Engineering Controls:
When handlers use enclosed cabs in a manner that meets the requirements listed in the Worker Protection Standard (WPS) for
agricultural pesticides [40 CFR 170.240 (d) (4, 5)], the handler PPE requirements may be reduced or modified as specified in the
WPS.
USER SAFETY RECOMMENDATIONS
Users should wash hands before eating, drinking, chewing gum, using tobacco or using the toilet. Users should remove
clothing/PPE immediately if pesticide gets inside. Then wash thoroughly and put on clean clothing. Users should 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.
ENVIRONMENTAL HAZARDS
Simazine can travel (seep or leach) through soil and can contam inate ground water which may be used as drinking water.
Simazine has been found in ground water. Users are advised not to apply simazine to sand and loamy soils where the water
table (ground water) is close to the surface and where the soils are very permeable, i.e., well-drained. Your local agricultural
agencies can provide further information on the type of soil in your area and the location of ground water.
This product is toxic to aquatic invertebrates. Do not apply directly to water, or to areas where surface water is present or to
intertidal areas below the mean high water mark. Runoff and drift from treated areas may be hazardous to aquatic organisms
in neighboring areas. Do not contaminate water when disposing of equipment wash water.
Product must not be mixed or loaded within 50 feet of intermittent streams or rivers, natural or impounded lakes and
reservoirs. Product must not be applied within 66 feet of the points where field surface water runoff enters perennial or
intermittent streams and rivers or within 200 ft. of natural or impounded lakes and reservoirs. If this product is applied to
highly erodible land, the 66 foot buffer or setback from runoff points must be planted to crop or seeded with grass or other
suitable crop.
Product must not be mixed/loaded, or used within 50 feet of all wells, including abandoned wells, drainage wells, and sink
holes. Operations that involve mixing, loading, rinsing or washing of this product into or from pesticide handling or
application equipment or containers within 50 feet of any well are prohibited unless conducted on an impervious pad
constructed to withstand the weight of the heaviest load that may be positioned on or moved across the pad. Such a pad
shall be designed and maintained to contain any product spill or equipment leaks, container or equipment rinse or
washwater and rain water that may fall on the pad. Surface water shall not be allowed to either flow over or from the pad,
which means that the pad must be self-contained. The pad shall be sloped to facilitate material removal. An unroofed pad
shall be of sufficient capacity to contain a minimum of 110% of the capacity of the largest pesticide container or application
equipment on the pad. A pad that is covered by a roof of sufficient size to completely exclude precipitation from contact
with the pad, shall have a minimum containment capacity of 100% of the largest pesticide container or application
equipment on the pad. Containment capacities as described above shall be maintained at all times. The above specified
minimum containment capacities do not apply to vehicles when delivering pesticide shipments to the mixing or loading
sites.
Additional state-imposed requirements regarding well-head setbacks and operational area containment must be observed.
One of the following restrictions must be used in applying simazine to tile-outletted terraced fields containing standpipes:
x Do not apply within 66 feet of standpipes in tile-outletted terraced fields.
x Apply this product to the entire tile-outletted terraced field and immediately incorporate it to a depth of 2-3 inches in
the entire field.
x Apply this product to the entire tile-outletted terraced field under a no-till practice only when a high crop residue
management practice is practiced. High crop residue management is described as a crop management practice where
little or no crop residue is removed from the field during and after crop harvest.
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 site. Protect the forage and habitat of non-
target organisms by following label directions intended to minimize spray drift.

AGRICULTURAL USE REQUIREMENTS
Use this product only in accordance with its labeling and with the Worker Protection Standard, 40 CFR part 170. This Standard
contains requirements for the protection of agricultural workers on farms, forests, nurseries, and greenhouses, and handlers
of agricultural pesticides. It contains requirements for training, decontamination, notification, and emergency assistance. It
also contains specific instructions and exceptions pertaining to the statements on this label about personal protective
equipment (PPE), and restricted-entry interval. The requirements in this box only apply to uses of this product that are covered
by the Worker Protection Standard.
For Christmas trees, do not enter or allow worker entry into treated areas during the restricted-entry interval (REI) of 48 hours.
For all other crops and use patterns, do not enter or allow worker entry into treated areas during the REI of 12 hours.
Exception: If the product is soil-injected or soil-incorporated, the Worker Protection Standard, under certain circumstances,
allows workers to enter the treated area if there will be no contact with anything that has been treated.
PPE required for early entry to treated areas that is permitted under the Worker Protection Standard and that involves contact
with anything that has been treated, such as plants, soil, or water, is: coveralls, waterproof gloves and shoes plus socks.
NON-AGRICULTURAL USE REQUIREMENTS
The requirements in this box apply to uses of this product that are NOT within the scope of the Worker Protection Standard
for agricultural pesticides (40 CFR Part 170). The WPS applies when this product is used to produce agricultural plants on
farms, forests, nurseries, or greenhouses.
Do not enter or allow others (including children or pets) to enter until sprays have dried.
PRODUCT INFORMATION
Apply this herbicide before weeds emerge or after removal of weed growth. SIMAZINE 90DF controls a wide variety of annual
broadleaf and grass weeds when used at selective rates in agricultural crops and ornamental plantings. When used at higher
nonselective rates in noncrop areas, it also controls many perennial broadleaf and grass weeds.
Where a range of application rates is given, use the low rate on coarser textured soil and soil low in organic matter; use the
high rate on fine textured soil and soil high in organic matter.
Since this product enters weeds mainly through their roots, moisture is needed to move it into the root zone. Very dry soil
conditions and lack of rainfall following application may necessitate shallow cultivation.
This product is noncorrosive to equipment, nonflammable, and has low electrical conductivity.
Failure to follow the directions for use and precautions on this label may result in crop injury, poor weed control, and/or illegal
residues.

WEED RESISTANCE MANAGEMENT
FOLLOWING MANY YEARS OF CONTINUOUS USE OF SIMAZINE AND CHEMICALLY RELATED PRODUCTS, BIOTYPES OF
SOME OF THE WEEDS LISTED ON THIS LABEL HAVE BEEN REPORTED WHICH CANNOT BE EFFECTIVELY CONTROLLED BY
THIS AND RELATED HERBICIDES. WHERE THIS IS KNOWN OR SUSPECTED AND WEEDS CONTROLLED BY THIS PRODUCT
ARE EXPECTED TO BE PRESENT ALONG WITH RESISTANT BIOTYPES, WE RECOMMEND THE USE OF THIS PRODUCT IN
REGISTERED COMBINATIONS OR IN SEQUENCE WITH OTHER REGISTERED HERBICIDES WHICH ARE NOT TRIAZINES. IF
ONLY RESISTANT BIOTYPES ARE EXPECTED TO BE PRESENT, USE A REGISTERED NON-TRIAZINE HERBICIDE. CONSULT
YOUR STATE AGRICULTURAL EXTENSION SERVICE FOR SPECIFIC RECOMMENDATIONS.
For resistance management, SIMAZINE 90DF contains a Group 5 herbicide simazine. Any weed population may contain or
develop plants naturally resistant to SIMAZINE 90DF and other Group 5 herbicides. The resistant biotypes may dominate
the weed population if these herbicides are used repeatedly in the same field. Appropriate resistance management
strategies should be followed.
To delay herbicide resistance, take one or more of the following steps:
x Rotate the use of SIMAZINE 90DF or other Group 5 herbicides within a growing season sequence or among
growing seasons with different herbicide groups that control the same weeds in a field.
x 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.
x 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.
x Fields should be scouted prior to application to identify the weed species present and their growth stage to
determine if the intended application will be effective.
x Scout after herbicide application to monitor weed populations for early signs of resistance development.
Indicators of possible herbicide resistance include:
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 plants 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 such as 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.
x If a weed pest population continues to progress 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.
x Contact your local extension specialist, certified crop advisors, and/or Winfield Solutions, LLC representative for
pesticide resistance management and/or integrated weed management recommendations for specific crops and
resistant weed biotypes.
x For further information or to report suspected resistance, contact your Winfield Solutions, LLC representative.

APPLICATION PROCEDURES
Ground application: Use conventional ground sprayers equipped with nozzles that provide accurate and uniform application.
Be certain that nozzles are uniformly spaced and the same size. Calibrate sprayer before use and recalibrate at the start of each
season and when changing carriers. Unless otherwise specified, use a minimum of 20 gallons of spray mixture per acre.
Use a pump with capacity to (1) provide sufficient agitation in tank to keep mixture in suspension, and (2) to provide a
minimum of 20% bypass at all times. Use centrifugal pumps which provide propeller shear action for dispersing and mixing
this product. The pump should provide a minimum of 10 gals./ minute/100 gals. tank size circulated through a correctly
positioned sparger tube or jets.
Use screens to protect the pump and to prevent nozzles from clogging. Screens placed on suction side of pump should be 16-
mesh or coarser. Do not place a screen in the recirculation line. Use 50-mesh or coarser screens between the pump and boom,
and where required, at the nozzles. Check nozzle manufacturer's recommendations.
For band applications, calculate amount to be applied per acre as follows:
band width X broadcast rate per acre = amount needed per
row width in inches acre of field
Mixing procedures--all uses: (1) Be sure sprayer is clean and not contaminated with any other materials, or crop injury or
sprayer clogging may result. (2) Fill tank ¼ full with clean water, nitrogen solution or complete, fluid fert ilizer. (3) Start
agitation. (4) Be certain that the agitation system is working properly and creates a rippling or rolling action on the liquid
surface. (5) Pour product directly from bag into tank. (6) Continue filling tank until 90% full. Increase agitation if necessary to
maintain surface action. (7) Add tank mix herbicide(s) after th is product is thoroughly suspended. (8) Finish filling tank.
Maintain agitation to avoid separation of materials. (9) Empty tank as completely as possible before refilling to prevent buildup
of emulsifiable concentrate residue from possible tank mix herbicides. (10) lf an emulsifiable concentrate film starts to build up
in tank, drain it and clean with strong detergent solution or solvent. (11) Clean sprayer thoroughly immediately after use by
flushing system with water containing a detergent.
Compatibility test: To determine the tank mix compatibility of SI MAZINE 90DF with liquid fertilizer, crop oil, spreaders, or
recommended pesticides, use this test method. Nitrogen solutions or complete fluid fertilizers may replace all or part of the
water in the spray in corn. Since Iiquid fertilizers can vary, even within the same analysis, check compatibility each time before
use. Be especially careful when using complete suspension or fluid fertilizers as serious compatibility problems are more apt
to occur. Commercial application equipment may improve compat ibility in some instances. Check compatibility using this
procedure:
1. Add 1 pint of fertilizer to each of 2 one-quart glass jars with tight lids.
2. To one of the jars add ¼ teaspoon of a compatibility agent approved for this use (¼ teaspoon is equivalent to 2
pints per 100 gallons spray). Cap and shake until mixed. Examples of compatibility agents include Complex ®,
Combine or Unite®.
(NOTE: Complex, Combine and Unite are not registered for use in California.)
3. To both jars add the appropriate amount of herbicide(s). If more than one herbicide is used, add them separately
with dry herbicides first, flowables next, and emulsifiable concentrates last. After each addition, cap and shake until
thoroughly mixed. The appropriate amount of herbicides for this test follows (assuming a spray volume of 25 gallons
per acre):
Dry herbicides: For each pound per acre add 1.5 teaspoons to each jar. Fluff up wettable powder products before
measuring.
Liquid herbicides: For each pint per acre add 0.5 teaspoons to each jar.
For a spray volume other than 25 gallons per acre, change the teaspoons added to each jar as follows:
25 gallons x no. teaspoons given above = teaspoons to add
desired gallons spray volume per acre to each jar
4. After adding all ingredients, put lids on and tighten. Sh ake jars vigorously one minute. Let the mixtures stand 15
minutes and then look for separation, large flakes, precipitates, grease, gels, medium to heavy oily film on the jar, or
other signs of incompatibility. Determine if the compatibility agent is needed in the spray mixture by comparing the
two jars. If either mixture separates, but can be remixed readily, the mixture probably can be sprayed as long as
good agitation is used. If the mixtures are incompatible, test the following methods of improving compatibility: (A)
slurry the dry herbicide(s) in water before addition, or (B) add ½ of the compatibility agent to the fertilizer and the
other ½ to the emulsifiable concentrate or flowable herbicide before addition to the mixture. If still incompatible, do
not use the materials mixed in the same spray tank.
Rotational Crops and Perennial Crop Replanting
To avoid crop injury, observe the following precautions: (1) If rotating treated land the year following application, plant only
corn, unless otherwise stated in this label. (2) If replanting perennial crops or if rotating land to crops other than corn, do not
apply this product in the year preceding planting these crops.

SPRAY DRIFT MANAGEMENT
MANDATORY SPRAY DRIFT MANAGEMENT
Ground Boom Applications:
x User must only apply with the release height recommended by the manufacturer, but no more than 4 feet
above the ground or crop canopy.
x Applicators are required to use a coarse or coarser droplet size (ASABE S572).
x Do not apply when wind speeds exceed 10 miles per hour at the application site.
x Do not apply during temperature inversions.
x User must maintain a 15 foot (4.6 meter) in-field downwind buffer (in the direction in which the wind is
blowing) from the edge of streams and rivers, as well as high-tide line for all estuarine/marine environments.
SPRAY DRIFT ADVISORIES
THE APPLICATOR IS RESPONSIBLE FOR AVOIDING OFF-SITE SPRAY DRIFT. BE AWARE OF NEARBY NON-TARGET SITES
AND ENVIRONMENTAL CONDITIONS.
Avoid spray overlap as crop injury may result.
Importance of Droplet Size:
An effective way to reduce spry 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 o r
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.
Boom Height - Ground Boom
For ground equipment, the boom should remain level with the crop and have minimal bounce.
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. Temperat ure 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.
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.
Handheld Technology Application
Take precautions to minimize drift.
FRUIT AND NUT CROPS
Apply the spray to the orchard or vineyard floor avoiding contact with fruit, foliage, or stems. Recommended rates are based
on broadcast treatment. For band application, or spot applications around fruit or nut trees, reduce the broadcast rate of this
product and water per acre in proportion to the area actually sprayed.
Use Precautions and Restrictions (All fruit and nut crops): 1) Applications made by mechanically pressurized handguns are
restricted to spot treatment only for the following uses: Citrus (Grapefruit, Orange, Lemons); Pome Fruit (Apples, Pears);
Stone Fruits (Cherries [sweet, tart], Peaches, Plums); Tree Nuts (Pecans, Walnuts, Filberts, Almonds, Macadamia Nuts);
Berry and Small Fruit (Blueberries, Blackberries, Loganberries, Raspberries, Grapes, Lowbush blueberries); and Tropical
and Sub-tropical Fruits (Avocado, Olive). 2)To avoid crop injury: a) Apply only to orchards or groves where trees have been
established 12 months or more unless specified differently. b) Make only one application per year, except as noted otherwise.
c) Do not use on gravelly, sand, or loamy sand soil. d) Immediately following application, limit overhead sprinkler irrigation to
½ inch.
7
Almonds and Peaches (CA only)
Apply 1.1-2.2 pounds per treated acre in a 2-4 foot band on each side of the tree row. Apply before weeds emerge in late fall or
early winter. Weeds controlled by 1.1 pounds include burclove r, common chickweed, wild mustard, and shepherdspurse.
Apply only once per calendar year. Do not apply more than 2.2 lbs per calendar year.
Use Precautions and Restrictions: To avoid crop injury: 1) Do not treat trees established in the grove less than 3 years. 2) Do
not treat the Mission (Texas) variety of almonds. 3) Do not apply to almond trees propagated on plum rootstocks. 4) Do not
replant almonds or peaches in treated soil for 12 months after treatment. 5) Do not apply on soil with less than 1% organic

FIELD CROPS
Corn
Nitrogen solutions or complete fluid fertilizers may replace all or part of the water as a carrier in the spray. Determine the
physical compatibility of this product with fertilizer before use. Refer to the GENERAL INFORMATION section of this label for a
compatibility test. Do not apply after corn has emerged as there is a danger of liquid fertilizers causing crop injury.
Preemergence: Apply before weeds and corn emerge. Apply a maximum of 2.2 pounds per acre as a single preemergence
application on soils that are not highly erodible or on highly erodible soils, as defined by the Natural Resources
Conservation Service, if at least 30% of the soil is covered with plant residues. If a second treatment is required following
an earlier herbicide application, the total SIMAZINE 90DF applied may not exceed 2.7 pounds per acre per calendar year.
Apply a maximum of 1.7 pounds per acre as a single preemergence application on highly erodible soils if <30% of the soil
is covered with plant residues.
Preplant: Apply in the spring after plowing at the appropriate rate in the table below. Apply before, during, or after final
seedbed preparation. If soil is tilled or worked after application, avoid deep incorporation. Best results will be obtained when
this product is applied within 2 weeks of planting. Under dry weather conditions, preplant applications may give better weed
control. If weeds develop, particularly under relatively dry conditions, a shallow cultivation will generally result in better weed
control.

Use Precautions and Restrictions: On newly sprigged turfgrass, hybrid bermudagrass, nondormant bermudagrass, or
nondormant zoysia grass, temporary slowing of growth and yellowing may occur following application. To avoid turf
injury, (1) Use only on turfgrass reasonably free of infestations of insects, nematodes, and diseases. (2) Do not use north of
NC (except may be used in the Virginia Coastal Plains) or west of Highway 281 in Texas and Oklahoma. (3) Do not use on
muck or alkaline soils. (4) Do not apply over the rooting area of trees or ornamentals not listed on this label. (5) Do not
seed or overseed with desirable turfgrass within 4 months before or 6 months after treatment. (6) Do not apply this
product on newly seeded grasses until they have overwintered and have a well-developed rhizome system. (7) Do not
exceed 2.2 lbs. product/A within 12 months of seeding grasses.
Do not graze or feed turf clippings to animals.
TURFGRASS FOR FAIRWAYS, LAWNS, AND SIMILAR AREAS
For use on warm season turf grass only (Bermudagrass, Centipedegrass, St. Augustinegrass, and Zoysia Grass).
Apply SIMAZINE 90DF after September 1 (after October 1 for annual bluegrass) before emergence of winter annual weeds.
SIMAZINE 90DF will control annual bluegrass, burclover, lawn burweed, common and mouseear chickweed, corn
speedwell, henbit, hop clover, spurweed, and parsley-piert. SIMAZINE 90DF will also control these weeds soon after
emergence. For control of summer annual weeds listed in the General Information section of this label, apply SIMAZINE
90DF in late winter before the weeds emerge. Apply in a minimum of 15 gallons of water per acre.
Turfgrass for Fairways: Where annual bluegrass is the major weed, use 1.1 lbs. of SIMAZINE 90DF per acre (0.4 oz. per 1000
sq. ft.). Use 1.1-2.2 lbs. per acre (0.4-0.8 oz. per 1,000 sq. ft.) for control of other weeds. However, do not exceed 1.1 lbs. per
acre per treatment on newly sprigged turfgrass or on hybrid bermudagrass such as Tiflawn, Tifway, and Ormond. Irrigate
with ½ inch of water if rainfall does not occur within 10 days after preemergence treatment. For control of summer annuals
which emerged after the initial application, apply an additional 1.1 lbs./A at least 30 days after the initial application, but not
after June 1. However, do not make more than two applications per year.

Turfgrass for Lawns & Similar Areas: Where annual bluegrass is the major weed, use 1.1 lbs. of SIMAZINE 90DF (0.99 lb. ai)
per acre (0.4 oz. per 1000 sq. ft.). Use 1.1 - 1.75 lbs. of SIMAZINE 90DF (0.99 - 1.57 lbs. ai) per acre (0.4 - 0.64 oz. per 1, 000
sq. ft.) for control of other weeds. However, do not exceed 1.1 lbs. of SIMAZINE 90DF (0.99 lb. ai) per acre per treatment on
newly sprigged turfgrass or on hybrid bermudagrass such as Tiflawn, Tifway, and Ormond. For control of summer annuals
which emerged after the initial application, apply an additional 1.1 lbs. of SIMAZINE 90DF (0.99 lb. ai) per acre at least 30
days after the initial application, but not after June 1. However, do not make more than two applications per year.
Important: The treated area must be irrigated with 0.5 inches of water immediately after treatment. If no irrigation is
planned the maximum amount of SIMAZINE 90DF that may be applied per treatment is 0.7 lb. (0.63 lb. ai) per acre (0.26 oz.
per 1000 sq. ft).
Use Precautions and Restrictions: On newly sprigged turfgrass, hybrid bermudagrass, nondormant bermudagrass, or
nondormant zoysia grass, temporary slowing of growth and yellowing may occur following applications. To avoid turf
injury: (1) Use only on turfgrass reasonably free of infestations of insects, nematodes, and diseases. (2) Do not use on golf
greens. (3) Do not use north of NC (except may be used in the Virginia Coastal Plains) or west of Highway 281 in Texas and
Oklahoma. (4) Do not use on muck or alkaline soils. (5) Do not apply over the rooting area of trees or ornamentals not
listed on this label. (6) Do not seed or overseed with desirable turfgrass within 4 months before or 6 months after
treatment. (7) Do not apply this product on newly seeded grasses until they have overwintered and have a well-developed
rhizome system. (8) Do not exceed 2.2 lbs. per acre within 12 months of seeding grasses.
Note: Do not graze or feed turf clippings to animals or illegal residues may result.
Tank Mixture with Glyphosate (4 lb. ai/gal.)
This tank mixture will provide control of emerged annual weed s and residual control of weeds listed on this label. The
combination also will partially control emerged perennial weeds listed on this label. Add to the spray tank the appropriate rate
of SIMAZINE 90DF noted above when used alone. Then add 1-5 qts. of a 4 lb. ai/gal. glyphosate depending on weeds present
and their growth stage. Also add an agriculturally approved nonionic surfactant at the rate recommended by the specific
glyphosate label used. Apply the mixture in 10-40 gals. of water per acre as a postemergence spray at the appropriate weed
growth stage given on the glyphosate label. Provide constant agitation during mixing and application to keep the mixture in
suspension. Refer to the Application Procedures section of this label for further directions. Refer to the labels of both
herbicides for specific noncrop sites, rates, weeds controlled, and further directions, precautions and limitations.
Tank Mixture with Oust®
Use this tank mixture to control the weeds listed below with either preemergence, early postemergence, or postemergence
applications. Use the higher rates within the ranges given under conditions of heavy weed growth, on soil with over 2½%
organic matter, on areas with heavy decaying plant residues, or on high moisture areas such as along road edges or railroad
shoulders. To improve wetting and/or contact activity on emerged weeds, add a nonionic surfactant at 1 qt. per 100 gals. of
spray. Do not apply by aircraft. Provide constant agitation during mixing and application to keep the mixture in suspension.
Refer to the labels of both herbicides for specific noncrop sites and further directions, precautions, and limitations.
Preemergence to Early Postemergence: To control the weeds listed below, use the appropriate rate given elsewhere on this
label for SIMAZINE 90DF applied alone to the crop being treated plus 3-5 oz. of Oust in a minimum of 25 gals. of water per
acre.
