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.

· .

• 4 - 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 geination, such as low temperatures, lack of soil surface moiature, or when gelnation extends over a long period, the effectiveness of the herbicide may be impaired. Rotary hoeing, a ahallow cultivation or a po.teergenee 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. OBSVE 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 (disaolvd) 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.
14. Tank Hix Compatibility Evaluation Procedure
15. Add 1 pint of curler liquid to each of 2 one -quart jars. Hark 1 quart jar "with" and the other "without."
16. 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.
17. 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. Gallons Liquid Carrier per acre 15 20 25 30 40 Teaspoons of EXTRAZINE 110DF per Pint of Liquid Carrier 1-1/2 1-1/4 1 3/4 1/2

, , ( (

• 7 - 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.
8. 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.
9. 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. ,_ 1· ...

• 8 - 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:

, 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. • : ; An 1_' •

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.

• 15 - 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 grund (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.

( c

• 16 - Apply EXTRAZINE llODF alone or with other products according to tile directions for those treatments in the Preeergence 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 sason. 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.
