PRECAUTIONARY STATEMENTS
Hazards to Humans and Domestic Animals 
CAUTION
Harmful if swallowed, absorbed through skin, or inhaled. Causes moderate eye irritation. Avoid contact with skin, 
eyes, or clothing. Wash thoroughly with soap and water after handling and before eating, drinking, chewing gum, 
using tobacco, or using the toilet. Remove and wash contaminated clothing before reuse.
Personal Protective Equipment (PPE)
Applicators and other handlers must wear: long sleeved shirt and long pants, chemical resistant gloves made of any 
waterproof material such as polyethylene or polyvinyl chloride, shoes plus socks, and protective eyewear (goggles or 
face shield).
Follow manufacturer’s instructions for cleaning/maintaining PPE. If no such instructions for washables exist, use 
detergent and hot water. Keep and wash PPE separately from other laundry.
User Safety Recommendations:
Users should:
- Wash thoroughly with soap and water after handling and before eating, drinking, using tobacco, or using the toilet.
- Remove clothing immediately if pesticide gets inside. Then wash thoroughly and put on clean clothing. 
- Remove PPE/gloves immediately after handling the product. Wash the outside of gloves before removing. As soon 
as possible, wash thoroughly and change into clean clothing. 
ENVIRONMENTAL HAZARDS
This pesticide is toxic to fish, aquatic invertebrates, and to some plants at very low concentrations. Do not apply directly 
to water, to areas where surface water is present, or to intert idal areas below the mean high water mark. Drift and 
runoff from treated areas may be hazardous to terrestrial and aquatic plants in neighboring areas. Do not contaminate 
water when disposing of equipment wash waters or rinsate. 
Ground Water Advisory: The chemicals and degradation products have properties and characteristics associated 
with chemicals detected in ground water. This chemical may leach into ground water if used in areas where soils are 
permeable, particularly where the water table is shallow.
Do not use on coarse soils classified as sand, which have less than 1% organic matter.
Surface Water Advisory: Do not apply directly to water, to areas where surface water is present, or to intertidal 
areas below the mean high water mark. Drift and runoff may be hazardous to aquatic organisms in water adjacent to 
treated areas. Do not contaminate water when disposing of equipment wash waters or rinsate.
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 a high potential for reaching both 
surface water and aquatic sediment via runoff for several months or longer 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 from runoff water and sediment. Runoff of this product will be 
reduced by avoiding applications when rainfall is forecasted to occur within 48 hours.
Point Source Contamination: To prevent point source contamination do not mix or load this or any other pesticide 
within 50 feet of wells (including abandoned wells and drainage wells, sink holes, 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 pad or dike mixing/ loading areas as described below.
Mixing, loading, rinsing, or washing operations performed within 50 feet of a well are allowed only when conducted on 
an impervious pad constructed to withstand the weight of the heaviest load that may be on or move across the pad. 
The pad must be self contained to prevent surface water flow over or from the pad. The pad capacity must be 
maintained at 110% of that of the largest pesticide container or application equipment used on the pad and has
sufficient capacity to contain all products spills, equipment or container leaks, equipment wash waters and rainwater 
that may fall on the pad. The containment capacity does not apply to vehicles delivering pesticides shipments to the 
mixing/ loading site. States may have in effect additional requirements regarding wellhead setbacks and operational 
containment.

3 
 
Care must be taken when using this product to prevent back siphoning into wells, spills or improper disposal of 
excess pesticide, spray mixes, or rinsates. Check values or anti-siphoning devices must be used on all mixing 
equipment.
PHYSICAL/CHEMICAL HAZARDS
Combustible: Do not use or store near heat or open flame.
DIRECTIONS FOR USE
It is a violation of Federal law to use this product in a manner inconsistent with its labeling. Read all Directions for 
Use carefully before applying. Do not apply this product in a way that will contact workers or other persons, either 
directly or through drift. Only protected handlers may be in the area during application. For any requirements specific 
to your State or Tribe, consult the agency responsible for pesticide regulation.
FAILURE TO FOLLOW THE DIRECTIONS FOR USE AND PRECAUTIONS ON THIS LABEL MAY RESULT IN 
POOR WEED CONTROL, CROP INJURY, OR ILLEGAL RESIDUES.
RESISTANCE MANAGEMENT 
VHP58 Herbicide, which contains the active ingredients sulfentrazone and pyroxysulfone is a group 14 and 15
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 VHP58 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 FMC 
representative, local retailer, or county extension agent.
AGRICULTURAL USE REQUIREMENTS
Use this product only in accordance with its labeling and with the Worker Protection Standard, 40 CFR part 
170. This Standard contains requirements for the protection of agricultural workers on farms, forests, nurseries, 
and greenhouses, and handlers of agricultural pesticides. It contains requirements for training, 
decontamination, notification, and emergency assistance. It also contains specific instructions and exceptions 
pertaining to the statements on this label about personal protective equipment (PPE) and restricted-entry interval. 
The requirements in this box only apply to uses of this product that are covered by the Worker Protection 
Standard. 
Do not enter or allow worker entry into treated areas during the restricted entry interval (REI) of 12 hours. 
PPE required for early entry to treated areas that is permitted under the Worker Protection Standard and that 
involves contact with anything that has been treated, such as plants, soil, or water, is: Coveralls over 
long-sleeved shirt and long pants, protective eyewear (goggles or face shield), chemical resistant gloves made of 
any waterproof material such as polyethylene or polyvinyl chloride, and shoes plus socks.

· Contact your FMC representative, crop advisor, or extension agent to find out if suspected resistant 
weeds to these MOAs have been found in your region. Do not assume that each listed weed is being 
controlled by multiple sites of action. Products with multiple active ingredients are intended to broaden the 
spectrum of weeds that are controlled. Some weeds may be controlled by only one of the active ingredient 
in this product.
· If resistance is suspected, treat weed escapes with an herbicide having a site of action other than Group 
14 and 15 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:
- Failure to control a weed species normally controlled by the herbicide at the dose applied, 
especially if control is achieved on adjacent weeds;
- A spreading patch of non-controlled plants of a particular weed species; and
- 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 and 15 herbicides.
· Avoid making more than two applications of VHP58 Herbicide and any other Group 14 and 15 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 
VHP58 can be applied in all tillage systems (conventional, reduced and no-tillage) and applied in the fall or in the 
spring as a preplant, preplant incorporated, or preemergence trea tment for susceptible grass and broadleaf weeds in 
pea and bean dried shelled, except soybean (subgroup 6C), flax, soybean, and sunflowers (subgroup 20B). Consult 
individual crop sections for specific use directions and application timings for each crop.
Application Instructions and Timing:
Moisture (rainfall or irrigation) is necessary to activate the active ingredients in VHP58 in soil for weed control. Dry 
weather following applications of VHP58 may reduce the effectiveness of VHP58 . However, when adequate 
moisture is received after dry conditions, VHP58 will control susceptible germinating weeds. VHP58 may not control 
weeds that germinate after application but before an activating rainfall and/or irrigation of at least 0.5 inch, or weeds 
that germinate through cracks resulting from dry soil. When adequate moisture is not received after VHP58 
application, weed control may be improved by irrigation or shallow incorporation with rotary hoe or other light tillage.
If no rain occurs within 7 days after application, apply overhead irrigation if available at 0.5 to 1.0 inch total volume. 
Refer to the crop specific information section for specific application rates, timings and the restrictions and limitations 
by crop and use pattern.
Restrictions
xDo not use flood or furrow irrigation to apply, activate or incorporate this product
xDo not use on peat or muck soils or mineral soils with 10% or more organic matter content.
xDo not use on soils classified as sand which have less than 1% organic matter. 
xCrop seeds must be planted a minimum of 1 inch deep.
Ground Application
Use sufficient spray pressure and spray volume for accurate and uniform application. Refer to instructions for the 
spray equipment used to determine the actual minimum volume. The carrier may be either water or a sprayable fluid 
fertilizer. Do not apply this product without dilution in a spray carrier. For preplant, preplant incorporated, or 
preemergence applications, apply VHP58 in a minimum of 10 gallons of water per acre. Ground applications must not 
be made at a height greater than 4 feet above the top of the largest plants if present or the soil surface in 
conventional tillage.

5 
 
Aerial Application
Use Restrictions:
Aerial application is allowed only when environmental condition s prohibit ground application. When this product is 
allowed to be applied by air, applicator must use a minimum fin ished spray volume of 5 gallons per acre. The 
maximum release height must be 10 feet from the top of the cano py, unless a greater application height is required 
for pilot safety.
Do not apply when wind speed favors drift beyond the area intended for treatment.
These 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 ex ceed ¾ the length of the wingspan or rotor.
2. Nozzles must always point backward parallel with the air stre am and never be pointed downwards more 
than 45 degrees. 
3. Observe the regulations of the State where applications are m ade.
4. Applicators must observe and abide by the requirements of th e Aerial Drift Reduction Advisory.
SPRAY DRIFT 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 potentital 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 applicati ons are made improperly or under unfavorable 
environmental conditions. (See Wind, Temperature and Humidity, and Temperature Inversion sections in this label). 
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 used as a preemergent/preplant application. Select medium to very coarse droplet size 
when used postemergence with a contact burndown herbicide. Do not apply as spray droplets smaller than medium 
to coarse (defined by the ASAE standard).
Controlling Spray Droplet Size 
Volume - Use high flow rate nozzles to apply the greatest practical spray volume. Nozzles with higher rated flow 
generall produce larger droplets. 
Pressure - Use the lower spray pressures recommended for the nozzle and do not exceed the manufacturer’s 
recommended pressure. Higher pressure reduces droplet size and does not improve canopy penetration. When 
higher flow rates are needed, use higher flow rate nozzles instead of increasing pressure.
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.
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 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 must 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 applications are made with cross wind, the swath will be displaced downwind. Therefore, 
on the up and downwind edges of the field, the applicator must compensate for this displacement by adjusting the

6 
 
path upwind. Swath adjustment distance must increase with increasing drift potential (higher wind, smaller drops, 
etc).
Wind - Variable wind speeds with changing directions may pose the largest potential for drift damage. Drift potential 
is lowest between wind speeds of 2 to10 mph. However, many factors, including droplet size and equipment type 
determine drift potential at any given speed. Applications must be avoided if wind speed is below 2 mph due to 
variable wind direction and high inversion potential. NOTE: Local terrain can influence wind patterns. Every 
applicator must be familiar with local wind patterns and how they affect spray drift.
Temperature and Humidity - When making applications in low relative humidity set up equipment to produce larger 
droplets to compensate for evaporation, but they still must remain within the medium droplet size category. Droplet 
evaporation is most severe when conditions are both hot and dry.
Temperature Inversions –Applications must not occur during 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 light variable winds common during 
inversions. Temperature inversions are characterized by increasing temperatures with altitude and are common on 
nights with limited cloud cover and light to no wind. They begin to form as the sun sets and often continue into the 
following morning. Their presence can be indicated by ground fog. However, if fog is not present, inversions can also 
be identified 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 inversion, while smoke that moves 
upward and rapidly dissipates indicates good vertical air mixing.
Sensitive Areas – VHP58 must only be applied when the potential for drift to adjacent sensitive areas (e.g. 
residential areas, bodies of water, known habitats for threatened or endangered species and non-target crops) is 
minimal.(e.g. when wind is blowing away from the sensitive areas). Maintain a 10-foot buffer between the application 
area and the closest downwind edge of sensitive terrestrial habitats (such as grasslands, forested areas, shelter 
belts, woodlots, hedgerows, riparian areas, shrublands, and croplands).
Off-Target Movement of VHP58
Drift of dilute spray mixtures containing VHP58 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. VHP58 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 VHP58 drift 
mixtures. Depending on concentration of the spray solution and droplets size (effectively determining the dosage of 
sulfentrazone) and also depending on the inherent sensitivity of the plants involved, these spots or lesions may or 
may not coalesce. These effects will usually not have lasting 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 VHP58 on to unintended crops or plants, 
irrespective of severity, constitutes misapplication of this product. FMC accepts no responsibility or liability for 
potential crop effects that may result from such misapplication of VHP58.
 
CLEANING SPRAY EQUIPMENT 
Many 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 VHP58 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 VHP58 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 ga llons of ammonia (containing at least 3% active) per 
100 gallons of clean water or using a commercial tank cleaner. 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.

7 
 
3. Convenient and thorough cleaning of the sprayer can be achie ved 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 syste m. 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 acco rdance with Federal, State, and local regulations and 
guidelines. 
Do not apply sprayer cleaning solutions or rinsate to sensitive crops. 
Do not store the sprayer for any extended period of time with VHP58 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 an d nozzles with clean water before beginning any 
application. 
Should small quantities of VHP58 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.
When VHP58 has been tank mixed refer to the label of the produc t used previously or tank mixed with VHP58 for 
cleaning instructions.
MIXING AND LOADING INSTRUCTIONS 
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. 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.
Shake well or agitate prior to use.
Mixing Instructions:
1. The spray equipment must be clean before using this product. If it is contaminated with other materials, mixing 
problems and/or clogging can occur and/or crop response can occur.
2. Prepare no more spray mixture than is needed for the immediate application. Applying the product immediately 
after preparation ensures that it is in suspension. If application is delayed, agitation to re-mix the products and 
checking for resuspension ensures proper blending.
3. Maintain maximum agitation throughout the spraying operation. 
4. Flush the spray equipment thoroughly after each use and apply rinsate to an appropriate area.
Mixing Steps:
1. Add 1/4 -1/2 of the required amount of clean water and/or fertilizer to the spray or mixing tank.
2. While maintaining agitation, continue filling the spray tank. When the tank is 3/4 full, add any dry formulation tank 
mix partners and allow them to completely and uniformly disperse.
3. Add the required amount of VHP58 to the spray tank while maintaining agitation. After the product has completely 
and uniformly dispersed into the tank mix, add any other liquid tank mix partners and allow them to completely and 
uniformly disperse.
4. Add the proper amount of spray adjuvant and continue agitation while adding the remaining water and/or fertilizer.
5. Complete filling the tank with clean water and/or fertilizer to maintain sufficient agitation at all times to insure 
surface action until the mixture is uniform. 
6. After use, thoroughly clean the sprayer according to this label (see Cleaning Spray Equipment) and any tank mix 
partner labels.
Mixing VHP58 in Tank Mixtures with Other Products and Fluid Fertilizers
VHP58 is compatible with most commonly used herbicides, insecticides, fungicides, and spray adjuvants. It is the 
pesticide user’s responsibility to ensure that all products are registered for the intended use. Read and follow the

8 
 
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.
VHP58 can be used with liquid fertilizers. It is recommended that a preliminary compatibility jar test be conducted 
using appropriate ratios of VHP58 and fertilizer. Dilution of the fertilizer and/or slurrying of the VHP58 with water may 
aid in the mixing of the fertilizer plus herbicide combination. Prepare no more spray mixture than is needed for the 
immediate application. Applying the product immediately after preparation ensures that it is in suspension. If 
application is delayed, agitation to re-mix the products and checking for resuspension ensures proper blending. 
Compatibility Test 
Before mixing, a jar test is needed to ensure VHP58 compatibility with tank mix partners and adjuvants. The following 
test assumes a spray volume of 25 gallons per acre. For other spray volumes, make appropriate changes in the 
ingredient rates.
1. Add 1.0 pt. of water to each of 2 one-quart jars. Note: Use the same source of water and the other components in 
the compatibility test that will actually be tank mixed and applied. It is important that all components are mixed at a 
temperature similar to the temperature of those used for the actual application.
2. To one of the jars, add 1/4 tsp. or 1.2 milliliters of a compatibility agent approved for this use (1/4 tsp. is equivalent
to 2 pt/100 gallons spray). Shake or stir gently to mix.
3. To both jars, add the appropriate amount of herbicide(s). If more than one herbicide is used, add them separately 
with dry herbicides first, flowables next and emulsifiable concentrates last. Finally, add the appropriate amount of any
adjuvants that will be used. After each addition, shake or stir gently to thoroughly mix. 
(Dry Herbicides and Adjuvants: For each pound to be applied per acre, add 1.4 tsp. to each jar.
Liquid Herbicides and Adjuvants: For each pint to be applied per acre, add 0.5 tsp. or 2.5 milliliters to each jar).
4. After adding all ingredients for the tank mixture, replace and tighten lids. Shake jars by inverting the mixture and 
then let stand for 15 to 30 minutes. 
5. After waiting period, check jars for separation, precipitates, flakes, films on the side, gels or other signs of 
incompatibility. If mixtures separate but can be remixed, the mixture can be sprayed as long as good agitation is 
used. 
6. If the mixtures are incompatible, then try these methods to overcome the problem. A) Make a slurry of dry 
pesticides in water before adding them to the tank B) Add more compatibility agent or increase the water volume of 
the mixture.
7. If tank mixtures are incompatible, then do not spray the mixture. (Properly dispose of testing jars and any pesticide 
waste). 
DRY FERTILIZER APPLICATION
VHP58 may be impregnated or coated onto dry bulk granular fertilizer carriers for fall, preplant surface and preplant 
incorporated applications. Follow all VHP58 label requirements, instructions and precautions. 
All individual state regulations relating to dry granular fertilizer blending, registration, labeling and application are the 
responsibility of the individual and/or company selling the herbicide/ fertilizer mixture.
Select the VHP58 application rate per acre from this label and determine the quantity of dry bulk fertilizer to be 
applied per acre (use a minimum of 200 pounds and a maximum of 750 pounds per acre). Use the equation below to 
determine the amount of VHP58 needed per ton of fertilizer applied.
(Fl oz of VHP58 per acre X 2000) / Pounds fertilizer per acre = oz of VHP58 for 1 ton of fertilizer).
VHP58 may be impregnated on many commonly used dry fertilizer but do not impregnate on ammonium nitrate, 
fertilizers containing ammonium nitrate, potassium nitrate, sodium nitrate or powdered limestone.
To impregnate VHP58 on bulk fertilizer, use a closed rotary drum mixer or other commonly used dry bulk fertilizer 
blender equipped with suitable spray equipment. Mix VHP58 with sufficient water to form a sprayable slurry mixture. 
Spray nozzles be directed to provide uniform fertilizer coverage while avoiding spray contact with mixing equipment. 
Non uniform impregnation can cause crop injury or unsatisfactory performance.
Spray the herbicide mixture onto the fertilizer after blending has started. If necessary, include a suitable drying agent 
to ensure a spreadable herbicide impregnated fertilizer. Apply treated fertilizer immediately after impregnation to 
avoid lump formulation and spreading difficulties. Accurate calibration of fertilizer application equipment and uniform 
fertilizer distribution is essential for satisfactory weed control. Apply the mixture uniformly to the soil with proper 
equipment immediately after blending and moisture is required for activation.
WEEDS CONTROLLED
Use Restrictions:
This product, VHP58, may only be used in accordance with the Product Application Information and the specific crop 
use directions. VHP58 applied fall, early preplant, preplant-incorporated, and preemergence controls the weeds listed 
in Table 1 prior to their emergence. The length of control is dependent on rate applied, amount of rainfall received 
following application and soil type. Please see crop specific use rates for rate requirements based on soil type.

APPLICATION INSTRUCTIONS
Fall Application
VHP58 may be applied in the fall for crops that are to be planted the following spring. For control of emerged weeds 
in the fall use combinations with other burndown herbicides like carfentrazone-ethyl, 2,4-D, dicamba, glyphosate, 
paraquat or glufosinate. It is the pesticide user's responsibili ty 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. Do not exceed 2 inch incorpora tion depth if tilled after application. VHP58 may be 
broadcast surface applied in the fall after crop harvest when soil temperatures at the 4-inch depth are sustained at 
less than 55º F and before the ground freezes to control weeds in minimum or no tillage fields planted the following 
spring. Do not apply to frozen soils or to existing snow cover to prevent VHP58 runoff from rain or snow melt that may 
occur following application.
Preplant, preemergence and early preplant applications
VHP58 may be applied prior to planting up 3 days after planting. Do not apply directly on the crop after the crop 
emerges or if the seedling sprouts are close to the surface. Preplant surface applications are not recommended on 
coarse soils in areas where average annual rainfall (or rainfall + irrigation) typically exceeds 40 inches. If rainfall or 
irrigation is not received within 7 days, weed control may be inconsistent. A light incorporation (less than 2” deep) in 
the soil by mechanical means is allowed and may improve herbicide performance under limited activation moisture 
conditions. Cultivation or a labeled postemergence herbicide ap plication may still be required under certain 
conditions for complete weed control.
If weeds are present at the time of application, use additional weed control methods including tank mixes with an 
appropriate postemergence herbicide(s) to control emerged weeds and follow all label directions, rates, restrictions, 
and precautions on the tank mixture partner labeling. 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.
Preplant incorporated (PPI) applications
For PPI applications of VHP58 incorporate into the upper (1-2 inches) soil surface before planting. Do not incorporate 
greater than 2 inches deep. Use appropriate equipment that provides uniform shallow incorporation, such as a field 
cultivator, harrow, rolling cultivator or finishing disc.
Split applications in labeled crops 
VHP58 can be applied in sequential programs, but do not exceed the maximum use rate per year. Do not make more 
than 2 applications per year.Where weeds are emerged, use appropriate tank mixtures for control of the weed 
species present. 
APPLICATION RATES
Application rates for VHP58 when applied alone, in tank mix, or sequentially are provided in Tables below.

activation and optimum weed control. If no rain occurs within 7 days after application, apply overhead irrigation if 
available, at 0.5 to 1 inch total volume. 
x Excessive rainfall, irrigation, or prolonged wet soil conditions after application of VHP58 from seed germination 
through seedling emergence may increase the risk of dry beans, dry peas seedling injury and must be avoided if 
possible.
x The use of VHP58 may result in temporary growth suppressions or leaf burn on dry beans, dry peas under 
stressful conditions such as inadequate or excessive moisture, cool and hot temperatures, compacted soils, injury 
from other pesticides, disease or other pest damage, mechanical injury, nutrient imbalances, or other conditions 
known to cause plant stress.
x Prolonged periods of dry weather following applications of VHP58 may reduce herbicidal effectiveness. When 
VHP58 is not activated and weeds emerge, a labeled postemergence herbicide will be needed to control weed 
escapes.
x Before applying to dry beans or peas, verification of VHP58 selectivity on your variety must be confirmed to avoid 
injury to sensitive beans varieties. Check with the local Cooperative Extension agent for information on potential 
VHP58 varietal sensitivity. If variety sensitivity is unknown, such as with new varieties, apply VHP58 on a small 
area to confirm variety safety before use on large acreage.

Restrictions for Use in Sunflower (subgroup 20B)
x DO NOT apply more than a maximum cumulative amount of 11.71 fl oz/A VHP 58 (0.389 lb ai/A containing 0.139
lb ai of pyroxasulfone and 0.25 lb ai of sulfentrazone) per year .
x Do not apply more than a cumulative of 0.266 pound active of pyroxasulfone per year from all sequential 
applications. 
x Do not apply more than a cumulative of 0.25 pound active of sulfentrazone per year from all sequential 
applications.
x Do not apply more than 11.71 fl oz/A of VHP58 in a single application.

17 
 
x Do not make more than 2 applications of VHP58 per year when using reduced application rates equal or less than 
5.8 fl oz/A
x The twelve month period is considered to begin upon initial application of the product
x Do not apply within 7 days if a second application is necessary.
Use Instructions and Precautions For Use in Sunflower (subgroup 20B)
x 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. VHP58 use rates must be 
reduced in those areas. If applying VHP58 to coarse textured soils with less than 1.5% organic matter, best 
results are achieved by waiting a minimum of 7-14 days after app lication before planting
x Inadequate seed furrow closure or shallow planting (less than 1.0 inch) may result in undesirable crop response. 
As expected, poor growing conditions including excessive moisture, low temperatures, soil compaction and 
diseases may also cause undesirable crop response.
x Rainfall and/or irrigation totaling at least 0.5 inch prior to weed emergence may be necessary for herbicide 
activation and optimum weed control. If no rain occurs within 7 days after application, apply overhead irrigation if 
available, at 0.5 to 1 inch total volume. 
x Excessive rainfall, irrigation, or prolonged wet soil conditions after application of VHP58 from seed germination 
through seedling emergence may increase the risk of sunflower seedling injury and must be avoided if possible.
x The use of VHP58 may result in temporary growth suppressions or leaf burn on Sunflower under stressful 
conditions including inadequate or excessive moisture, cool and hot temperatures, compacted soils, injury from 
other pesticides, disease or other pest damage, mechanical injury, nutrient imbalances, or other conditions known 
to cause plant stress.
x Prolonged periods of dry weather following applications of VHP58 may reduce herbicidal effectiveness. When 
VHP58 is not activated and weeds emerge, a labeled postemergence herbicide will be needed to control weed 
escapes.
x VHP58 can be used on all types of sunflowers. Before applying to Sunflower subgroup 20B crops verify with your 
local seed company (supplier) the selectivity of VHP58 on your inbred line or hybrid to avoid potential injury.
x Before applying to sunflower, verification of VHP58 selectivity on your variety must be confirmed to avoid injury to 
sensitive sunflower varieties. Check with the local Cooperative Extension agent for information on potential 
VHP58 varietal sensitivity. If variety sensitivity is unknown, such as with new varieties, apply VHP58 on a small 
area to confirm variety safety before use on large acreage.
These Crop Specific Use directions are based upon the interacti ve effects of VHP58 and the primary soil and 
environmental factors, which affect its activity on various wee d species and sensitivity among crops. The user is 
required to observe the instructions and guidance previously pr esented under Application Instructions, VHP58 
Product Use Rates, Rotational Crop Guidelines, Replanting Instr uctions, 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 VHP58 . Consu lt university or extension weed management 
specialists for additional information on specific local variet ies or cultivars and any other pertinent information on 
VHP58 under specific local conditions.
