ALWAYS CALL A PHYSICIAN IN CASE OF SUSPECTED POISONING 
ATROPINE BY INJECTION IS ANTIDOTAL 
FIRST AID -- If patient has stopped breathing, t..edistely reaove from 
contaainated area, then start artificial respira-tion, preferably by aechanical 
aeans. If swallowed !.mediately dilute the swallowed material by giving large 
quantities of water and induce vomiting by gagging the victim with £ finger or 
blunt object placed on the back of the victim's tongue. Give flUids until 
vaaitus is clear. Never give anything by mouth to an unconscious person. 
Call a physician or the nearest poison control center. If inhaled, remove to 
fresh air. Get medical 9ttention if ~spira!ory irritation occurs. 
For eye contact, flush with large amounts of running water for at least 15 
ainutes. Hold eye-lids apart to insure rinsing of the entire surface of the 
eyes. Get medical attention. For skin contact, remove contaminated clothing 
and tm.ediately wash skin thoroughly for 15 minutes with soap and water. Avoid 
abrading the skin. 
INFORt~TION FOR PHYSICIAN -- Initial measures include removal of secretions, 
aaintensnce of a patent airway and, if necessary, artificial respiration. 
When cyanosis is relieved, atropine aay be administered in large the-apeutic 
doses. repeated as necessary to the point of tolerance. If sympto~ ~arrant 
further treatment, protopam chloride (pral1dox1me chloride, 2-PAM ci.!oride) has 
shown utility as adjunctive therapy. Hever use morphine. Continued absorption 
of the poison may occur. re-sulting in a fatal relapse after initial 
iaprovement; very close supervision of the patient is indicated for at least 48 
to 72 hours. 
IN CASE OF SPILL 
ISOLATE the spill.

SUGARCANE: At planting - For wireworm control, apply 4 quarts DYFONATE 4-ED 
per acre in a 14 inch band on cane rows 60 inches apart. This is equivalent to 
11 to 14-1/2 fluid ounces of DYFONATE 4-ED per 1,000 linear feet of row. Apply 
over the top of sugarcane seed pieces immediately ahead of covering discs. 
SWEET FOTATOES: For control of wireworms and flea beetle larvae, 1 gallon 
DYFONATE 4-ED per acre, broadcast, at planting and into the soil usi~g suitable 
tillage equipment. 
TABLE BEETS: For control of cabbage maggot ~nd garden symphylans, apply 2 
quarts DYFONATE 4-ED per acre, broadcast, prior to planting. Incorporate into 
the soil using suitable tillage equipment. (For garden symphylans only, reduce 
the rate proportionately for band treatments.) 
TOBACCO: For control of wireworms, apply 1 to 2 quarts DYFONATE 4-ED per 
acre, broadcast, prior to bedding and transplanting and incorporate into the 
soil using suitable tillage equipment. 
FLUE CURED TOBACCOS ONLY: DYFONATE 4-ED in combination with TILLAM 6-E 
controls wireworms and certain weeds (see TILLAH 6-E label) in tobacco. Add to 
the spray tank and apply 1 quart DYFONATE 4-ED and 2-2/3 quarts TILLAM 6-E in 
20 to 50 gallons of water per acre (see Appendix I). Use a properly 
calibrated, low-pressure, boom-type sprayer having good agitation. 
lKPORTANT: Refer to both DYFONATE 4-ED and TILLAH 6-E labels for pertinent 
directions for use, and use precautions and restrictions. The soil should be 
well worked and dry enough to permit good soil incorporation. The tank mix 
must be incorporated (mixed) into the soil immediately after application to 
prevent loss of the herbicide by evaporation. Whenever possible, application 
and incorporation should be done in the same operation. Use power driven 
cultivation equipment set to cut to a depth of 3" in light soil and 3" to 4" in 
heavy soil, or a tandem disc set to cut to a depth of 4" to 6". Cross disc at 
right angles for thorough mixing. The bedding operation should follow the 
incorporation as soon as practical. Planting may be done immediately after 
bedding or at a later date; however, to insure long term weed control, the 
crop should be planted as soon as possible after application and bedding. 
TOMATOES: For control of garden symphylans, apply 2 quarts of DYFONATE 4-ED 
per acre, broadcast, prior to planting and incorporate into the soil using 
suitable tillage equipment. (Reduce the rate proportionately for band 
treatments. )

PROCEDURE FOR TESTING THE TANK-MIX COMPATIBILITY OF DYFONATE 4-ED WITH FLUID 
FERTILIZERS AND DYPOkATE 4-£0 WITH HERBICIDES AND WATER OR FLUID FERTILIZERS. 
This procedure is suggested for determining whether DYFONATE 4-ED and a 
apecific fluid fertilizer and/or the specifically approved herbicide(s) may be 
combined for spray-tank application. 
Materials Required: 
a. 
b. 
DYFONATE 4-ED. 
DYFONATE 4-ED/herbicide combinations (EPTAM 7-E, ERADICANE 6.7-E, 
SUTAN + 6.7-E, TILLAM 6-E, Atrazine 80W or 4L, or Bladex 80W or 4L. 
2. Water or fluid fertilizer to be used. 
3. Adjuvant for tank mix - Compex*, Sponto* 168-D, Unite* or equivalent. The 
adjuvant which performs best depends on the specific fertilizer being 
considered. 
4. Two one-quart, wide-mouth glass jars with tops. 
5. Measuring spoons: a graduated cylinder or pipette will provide more 
accurate measurement). 
6. Measuring cup, 8 oz. (237 mI.) 
Procedure: 
1. Add one pint (2 cups or approximately 473 al) of the test water or fluid 
fertilizer to each of the quart jars. 
1. Add adjuvant to one of the jars and mix (see rate tables). 
3. Carefully add the pesticides to each jar (see rate tables) as follows: 
a. If only DYFONATE 4-ED is to be used, add it directly to each jar. 
b. 
c. 
If a tank mix with a herbicide emulsifiabl~ concentrate is to be 
used, add the herbicide first and mix, and then add the DYFONATE 
4-ED. 
• • ••••• • , . If a tank .ix with a herbicide emulsifiable concentrate ana - . wettable powder or flowable formulation is to be used, add and~x.

1) add and mix the wettable powder or flowable foraulation first 
(preaixing these in water prio~ to addition to fluid fertilizer 
often provides a more compatible mix with fluid fertilizer), 
2) Add and .ix the herbicide eaulsifiabe concentrate second, 
3) aDd finally, add the DYFONATE 4-ED. 
Securely close each jar using the top and mix the contents by inverting 
the jar ten tiaes. 
Inspect the mixtures immediately and after standing for thirty ~inutes 
wi thout lllixing. 
Dispose of jar mixea according to disposal statements contained within 
this label. 
A mixture may be incompatible if either of the following conditions is 
observed: 
a. an oil layer or large oil globules are observed, or 
b. sludge or clumps are present. 
If either mixture remains uniform for thirty minutes, the combination may be 
used. Should either mixture separate after thirty minutes, but remix readily 
with teu jar inversious, the combination can be used if good agitation is 
maintained in the spray tank. If nondispersible oil, sludge or cluaps persist, 
the combination DUst not be used. 
If the mixture with the adjuvant stays mixed, or remixes readily to form a 
uniform di.persion, but the one without adjuvant does not, be .ure to use the 
adjuvant in the spray tank. Add the adjuvant first to the water or fluid 
fertilizer at the reca.mended rate. Kin1lllize foaming by using moderate 
agitation.

Tank Mix Directions 
Dyfonate 4ED 
RS.-011990 
1. Fill the spray tank at least 2/3 full of the appropriate carrier fluid. 
Be sure tank is clean and not contaminated with 2,4-D type herbicides, oil 
residue or other .ateriala. 
2. Start agitation and continue moderate agitation throughout mixing and 
application procedures. 
3. Add the proper amount of adjuvant and mix (if adjuvant is to be used). 
4. Next add the Atrazine BOW or 4L or Bladex 80W or 4L (if it ia to be 
combined in the tank) and mix to disperse it thoroughly. 
5. Then add the herbicide emulsifiable concentrate (EPTAM 7-E, ERADICANE 
6.7-E, SUTAN + 6.7-E or TILLAH 6-E and mix thoroughly • 
6. Lastly, add the DYFONATE 4-ED. 
7. Complete fill1ng the remaining portion of the tank with carrier fluid; mix 
thoroughly. 
8. The tank-mix combination should not be left in the spray tank for 
prolonged periods; batches should be mixed and applied the same day. 
NOTE: Constant moderate agitation is required for successful tank-mix 
preparation and application. Avoid excessive agitation which can cause 
tank-mix incompatibility. All return lines to the tank must discharge below 
l1q u id level.
