GENERAL INFORMATION 
Tough 5 EC is a selective herbicide for postemergence control or suppression of 
actively growing annual broad leaf weeds in peanut, field com, seed com, and popcorn. 
Tough 5 EC is recommended to be used sequentially and tank mixed with other 
herbicides as part of a complete weed control program. 
Tough 5 EC is an emulsifiable concentrate formulation containing 5 Ibs. of pyridate per 
gallon of product. 
Biological Activity: Tough 5 EC is a contact herbicide that is absorbed rapidly by the 
leaves of plants. Tough 5 EC does not offer any residual weed control. Therefore, 
weeds must have emerged at the time of application. Symptoms in sensitive weeds are 
evidenced by marginal yellowing, which is followed by yellowing and browning of the 
entire leaf, usually occurring within 4-7 days after application. Activity is more rapid at 
higher temperatures and under good growing conditions. Weed control under adverse 
conditions such as drought, low temperatures, etc. may be decreased. Rainfall or 
irrigation occurring 1-2 hours after application of Tough 5 EC has little effect on the 
degree of control. 
Mixing Instructions 
IMPORTANT: Follow the correct mixing order on the label or the material may not mix 
properly. Poor mixing may result in crop injury or poor product performance.

r 
-8-
1. Make sure the spray tank is clean before mixing. If it is contaminated with other 
materials, mixing problems and/or clogging may occur, or injury to the crop may 
result. 
2. Fill the spray tank 1/4_112 full with clean water and begin agitation. 
3. Make certain that the agitation system is working properly and creates a rippling 
or rolling action on the liquid surface. Maintain agitation throughout the mixing 
and spraying process. 
4. Add any products packaged in water-soluble film to the tank first. Allow the 
packets to completely dissolve and the contents of the packets to fully and 
uniformly disperse into the mix water. Important: Water-soluble packets must 
always be the first material put Into the spray tank after water. For products 
packaged In water-soluble packaging, do not tank mix with products containing 
boron and do not mix in equipment previously used to apply a product mixture 
containing boron unless the tank and spray equipment have been thoroughly 
cleaned. 
5. While maintaining agitation, continue filling the spray tank. When the tank is 3/4 
full, add desired tank mix partners. Water-dlspersible granules or other dry 
formulations should be added first. Allow material to disperse. Then add Tough 
5 EC followed by other labeled emulsifiable concentrate tank mix partners. 
6. Follow by adding either (a) a nonionic surfactant with a minimum of 80% of the 
constituents effective as a spray adjuvant (e.g., X-77®), at the rate of 1 qt./100 
gals. of spray volume (0.25% volumelvolume) or (b) a petroleum- or vegetable­
based crop oil concentrate containing not less than 12% emulsifier at 1-4 pts.lA 
as specified on the crop oil adjuvant label. The concentration of the crop oil 
concentrate should not exceed 2.5% vol!Jmelvolume. In addition to crop oil 
concentrate or nonionic surfactant, liquid nitrogen fertilizer (28-34% nitrogen­
ammonium form) may also be added at 2-4 qts.lA. Instead of the liquid nitrogen 
fertilizer, spray grade ammonium sulfate may be used at the rate of2-4 IbsJA. 
Liquid nitrogen fertilizers or ammonium sulfate should not be used as a substitute 
for crop oil concentrate or nonionic surfactant in the spray mixture. Do not use 
liquid fertilizer as the spray carrier after crop emergence. 
7. If flowable or liquid formulations appearing on the Tough 5 EC label are desired 
as tank mix partners, add them next while continuing to agitate. When Tough 5 
EC is used alone or in tank mix combinations, either crop oil concentrate or a 
nonionic surfactant should be included, with or without liqUid nitrogen fertilizer or 
ammonium sulfate, as described in item 6 above. Do not use crop oil 
concentrate as the spray adjuvant when using tank mixtures with Banvel®, 
Clarity®, or Marksman®. Use a nonionic surfactant with or without liquid

-9-
nitrogen fertilizer or ammonium sulfate as the additive in tank mixtures containing 
these products. 
8. Complete filling the tank, maintaining sufficient agitation at all times to ensure 
surface action until the spray tank mixture is uniform. 
9. An anti-foaming agent may be added to reduce excessive foaming if needed. 
10. Do not 'eave spray In the spra.y tank without continuous agJtatlon.-Always-.-. 
maintain agitation to avoid separation and buildup of undesirable residues on the 
walls of the spray tank. 
11. Tough 5 EC will remain active in the spray solution for at least 12 hours. 
Therefore, make only sufficient mixture that will be sprayed the day in which it will 
be mixed. 
Application: Tough 5 EC is noncorrosive to spray equipment. Before preparing spray 
mixture, be sure all equipment is clean to prevent uneven applications, clogging of 
spray nozzles, or crop injury. Apply Tough 5 EC with a boom sprayer calibrated to a 
constant speed and constant, uniform delivery. Tough 5 EC should be applied in 
sufficient water (15 gals.!A minimum; 20-30 gals.!A recommended), at a pressure of 30-
40 psi to ensure proper coverage. Thorough coverage of target weeds is required for 
optimum results. Use higher spray volumes when treating dense or tall vegetation. 
large crop and weed canopies can shelter smaller weeds. Directed applications below 
large crop canopies are recommended for optimum coverage of target weeds. 
Adjuvants (nonionic surfactants, crop oil, or liquid fertilizer) may be used with Tough 5 
EC tank mixes where allowed by tank mix partners specified in this label. Refer to 
Directions for Use section for specific adjuvant recommendations for use in com and 
peanut. 
Do not apply this product when wind conditions will allow drift to adjacent susceptible 
vegetation. 
Do not use liquid fertilizer solutions as the spray carrier when applying Tough 5 
EC after crop emergence since crop Injury may occur. 
For optimum control of broad leaf weeds, apply Tough 5 EC to actively growing 
weeds by the 40Ieaf stage. A delay in spraying which permits weeds to grow beyond 
the proper application stage may result in decreased control. If weeds are under stress 
and not actively growing, they will be more difficult to control. Scout fields often to 
determine exact timing for application. If treatments must be made under adverse 
conditions or to larger weeds, use the higher rate allowed in this label. Cultivation may 
be necessary after application if all weeds are not properly controlled or if weeds 
regrow.

r 
-10-
Tough 5 EC and tank mixes with herbicides not prohibiting band application may be 
applied as a band treatment. 
Consult your state and local authorities for possible application restrictions and advice 
when applying Tough 5 EC and tank mixes. 
Tough 5 EC rapidly decomposes in soil and has no residual activity. No crop rotation 
restrictions exist following normal harvest of treated crop. DO NOT plant rotational 
crops other than peanut, field com, seed corn, or popcorn within 30 days of the 
last application of Tough 5 EC. Peanut, field com, seed com, or popcorn may be 
replanted immediately such as in catastrophic crop failure from hail, flood, etc. Multiple 
applications of Tough 5 EC may be made providing that the maximum annual use rate 
is not exceeded. Refer to the Rates and Timings section under com and peanut. 
DO NOT apply this product through any type of irrigation equipment. 
FIELD CORN, SEED CORN-, AND POPCORN-
Prior to Tough 5 EC applications, preemergence herbicides such as Bicep II 
MAGNUM®, Bicep Lite II MAGNUM®, Dual II MAGNUM®, or Dual II MAGNUM + 
AAtrex® should be applied for grass control and will Improve control of several of 
the weeds listed In Tables 1 and 2. Consult their respective labels for directions, 
precautions, and limitations before applying. 
Field com is tolerant to Tough 5 EC at all stages of development. Tough 5 EC may be 
applied preplant bumdown or postemergence to field com, seed com, and popcorn up 
to 68 days before harvest. Use Tough 5 EC in tank mixtures with other products for 
preplant bumdown only if such use is allowed on the tank mix partner label. Timing of 
application must be based on the stage of weed growth for optimum weed control and 
minimal competition to the crop. 
-Not all field com inbred lines or popcorn hybrids have been tested for sensitivity to 
Tough 5 EC, nor does Syngenta have access to all seed company data. Therefore, 
Syngenta recommends that specific inbred lines and popcorn hybrids be thoroughly 
tested for potential sensitivity before treating large acreages. 
Do not graze or otherwise feed treated com grain, forage, or fodder to livestock 
within 68 days of application of Tough 5 EC.

resistant to the sulfonylurea (e.g., ClasslC® and Glean®) and/or Imidazolinone (e.g., 
Scepter® and Pursuit®) family of herbicides. 
For best performance, apply Tough 5 EC when weeds are small (prior to the 4-leaf 
stage) and actively growing. Optimal weed control is obtained when Tough 5 EC is 
used in a weed control program following a broad-spectrum preemergence herbicide 
such as Dual II MAGNUM, Bicep II MAGNUM, Bicep Lite II MAGNUM, or Dual I! 
MAGNUM + Mtrex. 
Special Use Directions for Partial Control of Yellow and Purple Nutsedge: Apply 
24 fl. oz. of Tough 5 EC with 2 pts. of Mtrex 4L (atrazlne) per treated acre when 
sedges are 6-8 inches high for partial control of yellow and purple nutsedge. The 
addition of a crop oil concentrate is recommended for improved activity. Tough 5 EC 
will bum back the top growth of the sedges. Regrowth may occur. Sedges must be 
actively growing without stress for optimum results. Partial control means significant 
activity, but not always at a level generally considered acceptable for commercial weed 
control.

-12-
Rates and Timings 
Tough 5 EC may be applied postemergence up to 68 days before harvest. 
Tough 5 EC at 12-24 fl. oz. per treated acre may be applied to actively growing 
broadleaf weeds at any stage of com growth in all tillage systems (conventional, no 
tillage, or reduced tillage). Split applications of Tough 5 EC may be made, but do not 
exceed a total of 24 fl. oz. per treated acre per year. Consult the Application section of 
this label for best application timing for achieving optimum weed control. 
Tank Mix Treatments In Corn 
Tough 5 EC may be tank mixed with one or more of the following herbicides for control 
of additional broadleaf weeds and/or grasses. Read and follow the label of each tank 
mix product used for precautionary statements, directions for use, rates and 
timings, and other restrictions. Tank mixing Tough 5 EC with other com herbicides 
can offer many benefits, including greater weed control spectrum, different modes of 
action to reduce or delay the development of herbicide resistance by weeds, optimizing 
performance of tank mix partners, etc. Optimization of performance of 
postemergence applications is particularly beneficial when tank mixing with a 
residual herbicide such as atrazlne. Tank mixing of Tough 5 EC and members of the 
sulfonylurea class of herbicides (i.e., Acceni®, Beacon®, Exceed®, or Spirit .... , etc.) 
may cause reduced velvetleaf control (antagonism). 
Adjuvants (nonionic surfactants, crop oil, or liquid fertilizer) may be used with Tough 5 
EC tank mixes where allowed by tank mix partners specified in this label. Do not use 
liquid fertilizer solutions as the spray carrier when applying Tough 5 EC after 
corn emergence. Read and carefully follow aU restrictions and recommendations of 
tank mix partners. Use of tank mix partners is only allowed where permitted in each 
state. 
Tough 5 EC + AAtrex (atrazlne): For additional broadleaf weed control (see Table 2), 
apply 12-24 fl. oz. of Tough 5 EC with 1-2 pts. of AAtrex 4L (atrazine) or the equivalent 
of 900F per treated acre. The addition of a crop oil concentrate Is recommended for 
optimum control. Do not apply this tank mix to corn greater than 12 Inches tall. 
Use the lower rates of Tough 5 EC and AAtrex 4Uatrazine when weeds have fewer 
than 4 leaves. For broad leaf weeds above 4-leaf stage, heavy weed infestation, or use 
under adverse conditions such as drought stress, use the higher rates of Tough 5 EC 
and AAtrex 4Uatrazine.

r 
-13-
To control moderate infestations of escaped grasses following application of a preplant 
incorporated or preemergence grass herbicide, apply 12-24 fl. oz. of Tough 5 EC plus 2-
3 pts. of AAtrex 4Uatrazine or the equivalent of 900F per treated acre. Applications 
should be made before escaped grasses reach the 3-leaf stage (approximately 1.5 
inches tall). The addition of a crop oil concentrate is recommended for optimum control 
of escaped grasses. 
Follow all label restrictions as well as state and local restrictions on atrazine use.

Special Use Directions for Partial Control of Yellow and Purple Nutsedge: Apply 
24-36 fl. oz. of Tough 5 EC when sedges are 6-8 inches high for partial control of yellow 
and purple nutsedge. The addition of a crop oil concentrate is recommended for 
improved activity. Tough 5 EC will burn back the top growth of the sedges. Regrowth 
may occur. Sedges must be actively growing without stress for optimum results. Partial 
control means significant activity, but not always at a level generally considered 
acceptable for commercial weed control. 
Rates and Timings 
Tough 5 EC may be applied to emerged weeds in peanut from cracking to 68 days 
before harvest. 
Tough 5 EC is recommended to be used as part of a sequential and seasonal peanut 
herbicide program. Depending upon the weed spectrum and emergence, it should be 
applied to peanut at cracking or postemergence, following a standard recommended 
preplant, pre plant incorporated, preemergence, or other at-cracking program of such 
herbicides as: Vemam® 7E, Dual MAGNUM1M, Sonalan 1M, and Prowl® 3.3EC. See all 
labels of products used for specific rates and timings. 
Apply Tough 5 EC at 24-36 fl. oz. per treated acre to emerged actively growing target 
weeds in the 2 to 4-leaf stage and up to 3 inches in height. Split applications of Tough 5 
EC may be made, but do not exceed a total of 48 fl. oz. per treated acre per year. 
Consult the Application section of this label for best application timing for achieving 
optimum weed control. 
Tank Mix Treatments in Peanut 
Tough 5 EC may be tank mixed with one or more of the herbicides listed below for 
control of additional broadleaf weeds and/or grasses. Tank mixing allows greater 
flexibility and a broader spectrum of weed control. Read and follow the label of each 
tank mix product used for precautionary statements, directions for use, rates and 
timings, and other restrictions. Suggested tank mixes include: 
Tough 5 EC + 2,4-0B amine: For broad spectrum broadleaf weed control, apply 24-36 
fl. oz. of Tough 5 EC with 0.2-0.25 lb. acid equivalent of 2,4-DB per treated acre. A 
nonionic surfactant or crop oil concentrate may be added to improve weed control. The 
addition of spray additives will increase the hormonal 2,4-DB response in peanut. In 
areas where lambsquarter and pigweed are the primary weed problems, apply 18 fl. oz. 
of Tough 5 EC tank mixed with. 0.2-0.25 lb. acid equivalent of 2,4-DB per treated acre.
