Cyanazine and atrazine, the active ingredients in EXTRAZINE are pesticides 
which can move (aeep or travel) through soIl and can contaminate groundwater 
which may be used as drinking water. Cyanazine and atrazine have been found 
in groundwater aa a result of agricultural use. Users ere advised not to 
apply EXTRAZINE where the vater table (groundwater) is close to the surface 
and where the 80ils are very permeable (i.e. well drained soils such as loamy 
sands). Your local agricultural agencies can provide fur tiler information on 
the type of soil in your area and the location of groundwater. 
Atrazine is toxic to aquatic invertebrates. Do not a;~ly directly to water 
or wetlands. Do not apply where runoff is likely to occur. Do not epply 
when weather conditions favor drift from treated areas. Runoff and drift 
from treated areas may be hazardous to aquatic organisms in neighboring 
areas. Do not contaminate water by cleaning of equipment or disposal of 
wastes.

EXTRAZINE IIODF Herbicide is a selective herbicide for the control of annual 
grasses and broadleaved weeds in field corn, popcorn, and sweet corn. 
Consult your local Agricultural Extension Agent for help in determining soil 
texture, organic matter content, and the most appropriate herbicide rate for 
local conditions. 
Where surfactanta or emulsifiable vegetable oils are added to EXTRAZINE 110DF 
for over the top of corn postemergence applications, use on field corn only.

As a preemergence herbicide, EXTRAtINE 110DF ia active mainly through the 
roots, and therefore, its effect on weeds ia dependent on adequate rainfall 
or sprinkler irrigation to move the herbicide into the root zone. Koi.ture 
should be sufficient to wet the top 1-1/2 to 2 inchea of aoil or make the 
soil too wet to cultivate; for moat aoila, 1/2 to 3/4 inches of moisture i. 
aufficient. A rotary hoeing or ahallow cultivation ia recommanded if a 
rainfall or sprinkler irrigation has not occurred within about ten deys after 
application of EXTRAZINE 110DF. Under conditione which delay waed 
ge~ination, such as low temperatures, lack of soil surface moiature, or when 
ge~lnation extends over a long period, the effectiveness of the herbicide 
may be impaired. Rotary hoeing, a ahallow cultivation or a po.te~ergenee 
herbici,je treatment may be of benefit under these circumstances. \/hen 
applied as a postemergenee herbicide, EXTRAZINE 110DF 1a also active through 
fo11age, as well as through roots. 
EXTRAZINE 110DF is not effective when used preemergenee on peat or muck 
soils. Do not use EXTRAZINE 110DF alone on sands or loamy sands (soils 
·~onsisting of more than 70 percent sand) containing less than 1 percent 
organic matter. 
OBS~VE ALL CAUTIONS AND LIKITATIONS ON LABELING OF ALL PRODUCTS USED IN 
KIXTlJRES. 
Rotational crops: (1) Plant only corn, peanuts, sorghum, or soybeans the 
year following the use of this mixture. (2) If soybeans are to be planted, 
injury may occur due to the carryover of atrazine. (3) If applied after June 
10, do not rotate with crops other than corn or aorghum the next year or 
injury may occur. (4) In the high plains and intermountain areas of the West 
where rainfall is aparse and ~rratic or where irrigation 1~ reqUired, use 
only when sorghum is to be planted the following year, or a crop of corn or 
sorghum not treated with atrazine ia to precede other rotational crops. (5) 
Small grains may be planted 15 montha following treatment. (6) All other 
crops may be planted 18 montha after application. 
APPLICATION DIRECTIONS 
GeDeral Mixing Ind SproyiDI Jng.ruction. 
Use sufficient agitation to en.ute that the EXTRAZINE 110DF il completely 
disperaed (disaolv~d) and in uniform auspenaion prior to application or tank 
mixing with other formulations.

- 5 -
The following general mixing instructions are recommended when using thia or 
any other dry flowable formulation. 
I. General 
1. Unle •• otherwise apecified, use at least 15 gallons of water per 
acre for all applicaticns with ground equipment. For aerial 
application, apply a m!inimWII of 4 gallons of water per acre. 
2. A nitrogen solution or coaplete liquid fertilizer aay replace all or 
part of the water as a carrier for pre emergence or preplant 
application on corn or sorghum. Do not apply fertilizer mixtures 
cfter crop emerges, as injury may occur. 
3. Always check the tank mix compatibility (THC) of this or any other 
formulation before mixing with liquid fertilizer carriers or other 
formulations. A siaple, but generally reliable THC evaluation 
procedure has been provided for your use in step II of these mixing 
instructions. 
4. Start with thoroughly clean equipment. 
5. Fill tank 1/4 full with carrier. Start and maintain consistent 
nitatiQD through all mixing and spraying prs>ceduru. Kake sure 
that the agitation system is working properly and creates a rippling 
or rolling action on the liquid sur~'ce. 
6. Slowly add the dry flowable (DF) to the tank or inductor. 
7. Fill tank to 75 percent cQfacity with carrier. Filling and bypass 
lines "hould be kept b •. low Hquid aurface. lncre .. e tank agitation 
if necessary to maintain surface action. 
8. Vhen desired, appropriate em~lsifiable oil, 011 concentrate, or 
other tank lIix formulations should be added at this tille. Preslurry 
theae added ingredients before r.dditioT. if the compatibility test 
ahovs it to be necesaary. 
9. Co~lete filling tank, .. intaining sufficient agitation at all times 
to ensure aurface action. This appUes to both .pray and nune 
tanks, 
10. Tank mixtures ahould always be applied immediately after 
preparation. If for any reason this 1& not pos8ible, assure that 
sufficient agitation has been provided to remi".t all products and 
check for complete reluspenaion prio~ to application.

I 
...• 
- 6 -
11. Empty tank as completely as possible before refilling to prevent 
buildup of oil or emulsifiable concentrate rasidues when tank mixing 
with these formulations. Always maintain agitation to avoid 
separation. 
12. If an oil or emulsifiable concentrate film starts to build up after 
using these formulations, drain and clean the tank with strong 
detergent solution or appropriate solvent. 
13. It is recommended that the sprayer be thoroughly cleaned by flushing 
with a detergent solution at the end of each work day when any 
emulsifiable oil, oil concentrate, or other emulsifiable formulation 
has been used either alone or in tank mix combinations with other 
pesticide formulations, even if no obvious problems have been 
encountered. This precaution will ensure a clean sprayer and 
continued troublefree operation. 
11. Tank Hix Compatibility Evaluation Procedure 
1. Add 1 pint of curler liquid to each of 2 one -quart jars. Hark 1 
quart jar "with" and the other "without." 
2. Add 1/4 teaspoon of a suitable tank mix compatibility agent (1/4 
teaspoon/pint - 2 pints/lOO gallons of carrier) to the jar marked 
"with," cap the jar, and shake gently for 5 to 10 seconds to mix. 
3. Add the appropriate amount of herbicide to both j ara, cap each jar, 
and shake gently for 5 to 10 seconds to mix. If problems are 
encountered in mixing wettable powder or dry flowable formulations 
into P liquid fertilizer, preslurry these formulations in water 
prior to their addition to the liquid fertilizer and proceed with 
the test. The following chart bas been provided to assist in 
selecting the appropriate EXTRAZINE 110DF use rate for tbis 
evaluation. If more than one herbicide is to be useu in the tank 
mixture, each should be added separately as follows: water soluble. 
first, wettable powders or dry flowables second, liquid flowables 
third, and emulsifiable concentrate or oil formulations last, with 
each jar capped and gently ahaken for 5 to 10 aeconds for eacb 
addition.

This chart is based on 1 pound of EXTRAZINE 110DF (0.9 pounds active 
ingredient) per acre in the indicated carrier volumes. Intended field 
use rates are achieved by varying the amount of EXTRAZINE llODF; i.e., 
for a field use rate of 2.5 pounds of EXTRAZINE 110DF in 15 gallons of 
carrier per acre, add 3.75 teaspoons of EXTRAZINE to the quart jars 
containing 1 pint of carrier. Calculation: 2.5 pounds of EXTRAZINE 
llODF/15 gallons of carrier per acre - 2.5 x 1.5 or 3.75 teaspoons of 
EXTRAZINE 110DF per pint of carrier. 
4. Let each jar stand one-half hour and make observations. If any 
separation, agglomeration, or precipitation has occurred, shake the jar 
again for 10 to 15 seconds, and note whether any of the following occur: 
a. Separated phases do not re. uniformly. 
b. Screen/nozzle plugging luml do not disperse. 
c. Precipitate does not resuspend readily. 
d. Precipitate sticks tenaciously to the glass. 
5. If none of the above problems occur in either jar, the herbicides can, in 
most cases, be safely used without a compatibility agent. 
6. If problems 4. a. or 4. b. occur in the jar marked "without," but do not 
qccur in the jar marked "with,", the compatibility agent should be used. 
7. If problems 4.a. or 4.b. are seen in both ja~s, the herbicides and 
carrier mixture are incompatible and should not be used in the same spray 
tank. Alternatively, a different tank mix compatibility agent can be 
evaluated. 
B. If proolems 4.c. or 4.d. occur in the jar marked "without," but do not 
occur in the jar marked "with," the compatibility agent should be used 
unless constant, thorough agitation can be maintained and immediate 
clean-out of spray system is performed. 
9. If problems 4.c. and 4.d. are seen in the jar marked "with," the user 
proceeds with mixing and application at his won risk should agitation in 
the system be insufficient or curtailed. 
10. Those mixtures defined as compatible in this test should then be mixed 
for use as indicated in Steps 1 through 12 of the general mixing 
instructions listed above.

Ill. Application Equipment 
1. Use application equipment fitted with nozzles that provide 
accurate and uniform coverage. Be certain that nozzles are 
uniformly spaced and the same size. Calibrate sprayer 
before use and recheck frequently during use whenever 
possible. 
2. Use a pump with capacity to: 
3. 
4. 
, 
a. Kaintain 35-40 psi at nozzles. 
b. Provide sufficient agitation in tank to keep mixture 
in suspension. 
c. Provide a minimum of 20 percent bypass at all times. 
Use centrifugal pumps which provide sufficient shear action 
for dispersing and mixing this product. The pump should 
provide a minimum of 10 gallons/minute/100-gallon tank size 
circulated through the jets of a correctly-positioned 
sparger tube. 
Use screens to protect the pump and to prevent nozzles from 
clogging. Screens placed on suction side of pump should be 
10 to 16 mesh. Do not place a screen in the recirculation 
line. Use a 40- to 50-mesh screen between the pump and boom 
and, where required, 50-mesh screens at the nozzles. Check 
your equipment manufacturer's literature for specific 
recommendations.

PREEHERGENCE-PREPLANI INCORPORATEp 
Apply EXTRAZIRE treatments just before, at, or after planting but before crop 
has emerged. Avoid removal of treated soil from seedrow prior to or during 
the planting operation. 
EXTRAZINE may also be applied early prior to planting or in a split 
application if pre-season weed control i. desired. For split applications, do 
not exceed the total amount of EXTRAZINE for the soil texture and organic 
matter shown in Table 1. If EXTRAZ1NE is applied early, more than 15 days 
before planting, a split application of EXTRAZINE or some other herbicide 
treatment may be necessary at or after planting to provide additional length 
of weed control. For further information, see "Early Preplant" 
recommendations in the Conservation Tillage section of this label. 
A rotary hoeing is recommended for preemergence applications which do not 
receive adequate rainfall or sprinkler irrigation to wet the top 1-1/2 to 2 
inches of soil within about 10 days after application. 
-If an EXIRAZINE mixture is to be incorporated, except as noted, single- or 
two-pass incorporation is acceptsble. Care shoUld be taken to incorporate the 
EXTRAZINE Qixture no deeper than the top 2 inches of soil. 
EXIRAZINE Applied Alone

CONSERVATION TILLAGE PEED CONTROL 
Early Preplant (EPP) 
[Prior to planting weed control for land going into production of corn.) 
Complete any planned early spring tillage prior to application. Apply 
herbicide treatment before weeds germinate or before weed seedlings are more 
than 3 inches tall. Tillage after application may reduce the effectiveness of 
the herbicide treatment. 
Apply EXTRAZINE 1100F 15 to 30 days prior to planting. Use the proper rate 
for soil texture and organic ~tter indicat9d in Table 1. Where heavy crop 
residues exist, the rates shown in Table 1 should be increased by 25 percent. 
Where broadleaf weeds are present, add 2,4-0 LV Ester at 1-1/3 to 2 pints per 
acre (6 pounds/gallon) or 2 to 3 pints per acre (4 pounds/gallon) plus X-77 
surfectant at 1 quart/lOO gallons of diluted spray, or other suitable 
surfactant at its recommended rate. When 2,4-0 Ester is tank mixed with 
.EXTRAZINE as previously described, these additional weeds will be controlled: 
Buckwheat, Dandelion, Dock, Harestail, Pennycress, Prickly lettuce, and Tansy 
mustard. If existing annual weeds exceed 3 inches in height, add 1 to 2 pints 
~er acre of paraquat or 2 pints per acre of Roundup to the above mixture. 
Well-established weeds over 6 inches tall may not be well controlled. Use at 
least 25 gallons per acre of spray mixture by ground rig or 5 to 10 gallons 
per acre for aerial application . 
. 
Depending upon weather conditions following the Err application, a 
post-emergence EXTRAZINE or BLADEX Herbicide treatment, or 80me other 
herbiCide treatment may be necessary at or after planting to provide 
additional length of weed control. If desired, 1-1/2 to 2 pints per acre of 
" Dval or 2 quarts per acre of Lasso may be tank-mixed with the EXTRAZINE EPP 
treatment or applied preemergence at planting. 
Rotational Crops: Refer to the General Information section of the label. 
At ?lautin & 
EXTRAZINE 1l0DF appUed alone or in cOlIl',ination with LaBlO or Dual according 
to the following directiona will kill lIoat exiating s .. ll weeda and suppress 
many emerged perennial weeda when corn 1s planted into no-till talk gr~und 
(corn, sorghum), stubble ground (soybean, small grains), and any minimum-till 
aituation. Thia treatment then provides residual control of annual weeds as 
in conventional tillage.

Apply EXTRAZINE llODF alone or with other products according to tile directions 
for those treatments in the Pree~ergence section of the label. Where heavy 
crop residues exist, the EXTRAZINE rate shown in Tables 1 or 2 should be 
increased by 25 percent. Add 1/2 to 1 pint per acre of 2,4-0 Low Volatile 
6-pound Ester (0.75 to 1.5 pint per acre 2,4-D LV 4 pound Ester). Add the 
2,4-D LV to the spray tank last. Refer to the EPP section above for 
additional broadleaf weeds controlled with an EXTRAZINE/2,4-D Ester tank mix 
treatment. Use a minimum of 25 gallons per acre of carrier. Complete spray 
coverage of the weeds is essential for best performance. Nitrogen solutions 
and complete liquid fertilizers are the preferred carriers for this treatment 
as they help aid in the burndown of existing weeds. Add Ortho X-77 surfactant 
at 1 to 2 quarts per 100 gallons of diluted spray, or other suitable 
surfactant at its recommended rate. If water is used as a carrier, crop oil 
concentrate may be used as a surfactant. Apply before weeds exceed 3 inches 
in height. For control of existing alfalfa, add 1/3 to 1/2 pints per acre of 
Banvel w to the spray mixture. Apply before the alfalfa exceeds 6 inches in 
height. 
For fields with existing sod grasses such as orchardgrass, bromegrass, rye, or 
timothy, or when very dry conditions exist, or when existing weeds exceed 3 
.inches in height, add Paraquat CL to the tank-mix. Use 2 pints per acre of 
Paraquat CL in combination with EXTRAZlNE as described above in this section, 
except the 2,4-D LV may be omitted, if desired. Do not apply Paraquat CL in 
suspension-type liquid fertilizer. 
POSTEHERGENCE 
EXTRAZlNE Auolied Alone 
Use EXTRAZlNE 110DF at the proper rate for the soil textur~ and organic matter 
shown in Tables 3 or 3A. Use rates shown in Table 3 if EXTRAZINE or BLADEX 
has not been applied to the soil this s~ason. Use rates shown in Table 3A if 
EXTRAZlNE or BLADEX has been applied to the soil this season. This treatment 
may be used on peat or muck soils for burndown and suppression of existing 
weeds but will not provide residual control. Apply from crop emergence 
througn the four-leaf stage of corn growth before weeds exceed about 1-1/2 
inches in height. Do not apply over the top of corn if the fifth leaf is 
visible. Apply in water only. Do not spray emerged corn plants in a liquid 
fertilizer carrier. 
DO NOT APPLY rnlS TREATMENT UNDER COLD, WET WEArnER CONDITIONS, OR TO WEATHER­
STRESSED OR STORM-DAMAGED CORN. Yellowing of the corn may result from this 
treatment, particularly if cold, adverse growing condit~ons occur after 
application. Extended or extreme cold and wet conditions may reduce stands. 
Do not use on corn grown for seed.
