WEED RESISTANCE MANAGEMENT 
WC-SLZ herbicide which contains the active ingredient sulfentrazone is a group 14 herbicide based on the mode of action classification 
system of the Weed Science Society of America. 
Proactively implementing diversified weed control strategies to minimize selection for weed populations resistant to one or more 
herbicides is a best practice. A diversified weed management program may include the use of multiple herbicides with different sites 
of action and overlapping weed spectrum with or without tillage operations and/or other cultural practices. Research has demonstrated 
that using the labeled rate and directions for use is important to delay the selection for resistance. 
The continued effectiveness of this product depends on the successful implementation of a weed resistance management program. 
To aid in the prevention of developing weeds resistant to this product, users should: 
• Scout fields before application for weeds for identification of species and sizes. 
• Start with a clean field, using either a burndown herbicide application or tillage. 
• Control weeds early when they are relatively small (less than 4 inches). 
• Apply full rates of WC-SLZ herbicide for the most difficult to control weed in the field at the specified time (correct weed 
size) to minimize weed escapes. 
• Scout fields after application to detect any poor performance or likely resistance in weeds. 
• Control weed escapes before they reproduce by seed or proliferate vegetatively. 
• Report any incidence of non-performance of this product against a particular weed to your local retailer or county 
extension agent. 
• Contact your crop advisor or extension agent to find out if suspected resistant weeds to this MOA have been found in your 
region. If resistant biotypes of target weeds have been reported, use the application rates of this product specified for your 
local conditions. Tank mix products so that there are multiple effective sites of actions for each target weed. 
• If resistance is suspected, treat weed escapes with an herbicide having a site of action other than 14 and/or use 
nonchemical methods to remove escapes, as practical, with the goal of preventing further seed production. 
• Suspected herbicide-resistant weeds may be identified by these indicators: 
o Failure to control a weed species normally controlled by the herbicide at the dose applied, especially if control is 
achieved on adjacent weeds; 
o A spreading patch of non-controlled plants of a particular weed species; and 
o Surviving plants mixed with controlled individuals of the same species. 
Additionally, users should follow as many of the following herbicide resistance management practices as is practical: 
• Use a broad-spectrum soil-applied herbicide with other sites of action as a foundation in a weed control program. 
• Utilize sequential applications of herbicides with alternative sites of action. 
• Rotate the use of this product with non-Group 14 herbicides. 
• Avoid making more than two applications of 14 and any other Group 14 herbicides within a single growing season unless 
mixed with an herbicide with a different site of action with an overlapping spectrum for the difficult-to-control weeds. 
• Incorporate non-chemical weed control practices, such as mechanical cultivation, crop rotation, cover crops and weed-
free crop seeds, as part of an integrated weed control program. 
• Use good agronomic principles that enhance crop development and crop competitiveness. 
• Thoroughly clean plant residues from equipment before leaving fields suspected to contain resistant weeds. 
• Manage weeds in and around fields, during and after harvest to reduce weed seed production. 
 
PRODUCT INFORMATION 
WC-SLZ herbicide is a selective soil -applied herbicide for the control of susceptible broadleaf, grass and sedge weeds. WC -SLZ 
herbicide is formulated as a 75% water dispersible granule containing the active ingredient, sulfentrazone. If adequate moisture 
(1/2" to 1") from rainfall or irrigation is not received within 7 to 10 days after the treatment of WC-SLZ herbicide , a shallow 
incorporation may be needed to obtain desired weed control. When activating moisture is received after dry conditions, WC-SLZ 
herbicide will provide a reduced level of control of susceptible germinating weeds. Soil applications of WC -SLZ herbicide must be 
made before crop seed germination to prevent injury to the emerging crop seedlings. When applications after planting are delayed, 
injury may occur if seeds are germinating or if they are located near the soil surface. Under extended periods of dry weather, adequate 
weed control may not be achieved. 
 
Observe all instructions, crop restrictions, mixing directions, application precautions, replanting directions, rotational cr op guidelines 
and other label information of each product when tank mixing with WC-SLZ herbicide. 
 
Proper handling instructions: WC-SLZ herbicide may not be mixed or loaded within 50 feet of any wells (including abandoned wells 
and drainage wells), sinkholes, perennial or intermittent streams and rivers, and natural or impounded lakes and reservoirs. This 
setback does not apply to properly capped or plugged abandoned wells and does not apply to impervious pads or properly diked 
mixing/loading areas. 
 
Operations that involve mixing, loading, rinsing, or washing of this product into or from pesticide handling or application equipment or 
containers within 50 feet of any well are prohibited unless conducted on an impervious pad constructed to withstand the weight of the 
heaviest load that may be positioned on or moved across the pad. Such a pad shall be designed and maintained to contain any 
product spills or equipment leaks, container or equipment rinse or washwater, and rainwater that may fall on the pad. Surface water 
shall not be allowed to either flow over or from the pad, which means the pad must be self -contained. The pad shall be sloped to 
facilitate material removal. An unroofed pad shall be of sufficient capacity to contain at a minimum 110% of the capacity of the largest 
pesticide container or application equipment on the pad. A pad that is covered by a roof of sufficient size to completely exclude 
precipitation from contact with the pad shall have a minimum containment capacity of 100% of the capacity of the largest pest icide 
container or application equipment on the pad. Containment capacities as described above shall be maintained at all times. The above 
specific minimum containment capacities do not apply to vehicles when delivering pesticide shipments to the mixing/loading si te. 
States may have in effect additional requirements regarding wellhead setbacks and operational containment.

Product must be used in a manner that will prevent back siphoning in wells, spills or improper disposal of excess pesticide, spray 
mixtures or rinsates. 
 
PRODUCT APPLICATION INSTRUCTIONS 
WC-SLZ herbicide may be applied to soil as a preplant incorporated treatment or as a pre- emergence (prior to weed and/or crop 
emergence) surface application. Additional application methods include post -plant treatments, over -the-top and layby, in various 
crops. Application methods are defined in the following Crop Use Directions sections. 
 
Preplant incorporated treatments require a uniform surface application followed by incorporation. Do not incorporate to a depth greater 
than 2 inches which may result in poor weed control. Care must be taken not to create overlaps in treated zones due to soil movement, 
which will result in excessive WC-SLZ herbicide rates that could result in adverse crop response. 
 
All soil applications and the residual activity of post-plant applications of WC-SLZ herbicide require adequate moisture for herbicidal 
activation. The ultimate amount of moisture, whether supplied by rainfall or irrigation, is dependent on several factors. These factors 
include but are not limited to existing soil moisture at application, soil type, organic matter and tilth. In crop situations dependent on 
rainfall, WC-SLZ herbicide can await activating moisture for extended periods (10 to 14 days or longer) depending on the soil 
parameters described above. Once activated, WC-SLZ herbicide will provide activity on existing weeds. The level of activity will depend 
on the weed species and their size at time of activation. Where irrigation is not available and rainfall has not provided act ivation, 
particularly for surface applications of WC-SLZ herbicide, a shallow incorporation is recommended for destruction of any germinating 
weeds and to incorporate WC-SLZ herbicide. Herbicide incorporation will initiate the process of activation with existing soil moisture. 
In circumstances where prolonged periods without rainfall and/or irrigation is not possible, alternative or additional weed management 
practices (cultivation or post-applied herbicides) may be required. 
 
Extreme care must be exercised and the Crop Specific Use Directions followed exactly in crops allowing post plant applications of 
WC-SLZ herbicide. Over-the-top and lay-by applications will provide contact and residual weed control, depending on species. T he 
addition of surfactants may increase contact weed control performance but may also increase the risk of adverse crop response as 
well. 
 
WC-SLZ HERBICIDE PRODUCT USE RATES 
The following directions for the selection of WC-SLZ herbicide application rates are critical to achieve maximum performance and to 
ensure maximum crop safety. The user is required to read and follow the specific WC-SLZ herbicide use directions and restrictions 
for each crop as defined in subsequent sections of this label. The user is cautioned that some crops respond differently to WC-SLZ 
herbicide. This response is governed by the WC-SLZ herbicide application rate, various soil factors and inherent crop sensitivity. The 
Crop Specific Use Directions have been desi gned to minimize the risk of adverse crop response while maintaining optimum weed 
control. 
 
Mode of Action 
Sulfentrazone, the active ingredient in WC-SLZ herbicide, is a potent inhibitor of the enzyme Protoporpyrinogen Oxidase IX (PPO IX) 
required for the formation of chlorophyll. Inhibition of PPO IX enzyme results in the liberation of singlet oxygen (O) that, in turn, disrupts 
cellular membranes and causes cellular leakage. The ultimate manifestation of the process is cellular death leading to plant death. 
The selective herbicidal activity of sulfentrazone is based on its greater affinity for the PPO IX enzyme in weed species ver sus crop 
plants. 
 
Mechanism of Action 
Following the application of WC-SLZ herbicide to soil, germinating seeds and seedlings take up sulfentrazone from the soil solution. 
The amount of sulfentrazone in soil solution, and available for weed uptake, is determined primarily by soil type, organic ma tter and 
soil pH. Sulfentrazone adsorbs to the clay and organic matter (OM) fractions of soils; effectively limiting the amount of active ingredient 
immediately available to control weeds. Soils typically increase in clay content through the series from coarse to fine as noted in the 
following Soil Classification Chart.

Influence of Soil type, organic matter and pH on WC-SLZ herbicide Use Rates and Crop Response 
Soil organic matter content can vary widely and independently of soil type and requires an accurate analysis of representativ e soil 
samples to determine its content. 
 
Soil pH also exerts a dramatic effect on sulfentrazone availability in the soil solution. As soil pH increases, sulfentrazone availability 
increases. Accurate soil pH information will require an accurate analysis of representative soil samples. 
 
The total amount of sulfentrazone available in solution, in any given soil, is determined by the interaction of soil type (particularly clay 
content), % organic matter and pH. The application timing (relative to the emergence of the crop and weeds) and am ount of rainfall 
and/or irrigation received will ultimately determine, in conjunction with the soil parameters and pH, the amount of sulfentrazone in soil

solution. It is important to note that WC-SLZ herbicide can await activating moisture. However, diminished weed control may result 
due to the successive increase in weed growth versus timing of activation. 
 
It is important to note that irrigation with highly alkaline water (high pH) following an WC-SLZ herbicide soil application can also 
significantly increase the amount of sulfentrazone available in the soil solution. Irrigation with water having a pH greater than 7.5 could 
result in adverse crop response. This response will ultimately depend on initial WC-SLZ herbicide application rate, timing, amount and 
pH of irrigation water and sensitivity of the crop and its growth stage when irrigated. The risk of adverse crop response will lessen with 
the advance in growth stage among most crops. 
 
The following Crop Specific Use Directions have been designed with specific WC-SLZ herbicide instructions for each crop based on 
the soil type, soil organic matter, and soil pH interactions described above. The user is cautioned that crop tolerance and weed control 
performance are based on strict adherence to these instructions. 
 
SPRAY DRIFT 
Ground Application 
• For ground boom spraying, the maximum release height must be 30 inches from the soil. 
• Ground applicators must use a minimum finished spray volume of 10 gallons per acre. 
• When sulfentrazone is tank mixed with a contact burndown herbicide, use a minimum spray volume of 15 gallons per acre. 
• Select nozzles and application pressure that deliver medium to coarse or larger spray droplets as indicated in the nozzle 
manufacturer’s recommendations and in accordance with ASABE S-572. 
• Select coarse to very coarse droplet size when sulfentrazone is used as a preemergent/preplant application. 
• Select medium to very coarse droplet size when sulfentrazone is used postemergence with a contact burndown herbicide. 
• Do not apply spray droplets smaller than medium size. 
• Applicators may spray only when wind speed is between 3 and 10 mph. 
 
Aerial Application 
• Aerial application is allowed only when the field is too wet to safely apply pesticides using ground equipment. 
• When this product is allowed to be applied by air, applicator must use a minimum finished spray volume of 5 gallons per acre. 
• 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. 
• Select nozzles and application pressure that deliver medium to coarse or larger spray droplets as indicated in the nozzle 
manufacturer’s recommendations and in accordance with ASABE Standard S-572. 
• Select coarse to very coarse droplet size when sulfentrazone is used as a preemergent/preplant application. 
• Select medium to very coarse droplet size when sulfentrazone is used postemergence with a contact burndown herbicide. 
• Do not apply as spray droplets smaller than medium size. 
• Applicators may spray only when wind speed is between 3 and 10 mph. 
 
 
The following drift management requirements must be followed to avoid off -target movement from aerial applications. These 
requirements do not apply to forestry applications, public health uses or to applications of dry materials. 
1. The distance of the outermost nozzles on the boom must not exceed ¾ the length of the wingspan or rotor. 
2. Nozzles must always point backward parallel with the air stream and never be pointed downwards more than 45 degrees. 
3. Observe the regulations of the State where applications are made. 
 
 
 
 
SPRAY DRIFT REDUCTION ADVISORIES 
THE APPLICATOR IS RESPONSIBLE FOR AVOIDING OFF-SITE SPRAY DRIFT. 
BE AWARE OF NEARBY NON-TARGET SITES AND ENVIRONMETAL CONDITONS. 
 
 
 
Information on Droplet Size 
The most effective way to reduce drift potential is to apply large droplets. The best drift management strategy is to apply the largest 
droplets that provide sufficient coverage for pesticide performance. Applying larger droplets reduces drift potential but will not 
prevent drift if applications are made improperly or under unfavorable environmental conditions. (See information on Wind, 
Temperature and Humidity, and Temperature Inversions in subsequent sections). 
 
 
Controlling Spray Droplet Size 
Volume – Use high flow rate nozzles to apply the greatest practical spray volume. Nozzles with higher rated flow generally produce 
larger droplets. 
 
Pressure - When higher flow rates are needed, use higher flow rate nozzles rather than increasing spray pressure. 
 
Do not exceed the nozzle manufacturer’s recommended pressures. Lower pressure produces larger droplets in many types of 
nozzles. 
 
Number of Nozzles – Use the minimum number of nozzles that provide uniform coverage. 
 
Nozzle Orientation – For aerial application, the recommended practice is to orient nozzles so that the spray is released parallel to 
the airstream. This orientation usually produces larger droplets as compared to other nozzle orientations. Significant nozzle deflection 
from horizontal will reduce droplet size and increase drift potential.

Page 6 
Nozzle Type - Use a nozzle type that is designed for the intended application. With most nozzle types, narrower spray angles produce 
larger droplets. Consider using low drift nozzles for both ground and aerial applications. Solid stream nozzles oriented straight back 
usually produce the largest droplets and the lowest drift potential in aerial applications 
 
Boom Length – For some aerial use patterns, reducing the effective boom length to less than ¾ of the wingspan or rotor length may 
further reduce drift without reducing swath width. 
 
Application Height - Aerial applications should not be made at a height greater than 10 feet above the top of the target plant canopy 
unless a greater height is required for aircraft safety. Making applications at the lowest height that is safe reduces exposure of droplets 
to evaporation and wind. 
 
Swath Adjustment – When aerial applications are made with a crosswind, the swath will be displaced downwind. Therefore, on the 
upwind and downwind edges of the field, the applicator must compensate for this displacement by the path of the aircraft upwi nd. 
Swath adjustment or offset distance should increase when conditions favor increased drift potential (higher winds, smaller droplets, 
etc). 
 
Wind – Drift potential is lowest between wind speeds of 3-10 mph. However, many factors, including droplet size and equipment type 
determine drift potential at any given wind speed. Application should be avoided below 3 mph due to variable wind direction and high 
inversion potential. NOTE: Local terrain can influence wind patterns. Every applicator should be familiar with local wind patterns and 
how they may potentially affect spray drift. 
 
Temperature and Humidity – When making applications in low relativ e humidity, set up equipment to produce larger droplets to 
compensate for evaporation. Droplet evaporation is most severe when conditions are both hot and dry. 
 
Temperature Inversions – Applications should not occur during a temperature inversion because drift potential is high. Temperature 
inversions restrict vertical air mixing, which causes small-suspended droplets to remain in a concentrated cloud. This cloud can move 
in unpredictable directions due to the low speed and variable winds common during i nversions. Temperature inversions are 
characterized by increasing temperatures with altitude and are common during conditions of limited cloud cover and little to no wind. 
They often begin to form as the sun sets and may often continue into the morning. The presence of a temperature inversion may be 
indicated by ground fog. However if fog is not present, the movement of smoke from a ground source or an aircraft smoke generator 
can also identify inversions. Smoke that remains in layers and moves lateral ly in a concentrated cloud (under low speed wind 
conditions) indicates an inversion, while smoke that moves upward and rapidly dissipates indicates good vertical air mixing. 
 
Sensitive Areas – The pesticide should only be applied when the wind is blowing away from sensitive areas (e.g. residential areas, 
bodies of water, known habitat for threatened or endangered species, non-target crops). 
 
Off-Target Movement of WC-SLZ herbicide 
Drift of dilute spray mixtures containing WC-SLZ herbicide must be prevented. Observation of the preceding environmental conditions, 
correct application equipment design, calibration and application practices will significantly diminish the risk of off -target spray drift. 
WC-SLZ herbicide can cause significant symptomology by drift on to sensitive crops and other plants. This symptomology may 
manifest initially as discreet, localized spots where contacted by WC-SLZ herbicide drift mixtures. Depending on concentration of the 
spray solution and droplets size (effectively determining the dosage of sulfentrazone) and also depending on the inherent sen sitivity 
of the plants involved, these spots or lesions may or may not coalesce. These effects will usually not have lasti ng effects on plant 
growth, but will likely reduce the value of affected fruit or foliage where grade or quality is associated with appearance. In severe drift 
instances with particularly sensitive crops, defoliation of affected foliage could result. Failure to follow these guidelines and 
environmental prohibitions that then result in off -target movement or drift of WC-SLZ herbicide on to unintended crops or plants, 
irrespective of severity, constitutes misapplication of this product. FMC accepts no respons ibility or liability for potential crop effects 
that may result from such misapplication of WC-SLZ herbicide. 
 
Chemigation Application 
 WC-SLZ herbicide may be applied through sprinkler irrigation systems including center pivot, lateral move, end tow, solid set, or hand 
move irrigation systems. Do not apply this product through any other type of irrigation system. Do not connect any irrigation system 
(including greenhouse systems) used for pesticide application to a public water system. Crop injury, lack of effectiveness or illegal 
residues on or in the crop can result from non-uniform distribution of treated water. If you have questions about calibration, you should 
contact State Extension Service specialists, equipment manufacturers, or other experts. A person knowledgeable of the chemigation 
system and responsible for its operation, or under the supervision of the responsible person, shall shut the system down and make 
necessary adjustments should the need arise. 
 
It is important to note that irrigation with highly alkaline water (high pH) following a WC -SLZ herbicide soil application can also 
significantly increase the amount of sulfentrazone available in soil sol ution. Irrigation with water having a pH greater than 7.5 could 
result in adverse crop response. This response will ultimately depend on initial WC-SLZ herbicide application rate, application timing, 
amount and pH of the irrigation water, and the sensitivi ty of the crop and the growth stage when irrigated. The risk of adverse crop 
response will lessen with advancing growth stages of most crops. 
 
The system must contain a functional check valve, vacuum relief valve, and low-pressure drain appropriately located on the irrigation 
pipeline to prevent water source contamination from backflow. The pesticide injection pipeline must also contain a functional, 
automatic, quick-closing check valve to prevent the flow of fluid back toward the injection pump. The pesticide injection pipeline must 
also contain a functional, normally closed, solenoid-operated valve located on the intake side of the injection pump and connected to 
the system interlock to prevent fluid from being withdrawn from the supply tank when the i rrigation system is either automatically or 
manually shut down. The system must contain functional interlocking controls to automatically shut off the pesticide injecti on pump 
when the water pump motor stops. The irrigation line or water pump must include a functional pressure switch, which will stop the 
water pump motor when the water pressure decreases to the point where pesticide distribution is adversely affected. 
 
Systems must use a metering pump, such as a positive displacement injection pump (e.g., diaphragm pump) effectively designed and 
constructed of materials that are compatible with pesticides and capable of being fitted with a system interlock.

Page 7 
WC-SLZ herbicide should be metered into the irrigation system continuously for the duration of the water application. WC-SLZ 
herbicide should be diluted in sufficient volume to ensure accurate application over the area to be 
treated. Use the appropriate amount of water to carry the product to the soil surface. Continuous agitation is required to maintain 
product suspension in the solution tank. A jar test should be conducted to ensure that phase separation would not occur duri ng 
dilution and application. Failure to achieve a uniform dilution throughout the time of application may result in undesirable residues or 
less than desirable weed control. Flush the lines at the completion of the application and then turn the water off promptly. 
 
When using water from public water systems; DO NOT APPLY WC-SLZ herbicide THROUGH ANY IRRIGATION SYSTEM 
PHYSICALLY CONNECTED TO A PUBLIC WATER SYSTEM. Public water system means a system for the provision to the public 
of piped water for human consumption if such system has at least 15 service connections or regularly serves an average of at least 
25 individuals daily at least 60 days of the year. WC-SLZ herbicide may be applied through irrigation systems, which may be supplied 
by a public water system only if water from the water system is discharged into a reservoir tank prior to pesticide introduction. There 
shall be a complete physical break (air gap) between the outlet end of the fill pipe and to top or overflow rim of the reservoir tank of at 
least twice the inside diameter of the fill pipe. Before beginning chemigation, always make sure that the air gap exists and that there 
is no blockage of the overflow of the reservoir tank. 
 
Application with Liquid Fertilizer 
WC-SLZ herbicide may be applied using liquid fertilizer solutions as the carrier. The fertilizer solutions may either be concentrate 
formulations as blended or diluted with water. When applied as directed with adequate soil coverage, WC-SLZ herbicide applied with 
liquid fertilizer mixtures will provide satisfactory weed control. However, adequate soil coverage is essential to achieve acceptable 
levels of weed control. 
 
Herbicide mixing, solution stability and/or compatibility problems can occur when liquid fertilizers are used as a carrier. Compatibility 
tests must be conducted prior to mixing to ensure tank mixture compatibility and stability. The use of compatibility agents may be 
beneficial to achieve and maintain a homogenous solution. 
 
Mixing Instructions for Liquid Fertilizer Applications 
Fill the clean spray tank to one half of the total volume with the fertilizer solution. Start the spray tank agitation syste m. Prepare a 
slurry of WC-SLZ herbicide in a clean container with clean water using equal volumes of WC-SLZ herbicide and clean water. Slowly 
add the WC-SLZ herbicide/water slurry to the spray tank. Carefully rinse the slurry container, adding the rinsate to the spray tank. 
Better mixing of the WC-SLZ herbicide/water slurry may be achieved if the slurry is added using induction systems on the sprayer fill 
plumbing system. 
 
Complete filling the spray tank to the desired level. Sufficient and continuous spray tank agitation is required at all times to maintain 
a homogenous spray solution. The spray system must be designed such that there is sufficient flow capacity to uniformly apply the 
spray mixture and maintain adequate tank agitation. Some systems may require separate pumps to simultaneously supply the spray 
system and the spray tank agitation system. Ensure the WC-SLZ herbicide slurry is thoroughly mixed before application. 
 
For tank mixtures with other herbicide(s), a compatibility test must be conducted to ensure product compatibility before mixing. Read 
and follow all the directions, precautions and restrictions of the tank mixture products prior to mixing. 
 
Apply the WC-SLZ herbicide spray mixture immediately after mixing. Do not store the sprayer overnight or for any extended period of 
time with the WC-SLZ herbicide spray mixture remaining in the tank. 
 
 
Do not premix WC-SLZ herbicide spray solutions in nurse tanks. 
 
Follow all WC-SLZ herbicide label directions regarding product use rates per acre, registered crops, application instructions, 
incorporation directions, special instructions and all precautions. 
 
All individual state regulations relating to liquid fertilizer blending, storage, transportation, registration, labeling, and application are the 
responsibility of the individual and/or company preparing, selling or applying the WC-SLZ herbicide and fertilizer mixture.

MIXING AND LOADING INSTRUCTIONS 
WC-SLZ herbicide may be applied alone, or in tank mixtures with other herbicides for the control of additional weed species. Mixtures 
with some other pesticides have not been tested. Conduct appropriate compatibility tests prior to tank mixing with other pest icides. 
Follow all precautions and restrictions on the tank mix partner label. 
 
It is important that spray equipment is clean and free of existing pesticide residues before preparing WC-SLZ herbicide spray mixtures. 
Follow the spray tank clean out procedures specified on the label of the product or products previously applied. 
 
For best results fill spray tank with one half of the volume of clean water needed for the field to be treated. Start agitati on system. 
Prepare a slurry of WC-SLZ herbicide in a clean container using clean water. Slowly add the WC-SLZ herbicide/water slurry to the 
spray tank. Carefully rinse the slurry container, adding the rinsate to the spray tank. Complete filling the spray tank to the desired 
level. Continuous spray tank agitation is required at all times to maintain a uniform spray solution. Make sure WC-SLZ herbicide is 
thoroughly mixed before application or before adding another product to the spray tank. 
 
Use the WC-SLZ herbicide spray mixture immediately after mixing. Do not store the sprayer overnight or for any extended period of 
time with the WC-SLZ herbicide spray mixture remaining in the tank.

Page 10 
Do not premix WC-SLZ herbicide spray solutions in nurse tanks. 
 
If WC-SLZ herbicide is tank mixed with other herbicides, all additional directions, restrictions and precautions for the tank mixture 
herbicides must be followed. 
 
SPRAYER EQUIPMENT CLEAN-OUT 
As soon as possible after spraying WC -SLZ herbicide and before using sprayer equipment for any other applications, the 
sprayer must be thoroughly cleaned to avoid potential crop affects using the following procedure. Residues left in mixing 
equipment, spray tanks, hoses, spray booms and nozzles can cause crop effects if they are not properly cleaned. In addition, 
users must take appropriate steps to ensure proper equipment clean -out for any other products mixed with WC-SLZ 
herbicide 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. 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 opera tion 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. Remove and clean spray tips and all filters and screens (tank, spray hose 
and spray tip) separately in an ammonia solution. 
 
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. 
 
Do not store the sprayer overnight or for any extended period of time with WC -SLZ herbicide 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. 
 
Should small quantities of WC-SLZ herbicide 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. 
 
Do not drain of flush equipment on or near desirable trees or plants. 
 
Do not contaminate any body of water including irrigation water that may be used on other crops.

Fall Application (MN, ND, SD, MT, CO, NE, WY, ID, WA, OR, WI, MI) 
WC-SLZ herbicide may be applied in the fall following crop harvest or in existing fallow fields to control or suppress weeds the following 
season. The WC-SLZ herbicide Rotational Crop Guidelines Table must be followed if crops are planted the next season. WC-SLZ 
herbicide should be applied to the harvested crop stubble or soil surface without incorporation. Moisture in the form of rain or snow 
will move and activate the product. Do not mechanically incorporate in the fall or spring after application because this activity may 
destroy the herbicide barrier and weed escapes can occur. Do not apply to frozen soils to prevent WC-SLZ herbicide runoff from rain 
or snow that may occur following application. WC -SLZ herbicide may be tankmixed with herbicides to control emerged weeds. 
Sequential applications may be needed depending on weed size. In situations where weed size may interfere with WC-SLZ herbicide 
reaching the soil surface, a separate burndown application prior to the application of WC-SLZ herbicide will be required. Use listed 
rates of burndown herbicides in combination with WC -SLZ herbicide, or sequential applications as needed. H igher aerial spray 
volumes are required when there is a dense weed population or canopy. 
WC-SLZ herbicide can be tankmixed with other herbicides. Observe all precautions, instructions, and rotational cropping guidelines 
of each product’s label when tank mixing, including all references to potential carryover and crop injury warnings or restrictions. 
 
Spring Preemerge Application 
WC-SLZ herbicide may be applied as a fallow treatment early in the spring provided the application is made prior to weed emergence, 
and adequate moisture is available to activate the WC -SLZ herbicide. Follow the same use rate specifications and application 
guidelines listed under the Fall Application section above.

Use higher rates for soils of pH less than 7.0 and lower rates for pH greater than 7.0 within the rate range. 
 
Ground and Aerial Applications 
Apply WC-SLZ herbicide in conventional tillage, conservation tillage, reduced tillage or no-tillage cropping systems using rates listed 
in the WC-SLZ herbicide Use Rate table above. WC-SLZ herbicide may be applied with ground or aerial sprayers calibrated to deliver 
a minimum of 10 gallons of finished spray by ground application and 5 gallons of finished spray by air. Use nozzle types and 
arrangements that will provide optimum coverage while producing a minimal amount of fine droplets. Apply sufficient spray volume to 
achieve adequate coverage. 
 
Preplant Incorporated and Preemergence Applications 
 WC-SLZ herbicide can be applied prior to planting or up to 3 days after planting. When applications after planting are delayed greater 
than 3 days after planting, injury may occur if seeds are germinating. WC-SLZ herbicide may be applied preemergence or preplant 
incorporated. For preplant incorporated applications, incorporation must be uniform and no deeper than 2 inches. Improper soil 
incorporation may result in erratic weed control and/or crop injury. WC -SLZ herbicide applied near or after crop emergence may 
cause severe injury to the crop. WC-SLZ herbicide can be applied alone or in combination with other labeled soybean herbicides. 
WC-SLZ herbicide may be followed by labeled postemergence soybean herbicides for increased control of grass and broadleaf weeds. 
Always follow the most restrictive label when tank mixing. When using WC-SLZ herbicide in no-till or minimum till cropping systems, 
tank mix with an appropriate burndown herbicide for improved control of existing weeds. 
 
Fall Applications 
 WC-SLZ herbicide may be applied as a fall treatment to the stubble of harvested crops for the burndown of existing vegetation and 
preemergence control of labeled weeds the following spring in no-till and conservation tillage production systems. Fall applications of 
WC-SLZ herbicide must be made in weed control programs that include, as needed, spring applications of preplant, preemergence 
or postemergence herbicides for the following crop season. WC-SLZ herbicide can be applied to the stubble of a harvested crop in 
no-till or to the soil surface of conservation tillage fields after harvest when the sustained soil temperature is 55 degrees F and falling 
at a soil depth of 4 inches. Apply after September 30 in those areas North of Interstate 90 and after October 15 in those areas North 
of Interstate 70. Do not apply WC-SLZ herbicide as a fall treatment South of Interstate 70. Applications to ridge till production systems 
must be made after the formation of ridges or bedded. 
 
If weeds are emerged at the time of application, utilize a tank mixture with a suitable burndown herbicide at labeled rates. Fall applied 
burndown treatments should be made with a minimum of 20 gallons per acre to achieve adequate coverage of the weeds being 
treated. When making burndown applications to emerged weeds, the addition of adjuvants such as COC or MSO to the spray mixture 
can be used to enhance the burndown activity of the application. 
 
Weeds Controlled 
When Applied according to directions, WC-SLZ herbicide will provide control of: 
Amaranth, Palmer Nightshade 
Copperleaf, hophornbeam Pigweed, spp. 
Kochia (ALS and Triazine Resistant) Sida, prickly 
Lambsquarters, common Thistle, Russian 
Morningglory, spp. Waterhemp, spp. 
 
When applying WC -SLZ herbicide with other registered herbicides, refer to specific label information on precautions, instructions, 
limitations, application methods and timings, and weeds controlled. 
 
WC-SLZ herbicide is especially effective against a wide range of economic broadleaf and grass weeds. The same processes that 
sulfentrazone affects in these weeds can, under certain conditions, be affected in soybeans. These conditions include high pH (7.5 
and above), cool weather, prolonged and excessive moisture, seedling diseases, and any other condition, including poor agronomic 
practices, that are unfavorable to vigorous crop growth. Such effects in soybeans are often observed as stunting and discolor ation. 
The duration of these effects are somewhat dependent on the duration of the adverse growing conditions. These effects lessen and 
generally diminish with the return to normal growing conditions. 
 
These Crop Specific Use directions are based upon the interactive effects of WC-SLZ herbicide (sulfentrazone) and the primary soil 
and environmental factors, which affect its activity on various weed species and tolerance among crops. The user is required to 
observe the instructions and guidance previously presented under Product Application Instructions, WC-SLZ herbicide Product Use 
Rates, Rotational Crop Guidelines, Replanting Instructions, Weed Controlled and any other section of this label pertinent to the 
anticipated crop use. It is important to note that not all varieti es or cultivars of a given crop species have been evaluated under 
treatment with WC-SLZ herbicide. Consult university or extension weed management specialists for additional information on specific 
local varieties or cultivars and any other pertinent information on WC-SLZ herbicide under specific local conditions.

Fall Applications 
WC-SLZ herbicide may be applied in the fall as a preplant treatment to control or suppress weeds prior to planting sunflowers the 
following spring. WC-SLZ herbicide should be applied to the stubble or soil surface and allow moisture from rainfall or snow to move 
the product into the soil. Do not mechanically incorporate in the fall or spring as this can destroy the herbicide barrier and allowing 
weed escapes to occur. Do not apply to frozen soils or to existing snow cover to prevent WC-SLZ herbicide runoff from rain or snow 
melt that may occur following application. WC-SLZ herbicide may be tank mixed with other residual soil herbicides that are labeled 
for fall use on sunflowers. If weeds are emerged at the time of WC -SLZ herbicide application, use a burndown herbicide such as 
glyphosate or paraquat at the full -labeled rate in combination with WC-SLZ herbicide or split application as needed. Select the 
appropriate rate from table above within the correct soil type and organic matter range. When applying WC-SLZ herbicide in the fall, 
use a mid to high rate within the rate range for the appropriate soil type and organic matter. 
 
Early Preplant and Preemergence (Spring Applications) 
WC-SLZ herbicide may be applied preplant on the soil surface in the spring to control weeds in sunflowers. WC-SLZ herbicide can 
be applied early preplant prior to planting up to 3 days after planting as a preemerge soil application if seedlings have not broken the 
soil surface and if the seed furrow is completely closed. For preemerge applications greater than 3 weeks prior to planting, use the 
high rate within the appropriate rate range for the soil and organic matter type listed in the use rate chart above. If applying WC-SLZ 
herbicide to coarse textured soils with less than 1.5% organic matter, wait a minimum of 7 days after application before planting. WC-
SLZ herbicide can be tank mixed with other preemerge herbicides labeled for sunflower. If dry conditions persist following preemerge 
application of WC-SLZ herbicide, a shallow incorporation may be needed to incorporate and activate the herbicide. If weeds are 
emerged at the time of WC-SLZ herbicide application, use a burndown herbicide at the full-labeled rate in combination with WC-SLZ 
herbicide or split application as needed. 
 
Preplant Incorporated (PPI) 
WC-SLZ herbicide may be applied as a Preplant Incorporated treatment in the spring prior to planting in reduced and conventional 
tillage. WC-SLZ herbicide should be shallowly incorporated in the soil no deeper than 2 inches. Incorporating WC -SLZ herbicide 
deeper than 2 inches can result in inconsistent weed control. Use the appropriate rate from table above for the soil texture, organic 
matter, and pH level. WC-SLZ herbicide can be tankmixed with other soil -applied herbicides labeled for preplant incorporation in 
sunflowers. 
Weeds Controlled 
When applied according to directions, WC-SLZ herbicide will provide control of: 
Amaranth, Palmer Pigweed, red root 
Filaree, redstem Pigweed, smooth 
Kochia (ALS and Triazine Resistant) Sida, prickly 
Lambsquarters, common Thistle, Russian 
Morningglory, ivyleaf Waterhemp, common 
Morningglory, tall Waterhemp, tall 
Nightshade, Eastern black 
 
Under extended periods of dry weather, adequate weed control may not be achieved 
 
Some adverse crop response may occur on coarse textured soils with low organic matter (less than 1.5%) and pH of 7.8 or higher, or 
on highly eroded soils, or in areas of calcareous outcroppings. WC-SLZ herbicide use rates should be reduced in those areas . 
Inadequate seed furrow closure or shallow planting (less than 1.0 inch) may result in undesirable crop response. As expected, poor 
growing conditions such as excessive moisture, low temperatures, soil compaction and diseases may also cause undesirable crop 
response. 
 
These Crop Specific Use directions are based upon the interactive effects of WC-SLZ herbicide (sulfentrazone) and the primary soil 
and environmental factors, which affect its activity on various weed species and tolerance among crops. The user is required to 
observe the instructions and guidance previously presented under Product Application Instructions, WC-SLZ herbicide Product Use 
Rates, Rotational Crop Guidelines, Replanting Instructions, Weed Controlled and any other section of this label pertinent to the 
anticipated crop use. It is important to note that not all varieties or cultivars of a given crop species have been evaluated under 
treatment with WC-SLZ herbicide. Consult university or extension weed management specialists for additional information on specific 
local varieties or cultivars and any other pertinent information on WC-SLZ herbicide under specific local conditions.

WC-SLZ herbicide may be surface applied or preplant incorporated (to a depth no greater than 2 inches) from 14 days to 12 hours 
days prior to transplanting tobacco. Incorporating WC-SLZ herbicide deeper than 2 inches can result in inconsistent weed control. 
 
Broadcast apply the appropriate WC-SLZ herbicide rate from table above, in a minimum of 10 gallons per acre of water, to the soil 
prior to transplanting. 
 
Non-Bedded (Fields where raised beds are NOT formed prior to transplanting) 
Perform all accepted cultural practices for land preparation, fertilizer/fungicide incorporation, etc. prior to the applicati on of WC-SLZ 
herbicide. Once the field has been prepared for planting, WC-SLZ herbicide may be surface applied or lightly preplant incorporated 
from 14 days to 12 hours prior to transplanting. 
 
If WC-SLZ herbicide is surface applied and it is necessary to remove equipment tracks from the field after application but prior to 
transplanting, any light finishing equipment may be used providing the soil is not disturbed to a depth greater than 2 inches. 
 
If timely cultivations are not performed following a pre-transplant surface application, reduced/unacceptable weed control may occur 
in the drill. 
 
Bedded (Fields where raised beds ARE formed PRIOR to transplanting) 
Apply WC-SLZ herbicide to formed beds as a surface application from 14 days to 12 hours prior to transplanting. If it is customary to 
drag/knock down beds prior to transplanting, this procedure must be performed prior to the WC-SLZ herbicide application. 
 
When incorporating prior to bedding, WC-SLZ herbicide must be thoroughly and uniformly incorporated to a depth no greater than 2 
inches to avoid concentrating WC-SLZ herbicide in the bed. 
 
If initial transplanting fails to produce a uniform stand, tobacco may be replanted. DO NOT re-treat field with a second application of 
WC-SLZ herbicide, or any other herbicide containing sulfentrazone. DO NOT re-bed. Re-transplant into previously formed, treated 
beds. 
 
For broad spectrum and optimum grass weed control a grass herbicide application will be required. 
 
 
Weeds Controlled 
When Applied according to directions, WC-SLZ herbicide will provide control of: 
Amaranthus, livid Pigweed, redroot 
Filaree, redstem Pigweed, smooth 
Galinsoga, hairy Sida, prickly 
Lambsquarters, common Signalgrass, broadleaf 
Morningglory, ivyleaf Smartweed, Pennsylvania 
Morningglory, tall 
 
 
Poor agronomic practices, unfavorable pH soils, diseases, cold weather, excessive moisture, drought or other conditions unfavorable 
to normal plant growth may adversely affect the growth of tobacco transplants. Weakened transplants may be more susceptible to 
herbicide response and diseases, particularly under poor drainage or compacted soil conditions or when the soil has been saturated 
for long periods of time. Contact your State Agricultural Extension Service Specialist for consultation as to the agronomic 
recommendations suited for your tobacco varieties and local conditions. Temporary stunting of tobacco may occur if transplants are 
set too shallowly, or if heavy rainfall occurs immediately following transplanting. Splashing of treated soil onto tobacco l eaves may 
cause some localized and inconsequential necrosis. Use sound transplanting practices that ensure treated soil will not wash or crust 
over tobacco plants.

NEW STRAWBERRY PLANTINGS 
Preemergence 
WC-SLZ herbicide can be applied prior to planting and before seedlings have emerged. WC -SLZ herbicide applied after crop 
emergence may cause severe injury to the crop. WC -SLZ herbicide can be applied alone or in combination with other labeled 
strawberry herbicides. WC-SLZ herbicide may be followed by labeled postemergence strawberry herbicides for increased control of 
grass and broadleaf weeds. Always follow the most restrictive label when tank mixing. When using WC-SLZ herbicide in no-till or 
minimum till cropping systems, tank mix with an appropriate burndown herbicide for improved control of existing weeds. 
 
ESTABLISHED STRAWBERRY PLANTINGS 
Dormant Established Strawberry 
Apply to established strawberry stands at dormancy. WC-SLZ herbicide applications to desirable foliage may cause severe crop 
injury. If emerged weeds are present at the time of application, tank mix WC-SLZ herbicide with another herbicide labeled for use 
in strawberries with post emergent activity. Do not apply within 56 days of harvest. 
 
Strawberry Row Middle 
Apply WC-SLZ herbicide in a band to row middles between planting beds using a hooded shielded sprayer. Do not allow spray to 
contact emerged crops. Severe crop injury will occur if spray solutions of WC-SLZ herbicide contact desirable vegetation, stems, 
fruit, or blooms. Any spray contacting strawberry foliage, flowers, or fruit will cause severe crop damage. If emerged weeds are 
present, tank mix with WC-SLZ herbicide with another herbicide labeled for use in strawberries with post emergent activity. Use a 
quality federally approved nonionic surfactant (NIS) at the rate of 0.25% v/v when applying postemerge. Do not apply within 3 days 
of harvest.

NUTSEDGE SUPPRESSION 
Common Name Scientific Name 
Nutsedge, purple Cyperus rotundus 
Nutsedge, yellow Cyperus esculentus 
WC-SLZ herbicide will aid in the management of yellow and purple nutsedge populations by weakening existing nutsedge plants. The 
degree of suppression depends on the rate of WC -SLZ herbicide applied, moisture, soil conditions, the depth of nutsedge nutlets, 
weather, and the interval between WC-SLZ herbicide application and nutsedge emergence in the spring. 
 
Soil uptake is the major means of uptake by sedges however, postemergence applications to sedges allow WC-SLZ herbicide to be 
taken into the sedge through the foliage as well as soil uptake through the roots. Good spray coverage is required for optimum control 
of sedges especially when applying postemergence to the sedges. Use a quality federally approved nonionic surfactant (NIS) at the 
rate of 0.25% v/v when applying postemergence. Best suppressive activity is attained when nutsedge plants are small with 6 or fewer 
leaves.
