APPLICATIO"I PROCEDURES 
Ground Application: Use conventional ground s?rayers equipped with nozzles that 
provide accucate and uniform application. Be cerLain that nozzles are uniformly 
sp~ced and are the Same size. Calibrate sprayer before use and recalibrate at 
the start of each season and when changing carriers. Unless ot~erwise spec­
ified, use a minimum of 10 g31ions of spray mixture per acre for all preplant, 
rreem~rgence, and postemer~ence applications (with or witbout oil or surfactant) 
~ith gr0unli equipment. 
Use a pu~p with a capacity to (1) maintain 35-40 psi at nozzles, (2) ,ovide 
sufficient agitation in tank to keep mixture in suspension, and (3) t. provide a 
minimllm of 20% bypass at all times. Use centrifugal pumps which provide ~ro­
p~ller shear action for dispersing and mixing this product. The pump should 
pruvide a minimum of 10 gallons per minute per 100 gallons tank size circulated 
through (l correctly positioned sparger tube or jets. 
Us~ scr~ens to protect the pump and to prevent nozzles ~[om clogginF. Scr ·ens 
placed on the suction side of the p'Jmp shl " 1 be 16-mesn or coarser. Do not 
place a scre~n in the recirculation line. Use 50-mesh or coarser screens be­
tween the pump and boom, and where required, at the nozzles. Check n~zzle manu­
facturer's recommendations. 
Fvr band applications, calculate amount to be applied 
band width in inches x broadcast rate = 
row width in inches per acre 
per acre as follows: 
amount needed 
per acre of fie~d 
Aerial Application: Use aerial application only where broadcast applications 
are specified. Apply in a minimum of 1 gallon of water for each pound of 
ATRAZINE 80W applied per acre. For postemergence treatments on corn &I •• i sorghum, 
a,ol~ recommended rate in a minimum of 2 gallons ryf water p.t ~c'e. Avoid 
applic&tinns under conditions where uniform coverage ca~not b~ o~tained or wt,ere 
excessive spray drift may occur. 
Avoid c!pplication to humans or animals~ Flagmen and loaders :,ho.Jld avoid inh.n­
latinn of spray mist and prolongc(l contact with skin and shollld wash ttltJJ'oughly 
before pat tng and at the end qf each d.ay's operc1.tion.

Table 1: Braadleaf and Grass Weed Control in Corn* 
FOR ALL SOIL APPLICATIONS PRIOR TO CROP EMERGENCE 
On Highly Erodible Soils (as defined by SCS) 
If conszrvation tillage is practiced, leaving at least 30% of the soil 
covered ~ith plant res~dues at planting, apply 2.5 lbs.fA as a broadcast 
spray. 
If the soil coverage with plant residue is less than 30% at planting, a 
maximum of 2 lbs.fA may be applied. 
On Soils Not Highly Erodible 
Apply 2.5 lbs.fA 3S a broadcast spray. 
FOR POSTEMERGENCE APPLICATION 
If no atrazine was applied prior to corn emergence, a~~ly 2.5 lbs.fA 
br02Jcast spray. If a postemergence treatment is required following an 
earlier herbicide application, the total atrazine applied may not exceed 
3.1 lbs. er acre per calendar year. 
*Broadleaf control (eastern CO, western KS, weSl~rn NE, NM, OK Panhandle, west 
TX and eastern WY). On sand, sandy loam, mild to strongly alkaline soil, and 
all recently leveled soil, apply no more than 1.5 IbfA, either preplant or 
preemergence. On the other soils in these areas, apply rate in Table 1 for 
broadleaf and grass control. 
Postemergence with Emulsifiable Oil or Oil Concentrate in Water: Add 1 gal. of 
emulsifiable oil per acre for ground application, or 0.5 gal. per acre for 
aerial application, or add 1 qt. of oil concentrate, such as Prime Oil or Prime 
Oil II, per acre for ground application, or 1 pt. per acre for a_rial applica­
tion.

Precautions for all applications to corn: (I) The maximum a~plication rate for 
corn is 3.1 Ibs. per acre per calendar year. (2) Follo~ing harvest, plo~ 
(moldboard or disk-plo~) and thoroughly till soil in fall or spring tc minimize 
possible injury to rotational spring-seeded crops, 
regardless of rate used. 
Note for all Applications to Corn: Do not graze or feed forage from treated 
.reas for 21 days following application. 
ROTATIONAL CROPS: I) Do not rotate to any crop except corn 0' sorghum until 
th~ following year, or injury may occur. 2) If applied after Jun p 10, do not 
rotate with crops otter than corn or sorghum the next year, or crop injury may 
occur. 3) In the Bigh Plains and Intermountain area~ of the We.t where rain­
fall is sparse and erratic or where irrigation is required, use only when corn 
r sorghum is to follow corn or sorghum or when a crop of untreated corn or 
, )rghum is to precede other rotational crops. 4) In eastern parts of the 
Dakotas, KS, western M)I, and NE., do not rotate to soybeans if tLe rate applied 
to corn or sorghum was more than 2.5 Ib/A or equivalent band application rate, 
or soybean injury may occur. 5) Injury may occur to soybeans planted the year 
following application on soils having a calcareous surface layer. 6) Do not 
plant sugar beets, tobacco, vegetables (including dry beans), spring-seed~d 
small grains, or smal~ seeded legumes and grasses the year following applica­
tion, or injury may occur. 
SORGHU:1 AND SORGHUM-SUDAN HYBRIDS 
(Grain and Forage Types) 
Prcplant (Broadleaf and grass control): Broadcast in spring after plowi~g at 
,ate in Table 3. Apply before, during, or after final seedbed preparation. If 
soil is tilled or worked after application, avoid deep incorporation. For best 
results, apply within two weeks prior to planting. 
Preemergence (Broadleaf and grass control): Apply during or shortly after 
planting, but prior to weed or crop emergence at rate in Table 3.

Table 3: Broadleaf and Grass Weed Control in Sorghum* 
FOR ALL SOIL APPLICATIONS PRIOR TO CROP EMERGENCE 
On Highly Erodible Soils (as defined by SCS) 
If conservation tillage is practiced, leaving at least 30% 
of the soil covered with plant residue. at planting, apply 
2.5 Ibs.fA as a broadcast spray. 
If the soil coverage with plant residue is less than 30% 3t 
planti~g, a maximum of 2 Ibs.fA may be applied. 
On Soils not Highly Erodible 
Apply 2.5 lbs.fA as a broadcast spray. 
FOR POSTEMERGENCE APPLICATION 
If no atrazine was applied prior to sorghl.m emergence, apply 
2.5 lbs.fA broadcast. If a postemergence treatment is 
required following an earlier herbicide application, the 
total atrazine applied may to exceed 3.1 lbs. per acre per 
calendar year. 
*Do not apply preplant in AL, AR, FL, GA, LA, MS, NC, NM, OK, SC, TN or TX. 
Do not apply preemergence 1n NM, OK, or TX, except in northeast OK, and the 
TX Gu If Coas t •

In case of planting failure, sorghum or corn may be replanted. Do not make a 
second broadcast application, or injury may occur. If originally applied in a 
band and sorghum or corn is replanted in untreated row middles, this product may 
be applied in a band to the second planting. Ho~ever, the maximum application 
rate for sorghum is 3.1 IbfA per calendar year. 
Preemergence broad leaf weed control in furrow irrigated bedded sorghum (AZ and 
CA only): For preemergence control of many broad leaf weeds, broadcast 1-1.5 
lb. per acre after bed preparation during or after planting, but before sorghum 
and weeds emerge and before the first furrow irr'gatinr. Follow with several 
regular irrigations, making sure to thoroughly wet al_ soil. 
Precautions for Preemergence Application to Furrow Irrigated nedded Sorghum in 
AZ and CA: To avoid possible sorghum injury, do not use on sar.d ~r 10ilm'y';.1nd 
soil or on sorghum planted in furrows. Applications to sorghum ~ro~in'.0/I,

Postemergerlce (BrUil[ll~il( Hnd ~rilss control): Apply at rate in 'fable) bef()re 
weeds exceed 1.5 inches in hpight. Postemergence application to sorghum must be 
mad~ before sorghum r~"ches 12 inches in height. 
Postemergenc~ P.roa!leaf Weed Control with Emulsifiable Oil or Oil Concentrate in 
Water: Broadcast 1.5 Ih/A for control of many broad leaf weeds. Apply before 
pigweed and lambsquarters reach 6 inches in height and before all other weeds 
reach 4 inches in height. In CO, western KS, NM, uK, TX and desert regions of 
AZ and CA, apply when sorghum is 6-12 inches in height. Do not apply after 
sorghum reaches 12 inches in height. In all other areas, apply after sorghum is 
comp!etely emerged, but before ·orghum reaches 12 inches in height. Add 1 gal. 
of emulsifiable oil per acre for ground application and 0.5 gal. per acre for 
aerial application, or add I qt. per acre of oil concentrate, such as Prime Oil 
or Prime Oil II, for ground application, or 1 pt/A for aerial application. A 
cultivation may be ne~essary if all weeds are not controlled or if weeds regrow. 
For a list of weeds controlled, s~e ATRAZINE SOW Applied Alone--Corn or Grain 
Sorghum--Postem~rgence with Emulsifiable Oil or Oil Concentrate in Water. 
Precautions for Applicatiuns with Emulsifiable Oil or Oil Concentrace in Water: 
See Precautions for Applicati~ns with Emulsifiable Oil or Oil Concentrate in 
Water in Corn section. 
~---------------------------------------------------
Postemergence Broadleaf Weed CJntrol with Surfactant (CO, western KS, ~~, OK, 
TX, and desert regi)ns of AZ and CA only): Broadcast 1.5 Ib/A plus 0.75-1.5 pt. 
of surfactant after sorghum reaches 6 inches in height, but before wfeds exceed 
1.5 inches in height. Apply only on sandy loam and finer textured soil. 
Precautions for All Applications to Sorghum: (1) Heavy rain immediately 
following application tends to cause excess~ve concentration of herbicide in 
seed furrow, resulting in possible crop injury. Do not apply to furrow-planted 
sorghum until furrows are leveled (plowed in). Level deep planter marks or seed 
furrows before application. (2) Application to sorghum growing under stress 
caused by minor element deficiency or to sorghum growing on highly calcareous 
soil may result in crop injury. (3) Following harvest, plop (moldboard or 
disk-plow) and thoroughly till soil in fall or spring to minimize possible 
injury to spring-seeded rot3tional crops, regardless of rate used. (4) Injury 
may occur if both this heruicide, preplant or preemergence, and an at-planting 
systemic insecticide applied in-furrow are used. ______________ _ 
Note: Do not graz~ or feed forage from treated areas for 21 days following 
application.
