Under condiions which delay weed germinalion, such as low temperatures, 
lack of so~ surlace moisture, or when germination extends over a long 
period, the effectiveness of the herbicide may be inpaired. Rotary hoeing, 
shallow cultivation or a postemergence herbicide treatmenf may be 01 
beneli under these circumstances. 
If the crop is cuhivated, tillage should be s'~llow to minimize herbicide 
dilAion in the soi. Should the crop stand be lost due to adverse weather 
condiions, insects, etc., the lield can be replanted the same season to corn 
or sOlghum. 
To enhance weed control in areas 01 less than 25 inches 01 rainfal or where 
long dry periods are common, these treatments may require shallow incor­
poration with a tool such as a lield cuhivator operated from 5-7 mph. 
Incorporation should not be more than three inches deep to keep Irom 
burying the herbicide. A spike-toothed harrow, deep tiAage disk or roling 
basket device is not recommended lor incorporating EXTRAZINE II. 
When applied as a posf-emergence herbicide, EXTRAZINE II OF is also 
active through loliage as well as through the roots. Yellowing andlor 
stunting of the crop may result Irom this treatment, particularly ~ cold, 
adverse growilg condhions occur aher appication. Extended or extreme

The lolowing gentral mixing instructions ill recommended: 
I. Generll 
1. Unless otherwise specHied, use at least 7.5 gallons 01 water per 
acre lor soil iWlications and at least 15 gallons 01 water per acre 
lor loliar awtications lor al applications with ground equipmert. 
NOTE: SUliciert camer must be used to assure uniorm applica­
tion. Follow label requirements 01 al products used in tank mix 
combinations. 
2. A nhrogen solution or com:>lete liquid lertlizer may replace al or 
pari 01 the water as a carrier lor preernergence or preplart applica­
tion on corn. Do not apply lert~izer mixtures after crop emerges, as 
i~ury may occur. 
3. Always check the tank mix compatibiliy (TMC) 01 this or any other 
lormulation before mixing wilh liquid fertilizer carriers or other 
formulations. A simple but generally reliable TMC evaluation 
procedure has been provided for your use in Step II of these mixing 
instructions. 
4. Start with thoroughly clean equipment. (See the labels of the 
previous compounds used for cleaning instructions.) 
5. Fililhe tank atlea~t 112 fufl with camero Start and maintain consis­
tent agitation thlough all mixing and spraying procedures. Make 
sure the agitation system is working properly and creates a !Wing 
or roling action on the liquid surtace. 
6. Slowly add the recommended amount of EXTRAlINE II OF to the 
tank or inductor. 
7. Fill the tario. to 75 ~rcent capacity with canier. filing and bypass 
lines should be kept below tiquid surlace. Increase tank agdation ~ 
necessary to maintain surtace action. 
8. When desired, awropriate emulsille crop ai, crop 01 concentrate, 
or other fank mix formulations should be added at this tine. Pr&­
slurry these added ingredients before addition, H the compalibilily 
test shows n to be necessary. 
g. Complete fling ta'.~, mairtaining sufficient agjation at altines to 
ensure sllface action. This appies to both spray and nurse tanks. 
10. Tank mixtullls should always be applied immediately after prepara­
tion. H, for any reason, this is not possible, assure that sufficient 
agnation has been provided to r&-mix all products and check for 
complete III-suspension prior to application. 
11. Empty tank as completefy as possible before refilling to prevent 
buildup 01 01 or emulsible concertrate r •• idues when tank mixing

Ths chart is based on 1 pound of EXTRAZINE II OF (0.9 pounds 
active ingredient) per acre in the indicated carrier volumes. 
Intended field use rates are achieved by varying the amount of 
EXTRAZINE II OF. (e.g., lor a field use rate of 3 pounds of 
EXTRAZINE II OF in 15 gallons of carrier per acre, add 4.8 
teaspoons 01 EXTRAZINE II OF to the qua~ jars co,.aining 1 pint of 
conier. Calculation: 3 pounds of EXTRAZINE II 0Fl15 galons of 
carrier per acre = 3 X 1.6 • 4.8 teaspoons of EXTRAZINE II OF per 
pint of camer.) 
4. Let each jar stand on&-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 01 the 
following occur: 
a.Separated phases do not re-mix uniformly. 
b.Sereen/ncule plugging fumps do not disperse. 
c.Precipitate does not r&-suspend readily. 
d.Prec:ipilate sticks tenaciously to the glass. 
5. If none althe above problems OCQJI' in ehher jar, the herbicides 
can, in most cases, be :.afely used in that carrier without a 
cornpaIibility agent. 
6. " problem 4.a or 4.b occurs in the jar marluld "Without" 1M does 
not occur in the jar marIuId "With", the compatibility agent should 
be used. 
7. If problem 4.a or 4.b is s.een in both jars, then the heIbicides and 
carrier are incompalible and should not be used in the same 
spray tank. Alernatively, a different tank mix CDrI';l3f'bifny agent 
can be evaluated. ., ,

use and re-check Irequently during use whenever possible. 
2. Use a pump wllh capacily 10: 
a. Maintain 35 10 40 psi al the nozzles. 
b. Provide sufficient agitation in tank to keep mixture in suspen­
sion. 
c. Provide a minimum of 20 perce"t bypass at all limes. 
3. Use centrilugal punlps which provide sufficient shear ',clion for 
dispersing and mixing this product. The pump should I ,ovide a 
minimum 01 10 gallons/minute/100·gallon tank size circulated 
through the jets 01 a correctly-posilioned sparger tube. 
4. Use screens 10 protect the pump and to prevent nozzles from 
clogg'ng. Screens placed on suction side 01 pump should be to 
to t5 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, SO-mesh screens at the nozzles. Check your 
equipment manufacturer's liter.tur. lor specilic recommenda· 
tions. 
FERTILIZER IMPREGNATION 
EXTRAZINE II OF Herbicide may be applied when coated on or impreg· 
nated in dry granular fertilizer for early preplant, preemergence or preplan! 
incorporated weed control i1 field com. All recommendations, cautions 
and special precautions on this label must be followed along w~h state 
regulations relating to dry bulk lertilizer blending, impregnating and 
labeling. 
Gtneral Blending Directions 
EXTRAZ!NE II OF may be coa!ed on or impregnated in dry bulk lertiizers 
using tower blenders. rotary drum blenders or blending augu's or 
cooveyors. DO NOT impregnate EXTRAZINE II or tank mixes cootaining 
EXTRAZINE II on or in lertilizers containing Ammonium Nitrate. 
Potassium Nitrate. or Sodium Nitrate. Do not use on straight limestone 
since absorption will not be achieved. Fertilizer blends containing 
imestone can be impregnaled When using EXTRAZINE II alone. Use a 
mimmum of 200 Ibs. and a maximum 01 4SO Ibs per acre 01 dry lertil~er. 
Use equipment that will give a unilorm distribution .-1 the herbicide 
throughout elch I,atch 01 impregnaled le~ilizer Non-umlorm imp!egna­
lion can Ct-1U~B crop injUry or unsatisfactory perlormance 
4 
A. EXTRAZ!NE II OF may be used as the only herbidde lor impregnation. 
1. Add EXTRAZINE II OF to 112 the total fertilizer volume required. 
2. Spray one gallon 01 water (to break down OF) and one gallon 01 
diesel fuel (to prevent evaporation and crusting) per ton of ler1ilizer 
and allow to mix thoroughly. NOTE: If the ferti~zer is dusty, add the 
diesel fuel before adding the herbicide. 
3. Add remaining fenil~er and mix thoroughly. (3 minutes or more for 
rotary drum blenders.) 
4. Add 2·3% Ag·Sorb or 1·2% Mp-79 drying a~ent (or a suitable 
amount 01 another eHective drying agent) to insure a spreadable 
herbicicfe.1er1i1izer mixture. The need lor a drying agent is deter· 
mined by the IYPtness of the fer1ilizOf balch. Wetness can change 
with humidity, nnragen content, fertilizer types, fertil~er rates and 
herbicide rates. 
B. EXTRAZINE II DF may be used in tank mixes with other dry herbicides 
including PRINCEP CALIBER 90. Folow the procedure as above in 
aA·, 
C. EXTRAZINE II OF may be used in tank mixes where an EC or other 
iquid herbicide acts as the sticking agent. This may eliminate the need 
for water and/or dieselluel. 
1_ While lerti~zer is blending, add the EXTRAZINE II OF. Experience 
has shown that this will provide the most consistent perlormance 
due to the grinding action of the fertilizer on the 9ODF. 
2. Spray in the EC herbicide and mix thoroughly. (3 minetes or more 
for rotary drum blenders). 
3. Atid drying agent to insure a spreadable herbicidenertiizer mixture. 
Usually less drying agent is required when using EXTRAZINE II OF. 
O. Pre-slurried EXTRAZINE II OF can be used alone or in a tank mix for 
impregnation. For rotary.<Jrum mixers, the liquids can be moved into 
the drum using an air system or liquid pump. Do not add extra water. 
Add drying agent to insure a spreadable herbicidenertiizer mixture. 
(For more inlormation on Drying Agents, Application Equipment. 
Calibration Guide and variations of these methods. see Du Pont Bullelin 
on 'Fertilizer Impregnation'). 
CLEAN OUT: Equipment used to impregnate or apply fertiizer impr!'g­
nated with EXTRAZINE II or combinations including EXTAAZINE II must 
be deaned au by running at least t.OOO Ibs. of fertilizer not impregnated 
with EXTRAZINE II through the impregoation equipment and apptication 
equipment, if the next batch 01 material is to be appied to a crop lor which 
EXTRAZINE II or a combination herbicide is not registered.
