ENVIRONMENTAL HAZARDS 
Carfentrazone-ethyl is very toxic to algae and moderately toxic to fish. DO NOT apply directly to water, to 
areas where surface water is present or to intertidal areas below the high water mark, except as specified 
on this label. DO NOT contaminate water when disposing of equipment wash. 
 
Fish Advisory Statement: 
 
This product may be hazardous to aquatic organisms, particularly in clear, shallow water bodies that are 
adjacent to treated areas. Transport to water by runoff or spray drift of this product in areas where surface 
water is present, or intertidal areas below the mean high water mark, should be avoided. DO NOT 
contaminate water when disposing of equipment wash water or rinsate.
 
 
For ground water: 
Residues of this chemical have properties and characteristics associated with chemicals detected in ground 
water. Residues of this chemical may leach into gr ound water if the chemical is used in areas where soils 
are permeable, particularly where the water table is shallow. 
 
For surface water: 
This product may impact surface water quality due to runoff of rain water. This is especially true for poorly 
draining soils and soils with shallow ground water. This product is classified as having high potential for 
reaching surface water via runoff for several months or more after application. A level, well-maintained 
vegetative buffer strip between areas to which this product is applied and surface water features such as 
ponds, streams, and springs will reduce the potential loading of carfentrazone-ethyl residues from runoff 
water and sediment. Runoff of this product will be reduced by avoiding applications when rainfall is 
forecasted to occur within 48 hours. 
 
Non-target Organism Advisory Statement: 
 
This product is toxic to plants and may adversely impact the forage and habitat of non-target organisms, 
including pollinators, in areas adjacent to the treated site. Protect the forage and habitat of non-target 
organisms by minimizing spray drift.

WEED RESISTANCE MANAGEMENT 
For resistance management, WC-CFZ is a Group 14 herbicide. Any weed population may contain or 
develop plants naturally resistant to WC-CFZ and other Group 14 herbicides. The resistant biotypes may 
dominate the weed population if these herbicides are used repeatedly in the same field. Appropriate 
resistance management strategies should be followed. 
 
To delay herbicide resistance, take one or more of the following steps: 
 
• Rotate the use of WC-CFZ or other Group 14 herbicides within a growing season sequence or among 
growing seasons with different herbicide groups that control the same weeds in a field. 
 
• Use tank mixtures with herbicides from a different group if such use is permitted; where information on 
resistance in target weed species is available, use the less resistance-prone partner at a rate that will 
control the target weed(s) equally as well as the more resistance-prone partner. Consult your local 
extension service or certified crop advisor if you are unsure as to which active ingredient is currently less 
prone to resistance. 
 
• Adopt an integrated weed-management program for herbicide use that includes scouting and uses 
historical information related to herbicide use and crop rotation, and that considers tillage (or other 
mechanical control methods), cultural (e.g., higher crop seeding rates; precision fertilizer application

4
method and timing to favor the crop and not the weeds), biological (weed-competitive crops or varieties) 
and other management practices. 
 
• Scout before and after herbicide application to monitor weed populations for early signs of resistance 
development. Indicators of possible herbicide resistance include: (1) failure to control a weed species 
normally controlled by the herbicide at the dose applied, especially if control is achieved on adjacent 
weeds; (2) a spreading patch of non-controlled plants of a particular weed species; (3) surviving plants 
mixed with controlled individuals of the same species. If resistance is suspected, prevent weed seed 
production in the affected area by an alternative herbicide from a different group or by a mechanical 
method such as hoeing or tillage. Prevent movement of resistant weed seeds to other fields by cleaning 
harvesting and tillage equipment when moving between fields and planting clean seed. 
 
• If a weed pest population continues to progress after treatment with this product, discontinue use of this 
product, and switch to another management strategy or herbicide with a different mode of action, if 
available. 
 
• Contact your local extension specialist or certified crop advisors for additional pesticide resistance-
management and/or integrated weed-management recommendations for specific crops and weed 
biotypes. 
 
 
• For further information or to report suspected resistance, contact your FMC representative. 
 
PRODUCT INFORMATION 
WC-CFZ is a water dispersible granule formulation. WC-CFZ can be applied with water, liquid fertilizer or 
mixtures of water and liquid fertilizer and adjuvants and applied to labeled crops and non-crop areas for 
selective postemergence control of broadleaf weeds, for sucker control, for burndown prior to planting, as a 
harvest aid and to defoliate/desiccate labeled crops. 
 
Weed control is optimized when the product is applied to actively growing weeds. WC-CFZ is a contact 
herbicide. Within a few hours following application, the foliage of susceptible weeds show signs of 
desiccation. 
 
Extremes in environmental conditions e.g. temperature, moisture, soil conditions, and cultural practices 
may affect the activity of WC-CFZ. Herbicide symptoms may be accelerated under moist conditions. Weed 
control may be reduced when weeds are hardened off by drought and become less susceptible to WC-
CFZ. 
 
WC-CFZ is rapidly absorbed through the foliage of plants. To avoid significant crop response, DO NOT 
make applications within 6 to 8 hours of either rain or irrigation or when heavy dew is present on the crop. 
Environmental conditions and certain spray tank additives may increase herbicidal symptoms on the crop. 
 
TANK MIXTURES 
WC-CFZ may be tank-mixed with other registered herbicides for controlling broader spectrum weeds. 
Refer to this and other product’s labels for mixing instructions, precautions, and restrictions. Follow the 
most restrictive instructions for each tank mix partner. When preparing a new tank mix conduct an 
appropriate compatibility test by mixing proportional amounts of all spray ingredients in a test vessel (jar) 
prior to tank mixing with other products. Shake the mixture vigorously and allow it to stand for five to ten 
minutes. DO NOT apply if rapid precipitation of the ingredients and failure to re-suspend when shaken as 
this indicates that the mixture is incompatible. 
 
It is the pesticide user’s responsibility to ensure that all products are registered for the intended use. Read 
and follow the applicable restrictions and limitations and directions for use on all product labels involved in 
tank mixing. Users must follow the most restrictive directions for use and precautionary statements of each 
product in the tank mixture. 
 
When tank mixing with fertilizer solutions, be sure to prepare a premixture of WC-CFZ and clean 
water.

5
ADJUVANT USE REQUIREMENTS 
The use of a quality spray adjuvant is required for optimum performance. Refer to the individual crop 
sections of this label for specific adjuvant type and use rates. 
 
ON-FARM TESTING 
Not all varieties or cultivars of labeled crops have been fully evaluated under all environmental and soil 
conditions. Consult with your local seed company for additional information. It may also be beneficial to 
conduct small on-farm trials under actual conditions with specific varieties or cultivars before treating large 
acreage. 
 
MIXING INFORMATION 
Mixing and Loading Instructions 
Fill the spray tank 3/4 full with clean water. Make sure the agitation system is operating while adding 
products. Prepare a slurry of WC-CFZ in a clean container using clean water. Slowly add the WC-
CFZ/water slurry. Carefully rinse the slurry container adding the rinsate to the spray tank. Complete filling 
the spray tank to the desired level. Sufficient spray tank agitation will ensure uniform spray mixture during 
application and must continue until the spray tank has been emptied. Follow your local extension 
guidelines for mixing order of products. In spray tank add dry products first, agitate, water emulsions or 
water soluble liquids next, emulsifiable concentrates, and then adjuvants last. Ensure the compatibility of 
other products and/or liquid fertilizers with WC-CFZ before mixing them together in the spray tank. 
 
Mixing Precautions 
Avoid the overnight storage of WC-CFZ spray mixtures. If spray solution is stored overnight or longer, 
thoroughly agitate spray mixture before applying the solution. Premixing WC-CFZ spray solutions in nurse 
tanks is not advised. Maintain continuous and adequate spray solution agitation until all the spray solution 
has been used. Buffer spray solution to maintain the pH range of 5 to 8. 
 
SPRAY EQUIPMENT CLEAN-OUT 
Many new pesticides are very active at low rates, especially to sensitive crops. Residues left in 
mixing equipment, spray tanks, hoses, spray booms and nozzles can cause crop effects if they are not 
properly cleaned. As soon as possible after spraying WC-CFZ and before using the sprayer equipment for 
any other applications, the sprayer equipment must be thoroughly cleaned using the following procedure. 
In addition, users must take appropriate steps to ensure proper equipment clean-out for any other products 
mixed with WC-CFZ as required on the other product labels. More complete cleaning can be achieved if 
the spray system is cleaned immediately following the application. 
 
1. Drain sprayer tank, hoses, spray boom and spray nozzles. Use a high-pressure detergent wash to 
remove physical sediment and residues from the inside of the sprayer tank and thoroughly rinse. Then, 
thoroughly flush sprayer hoses, spray boom and spray nozzles with a clean water rinse. Remove and clean 
spray tips and all filters and screens (tank, spray hose and spray tips) separately in the ammonia solution 
of Step 2. 
 
2. Next, prepare a sprayer cleaning solution by adding three gallons of ammonia (containing at least 3% 
active) per 100 gallons of clean water. Prepare sufficient cleaning solution to allow the operation of the 
spray system for a minimum of 15 minutes to thoroughly flush hoses, spray boom and spray nozzles. 
 
3. Convenient and thorough cleaning of the sprayer can be achieved if the ammonia solution or fresh water 
is left in the spray tank, hoses, spray booms and spray nozzles overnight or during storage. 
 
4. Before using the sprayer, completely drain the sprayer system. Rinse the tank with clean water and flush 
through the hoses, spray boom, and spray nozzles with clean water. 
 
5. Properly dispose of all cleaning solution and rinsate in accordance with Federal, State, and local 
regulations and guidelines. 
 
DO NOT apply sprayer cleaning solutions or rinsate to sensitive crops.

6
Avoid storing the sprayer overnight or for any extended period of time with WC-CFZ spray solution 
remaining in the tank, spray lines, spray boom plumbing, spray nozzles or strainers. 
 
If the sprayer has been stored or idle, purge the spray boom and nozzles with clean water before beginning 
any application. 
 
If small quantities of WC-CFZ remain in inadequately cleaned mixing, loading and/or spray equipment, they 
may be released during subsequent applications potentially causing effects to certain crops and other 
vegetation. FMC accepts no liability for any effects due to inadequately cleaned equipment. 
 
APPLICATION METHODS 
 
GROUND APPLICATION 
Broadcast Application 
Use a broadcast boom sprayer equipped with the appropriate nozzles, spray tips and screens and adjusted 
to provide optimum spray distribution and coverage at the appropriate operating pressures. Use nozzles 
that produce minimal amounts of fine spray droplets. DO NOT exceed 30 psi spray pressure unless 
permitted by the manufacturer of drift reducing nozzles. Apply a minimum of 10 gallons of finished spray 
per acre. Use higher spray volumes when there is a dense weed population or crop canopy. Adjust 
sprayers to position spray tips no lower than 12-18 inches above the crop or weed canopy depending on 
the nozzle specification. Operate the sprayer to avoid the application of high herbicide rates directly over 
the rows or into the whorl of treated crop plants. 
 
Post-Directed Application 
Post-directed applications may be utilized when labeled crops have reached minimum growth stages 
where sprays may be directed to the target weeds, but is not deposited on the green stem, foliage, blooms 
or fruit of the crop. DO NOT apply when conditions favor drift or when wind speed is above 10 miles per 
hour. 
Use drop nozzles or other spray equipment capable of directing the spray to target weeds and away from 
sensitive plant parts. Apply when labeled crops have reached minimum growth stages described in 
specific crop sections of this label and when spray will not be deposited on green stems, foliage, blossoms 
or fruit. 
 
Hooded/Shielded Sprayer Application 
To apply WC-CFZ using a hooded or shielded sprayer, refer to the Hooded/Shielded Sprayer Section for 
specific adjustment and operation instructions. For additional information, refer to the individual crop 
sections of this label. 
 
Hand-Held or High Volume Gun Application 
WC-CFZ may be applied with hand operated sprayers such as backpack sprayers, compression sprayers, 
knapsack sprayers, or high volume orchard gun sprayers. Directed applications may be utilized when 
labeled crops have reached minimum growth stages where sprays may be directed to the target weeds, 
but is not deposited on the green stem, foliage, blooms or fruit of the crop. 
 
AERIAL APPLICATION 
Use nozzle types and arrangements that will provide optimum coverage while producing a minimal amount 
of fine droplets. Apply at a minimum of 3 gallons of finished spray per acre. Spray volumes greater than 3 
gallons per acre may be needed for harvest aid and defoliation treatments, or for dense weed populations 
or with dense crop canopies. 
 
For Aerial Application in California: 
Refer to individual crop sections to see if WC-CFZ application is permitted by air 
For applications near desirable perennial vegetation or crops before blossom and after total leaf drop, 
and/or near other desirable or annual crops: 
DO NOT apply within 100 feet of all desirable vegetation or crops but if wind up to 10 miles per hour is 
blowing toward desirable vegetation or crops, DO NOT apply within 500 feet of the desirable vegetation or 
crops.

7
DO NOT apply when winds are in excess of 10 mph or when inversion conditions exist. 
 
 
SPRAY DRIFT MANAGEMENT ADVISORIES 
 
THE APPLICATOR IS RESPONSIBLE FOR AVOIDING OFF-SITE SPRAY DRIFT. 
BE AWARE OF NEARBY NON-TARGET SITES AND ENVIRONMENTAL CONDITIONS. 
IMPORTANCE OF DROPLET SIZE 
An effective way to reduce spray drift is to apply large droplets. Use the largest droplets that provide target 
pest control. While applying larger droplets will reduce spray drift, the potential for drift will be greater if 
applications are made improperly or under unfavorable environmental conditions. 
Controlling Droplet Size – Ground Boom 
• Volume - Increasing the spray volume so that larger droplets are produced will reduce spray drift. Use 
the highest practical spray volume for the application. If a greater spray volume is needed, consider using 
a nozzle with a higher flow rate. 
• Pressure - Use the lowest spray pressure directed for the nozzle to produce the target spray volume 
and droplet size. 
• Spray Nozzle - Use a spray nozzle that is designed for the intended application. Consider using nozzles 
designed to reduce drift. 
Controlling Droplet Size – Aircraft 
Adjust Nozzles - Follow nozzle manufacturers recommendations for setting up nozzles. Generally, to 
reduce fine droplets, nozzles should be oriented parallel with the airflow in flight. 
 
BOOM HEIGHT – Ground Boom 
Use the lowest boom height that is compatible with the spray nozzles that will provide uniform coverage. 
For ground equipment, the boom should remain level with the crop and have minimal bounce. 
 
MANDATORY SPRAY DRIFT 
Ground Boom Applications: 
x Apply with the nozzle height recommended by the manufacturer, but no more than 3 feet above the 
ground or crop canopy. 
x For applications prior to the emergence of crops and target weeds, applicators are required to use a 
Coarse or coarser droplet size (ASABE S572.1). 
x For all other applications, applicators are required to use a Medium or coarser droplet size (ASABE 
S572.1). 
x DO NOT apply when wind speeds exceed 10 miles per hour at the application site. 
x DO NOT apply during temperature inversions. 
Aerial Applications: 
x DO NOT release spray at a height greater than 10 feet above the vegetative canopy, unless a 
greater application height is necessary for pilot safety. 
x For applications prior to the emergence of crops and target weeds, applicators are required to use a 
Coarse or coarser droplet size (ASABE S572.1). 
x For all other applications, applicators are required to use a Medium or coarser droplet size (ASABE 
S572.1). 
x The boom length must not exceed 65% of the wingspan for airplanes or 75% of the rotor blade 
diameter for helicopters. 
x Applicators must use one-half swath displace ment upwind at the downwind edge of the field. 
x Nozzles must be oriented so the spray is directed toward the back of the aircraft. 
x DO NOT apply when wind speeds exceed 10 miles per hour at the application site. 
x DO NOT apply during temperature inversions.

RELEASE HEIGHT - Aircraft 
Higher release heights increase the potential for spray drift. When applying aerially to crops, do not 
release spray at a height greater than 10 ft above the crop canopy, unless a greater application height is 
necessary for pilot safety.
 
SHIELDED OR HOODED SPRAYERS 
Shielding the boom or individual nozzles can reduce spray drift. Consider using shielded sprayers. Verify 
that the shields are not interfering with the uniform deposition of the spray on the target area. 
 
TEMPERATURE AND HUMIDITY 
When making applications in hot and dry conditions, use larger droplets to reduce effects of evaporation. 
 
TEMPERATURE INVERSIONS 
Drift potential is high during a temperature inversion. Temperature inversions are characterized by 
increasing temperature with altitude and are common on nights with limited cloud cover and light to no 
wind. The presence of an inversion can be indicated by ground fog or by the movement of smoke from a 
ground source or an aircraft smoke generator. Smoke that layers and moves laterally in a concentrated 
cloud (under low wind conditions) indicates an inversi on, while smoke that moves upward and rapidly 
dissipates indicates good vertical air mixing. Avoid applications during temperature inversions. 
 
WIND 
Drift potential generally increases with wind speed. AVOID APPLICATIONS DURING GUSTY WIND 
CONDITIONS. Applicators need to be familiar with local wind patterns and terrain that could affect spray 
drift. 
 
HANDHELD TECHNOLOGY APPLICATIONS: 
Take precautions to minimize spray drift 
 
DRIFT CONTROL ADDITIVES 
Using product compatible drift control additives can reduce drift potential. When a drift control additive is 
used, read and carefully observe cautionary statements and all other information on the additive’s label. 
If using an additive that increases viscosity, ensure that the nozzles and other application equipment will 
function properly with a viscous spray solution. 
Preferred drift control additives have been certified by the Council of Producers & Distributors of 
Agrotechnology (CPDA). 
 
CROP ROTATIONAL RESTRICTIONS 
Following an application of WC-CFZ, a treated field may be rotated to a registered crop at any time, 
subject to specific crop restrictions that may be found in the individual crop sections. Sugarbeets, leafy 
vegetables (except brassica) Crop Group 4, and bulb vegetables (Crop Group 3-07) may be planted after 
4 months. All other crops may be planted after 12 months.

PREPLANT BURNDOWN AND FALLOW APPLICATIONS 
Apply WC-CFZ alone or with other herbicides or liquid fertilizers as a burn-down treatment to control or 
suppress weeds. WC-CFZ is effective as a burndown treatment for crops prior to new plantings. Apply 
WC-CFZ at the specified rates in the table below for each crop. For optimum performance, make 
applications to actively growing weeds up to 4 inches high or rosettes less than 3 inches across. 
Coverage is essential for good control. Optimum broad-spectrum control of annual and perennial 
weeds requires a tank mix with a labeled burndown herbicides e.g. glyphosate, glufosinate, paraquat, 
2,4-D, or dicamba.

For optimum results, treat weeds when small. Make applications in spray volumes sufficient to 
provide complete coverage of foliage. Some temporary leaf speckling and necrosis ocurring on 
green alfalfa or clover tissue between cutting applications, will be rapidly outgrown under good 
growing conditions. Adjuvant selection and high moisture environmental conditions will enhance 
this effect. For adjuvant selection, consult the Adjuvant section of the label. Coverage is essential for 
satisfactory performance. DO NOT irrigate just prior to or just after application. Weed control under 
dry and hot conditions will be improved with COC or similar products.

Postemergence Weed Control Treatment 
Apply WC-CFZ alone or as a tank mixture with other herbicides to emerged and actively growing 
weeds. Apply to corn in all tillage systems from prior to planting up to 14-leaf collar growth stage. Apply 
broadcast from emergence to V8 stage. Applications to corn greater than V8 stage, utilize drop nozzles 
aligned between the rows with directed application to reduce contact with the corn foliage and improve 
contact with the weeds. (See Directed Applications section below). For optimum performance, make 
application to actively growing weeds up to 4 inches high and rosettes less than 3 inches across. Coverage 
is essential for good control. 
 
Adjuvant Requirements: 
Use a non-ionic surfactant (NIS) at 0.25% v/v (2 pints per 100 gallons of spray solution). Under dry 
conditions, the use of a crop oil concentrate (COC) at 1.0% v/v may improve weed control. The use of crop 
oil concentrate can increase leaf speckling and crop response on treated corn leaves. 
For specific mixing instructions, refer to the Mixing and Loading Instructions under the PRODUCT 
INFORMATION section. 
Refer to the other product’s label for restrictions on tank mixing, and observe all label precautions, 
instructions, and rotational cropping restrictions. Adjust sprayers to position spray tips no lower than 18 
inches above the crop. Operate the sprayer to avoid the application of high herbicide rates directly over the 
rows and/or into the whorl of the corn plant. Overlaps and slower ground speeds (caused by continuing to 
spray while starting, stopping or turning) may result in higher application rates and possible crop response. 
 
Broadcast Applications: (Emergence to V8 stage) 
Use WC-CFZ at 0.3 to 0.6 oz/A (0.008 to 0.016 lb ai/A). Use higher rates when weeds are under stress or 
are larger. 
 
Tank Mix (See ‘Tank Mixtures’ for additional tank mixture requirements) 
WC-CFZ may be tankmixed with other corn herbicides to control weeds not listed on this label. Read and 
follow all manufacturers’ label directions for the companion herbicides. When tank mixing WC-CFZ with

17 
other labeled corn herbicides, use adjuvants as directed by the tank mix partner’s label. These may include 
nonionic surfactant, crop oil concentrate, 28% nitrogen, ammonium sulfate or combinations of these.

For the control of additional or certain larger weeds up to 6 inches tall, Atrazine may be added to the tank 
mixtures of WC-CFZ plus dicamba or WC-CFZ plus 2,4-D (amine). 
 
Add 2,4-D (amine) or dicamba to the tank mix at labeled rates. Higher rates of atrazine and dicamba 
herbicides are allowed, but DO NOT exceed the specific label use rates allowed by these labels. Add a 
0.25% v/v nonionic surfactant (2 pints per 100 gallons) to the tank mixture. Under very dry soil moisture 
conditions, the use of crop oil concentrate at 1% v/v (1 gallon per 100 gallon spray solution) may improve 
weed control. The use of crop oil concentrate may increase leaf speckling. Refer to the Tank Mixture 
section for information on potential leaf injury. 
 
For control of the following weeds up to 6 inches in height, or as specified, add dicamba at labeled 
rates to WC-CFZ tank mixes with atrazine or to WC-CFZ tank mixes with other products that allow 
the use of dicamba on their labels:

Directed Spray Applications (V8 to V14 stage): 
Apply WC-CFZ with drop nozzles between the rows to the target weeds and away from the whorl of the corn 
plant. Use directed spray applications when corn is V8 to V14 stage. Apply WC-CFZ up to 1.24 oz/A (0.031 
lb ai/A). Rates above 0.3 oz/A (0.008 lb ai/A) will aid in control of larger weeds as listed under Weed Control 
(Table 1). Be aware that weeds growing in and under the dense canopies may not receive adequate spray 
coverage and may require the use of higher spray volumes for acceptable control. Use appropriate rates of 
adjuvants such as non-ionic surfactant (NIS), crop oil concentrate (COC), or methylated seed oil (MSO). 
 
Harvest Aid (Hard Dough to 3 days before harvest): 
Apply 0.6 to 1.24 oz/A of WC-CFZ (0.016 – 0.031lb ai/A), but not to exceed maximum labeled rates. If 
treatments of WC-CFZ have been made to the crop earlier, that volume must be considered in determining 
the maximum use rate as a harvest aid treatment. 
Applications shall be made in spray volumes sufficient to provide complete coverage of foliage. Use a 
minimum of 15 gallons of finished spray per acre for ground application and 5 gallons per acre for aerial 
application. A methylated seed oil (MSO) or crop oil concentrate (COC) is required. Use methylated seed oil, 
or crop oil concentrate (COC) (petroleum or seed oil) at 1 to 2% v/v (1 to 2 gallons per 100 gallons of spray 
solution). A high quality sprayable liquid nitrogen fertilizer at 2 to 4 % v/v (2 to 4 gallons per 100 gallons 
spray solution) or ammonium sulfate (AMS) at the rate of 2 to 4 pounds per acre in addition to the 
methylated seed oil or crop oil is allowed. 
 
Seed Corn Production: 
For seed production fields, apply WC-CFZ using drop nozzles or other equipment to make a directed spray 
treatment. Avoid directing spray solution into the whorl. 
 
Seed corn inbred lines have generally shown good resistance to WC-CFZ. However, all inbred lines have 
not been tested. Broadcast applications may result in spray being concentrated into the whorl of the plant 
that will increase leaf response. To minimize application into the whorl of the plants, drop nozzles or other 
type directed sprayers must be used to direct the spray to the targeted weeds. 
 
Sweet Corn Precaution: 
When applying WC-CFZ to sweet corn; broadcast applications may result in spray being concentrated into 
the whorl of the plant that will increase leaf response. To minimize application into the whorl of the plants, 
drop nozzles or other type directed sprayers must be used to direct the spray to the targeted weeds. 
 
Use only NIS as the spray adjuvant in sweet corn applications. 
 
Application Precautions: 
Leaf speckling can occur when WC-CFZ is used with certain crop protection products and adjuvants. Refer 
to the Tank Mixtures and Adjuvants requirements sections under PRODUCT INFORMATION. Bromoxynil 
mixtures and bentazon mixtures may cause significant crop response when in contact with crop foliage. 
 
Crop Response 
The application of WC-CFZ to corn may result in temporary crop response such as speckling or necrosis of 
the leaves. Grain yields will not be affected. DO NOT make applications when air temperatures are

19 
abnormally cool or humidity is high or if the corn foliage is wet from dew, rainfall or irrigation. Users must be 
aware of these inherent risks and accept these risks prior to application of WC-CFZ. 
 
For additional information regarding potential crop response, refer to the PRODUCT INFORMATION section 
of the WC-CFZ label.

must be made with directed sprayers, hooded, or shielded sprayers to prevent contact of spray solution with 
the cotton plant. DO NOT allow spray solution to contact cotton foliage, green stem tissue, or blooms. 
Directed spray equipment must position nozzles a minimum 3 to 4 inches above the soil, with nozzles 
directed beneath the crop canopy. WC-CFZ or WC-CFZ tank mix applications shall be made to cotton that is 
a minimum of 6 inches in height. Applications to cotton at 5 to 6 nodes or less must be made with hooded or 
shielded sprayer equipment to completely avoid contact with cotton plants. Apply lay-by applications of WC-
CFZ or WC-CFZ tank mixtures at later growth stages of cotton when cotton plants have achieved a height of

20 
12 inches or more with sufficient bark development and height differential between crop bottom leaves and 
the soil. Spray solution shall be directed at the base of cotton plants for minimal contact with green stem 
tissue or foliage while maintaining maximum contact with broadleaf weeds that are at appropriate treatment 
size. 
 
For optimum performance, make application to actively growing weeds up to 4 inches tall and rosettes less 
than 3 inches across. Coverage is essential for good control. 
 
Adjuvant Requirement For All Cotton Applications Except Managed Maturity and Defoliation/Harvest 
Aid 
A nonionic surfactant (NIS), methylated seed oil (MSO) or crop oil concentrate (COC) is required. Use a 
nonionic surfactant (NIS) at 0.25% v/v (2 pints per 100 gallons of spray solution) having at least 80% active 
ingredient, or a methylated seed oil, or crop oil concentrate (COC) (petroleum or seed oil) at 1 to 2 v/v (1 to 
2 gallons per 100 gallons of spray solution). A high quality sprayable liquid nitrogen fertilizer at 2 to 4 % v/v 
(2 to 4 gallons per 100 gallons spray solution) or ammonium sulfate (AMS) at the rate of 2 to 4 pounds per 
acre in addition to the nonionic surfactant methylated seed oil or crop oil is allowed.

For control of additional broadleaf weeds and grasses, WC-CFZ may be tank mixed with other herbicides 
registered for cotton post-directed and/or lay-by applications. Refer to the other product’s label for 
restrictions on tank mixing, and observe all label precautions, instructions and rotational cropping 
restrictions. 
 
Managed Maturity Application for Cotton 
Apply WC-CFZ as an aid to remove undesirable top growth and reduce unproductive terminal growth. Use 
alone or as a tank mixture with other cotton insecticides and herbicides. Read all product labels and follow 
all directions and precautions when tank mixing with this product. 
 
 
Timing 
Apply WC-CFZ when cotton is actively growing and the plants have 1% to 25% open bolls; with applications 
at 20% open bolls being optimum. When using the Cotman monitoring program, apply WC-CFZat NAWF5, 
plus 450 – 650 heat units. Avoid Managed Maturity treatments to fields, or areas of fields, that are stressed. 
 
WC-CFZ Use Rates – Manage Maturity 
Apply WC-CFZ as a broadcast spray at 0.15 oz/A (0.004 lb ai/A) to 0.3 Oz/A(0.008 lb ai/A), targeting 0.22 
oz/A (0.006 lb ai/A) in spray volume adequate to obtain upper canopy coverage of the plant foliage. In 
situations of extremely lush growth, apply up to 0.3 oz/A (0.008 lb ai/A). Make applications using a minimum

21 
of 10 gallons of finished spray per acre for ground application and a minimum of 5 gallons per acre by air. 
Good upper canopy coverage is essential for optimum performance. 
 
Use a quality crop oil concentrate (COC) at the specified rate of 1% v/v. 
 
Defoliation / Harvest Aid Application 
Apply WC-CFZ as a harvest aid to defoliate and desiccate cotton and troublesome weeds that may be 
present at harvest. Apply WC-CFZ alone or as a tank mixture with other cotton harvest aids. Use a quality 
spray adjuvant e.g. nonionic surfactant (NIS) or crop oil concentrate (COC) at the labeled rates. NIS is the 
specified adjuvant during warmer periods with COC being the better choice for applications during cooler 
periods. Make application when 60 to 70 percent of the bolls are open, or according to the State Agricultural 
Extension Service guidelines in the use area. 
 
Apply up to 1.0 oz/A of WC-CFZ (0.025 lb ai/A) in spray volume sufficient to provide complete coverage of 
cotton foliage. Use a minimum of 10 gallons of finished spray per acre for ground application and 5 gallons 
per acre for aerial application. Coverage is essential for good defoliation. Repeat application if 
necessary to remove remaining foliage or control regrowth. DO NOT apply more than 2.0 oz/A (0.05 lb ai/A) 
per acre total as a harvest aid. Dense cotton canopy, large plant size, and environmental conditions not 
conducive to complete plant coverage may reduce initial application performance and increase the need for 
a second application. 
 
Apply WC-CFZ alone, or as a tank mix, or as a sequential application alone or tank mixed with other 
registered cotton harvest aid products. 
 
Refer to the other product’s label for restrictions on tankmixing, and observe all label precautions, 
instructions and rotational cropping restrictions.

Harvest Aid 2.0. – 3.6 
(0.05 – 0.09) 
Preemergence Application 
Apply to potatoes and sweet potatoes after hilling for the control of emerged weeds (see Table 1). A 
minimum of 2 inches of soil must cover the vegetative portion of the potato plant at the time of the WC-CFZ 
application. Application with less than 2 inches of soil covering the vegetative portion of the potato or sweet 
potato may result in crop injury. 
 
Harvest Aid Desiccation Application 
Apply WC-CFZ foliar to potatoes in the later stages of senescence for desiccation of potato foliage and 
vines. WC-CFZ will also desiccate late season susceptible broadleaf weeds to aid in tuber harvest. 
Adequate desiccation is achieved within 14 days after the initial treatment is applied. If the potato crop is in 
the active vegetative growth stage when desiccation is initiated, two applications may be required to provide 
desiccation of leaf and stem tissue. Dense potato canopy, large plant size and environmental conditions not 
conducive to product absorption or activity will reduce initial application efficacy and increase the need for a 
second application. If a second application is necessary, apply at 7 to 14 days after the first application. 
Thorough coverage of the potato plant to be desiccated is essential. Use a sufficient volume of water 
to obtain thorough coverage of the potato leaves and vines. 
 
Ground Application 
Apply WC-CFZ in at least 20 gallons of water per acre. Vary the spray volume and spray pressure as 
indicated by the density of the potato canopy and vines to assure thorough spray coverage. Increase the 
spray volume and pressure if the potato canopy is dense or under cool, cloudy or dry conditions. Increased 
spray volumes will enhance performance. 
 
Aerial Application 
Apply WC-CFZ with aerial equipment using 5 to 10 gallons of water per acre, using higher volumes when 
potato canopies and vines are dense. Adjust the nozzles to provide a uniform pattern and a droplet size of 
350 to 450 microns.

surfactant mixture is required. Use a nonionic surfactant (NIS) at 0.25% v/v (2 pints per 100 gallons of 
spray solution) having at least 80% active ingredient, or a methylated seed oil, or crop oil concentrate (COC) 
(petroleum or seed oil) at 1 to 2 v/v (1 to 2 gallons per 100 gallons of spray solution. The use of a high 
quality sprayable liquid nitrogen fertilizer at 2 to 4 % v/v (2 to 4 gallons per 100 gallons spray solution) or 
ammonium sulfate (AMS) at the rate of 2 to 4 pounds per acre in addition to the nonionic surfactant 
methylated seed oil or crop oil is allowed. 
Increase adjuvant rates as spray volumes exceed 20 gallons per acre. 
 
Tank Mixtures 
Apply WC-CFZ as a tank mix or as a sequential application with other potato desiccants. Refer to the other 
product’s label for restrictions on tank mixing, and observe all label precautions, instructions and rotational 
cropping restrictions. When used in combination with other labeled herbicides, rates can be reduced to 1.2 – 
3.6 oz/A (0.03 – 0.09 lb ai/A).

Apply WC-CFZ to the row middles of the following emerged crops using hooded or shielded sprayers to control 
labeled weeds between the rows of the below listed emerged crops. This treatment is for crops grown in rows, and 
includes crops grown in rows where mulch or plastic barriers are used as a weed control tool in the drill or plant 
line. 
 
Hooded or shielded sprayers must be designed, adjusted and operated in such a manner to totally enclose 
the spray pattern and to prevent any spray deposition to green stem tissue, foliage, blooms or fruit of the 
crop. 
 
Sprayers shall not be operated at more than five (5) miles per hour in order to minimize vertical movement of the 
sprayer during application, including the bouncing or raising of the equipment. Use extreme care in applying to 
fields where the soil surface is uneven, has deep furrows, drains or other contours that would disturb the 
adjustment and positioning of the spray equipment and/or the spray pattern. Applications must not be made when 
wind conditions may disturb the spray patterns and result in spray deposition to sensitive plants or plant parts. 
 
For optimum performance, make application to actively growing weeds up to 4 inches tall and rosettes less than 3 
inches across. Coverage is essential for good control. 
 
Precaution: 
Crop injury will occur when spray is allowed to come in contact with the green stem tissue, leaves, blooms 
or fruit of the crop.

AGRICULTURE FARM AND FARMSTEAD USE – NON-CROP 
Timing and Method of Application 
WC-CFZ may be used for broadleaf weed control on farms and farmsteads in areas outside of crop growing areas. 
See Weed Control (Table 1) to determine the proper rate for areas such as grass waterways, field edges, terraces, 
equipment storage areas, shelter belts, fence lines, farm buildings, dry ditch, canal banks etc. WC-CFZ is a contact 
herbicide and coverage is essential for weed control. WC-CFZ will control emerged weeds only. Weeds that 
germinate after application will require repeat treatments. 
Precautions 
Extreme caution must be used to avoid contact with desirable vegetation. DO NOT spray or allow spray mist of 
WC-CFZ to come in contact with green stem tissue, foliage, blooms or desirable fruit. 
 
BOOM EQUIPMENT 
Apply WC-CFZ at up to 1.24 oz/A (0.031 lb ai/A). 
 
Adjuvant Requirements for boom equipment 
A nonionic surfactant, crop oil concentrate or methylated seed oil is required. Use a nonionic surfactant (NIS) at 
0.25% v/v (2 pints per 100 gallons of spray solution) having at least 80% active ingredient or a petroleum or oil 
seed based crop oil concentrate (COC) at 1.5 to 2 % v/v (1.5 to 2.0 gallons per 100 gallons of spray solution) or a 
methylated seed oil (MSO). A high quality sprayable liquid nitrogen fertilizer at 2 to 4 % v/v (2 to 4 gallons per 100 
gallons) or ammonium sulfate at 2 to 4 pounds per acre in addition to the selected NIS, MSO or COC is allowed. 
 
Tank Mixes for boom equipment 
WC-CFZ may be mixed with other labeled herbicides for this method of application in non-crop areas for broader 
spectrum weed control. 
See Mixing and Loading Instructions for specific mixing instructions. Refer to this and the tank mix partner labels for 
mixing instructions, precautions, and restrictions. Follow the most restrictive instructions for each tank-mix partner. 
 
SPOT TREATMENTS (Applications with hand operated sprayer such as backpack sprayers, compression 
sprayers, knapsack sprayers.) 
Mix the amount of WC-CFZ for the desired percent spray solution from the table below. These mixtures are based 
on 1 gallon of solution evenly covering 1000 square feet. Make applications on a spray-to-wet basis. Ensure spray 
coverage is uniform and complete. DO NOT spray to runoff. See Table 1 for weeds controlled at specific

44 
concentrations. Use lower concentrations for small seedling weeds at the 2-3 leaf stage. Higher concentrations are 
needed for larger weeds up to the 6-leaf stage. Applications beyond the 6-leaf stage may result in only partial 
control. WC-CFZ may be mixed with other labeled herbicides e.g. glyphosate, glufosinate, and paraquat for broader 
spectrum weed control.

Adjuvant Requirements for spot treatments 
A nonionic surfactant (NIS), methylated seed oil (MSO) or crop oil concentrate (COC) is required. Use a nonionic 
surfactant (NIS) at 0.25% v/v having at least 80% active ingredient, or a methylated seed oil (MSO), or crop oil 
concentrate (COC) (petroleum or seed oil) at 1 to 2% v/v. A high quality sprayable liquid nitrogen fertilizer at 2 to 4 
% v/v or ammonium sulfate (AMS) at the rate of .75 to 1.5 ounces per gallon in addition to the nonionic surfactant 
methylated seed oil or crop oil is allowed.
