HELEIIA BRAND ATRAZWE HERBICIDE will control mos.t annual broad1eaf 
and grass weeds in corn, sorghum, sugarcane, and certain other crops. 
It is also effective for control of most annual and many perennial 
·broadleaf and grass weeds in noncrop areas and industrial sites. 
HELENA BRAND ATRAZINE may be applied before or after weeds emerge. 
Since HELENA BRAND ATRAZINE acts mainly through root· absorption, its 
effectiveness depends on rainfall or irrigation to move it into root 
zone. Should weeds develop, a shallow cultivation or rotary hoeing 
will generally result in better weed control. 
HELENA BRAND ATRAZINE is a wettable powder that should be mixed with 
water and applied as a spray. MaKe a slurry by adding HELENA BRAND 
ATRAZINE to water. Pour the slurry into the spray tank during or 
after filling. Sufficient hydraulic (jet) or mechanical agitation 
must be provided during mixing and application to keep the material 
in suspension. 
Wash sprayer thoroughly after use. 
Care should be taken to avoid using HELENA BRAND ATRAZINE where 
adjacent desirab)e trees, shrubs, or plants might be injured. 
Store HELENA BRAND ATRAZINE in a dry place. 
In each case where a range of rates is given, the lower rate ~hould 
be used on light soils and soils low in organic matter; the higher 
rate should be used on heavy soils and soils high in organic matter. 
GROUND APPLICATION: For uniform distribution in broadcast applications, 
TeeJet 8003 or 8004 fan type or similar nozzles with openings of equal 
or greater size should be used. For band applications, use TeeJet 
8003-E or 8004-E or similar type nozzles. Screens in nozzles as well as those 
in suction and in-line strainers should be no finer than 50 mesh size. 
A suitable pump with capacity to deliver 10-12 gpm should be used and 
operating pressure should be 35-40 psi. Use 20-40 gals. of water 
per acre to assure even coverage unless otherwise specified. 
AERIAL APPLICATION: Use only where broadcast· app-l ications a~· specified. 
Apply a minimum of 1 gallon of water for each"]" lb. to 1 1/2 lbs. of 
HELENA BRAND ATRAZINE to be applied per acre. 
Avoid application under conditions where uniform coverage canr.ot be 
obtained or where excessive-spray drift may occur . 
. (flSTRUCTIONS FOR SAFE HANDLING - Avoid appl ication directly to humil'ols 
or animals. 
"For combining with HELENA BRAND ATRf.ZINE, use a crop oil desigriatl!d for 
use with Atrazine containing at least 1 percent suitable efI'Iuls-ifier

Several oils of this type are on the market. Oils contaminated I~ith 
I~ater 0" other materials can cause compatibility problems and or crop 
injury, Observe all cautions and 111"ltations on labeling of all pro­
ducts used in mixtures. 
,-IIOCEDURES: 1) Thoroughly clean sprayer prior to use. 00 not use 
sprayer contaminated with 2.4-0 or other materials as corn damage or 
sprayer clogging may result. 2) In a separate container, make a 
thin slurry of HELENA BRAND ATRAZINE in water. thoroughly wetting 
the Atrazine. J) Fill the spray tank with water. allowing for the 
addition of the HELENA BRAND ATRAZINE. 4) With the agitation 
system in operation. add the Atrazine slurry. 5) Add the emulsifiable 
oil last, 6) Empty the tank as completely as possible before refilling 
to prevent a buildup of oil in the tank. Keep the agitation system in 
operation to avoid separation of the oil from -the water in the spray 
mixture still remaining in the tank. 7) If an oil film starts to build 
up in the tank drain the tank and clean out with a strong detergent 
solution or solvent. 8) Clean the sprayer THOROUGHLY immediately 
after use by flushing the system with watpr containing a detergent. 
NOTE: 1) Do not use oil in Atrazine sprays when corn is under stress 
from prolonged cold, wet weather. poor fertility, or other factors, or 
\~hen corn is wet and succulent from recent rainfall as crop injury may 
occur. 2) Do not use oil in sprays when treating inbred lines or any 
breeding stock as .injury may occur. 3) Adding other insecticides. 
herbicides. liquid fertilizers. or other materials is not reconmended 
I~i th Atrazine and emulSifiable oil in water because they may cause 
compatibility problems or crop injury. 4) Store and handle emulsifiable 
oil carefully. Oil contaminated with even a small amount of water may not 
emulsify properly when added to the tank. 5) Do not make more than one 
application of HELENA BRAND ATRAZINE and emulsifiable oil in water per 
season. 
NORTHERN NUTGRASS OR YELLOW NUTS EDGE (Cyperus esculentus) CONTROL: 
Broadcast 5 lbs. per acre preplant. pre-emergence. or post-emergence 
before nutgrass is more than 1 1/2 Inches high. If applied before 
nutgrass begins growth, cultiVate within 2-3 weeks. If applied after 
nutgrass has emerged. cultivate within 10-14 days. 
The maximum application rate of corn is 3 Ihs. a.i. (3-3/4 lb. ATRAZINE 
BOW) per acre per calendar year. Application for quackgrass suppr~ssl~n .

'For combining with Atrazine, use a crop oil designed for use with Atrazine 
containing at least 1 percent suitable emulsifier. Several oils of this 
type are on the market. Oils contaminated with water or other materials 
can cause compatibility problems and/or crop injury. 
PROCEDURES: I} Thoroughly clean sprayer prior to use. Do not use 
sprayer contaminated with 2,4-0 or other materials as sorghum damage or 
spray clogging may result. 2} In a separate container make a thin slurry 
of I/EL[NA BRArw ATRAZIN[ in water, thoroughly wetting the Atpzine. 3} 
Fill the spray tank with water, allowing fo~ the addition of the Atrazine. 
4) With the agitation system in operation. add the HELENA BRAND ATRAZINE 
slurry. 5) Add the emulsifiable oil last. 6} Empty the tank as ,:onrpletely 
.1S possible before refi 1 I ing to prevent a buildup of oil in the tanK. Keep 
the agitation system in operation to avoid a separation af t~e oi~ from the 
,",Her in the spray mixture still remaining in the tank. '7} ;If a,l Jil film 
starts to build up in the tank, drain the tank and clean o~t 'with i .strong 
detergent solution or solvent. 8} Clean the sprayer tho~~~ghly l~ciately

Injury may occur. 2) 00 not use oil in HELENA BRAND AT~ZINE sprays when 
treating inbred lines or any breeding stock as iajury may occur. 3) Adding 
other insecticides, herbicides, liquid fertilizers, or other materials is 
not re~ommended because they may cause compatibility problems or crop injury 
4) Store and han. <! emulsifiable oil carefully. Oil contaminated with even 
a sillall amount of lter may not emulsify properly when added to the tank. 
5) Do not make m ~ than one application of HELENA BRAND ATRAZINE and 
emulsifiable oil . water per season. 
PRECAUTIONS: 1) Heavy rains immediately following application tend. to result 
in excessive concentrations of herbicide in seed furrow, resulting in po>sible 
crop Injury. App1 ications to furrow-planted sorghum should not be made' 
until furrows are leveled (plowed-in). Deep planter marks or seed furrows 
should be leveled before application. 2) Application made to sorghum growing 
under stress cause~ by minor element deficiency or to sorghum growing on 
highly calcareous soils may result in crop injury. 3) 00 not plant any 
rotational crops otl ~r than those specified in the Suggestions for Rotational 
Crops section below for 18 months following application. 4) Do'not graze 
or feed forage from treated areas for 21 days following application. 5) 
Following harvest of a treated crop, plow (moldboard or disk-plow) and 
thoro~gh1y till the soil in fall or spring to minimize possible injury to 
rotational spring-seeded crops, regardless of the rate userl. 
SUGGESTIONS FOR ROTATIONAL CROPS: 1) Sorghum or corn may be planted the year 
following treatment. 2) All other rotational crops may be planted 18 months 
after application. 3) When the broadcast rate used does not exceed 1 1/2 
1bs. per acre, fall wheat may be planted 15 months after application.
