PPE requirements may be reduced or modified as specified in the WPS.
USER SAFETY RECOMMENDATIONS
Users should: 1) Wash hands before eating, drinking, chewing gum, using tobacco or using the toilet. 
2) Remove clothing/PPE immediately if pesticide gets inside. Then wash thoroughly and put on clean 
clothing. 3) 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 enter 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 sand soils where the water table (ground water) is close to the surface and where these 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 pesticide is toxic to aquatic invertebrates. Do not apply directly to water, 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 washwater.
Product must not be mixed or loaded within 50 feet of intermittent streams and rivers, natural or impounded 
lakes and reservoirs. Product must not be applied within 66 feet of points where field surface water runoff 
enters perennial or intermittent streams and rivers or within 200 feet of natural or impounded lakes and 
reservoirs. If this product is applied to highly erodible land, the 66-foot buffer or setback from runoff entry 
points must be planted to crop, or seeded with grass or other suitable crop.
Product must not be mixed or 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 spills 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 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 at 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

Page 3 of 25 
 
precipitation from contact with the pad shall have a minimum containment of 100% of the capacity 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 to the mixing/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:
• Do not apply within 66 feet of standpipes in tile-outletted terraced fields.
• Apply this product to the entire tile-outletted terraced field and immediately incorporate it to a depth of 2 
to 3 inches in the entire field.
• 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.

USE INFORMATION
IMPORTANT: Read the entire “DIRECTIONS FOR USE” and the “WARRANTY—CONDITIONS OF SALE”
before using this product.
This product is a herbicide that should be applied before weeds emerge or following removal of weed 
growth. It controls a wide variety of annual Broadleaf and Grass weeds when used at selective rates in 
agricultural and ornamental crops. Where a range of application rates is given, use the lower rate on 
Coarser textured soil and soil lower in organic matter; use the higher rate on Finer textured soil and soil 
higher in organic matter.
To avoid spray drift, do not apply under windy conditions. Avoid spray overlap as crop injury may result.
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 or rotary 
hoeing. This product is non-corrosive to equipment and nonflammable.
USE SITE RESTRICTION
Not for use in the States of Alaska, Hawaii or in the U.S. territories (American Samoa, Guam, North 
Mariana Islands, Puerto Rico and the U.S Virgin Islands).
WEED RESISTANCE MANAGEMENT
For resistance management, this product is a Group 5 mode of action herbicide. Any weed population may 
contain or develop plants naturally resistant to this product and other Group 5 mode of action 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 this product 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 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 
SIMAZINE GROUP 5 HERBICIDE

Page 5 of 25 
 
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 or certified crop advisors for additional pesticide resistance-
management and/or integrated weed-management recommendations for specific crops and weed 
biotypes. 
x For further information or to report suspected resistance, contact Drexel Chemical Company 
representatives at (901) 774-4370.
CHEMIGATION
Apply SIMAZINE 4F only through sprinkler, including center pivot, lateral move, end tow, side [wheel] roll, 
traveler, big gun, solid set, hand move or microsprinkler irrigation systems. Do not apply this product through 
any other type of irrigation system. Crop injury, lack of effectiveness or illegal pesticide residues in the crop 
can result from non-uniform distribution of treated water.
If you have questions about calibration, you should contact your State Extension Service Specialists, 
equipment manufacturers or other experts.
Do not connect an irrigation system (including greenhouse systems) used for pesticide application to a 
public water system unless the pest icide label-prescribed safety device s for public water systems are in
place.
A person knowledgeable of the chemigation system and responsible for its operation, or under the 
supervision of the responsible person, shall shut the system down and make necessary adjustments should
the need arise.
Public water system means a system for the provision to the public of piped water for human consumption 
if such system has at least 15 service connections or regularly serves an average of at least 25 individuals
daily at least 60 days out of the year.
Chemigation systems connected to public water systems must contain a functional, reduced-pressure zone 
backflow preventer (RPZ) or the functional equivalent in the water supply line upstream from the point of 
pesticide introduction. As an option to the RPZ, the water from the public water system should be 
discharged into a reservoir tank prior to pesticide introduction. There shall be a complete physical break 
(air gap) between the outlet end of the fill pipe and the top or overflow rim of the reservoir tank of at least 
twice the inside diameter of the fill pipe.
The pesticide injection pipeline must contain a functional, automatic, quick-closing check valve to prevent 
the flow of fluid back toward the injection pump.
The pesticide injection pipeline must contain a functional, normallyclosed, solenoid-operated valve located 
on the intake side of the injection pump and connected to the system interlock to prevent fluid from being 
withdrawn from the supply tank when the irrigation system is either automatically or manually shut down.
The system must contain functional interlocking controls to automatically shut off the pesticide injection 
pump when the water pump motor stops, or in cases where there is no water pump, when the water 
pressure decreases to the point where pesticide distribution is adversely affected.

Page 6 of 25 
 
Systems must use a metering pump, such as a positive displacement injection pump (e.g., diaphragm 
pump) effectively designed and constructed of materials that are compatible with pesticides and capable of 
being fitted with a system interlock.
Do not apply when wind speed favors drift beyond the area intended for treatment.
Information regarding agitation, time of pesticide application during water application and mixing 
instructions is included in Sprinkler Chemigation statements.
The system must contain a functional check valve, vacuum relief valve and low pressure drain appropriately 
located on the irrigation pipeline to prevent water source contamination from backflow. The pesticide 
injection pipeline must contain a functional, automatic, quick-closing check valve to prevent the flow of fluid 
back toward the injection pump.
The pesticide injection pipeline must also contain a functional, normally closed, solenoid-operated valve 
located on the intake side of the injection pump and connected to the system interlock to prevent fluid from 
being withdrawn from the supply tank when the irrigation system is either automatically or manually shut 
down.
The system must contain functional interlocking controls to automatically shut off the pesticide injection 
pump when the water pump motor stops.
The irrigation line or water pump must include a functional pressure switch which will stop the water pump 
motor when the water pressure decreases to the point where pesticide distribution is adversely affected. 
Systems must use a metering pump, such as a positive displacement injection pump (e.g., diaphragm 
pump) effectively designed and constructed of materials that are compatible with pesticides and capable of 
being fitted with a system interlock.
PRE-EMERGENCE OR POST-EMERGENCE: Apply this product alone or in tank mixtures with other 
herbicides on this label which are registered for center pivot application with irrigation water. Apply either 
after planting, before crop and weeds emerge, or after crop emergence, but before lay-by (20 to 30 inches) 
and before weeds exceed 12 inches in height. Apply at rates specified on this label. Prepare mixture with 
minimum of 1 part water to 1 part product. Injecting a larger volume of a more dilute slurry per hour will 
assure more accurate calibration of metering equipment. Maintain sufficient agitation to keep herbicide in 
suspension. Meter slurry into irrigation water during entire period. Apply in 0.5 to 1 inch of water. Use the 
lower water volume on Coarser textured soils, the higher volume on Finer textured soils. More than 1 inch 
of water may reduce weed control by moving herbicide below the effective zone in the soil. Inject dilute 
slurry into system through positive displacement pump.
USE PRECAUTIONS:
x Apply only through irrigation systems containing anti-siphon and check valves to prevent contamination 
of well during shutdown and overflow of solution.
x Inject ahead of any right angle turn in the main line to ensure adequate mixing.
x Chemical injection pumps and water pumps must have interlocking controls to ensure simultaneous 
shutoff.
x Application when drift may occur from windy conditions, when system joints and connections are leaking 
or when nozzles are not providing uniform distribution may cause crop injury.
x Where sprinkler distribution patterns do not overlap sufficiently, unacceptable weed control may result. 
Where sprinkler distribution patterns overlap excessively, crop injury may result.

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) maintain 15 to 45 psi at nozzles, 2) provide sufficient agitation in tank to 
keep mixture in suspension, and 3) 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 gallons per minute per 100 gallon 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 the suction side 
of the 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 in inches X broadcast rate = amount needed
row width in inches per acre

SPRAY DRIFT MANAGEMENT REQUIREMENTS
SPRAY DRIFT
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 mph at the application site.
x Do not apply during temperature inversions.
x User must maintain a 15 foot (4.6 m) in-field downwind buffer (in the direction in which the wind is blowing) 
from the edge of streams and rivers as well as the 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.
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 po tential 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.
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. 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. 
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 APPLICATIONS
Take precautions to minimize spray drift.

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 one-fourth full with clean water, nitrogen solution or complete fluid 
fertilizer. 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) If any dry herbicides are being tank-mixed, add them to the tank 
and allow them to become thoroughly suspended. 6) Then pour this product directly from jug into tank. 7) 
Continue filling tank until 90% full. Increase agitation if necessary to maintain surface action. 8) Add other 
liquid tank mix herbicide(s) after this product is thoroughly suspended. 9) Finish filling tank. Maintain 
agitation to avoid separation of materials. 10) Empty tank as completely as possible before refilling to 
prevent buildup of emulsifiable concentrate residue from possible tank mix herbicides. 11) If an emulsifiable 
concentrate film starts to build up in tank, drain it and clean with strong detergent solution or solvent. 12) 
Clean sprayer thoroughly immediately after use by flushing system with water containing a detergent.
Compatibility Test: To determine the tank mix compatibility of this product with liquid fertilizer, crop oil, 
spreaders, or other 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 liquid 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 compatibility 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 one-fourth teaspoon of a compatibility agent approved for this use (one-fourth 
teaspoon is equivalent to 2 pints per 100 gallons of spray). Cap and shake until mixed. Examples of 
compatibility agents include Compex
®, MIX™, and Unite®.
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 one-half teaspoon to each jar.
For a spray volume other than 25 gallons per acre, change the teaspoons added to each jar as follows:

4. After adding all ingredients, put lids on and tighten. Shake 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 can probably 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 one-half of the compatibility agent to the fertilizer and the 
other one-half 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.

Pennant® Tank-Mix: This product may be tank-mixed with Pennant herbicide to control weeds in 
containerized, field and liner-grown* ornamentals and commercial landscapes. See the Pennant label for 
ornamental species, weeds controlled with this tank-mixture and other information.
* Plants transplanted normally in rows in a nursery or similar area for further growth prior to transplanting 
to final growing place.
Surflan Tank-Mix: On Christmas tree plantings, use this tank-mix for pre-emergence control of weeds 
listed on the Surflan 75W (or Surflan A.S.) and this label. Use on field-grown Conifer species listed on the 
labels for each herbicide plus Alpine fir, Black spruce, Colorado blue spruce, Coulter pine, Engelmann 
spruce, Giant redwood, Grand fir and Veitchi fir.
Broadcast the mixture as a directed spray to the soil surface or as an over-top spray, using 2 to 4 quarts of 
this product and the specified label rate of Surflan 75W or Surflan A.S. Apply in sufficient water per acre to 
uniformly treat the area. Follow over-top sprays with sprinkler irrigation to move the herbicide from leaf 
surfaces to the soil. Remove weed growth before application. Mix weed residues, prunings or trash into the 
soil or remove them before treatment. Soil should be in good tilth and free of clods at time of application. 
Shallow cultivation (1 to 2 inches) after treatment will not reduce weed control. Observe all precautions and 
limitations on this label and Surflan labels.

PRECAUTIONARY STATEMENTS
Hazards to Humans and Domestic Animals
CAUTION: Causes moderate eye irritation. Harmful if absorbed through skin or swallowed. Avoid contact 
with eyes, skin or clothing.
PERSONAL PROTECTIVE EQUIPMENT (PPE)
Wear long-sleeved shirt and long pants, shoes plus socks, and chemical-resistant gloves.
USER SAFETY RECOMMENDATIONS
Users should: 1) Wash hands before eating, drinking, chewing gum, using tobacco or using the toilet. 
2) Remove clothing/PPE immediately if pesticide gets inside. Then wash thoroughly and put on clean 
clothing. 3) 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 enter 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 sand soils where the water table (ground water) is close to the surface and where these 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 pesticide is toxic to aquatic invertebrates. To protect the environment, do not apply pesticide to enter 
or run off into storm drains, drainage ditches, gutters or surface waters. Applying this product in calm 
weather when rain is not predicted for the next 24 hours will help to ensure that wind or rain does not blow 
or wash pesticide off the treatment area. Rinsing application equipment over treated area will help avoid 
run off to water bodies or drainage systems.
USE INFORMATION
Restriction: For use only on Warm Season Turfgrass (e.g., Bermudagrass, Centipedegrass, St. 
Augustinegrass and Zoysiagrass).
Important: Read the entire “ DIRECTIONS FOR USE ” and the “ WARRANTY—CONDITIONS OF SALE ”
before using this product.
This product is a herbicide that should be applied before weeds emerge or following removal of weed 
growth. It controls a wide variety of annual Broadleaf and Grass weeds when used at selective rates in 
agricultural and ornamental crops. Where a range of application rates is given, use the lower rate on
Coarser textured soil and soil lower in organic matter; use the higher rate on Finer textured soil and soil 
higher in organic matter.
To avoid spray drift, do not apply under windy conditions. Avoid spray overlap as crop injury may result.
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 watering. This product is non-
corrosive to equipment and nonflammable.
