mediately 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
Atrazine can travel (seep or leach) through soil and can enter ground
water which may be used as drinking water. Atrazine has been found
in groundwater. Users are advised not to apply atrazine to Sand and
Loamy sand soils where the water table (groundwater) 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 groundwater.
This product must not be mixed or lOaded within 50 feet of intermit
tent streams and rivers, natural or impounded lakes and reservoirs.
This product must not be applied aerially or by ground within 88 feet
of the points where field surface water runoff enters perennial or
intermittent streams and rivers or within 200 feet around natural or
impounded lakes and reservoirs. If this product is applied to highly

GENERAL INFORMATION
ATRAZINE 80 Herbicide will control most annual Sroadleaf and Grass
weeds in Corn. Sorghum, Sugarcane and certain other crops as specified
on this label. This product may be applied before or after weeds
emerge.
In each case where a range of rates is given, the lower rate should
be used on Coarse textured soil and soils low in organic matter and
the higher rate should be used on Fine textured soil and soils high in
organic matter. Following many years of continuous use of this product
and chemically related products, biotypes of some of the weeds listed
on this label have been reported which cannot be effectively con
trolled by this and related herbicides. Where this is known or sus
pected and weeds controlled by this product are expected to be present
along with resistant biotypes, we recommend the use of this product
in 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. Consull with your State Ag
ricultural Extension Service for specific recommendations
Since this product acts mainly through root absorption, its effec
tiveness depends on moisture to move it into the root zone. Should
weeds develop, a shallow cultivation or rotary hoeing will generally
result in better weed control
This product is non-corrosive to equipment and metal surfaces, has
low electrical conductivity and is non-flammable. AVOid using this product
near adjacent desirable plants or in greenhouses or injury may occur.
To avoid spray drift, do not apply under windy conditions. Avoid spray
. overlap, as crop injury may result. .
Note: The Seller does not recommend the use of this product in
combination with other herbicides or oils except as specifically de
scribed on the label or in literature published by the Seller.
FAILURE TO FOLLOW THE DIRECTIONS FOR USE AND PRECAU
TIONS ON THIS LABEL MAY RESULT IN POOR WEED CONTROL,
CROP iNJURY OR ILLEGAL RESIDUES.
00 not apply this product through any type of irrigation system
SPRAY DRIFT MANAGEMENT
Avoiding spray at the application site is the responsibility of the applicator. The
interaction of many equipment- and weather-related factors determine the
potential for spray drift. The applicator and the grower are responsible for
considering all these factors when making decisions.
The following drift management requirements must be followed to avoid off
target drift movement from aerial applications to agricultural field crops. These
requirements do not apply to forestry applications, public health uses or to
applications using dry formulations.
1. The distance of the outermost nozzles on the boom must not exceed three
fourths the length of the wingspan or rotor.
2. Nozzles must always point backward parallel with the air stream and never
be pointed downwards more than 45 degrees.
Where states have more stringent regulations, they should be observed
The applicator should be familiar with and take into account the information
covered in the Aerial Drift Reduction Advisory Information section below.
Aerial Drift Reduction AdviSOry Information
Information on Droplet Size
The most effective way to reduce drift potential is to apply large droplets. The
best drift management strategy is to apply the largest droplets that provide
sufficient coverage and control. Applying larger droplets reduces drift potential,
but will not prevent drift if applications are made improperly, or under
unfavorable environmental conditions (see Wind, Temperature and Humidity,
and Temperature ·Inverslons).
ContrOlling Droplet Size
Volume - Use high flow rate nozzles to apply the highest practical spray
volume. Nozzles with higher rated flows produce larger droplets.
Pressure· Do not exceed the nozzle manufacturer's recommended pressures.
For many nozzle types, lower pressure produces larger droplets. When
higher flow rates are needed, use higher flow rate nozzles instead of
increasing pressure
Number of nozzles - Use the minimum number of nozzles that provide
uniform coverage.
Nozzle Orientation - Orienting .nozzles so that the spray is released parallel
to the airstream produces larger droplets than other orientations and is the
recommended practice. Significant deflection from horizontal will reduce
droplet size and increase drift potential.
Nozzle Type- Use a nozzle type that is designed for the intended application.
With most nozzle types, narrower spray angles produce larger droplets
Consider using low-drift nozzles. Solid stream nozzles oriented straight back
produce larger droplets than other nozzle types
Boom Length
For some use patterns, reducing the effective boom length to less than three
fourths of the wingspan or rotor length may further reduce drift without reducing
swath width
Application Height
Applications should not be made at a height greater than 10 feet above the top
of the largest plants unless a greater height is required for aircraft safety.
Making applications at the lowest height that is safe reduces exposure of
droplets to evaporation and wind.
Swath Adjustment
When applications are made with a crosswind, the swath will be displaced
downwind. Therefore, on the up and downwind edges of the field, the applicator
must compensate for this displacement by adjusting the path of the aircraft
upwind. Swath adjustment distance should increase, with increasing drift
potential (higher wind, smaller drops, etc).
Wind
Drift potential is lowest between speeds of 2 to 10 mph. However, many factors,
including droplet size and equipment type determine drift potential at any given
speed. Application should be avoided below 2 mph due to variable wind direction
and high inversion potential.
Note: Local terrain can influence wind patterns. Every applicator should be
familiar with local wind patterns and how they affect spray drift.
Temperature and Humidity
When making applications in low relative humidity, set up equipment to produce
larger droplets to compensate for evaporation. Droplet evaporation is most
severe when conditions are both hot and dry
ATRAZ1NE 80 Page 2 of 10

Temperature Inversions
Applications should not occur during a temperature inversion because
drift potential is high. Temperature inversions restrict vertical air mixing,
which causes small suspended droplets to remain in a concentrated
cloud. This cloud can move in unpredictable directions due to the
light variable winds common during inversions. Temperature inversions
are characterized by increasing temperatures with altitude and are
common on nights with limited cloud cover and light to no wind. They
begin to form as the sun sets and often continue into the· morning.
Their presence can be indicated by ground fog; however, if fog is
not present, inversions can also be identified 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.
Sensitive Areas
This pesticide should only be applied when the potential for drift to
adjacent sensitive areas (e.g. residential areas, bodies of water, known
habitat for threatened or endangered species, non-target crops) is
minimal (e.g. when wind is blowing away from the sensitive area).
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 are 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 10 gallons of spray
mixture per acre for all pre-plant incorporated, pre-plant surface. pre
emergence and post-emergence applications (with or without oil surfac
tant) with ground equipment.
Use a pump with capacity to: 1) Maintain 35 to 40 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 dispers
ing and mixing this product. The pump should provide a minimum of 10
gallons per minute per 100 gallon tank size circulated through a correctfy
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 Goarser screens between the pUI1lP and boom and where
required, at the nozzles. Check nozzle manufacturer's recommenda
tions.
For band application, calculate the amount to be applied per acre as
follows·
Band width in inches x broadcast rate amount needed
Row width in inches per acre per acre in field
Aerial Application: Use aerial application only where broadcast applications
are specified. Apply in a minimum of 1 gallon of water for each
pound of this product applied per acre. For post-emergence treat
ments on Corn and Sorghum, apply recommended rate in a mini
mum of 2 gallons of watE!r per acre. Avoid applications u.nder condi
tions where uniform coverage cannot be obtained or where exces
sive spray drift may occur. Avoid application to humans or animals.
Flagmen and loaders should avoid inhalation of spray mist and pro
longed contact with skin.
THIS PRODUCT IN WATER OR LIQUID FERTILIZER APPLICATIONS
Nitrogen solutions or complete liquid fertilizers may replace all or
part of the water as a carrier for pre-emergence and pre-plant
applications of this product on Corn and Sorghum. Check the com
patibility of this product with liquid fertilizer and/or nitrogen solution
as shown below before use. Do not apply in nitrogen solution or complete
liquid fertilizer after Corn or Sorghum emerges, or crop injury may
occur
Compatibility Test: Since liquid fertilizers can vary, even within the
same analysis, always check compatibility with herbicide(s) each time
before use. Be especially careful when using complete suspension
or fluid fertilizers as serious compatibility problems are more likely
to occur. Commercial application equipment may improve compat
ibility in some instances.
The following test assumes a spray volume of 25 gallons per acre.
For other spray volumes, make appropriate changes in the ingredients
Check compatibility using this procedure:
1. Add 1 pint of fertilizer to each of 2 one-quart jars with tight lids
2. To one of the jars, add 0.25 teaspoon or 1.2 milliliters of a compat
ibility agent approved for this use, such as Compexi' or Unitel>
(0.25 teaspoon is equivalent to 2 pints per 100 gallons of spray)
Shake or stir genlly to mix.
3. To both jars add the appropriate amount of herbicide(s). If more
than one herbicide is used, add them separately with dry herbi
cides first, flowables next and emulsifiable concentrates last. After
each addition, shake or stir gently to thoroughly mix. The appro
priate amount of herbicides for this test follows·
Dry Herbicides: For each pound to be applied per acre, add 1 5
level teaspoons to each jar.
Liquid Herbicides: For each pint to be applied per acre, add 0.5
teaspoon or 2.5 milliliters to each jar.
4. After adding all ingredients, put lids on and tighten and invert
each jar ten times to mix. Let the mixtures stand 15 minutes and
then look for separation, large flakes, precipitates, gels, 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 re-mixed readily,
the mixture 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 one-half of the compatibility agent to the fertilizer and the
other one-half of the emulsifiable concentrate or flowable herbi
cide before addition to the mixture. If incompatibility is still ob
served, do not use the mixture.
THIS PRODUCT PLUS EMULSIFIABLE OIL OR OIL CONCENTRATE
Adding emulsifiable oil (petroleum-derived, petroleum-derived oil
concentrate or single or mixed crop-derived oil concentrate) to post
emergence water-based sprays in Corn and Sorghum may improve
weed control. However, under certain conditions, the use of either
type of oil may seriously injure the crop. To minimize this possibil
ity, observe the following directions
Use one of the following properly emulsified:
1. A suitable oil concentrate containing at least 1 % but not more than
20% suitable emulsifier or surfactant blend.
2. Petroleum-derived oil containing at least 1% suitable emulsifier.
Note: In the event of a compatibility problem when mixing oil with
this product and water, a compatibility agent such as Compex or
Unite should be used. Any of the above oils contaminated with water
or other materials can cause compatibility problems andlor crop injury
MIXING PROCEDURES (All Uses)
1. Be sure sprayer is clean and not contaminated with any other
materiats or crop injury or sprayer clogging may result
2. Fill tank one-fourth full with clean water, nitrogen solution or complete
liquid 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. Drop the unopened pack of this product directly into the tank
8. Continue filling tank until 90%·full. Increase agitation if neces
sary to maintain surface action
7. Add emulsifiable oil, oil concentrate or tank mix herbicide(s) af
ter this product is thoroughly suspended.
8. Finish filling tank.
9. Empty tank as completely as possible before refilling to pre
vent buildup of oil or emulsifiable concentrate residue. Maintain
agitation to avoid separation of materials
10. If an oil or 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 sys
tem with water containing a detergent.
