second application of CLASSIC ® may be made 2–3 weeks after the initial a pplication to control weeds with multiple
germination flushes or suppressed weeds including burcucumber, Cocklebur, cowpea, giant ragweed, morningglory,
pigweed, sicklepod, and velvetleaf. Do not make more than 2 applications of CLASSIC® in a use year.

Spray Adjuvants
Applications of CLASSIC® must include a crop oil concentrate or nonionic surfactant except as specified in this labeling. An
ammonium nitrogen fertilizer may also be required. If another herbicide is tank mixed with CLASSIC ®, select adjuvants
authorized for use with both products. Adjuvants must contain only EPA-exempt ingredients.

Nonionic Surfactant
x Apply at 0.25% v/v (1 qt. per 100 gal. spray solution).
x Surfactant products must contain at least 60% nonionic surfactant with a hydrophilic/lipophilic balance (HLB) greater
than 12.

Crop Oil Concentrate
For improved weed control under hot, dry conditions, or for control of tough weeds like giant ragweed, a crop oil
concentrate may be used in place of a nonionic surfactant.
x Apply at 1% v/v (1 gal. per 100 gal spray solution).
x Oil adjuvants must contain at least 80% high quality, petroleum (mineral) or modified vegetable seed oil with at least
15% surfactant emulsifiers.
x Crop oil concentrate may increase the potential for crop injury in soybeans.

Ammonium Nitrogen Fertilizer

681-20191204 Classic Herbicide (Master REDLINE) Page 13 of 27
In addition to a nonionic surfactant or crop oil concentrate, an ammonium nitrogen fertilizer is required to control
velvetleaf.
x Use 2 qt./acre of a high-quality urea ammonium nitrate (UAN), including 28% N or 32% N, or 2 lb ./acre of a spray-
grade ammonium sulfate (AMS).
x Use 4 qt./acre UAN or 4 lb./acre AMS under arid conditions.
x Always use the lower rates of fertilizer with spray volumes of less than 15 gal/acre.

Special Adjuvant Types
x Combination adjuvant products may be used at doses that provide the required amount of NIS, COC, MSO and/or
ammonium nitrogen fertilizer. Consult product literature for use rates and restrictions.
x In addition to the adjuvants specified above, other adjuvant types may be used if they provide the same functionality
and have been evaluated and approved by DuPontAmvac AMVAC Product Management.

Tank Mixes
It is the pesticide user’s 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.

CLASSIC® may be applied in tank mixtures with organophosphate insecticides or at any time preceding or following an
application of an organophosphate insecticide on any STS ® soybean variety or soybeans with Bolt ® technology. Tank
mixtures of CLASSIC ® plus organophosphate insecticides applied to STS ® soybean varieties or soybeans with Bolt ®
technology may result in minor transient crop response (i.e. stunting and/or chlorosis). DO NOT apply CLASSIC® within 14
days before or after an application of an organophosphate insecticide on any soybean variety that is not STS® or soybeans
with Bolt® technology.

Other than the exceptions noted, and in addition to the tank mix partners and rates indicated in this label, CLASSIC ® may
be tank mixed or followed with sequential applications of other products registered for use in soybeans. CLASSIC® may be
applied in tank mix combinations with full or reduced rates of other products provided:
x The tank mix product is labeled for the same timing, meth od of application, adjuvants, and use restrictions as
CLASSIC®.
x The tank mix is not specifically prohibited on the label of the tank mix product.
x The tank mix combination is compatible as determined by a “jar test” described in the TANK MIX COMPATIBILITY

South Carolina, and Virginia.

CLASSIC® also suppresses bristly starbur in peanuts in the above mentioned states.

Timing to Crop Stage
CLASSIC® may be applied from 60 days after crop emergence to 45 days before harvest. Where peanut stands are erratic
or have been replanted, do not apply CLASSIC® until 60 days after the youngest peanuts have emerged.

Rate for Use on Peanuts

Make a single postemergence application of 0.5 oz. (0.125 oz. a.i.)/acre CLASSIC® for the control of actively growing Florida
beggarweed and the suppression of bristly starbur.

Timing to Weeds

681-20191204 Classic Herbicide (Master REDLINE) Page 18 of 27

Florida Beggarweed
x Apply before Florida beggarweed reaches 10" in height or begins to bloom.
x Florida beggarweed that regrows from mowing, cu ltivation or from a previous application of “Cadre®” DG herbicide
will only be suppressed.

Bristly Starbur
x Apply before bristly starbur reaches 10" in height.

Spray Adjuvants for Peanuts
x A nonionic surfactant must be included in the sp ray solution at the rate (concentration) of 2 pt . per 100 gal. of spray
solution so that a minimum of 0.125% v/v of actual nonionic surfactant is applied.
x Surfactant products must contain at least 60% nonionic surfactant with a hydrophilic/lipophilic balance (HLB) greater
than 12.
x Use only EPA approved surfactants authorized for use on food.
x Do not use a crop oil concentrate (either vegetable- or petroleum-based), as crop injury will result.
x For control of bristly starbur use 2 qt./acre of a high-quality urea ammonium nitrate (UAN), including 28%N or 32%N,
or 2 lbs./acre of a spray grade ammonium sulfate (AMS).

Fertilizer containing elemental sulfur must not be used.

Peanut Varieties

Varietal sensitivity to applications of CLASSIC® applications may vary. When using CLASSIC ® for the first time on a variety
other than those listed, treat only a portion of the field. If crop growth appears normal after 14 days, the balance of the
acreage may be treated.
x Southern runner has shown moderate resilience to CLASSIC®.
x DO NOT apply tank mixes of CLASSIC® + 2,4-DB to Southern runner.
x DO NOT apply to early bunch or Spanish-type varieties due to the risk of excessive crop injury.
Precautions:
Applications of CLASSIC® applied from 60 days after crop emergence to 45 days before peanut harvest on current runner-
type tomato spotted wilt virus resistant varieties may result in an increase in tomato spotted wilt virus symptoms which
may impact peanut yield.
CLASSIC® may cause a reduction in peanut vine length. Under normal growing conditions test data has shown no adverse
effects on yields.

The following conditions prior to or following CLASSIC® application can affect peanut yields:
x Environmental stress (drought)
x Damage from previous crop protection product application
x Damage from insects, nematodes, or disease
x Tank mixing CLASSIC® with elemental sulfur or products containing elemental sulfur.
x CLASSIC® applications other than those directed on this label

TANK MIX COMPATIBILITY TESTING

681-20191204 Classic Herbicide (Master REDLINE) Page 20 of 27
Perform a jar test prior to tank mixing to ensure compatibility of CLASSIC® and other pesticides. Use a clear glass quart jar
with lid and mix the tank mix ingredients in their relative proportions. invert Invert the jar containing the mixture several
times and observe the mixture for approximately 30 minutes. If the mixture balls-up, forms flakes, sludges, gels, oily film
or layers, or other precipitates, it is not compatible.

APPLICATION INFORMATION
Ground Application (Also refer to Spray Drift Management section)
Broadcast Application
x Postemergence, use a minimum of 10 gallons water per acre. under heavy weed pressure or dense crop foliage,
increase minimum spray volume to 15-25 gal/acre.
x Preemergence in soybeans, use a minimum of 10 gallons water per acre.
x For burndown applications of existing vegetation, use a minimum of 15 gallons water per acre. For large weeds and/or
heavy residue, increase gallonage to ensure coverage.
Band Application
x Because band applicators spray a narrower area than broadcas t applicators, use proportionately less spray solution
for band applications.
x Carefully calibrate the band applicator to not exceed the labeled rate.
x Flat fan nozzles are preferred.
Aerial Application (Also refer to Spray Drift Management section)
x Use nozzle types and arrangements that will provide op timum spray distribution and maximum coverage at 3–5
gal/acre.
x Use a minimum of 3 gallons water per acre. under heavy weed pressure or dense crop foliage, increase the minimum
spray volume to 5 gal/acre

MIXING INSTRUCTIONS
The following steps must be followed when preparing to spray CLASSIC®:

1. Fill the spray tank 1/4 to 1/3 full of water.
2. While agitating, add the required amount of CLASSIC®.
3. Continue adequate agitation.
4. CLASSIC® needs to be thoroughly mixed with water in the spray tank before adding any other material. As the tank is
filling, add (in order) :: other herbicide(s), the required spray adjuvant, and the nitrogen fertilizer where required.
Agitation is required for uniform mixing and application.
5. Apply CLASSIC® spray preparation within 24 hours of product mixing, or product degradation may occur.
6. If the mixture has settled, thoroughly re-agitate before using.

ROTATIONAL CROP GUIDELINES
Crop rotation intervals noted in the table below are based on crops grown under favorable growing conditions. Crops
grown under unfavorable environmental conditions, including drought, nutrient deficiency, high salts, disease and insect
pressure may demonstrate reduced resilience to crop protection chemicals. When deciding on a particular crop to replant
in your fields, carefully consider your particular soil and other field conditions.
x Important: Crops other than soybeans following a CLASSIC ® application can vary in their sensitivity to low
concentrations of CLASSIC® remaining in the soil. Rotational crop guidelines must be followed.
x When CLASSIC® is applied in sequence with Canopy® (AI: metribuzin + chlorimuron ethyl, Reg. 352-444), ENLITE® (AI:
thifensulfuron methyl + flumioxazin + chlorimuron ethyl, Reg. No. 352-757), Envive® (AI: chlorimuron methyl +

a.i.)/acre was applied during the use year (soil pH less than 7.0).

THE IMPORTANCE OF SOIL PH
Soil pH varies greatly. even within the same field pH variations as much as 2 pH units are common. composite
Composite soil samples taken across an entire field, in cluding those samples taken for soil fertility
specifications, may not detect areas of high pH. Subsampling is advised for areas likely to have pH values higher
than the field average. The following is a non-inclusiv e list of potential high pH areas where subsampling is
advised.
x Where different soil types are evident within a field, sample soil types separately.
x Where conditions vary within a field, sample areas separately, including:
o areas bordered by limestone gravel roads,

681-20191204 Classic Herbicide (Master REDLINE) Page 23 of 27
o river bottoms subject to flooding,
o low areas in hardpan soils where evaporative ponds may occur,
o eroded hillsides,
o along drain tile lines, and
o areas where drainage ditch spoil has been spread.

x Where lime has not been deeply incorporated, soil may exhibit significantly higher pH values in the upper 3 inches of
soil. Composite soil samples taken at a 6-8 inch depth may not reflect the elevated pH near the surface. In these cases
shallow sampling, the upper 3 inches, is advised.

Determine soil pH by laboratory analysis using a 1:1 soil:water suspension.

SPRAYER PREPARATION AND CLEANUP

It is important that spray equipment is clean and free of previous pesticide deposits before using CLASSIC ® and then
properly cleaned out following application. Clean all application equipment before applying CLASSIC®. Follow the cleanup
procedures specified on the label of the product previous ly sprayed. If no cleanup procedure is provided, use the
procedure that follows. Immediately following applications of CLASSIC®, thoroughly clean all mixing and spray equipment
to avoid subsequent crop injury.

Note:
x When cleaning spray equipment before applying CLASSIC®, read and follow label directions for proper rinsate disposal
of the product previously sprayed.
x Steam cleaning of aerial spray tanks will help to dislodge any visible pesticide deposits.
x When spraying or mixing equipment will be used over an extended period to apply multiple loads of CLASSIC ®,
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 every
100 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, screens and end caps of sprayer booms and clean separately 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 specified in the bulletin “Sulfonylurea
Herbicides, A Guide to Equipment Cleanout,” may be used.
