GENERAL INFORMATION 

THIDIAZURON 4 SC, a harvest aid compound, is used for leaf removal prior to cotton harvest. 

THIDIAZURON 4 SC can be used in aircraft or ground equipment and is easily dispersed in water. 

Several days may pass before effects of treatment may be observed. Low temperature and other 

adverse conditions may require longer times and I or higher dosages for adequate defoliation. 

THIDIAZURON 4 SC diminishes lint staining at the time of harvest and ginning by slowing regrowth. 

USE PRECAUTIONS 

• This product is not to be applied through any type of inigation system. 

The efficacy of THIDIAZURON 4 SC will be diminished if rainfall occurs within 24 hours post application. 

FOliage from treated plants or gin trash is not to be fed to livestock. Do not use immature crops for feed. 

Rotation to the following crops requires the minimum of the specified periods below after the last 

application of THIDIAZURON 4 SC. 

small grains, sorghum, com, or root crops (except calTots, onions or sugar beets) ........... two (2) weeks 

legumes (including alfalfa) or leafy vegetables (except lettuce and spinach) .................... two (2) months 

sugar beets ......... '" ........................................................................................... .four (4) months 

calTots, onions and spinach .................................................................................. nine (9) months 

lettuce ........... , ............ ONLY when soil has been deep-.plowed (12-15 inches) ............ nine (9) months 

To avoid defoliation of and injury to other plant species, prevent spray drift from contacting crops 

other than mature cotton. 

Mixtures with organophosphate producls can increase nonMtarget crop phytotoxicity. Addilional care 

should be exercised when lettuce, cHrus, cantaloupes or any olher edible crops are adjacent to 

THIDIAZURON 4 SC lrealed fields.

• Chemical~resjstant footwear plus socks 

• Protective evewear 

TIME OF APPLICATION 

THIDIAZURON 4 SC defoliant applications are to be made only on mature cotton plants when the 

uppermost harvestable boll is mature. Boll maturity is defined as: 1) when a boll is squeezed between 

thumb and finger, it does not dent; 2) when cutting a cross section with a sharp knife is difficult; 3) when 

seeds in cross section lack liqUid within the seed coat or outer edges of seed coat are light brown; and 4) 

when fully developed cotyledons are present. 

Make applications of THIDIAZURON 4 SC at least five (5) days prior to expected harvest date. 

NOTE: The following conditions will detennine adequate defoliation with THIDIAZURON 4SC: 

• 

• 

• 

Cotton is actively growing 

High relative humidity 

Colton plant leaves are turgid and not desiccated 

CONDITIONS 

Under low nighttime temperatures (below 60°F), this product, when used alone, may provide less than 

expecled defoliation and I or regrowth suppression. For best results, apply this product when overnight 

temperatures will exceed 60°F two to three days before and after application. 

The effects of THIDIAZURON 4 SC on heat or drought stressed coiton having non~turgid leaves and 

extremely waxy leaf surfaces may include reduced defoliation and reduced regrowth suppression. 

THIDIAZURON 4 SC AS A FOLLOW UP DEFOliATION TREATMENT 

Reduced or unsatisfactory defoliation may occur when THIDIAZURON 4 SC is used as a second or follow 

up treatment, except when following a prior THIDIAZURON 4 SC or THIDIAZURON 50WP stand alone or 

tank mixed application with other defoliants. Also, see CONDITIONS. 

CROP OIL f ADJUVANTS USAGE 

Crop oil concentrates (COC's) or penetrating oils approved for agricultural crops have shown to improve 

perfonnance under low nighttime temperatures (60° ~ 65°F) and heat or drought conditions. Follow 

adjuvant label recommendations for proper rates.

• 

Adjuvant usage in the desert Southwest (Le., Arizona and California) is recommended when applying 

THIDIAZURON 4 SC. 

ATTENTION: During periods of high temperature, the use of adjuvants may result in the freezing 

and/or desiccation of leaves. As a result, the use of such compounds is not recommended during 

high temperature periods. 

MIXING INSTRUCTIONS 

1. Fill spray applicator tank with at least one half of the water to be used 

2. Start agitation 

3. Add the appropriate volume of THIDIAZURON 4 SC 

4. Continue agitation and fill tank with the remainder ofthe water 10 be used 

5, Agitation should continue throughout the application 

TANK MIX ADJUVANTS 

To assist in defoUation performance it is recommended, when using a combination of this product and 

organophosphale defoliants in a tank mix, that a compatibility agent or surfactant is also used. Always 

perform a small jar test for compatibility before tank-mixing. 

When tank-mixing, only tolerance-exempt products (pursuant to 40 CFR 180,1001) are permitted for use. 

Follow manufacturers label instructions of the appropriate adjuvant. 

APPLICATION 

Use an adequate volume of water with the recommended amount of THIDIAZURON 4 SC defoliant to 

uniformly and completely cover leaves, For ground equipment, apply 10 - 25 gallon per acre and by air, 

use 3 -10 gallons per acre. Maintain agitation during application. 

Do not allow mixed spray solution to stand ovemight. 

DOSAGE 

Application Rate: Use 0.1-0.2 lb. active ingredient/acre (3.2-6.4 fl. oz.lA). You will be able to make 

applications to 20-40 acres with one gallon of this product. When under low temperatures of 60° - 65°F, 

use the higher rates as specified. 

When defoliating rank cotton, two applications are sometimes required for adequate defoliation. Do not 

make more than two applications, do not use more than 9,6 fluid ounces (0.3 lb. active ingredient/acre). 

ARIZONA ONLY: BOTTOM DEFOLIATION 

THIDIAZURON 4 SC can be used to help reduce boll rot and hard lock caused by moisture retained in 

the canopy, by aiding improved air circulation within the cotton canopy. Base product appUcation timing 

upon the latest date when application equipment will not cause significant crop damage when driving 

applicator through the cotton crop. 

Application Rate: Use 0.05 lb. active ingredient/acre (1.6 fl. oz.lA). 

It is recommended to apply THIDIAZURON 4 SC only to the bottom 1/3 of the plant. 

ARIZONA AND CALIFORNIA ONLY: PRECONDITIONING 

When used as a pre-conditioner seven to ten days before application of other defoliant compounds, this 

product will improve the efficacy of such a defoliant application. Before use, observe all product label 

directions, recommendations and prohibitions on both product's labels.

Application Rate: Use 0.05-0.1 lb. active ingredienUacre (1.6-3.2 f1. oz.lA). 

TANK MIXES OF THIDIAZURON 4 SC AND ETHEPHON CONTAINING COMPOUNDS 

Improved defoliation and improved opening of mature bolls can be achieved by tank mlxmg 

THIDIAZURON 4 SC and Ethephon 61M or its equivalents. For best results, apply to mature cotton plants 

(See Application Timing section of this label). Wait until unopened bolls have reached adequate maturity 

so as to not affect the desired cotton yield. Certified cottonseed producers should consult seed 

companies as to proper boll and seed maturity requirements for their varielies. Low nighttime 

temperatures (if expected to be below 60"F) can reduce defoliation and decrease regrowth suppression. 

Application Rate: Use 0.05-0.2 lb. active ingredienVacre (1.6-6,4 fl. oz.lA) of THIDIAZURON 4 SC along 

wilh t-2 Ibs. active ingredienVacre (32-64 fl. oz.lA) of Ethephon 61M • 

Under conditions of excessive regrowth potential or expected low temperatures, use the higher rates of 

THIDIAZURON 4 SC. 

TANK MIX OF THIDIAZURON 4 SC PLUS ETHEPHON FOR DEFOLIATION ENHANCEMENT: 

To improve defolialion, you may use lower rates (high enough to promote boll opening) of Ethephon 61M 

or its equivalents tank mixed with this product. Following such an application, Ethephon 6TM can still be 

used to promote boll opening. Per year, however, you may use no more than 2.0 lb. a.i.lacre of Ethephon 

61M (approximately 42 fl.oz. of product) across all applicalions. Observe all product label directions, 

recommendations and prohibitions for Ethephon 6TM. 

Applicalion Rate: Use 0.05-0.2 lb. active ingredienUacre (1.6-6,4 fl, oz.lA) of THIOIAZURON 4 SC along 

with 0.25 Ibs. active ingredienUacre (32-64 fl, oz.lA) of Ethephon 6TM. If extreme regrowth or low 

temperatures are expecled, use the higher rates of THIOIAZURON 4 SC. 

TANK MIX OF THIDIAZURON 4 SC WITH TRIBUFOS PRODUCTS (DEF® I FOLEX®) 

When plants to be treated are subject to non-ideal conditions, such as ovemight temperatures below 60"F 

one day previous and three days after applicalion, it is recommended to tank mix this product and OEF® 

61 FOLEX® 6 EC. This combined spray solution will improve regrowth suppression and defoliation. 

Make tank mix applications to mature cotton with at least 60% open bolls to achieve best activity . 

RATE OF APPLICATION forTHlDlAZURON 4 SC - TRIBUFOS TANK MIXES 

THIDIAZURON 4 SC at 1.6 to 6,4 fluid ounces per acre + OEF® 6 at 0.5 - 2.0 pints per acre. 

THIOIAZURON 4 SC at 1.6 to 6.4 fluid ounces per acre + FOLEX® 6 EC at 0.5 - 2.0 pints per acre. 

If extreme regrowth is expected, use the higher rates of THIDIAZURON 4 SC. 

CAUTION: Desiccation may occur when tank mixing Organophosphate defoliants and maximum rates of 

this product dunng extremely high temperatures. 

When under low temperatures of 60" - 65"F, use the higher rates of OEF® 61 FOLEX® 6 EC as specified. 

For lank mix of THIDIAZURON 4 SC and DEF® 61 FOLEX® 6 EC: 

Follow MIXING INSTRUCTIONS, Following the complete dispersion of THIOIAZURON 4 SC, add the 

required amount of OEF® 61 FOLEX® 6 EC to spray tank. Should an additional application of this tank 

mix be necessary, be sure to use no more than a total of 0.3 Ib, active ingredient per acre (9.6 fl,oz.lA) of

IMPORTANT CLEANOUT INSTRUCTIONS 

When tank mlxmg organophosphate defoliants with THIDIAZURON 4 SC, a residue may fann in 

application equipment. This residue can best be flushed out of the spraying system by using a 

commercial tank cleaner when done while residue is still fresh and moist. DO NOT ALLOW 

EQUIPMENT TO DRY BEFORE CLEANOUT. Consul! your state Extension Cotton Specialist for 

recommended tank cleaners and cleaning procedures. 

Tank cleaner and water should be used immediately after application. The entire system including 

nozzles, booms, application tanks, sumps, pumps, and transfer lines should be flushed. Allowing the 

spray solution to dry in the application equipmem. can result in residues that are more difficult to remove. 

Dried residues are extremely difficult to remove. To remove such dried residues, fill the affected 

equipment to capacity with commercial tank cleaner solution and let it remain for 7 days. 

Afterwards, the equipment will need to be thoroughly flushed and rinsed . 

Spray appljcation equipment that has been inadequately cleaned will conlain residue of THIDIAZURON 4 

SC, Such improper cleaning could lead to crop damage in later applications, 

MFC assumes no liability for crop damage due to equipment that has not been properly cleaned.

Copyright Infringement Issues - Amended Labeling 

Dear Ms. Miller: 

It has recently become necessary for Micro Flo to review our labels in light of the 

litigation currently pending between FMC and Control Solutions. As a result of the 

injunction recently granted to FMC against Control Solutions for copyright infringement, 

Micro Flo will be rewriting all of it's own labels that may be in jeopardy due to this ruling. 

This label has been rewritten in an attempt to reduce any copyright claims Bayer 

Cropscience may have on this text. This label used to be identical or substantially 

similar to Dropp SC Cotton Defoliant, EPA Reg. No. 264-700. 

Please find enclosed five (5) copies of the revised subject label, one copy of the "redline" 

from the copyright lawyers showing the changes, and a copy of the basic registrant's 

label. Th'ls amendment does not fall under any PRIA category, 

Your assistance in reviewing this label in a timely manner is greatly appreciated, Should 

you have any questions or comments, please do not hesitate to contact me at 901A32-

5118 or bye-mail at bill washQl!m@.m.!...qofloC:9El}.Qill}y_.~Q.r!J

• Chemical-resistant gloves such as barrier laminate or butyl rubber gloves 

• Chemical-resistant footwear plus socks 

• Protective evewear 

TIME OF APPLICATION 

THIOIAZURON 4 SC defoliant applications are to be made only on mature cotton plants when the 

uppermost harvestable boll is mature. Boll maturity is defined as: 1) when boll is too hard to be dented 

when squeezed between thumb and finger; 2) when culling a cross section with a sharp knife is difficult; 

3) when seeds in cross section lack liquid within the seed coat or outer edges of seed coat are light 

brown, and 4) when fully developed cotyledons are present. 

Make applications of THIOIAZURON 4 SC at least five (5) days prior to expected harvest date. 

NOTE: The following conditions will determine adequate defoliation with THIDIAZURON 4 SC: 

• Callan is actively growing 

• High relative humidity 

• Callan plant leaves are turgid and not desiccated 

CONDITIONS 

THIOIAZURON 4 SC when used alone under low nighttime temperatures (below 60eF) can provide less 

than expected defoliation and I or regrowth suppression. 

THIOIAZURON 4 SC petiormance under low temperature is variable. Temperature should be above 

60eF for 2 - 3 days prior to and following application or reduced defoliation and regrowth suppression can 

be expected.

I 

• 

The effects of THIDJAZURON 4 SC on heal or drought stressed collon having non-turgid leaves and 

extremely waxy Jeaf surfaces may have reduced defoliation and regrowth suppression exhibited. 

THIDJAZURON 4 SC AS A FOLLOW UP DEFOLJATION TREATMENT 

Reduced or unsatisfactory defoliation may occur when THIDIAZURON 4 SC is used as a second or follow 

up treatment, except when following a prior THIDIAZURON 4 SC or THIDIAZURON 50WP sland alone or 

lank mixed application with other defoliants. Also, see CONDITIONS. 

CROP OIL J ADJUVANTS USAGE 

Crop oil concentrates (C~C's) or penetrating oils approved for agricultural crops have shown to improve 

performance under low nighttime temperatures (600 - 65 QF) and heat or drought conditions. Follow 

adjuvanllabel recommendations for proper rates. 

Adjuvant usage in the desert Southwest (Le., Arizona and California) is recommended when applying 

THIDIAZURON 4 SC. 

PRECAUTION: During periods of high temperature adjuvants can cause leaf desiccation and I or 

leaf freezing. Compounds that promote desiccation of leaf tissue are not recommended. 

MIXING INSTRUCTIONS 

1. Fill spray applicator tank at least one half full 

2. Start agitation 

3. Add recommended amount of THIDIAZURON-DIURON EC 

4. Continue agitation and fiJi tank 

5. Agitation should continue throughout the application 

TANK MIX ADJUVANTS 

Use of a surlactant or compatibility agent is recommended when using tank mixes of THIDIAZURON 4 

SC and organophosphate defoliants to improve overall defoliation and aid in tank clean-out. Always 

perlorm a small jar test for compatibility prior to mixing in the spray tank. 

Use only products which are exempt from tolerance under 40 CFR 180.1001. 

Follow manufacturers label instructions of the appropriate adjuvant. 

APPLICATION 

Use a sufficient amount of water with the specified dosage of THIDIAZURON 4 SC defoliant to give 

complete and uniform coverage of leaf surlaces. For ground equipment apply 10 - 25 gallon per acre 

and by air use 3 -10 gallons per acre. Maintain agitation during application. 

Do not allow mixed spray solution to stand overnight. 

DOSAGE 

Use 0.1 - 0.2 lb. active ingredienVacre. One gallon of THIDIAZURON 4 SC will treat 20 - 40 acres. The 

higher rates should be used under low temperature conditions (60 Q 

- 65Q

F). 

When defoliating rank cotion, two applications are sometimes required for adequate defoliation, do not 

make more than two applications, do not exceed a total of 9.6 fluid ounces (0.3 lb. active ingredienUacre). 

ARIZONA ONLY: BOTTOM DEFOLIATION 

THIDIAZURON 4 SC can be used to help reduce boll rot and hard lock caused by moisture retained in 

the canopy, by aiding improved air circulation within the colton canopy. Base product application timing 

Page 5

I 

• 

I 

upon the latest date when application equipment will not cause significant crop damage when driving 

applicator through the cotton crop. 

Apply 0.05 lb. active ingredienVacre of THIDIAZURON 4 SC ( 1.6 fluid ounces/Ac). 

It is recommended to apply THIDIAZURON 4 SC only to the bottom 1/3 of the plant. 

ARtZONA AND CALIFORNtA ONLY: PRECONDtTtONtNG 

THIDIAZURON 4 SC can be used to enhance the activity of a defoliant application by acting as a pre· 

conditioner. Recommended timing is 7 - 14 days prior to the use of other defoliant compounds. Follow 

the second product label recommendations prior to use. 

Apply THIDIAZURON 4 SC at 0.05 - 0.1 lb. active ingredienVacre (1.6 - 3.2 fluid ounces/acre) 

TANK MtXES OF THtDtAZURON 4 SC AND ETHEPHON CONTAtNtNG COMPOUNDS 

Improved defoliation and improved opening of mature bolls can be achieved by tank mixing 

THIDIAZURON 4 SC and Ethephon® 6 or its equivalents. For best results to be obtained apply to mature 

cotton plants (See Time of Application section of this label). Wait until unopened bolls have reached 

adequate maturity not to affect the desired cotton yield. Certified cottonseed producers should consult 

seed companies as to proper boll and seed maturity requirements for their varieties. Low nighttime 

temperatures (if expected to be below GO"F) can reduce defoliation and decrease regrowth suppression. 

Use THIDIAZURON 4 SC at 0.05 - 0.2 lb. active ingredienVacre (1.6 - 6.4 fluid ounces/acre) plus 

Ethephon® 6 at 1 - 2 Ibs. active ingredienVacre (32 - 64 ounces/ acre) 

Under conditions of excessive regrowth potential or expected low temperatures use the higher rates to 

THtDIAZURON 4 SC. 

TANK MtX OF THtDtAZURON 4 SC PLUS ETHEPHON FOR DEFOLtATtON ENHANCEMENT: 

Lower rates of Ethephon® 6 or its equivalents (not high enough to promote boll opening) can be tank 

mixed with THIDIAZURON 4 SC to improve defoliation. Ethephon® 6 can still be used in subsequent 

applications to promote boll opening following tank mix enhancement applications of THIDIAZURON 4 

SC and Ethephon® 6. Follow Ethephon® 6 label instructions and do not exceed the maximum usage

TANK MIX OF THIDtAZURON 4 SC WITH TRtBUFOS PRODUCTS (DEF® f FOLEX®) 

Under less than ideal conditions to improve defoliation and regrowth suppression, tank mixes of 

THIDIAZURON 4 SC and DEF® 6 / FOLEX® 6 EC is recommended. Nighttime temperatures on day of 

application of less than 60"F and for three consecutive days following application are considered to be 

less than ideal. 

Make tank mix applications to mature cotton with at least 60% open bolls to achieve best activity.

Organophosphate defoliants and maximum rates of THIOIAZURON 4 SC when lank mixed during very 

high air temperatures can cause desiccation. 

With ideal nighttime temperatures (65D F) use [ower rates of DEF® 6{ FOLEX® 6 EC and use higher rates 

when less than ideal conditions are anticipated. 

Tank mix of THIDIAZURON 4 SC and DEF® 61 FOLEX® 6 EC instructions: 

Follow MIXING INSTRUCTIONS and after THIDIAZURON 4 SC is completely dispersed THEN add the 

required amount of DEF® 61 FOLEX® 6 EC to spray lank. 

Do not exceed a lolal of 0.3 lb. active ingredient (9.6 fluid ounces) of THIDIAZURON 4 SC per acre if a 

second application of the labeled tank mix is required. 

Refer 10 DEF®6 and FOLEX® 6 EC labels for use directions and cautions concerning Ihose products and 

tank mixing compatibility W'lth THIDIAZURON 4 SC. 

DO NOT USE TANK MIX OF THIDIAZURON 4 SC WITH DEF® 6 OR FOLEX® 6 EC IN STARR, 

HIDALGO, WILLACY, AND CAMERON COUNTIES OF TEXAS. 

IMPORTANT CLEANOUT INSTRUCTIONS 

When tank mixing organophosphate defoliants with THIDIAZURON 4 SC, a residue may form in 

application equipment. This residue can best be flushed out of the spraying system by using a 

commercial tank cleaner when done while residue is still fresh and moist. DO NOT ALLOW 

EQUIPMENT TO DRY BEFORE CLEAN OUT. Consult your State Extension Coiton Specialist for 

recommended tank cleaners and cleaning procedures. 

Tank cleaner and water should be used immediately after application. The entire system including 

nozzles, booms, application tanks, sumps, pumps, and transfer lines should be flushed. A!lowing the 

spray solution to dry in the application equipment can result in residues that are more difficult to remove. 

Dried residues are extremely difficult to remove and require commercial tank cleaner to remain in 

equipment filled to capacity, for 7 days and then thoroughly ftushed and rinsed. 

Spray application equipment that has been inadequately cleaned will contain residue of THIDIAZURON 4 

SC. This residue may be released during subsequent applications that could cause damage to 

subsequent crops. 

MFC assumes no liability due to equipment that has not been properly cleaned.
