DIRECTIONS FOR USE
It is a violation of Federal law to use this product in a manner inconsistent with its labeling.
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.
DuPont™ MESOTRIONE 50WG herbicide, also referred to below as MESOTRIONE 50WG or DuPont™
MESOTRIONE 50WG, must
be used in accordance with the directions for use on this label; in separately issued labeling or
exemptions under FIFRA (Supplemental Labels; Special Local Need Registrations; FIFRA Section 18 exemptions) or as otherwise
permitted by FIFRA. Always read the entire label including the Limitation of Warranty and Liability.
INFORMATION
MESOTRIONE 50WG is a systemic preemergence and postemergence herbicide for the selective contact and residual
control of broadleaf weeds in field corn, production seed field corn, field corn grown for silage, yellow popcorn, sweet
corn, and other listed crops. When used preemergence, weeds take up the product through the soil during emergence. Dry
conditions following application may reduce the preemergence activity of MESOTRIONE 50WG. If an activating rain
(0.25 inches) is not received within 7-10 days after a preemergence application, where appropriate, rotary hoeing is
suggested to activate the herbicide. When used postemergence, susceptible weeds take up the herbicide through the treated
foliage and cease growth soon after application. Complete death of the weeds may take up to 2 weeks. The product is
absorbed through the soil and/or by the foliage of emerged weeds.
MESOTRIONE 50WG is not effective for the control of most grass weeds. Preemergence grass herbicides or
postemergence grass herbicides can be tank mixed with MESOTRIONE 50WG to provide broad spectrum weed control in
corn (see appropriate section of label for this information). MESOTRIONE 50WG can be applied postemergence following
a preemergence grass herbicide application. MESOTRIONE 50WG can also be used in combination with a burndown
herbicide, prior to planting, to provide added burndown and residual weed control in field corn, production seed field corn,
field corn grown for silage, yellow popcorn, and sweet corn.
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. Exception: If
the product is soil-injected or soil-incorporated, the Worker Protection Standard, under certain circumstances, allows
workers to enter the treated area if there will be no contact with anything that has been treated.
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.
Shoes plus socks.
Chemical resistant gloves.

ENVIRONMENTAL HAZARDS
Do not apply directly to water, or to areas where surface water is present, or to intertidal areas below the mean high
water mark. Do not contaminate water when disposing of equipment wash water or rinsate.
Surface Water Advisory
This product may contaminate water through drift of spray in wind. This product has a high potential for runoff for several
weeks after application. Poorly draining soils and soils with shallow water tables are more prone to produce runoff that
contains this product. 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 for contamination of water from runoff.
Runoff of this product will be reduced by avoiding applications when rainfall is forecasted to occur within 48 hours. Sound
erosion control practices will reduce this product's contribution to surface water contamination.
USER SAFETY RECOMMENDATIONS
USERS SHOULD: Wash hands before eating, drinking, chewing gum, using tobacco, or using the toilet. Remove
PPE immediately after handling this product. Wash the outside of gloves before removing. As soon as possible, wash
thoroughly and change into clean clothing. Remove clothing/PPE immediately if pesticide gets inside. Then wash
thoroughly and put on clean clothing.

RESISTANCE MANAGEMENT
MESOTRIONE 50WG is a Group 27 Herbicide (contains the active ingredient mesotrione).
Naturally occurring biotypes of certain broadleaf weed species with resistance to triazines, glyphosate, PPO, HPPD and
ALS inhibiting herbicides are known to exist. Performance of MESOTRIONE 50WG is not affected by the presence of
biotypes resistant to triazines, glyphosate, PPO or ALS inhibiting herbicides.
To help prevent the development of resistance to MESOTRIONE 50WG in corn, always use labeled rates. If applying
MESOTRIONE 50WG postemergence after a preemergence application of an HPPD inhibiting herbicide, always add
atrazine as a tank mix partner, or use a herbicide with an alternate mode of action that is active on the target species in areas
where the use of triazines is not appropriate. Apply no more than 0.24 lb. of mesotrione active ingredient per acre of corn
per year (equivalent of 7.7 oz. per acre per year of DuPont™ MESOTRIONE 50WG). If additional herbicide must be
applied, it is recommended that a different mode of action be used, i.e., other than an HPPD inhibitor (Group 27 Herbicide).
Apply MESOTRIONE 50WG at full label rates to help prevent selection for, or population shifts toward, marginally
tolerant weed species and/or species biotypes.
INTEGRATED PEST MANAGEMENT
MESOTRIONE 50WG should be integrated into an overall weed and pest management strategy whenever the use of a
herbicide is required. Practices known to reduce weed development (tillage, crop competition) and herbicide use (weed
scouting, proper application timing, banding) should be followed wherever possible. Consult local agricultural and weed
authorities for additional IPM strategies established for your area.

Table 2. Weeds Controlled With Preemergence Applications of DuPont™ MESOTRIONE 50WG
C = Control PC = Partial Control

ROTATIONAL CROPS
Immediate: Corn (all types), asparagus, cranberry, flax, millet (pearl), grasses grown for seed (Kentucky bluegrass, perennial
and annual ryegrass, and tall fescue), oats, rhubarb, sorghum (grain and sweet), and sugarcane may be replanted immediately.
4 Months: Small grain cereals, including wheat, barley and rye.
10 Months: Alfalfa, blueberry, canola, cotton, currant, lingonberry, okra, peanuts, peas1,2, potatoes, rice, snap beans1,2,
soybeans, sunflowers, sweet potatoes, and tobacco. 
18 Months: Sugar beets, dry beans, cucurbits, red clover, and all other rotational crops may be replanted 18 months after
application of MESOTRIONE 50WG. Planting unspecified rotational crops, or those rotational crops that are specified at
shorter than specified intervals may result in injury to the rotational crop.
1 Plant these rotational crops only if the following criteria below have been met. If all criteria are not met, plant peas and snap
beans a minimum of 18 months following mesotrione application.
- A minimum of 20" of rainfall plus irrigation has been received between application and planting of the rotational crop.
- Soil pH is 6.0 or greater.
- Application of Mesotrione at 3 oz product/A or less applied no later than June 30 the year preceding rotational crop planting.
- No other HPPD herbicides were applied the year prior to planting peas and snap beans.
2 Do not plant peas or snap beans on sand, sandy loam or loamy sands in Minnesota or Wisconsin.
RESTRICTIONS
Do not apply MESOTRIONE 50WG to white popcorn or ornamental (Indian) corn.
Do not cultivate corn within 7 days before or after a MESOTRIONE 50WG application as weed control from the
MESOTRIONE 50WG application may be reduced.
Do not apply this product through any type of irrigation system.
Do not apply with suspension fertilizers as the carrier, unless specifically address under one of the tank mixes sections of this
label or other product labels containing MESOTRIONE 50WG, or injury may occur.
Do not apply MESOTRIONE 50WG postemergence in a tank mix with emulsifiable concentrate grass herbicides, unless
specifically addressed under one of the tank mix sections of this label, or injury may occur.
Do not use aerial application to apply MESOTRIONE 50WG unless specified otherwise under the specific crop section on the
label.
PRECAUTIONS
Avoid drift onto adjacent crops.
Severe corn injury may occur if MESOTRIONE 50WG is applied postemergence to corn crops that were treated with
“Counter” or “Lorsban”, which may result in corn crop yield loss.
Severe corn injury may occur if MESOTRIONE 50WG is applied foliar postemergence in a tank mix with any
organophosphate or carbamate insecticide which may result in corn crop yield loss.
Severe corn injury may occur if any organophosphate or carbamate insecticide is applied foliar postemergence within 7 days
before or 7 days after MESOTRIONE 50WG application, which may result in corn crop yield loss.
When weeds are stressed due to drought, heat, lack of fertility, flooding, or prolonged cool temperatures, control can be
reduced or delayed since the weeds are not actively growing. Weed escapes or regrowth may occur when application is made
under prolonged stress conditions. Optimum weed control will be obtained if an application of MESOTRIONE 50WG is made
following label directions when weeds are actively growing.
MESOTRIONE 50WG may be applied with pyrethroid type insecticides like “Asana” or “Warrior” or with diamide type
insecticides such as DuPont™ PREVATHON®.
SPRAY DRIFT
RESTRICTION: For aerial application use only nozzles producing coarse-ultra coarse droplets. Do not use nozzles producing
fine-medium size droplets.
Do not apply when weather conditions may cause drift to nontarget areas. Drift may result in injury to adjacent crops and
vegetation. To avoid spray drift, DO NOT apply when wind speed is greater than 10 mph or during periods of temperature
inversions. Use of larger droplet sizes will also reduce spray drift.
AVOIDING SPRAY DRIFT AT THE APPLICATION SITE IS THE RESPONSIBILITY OF THE APPLICATOR.
The interaction of equipment and weather related factors determine the potential for spray drift. The applicator is responsible
for considering all these factors when making a decision.
6

Information on Droplet Size
The most effective way to reduce spray drift potential is to apply large droplets. The best drift management strategy is to apply
the largest droplets that provide sufficient coverage and control. Applying larger droplets reduces drift potential, but will not
prevent drift if applications are made improperly or under unfavorable environmental conditions. 
Controlling Droplet Size
• Volume – Use high flow rate nozzles to apply the highest practical spray volume. Nozzles with higher rated flows produce
larger droplets.
• Pressure – Do not exceed the nozzle manufacturer’s recommended pressures. For many nozzle types, lower pressure
produces larger droplets. When higher flow rates are needed, use higher rate nozzles instead of increasing pressure.
• Number of Nozzles – Use the minimum number of nozzles that provide uniform coverage.
Sensitive Areas
The pesticide must only be applied when the potential for drift to adjacent sensitive areas, (e.g., residential areas, bodies of
water, known habitat for threatened or endangered species, nontarget crops) is minimal (e.g. when wind is blowing away from
the sensitive areas).
ADDITIONAL SPRAY DRIFT PRECAUTIONS FOR AERIAL APPLICATIONS
The distance of the outer-most nozzles on the boom must not exceed ¾ the length of the wingspan or rotor. Nozzles must
always point backward parallel with the air stream and never be pointed downwards more than 45 degrees. Where states have
more stringent regulations, they must be observed. Spray must be released at the lowest height consistent with effective weed
control and flight safety. For best results, quantifiably pattern test each specific aerial application vehicle used for aerial
application of Mesotrione 50WG initially and every year thereafter. 
RESTRICTION: For aerial application use only nozzles producing coarse-ultra coarse droplets. Do not use nozzles producing
fine-medium size droplets. 
For some 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. Do not make applications at a height greater than 10 feet above the top of the largest plants
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. When applications are made with a crosswind, 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
path of the aircraft upwind. Increase swath adjustment distance with increasing drift potential (higher wind, smaller drops,
etc.). Drift potential is lowest between wind speeds of 2-10 mph. However, many factors, including droplet size and equipment
type determine drift potential at any given speed. Whenever possible, avoid application below 2 mph due to variable wind
direction and high inversion potential. Note: Local terrain can influence wind patterns. Ensure that every applicator is familiar
with local wind patterns and how they affect drift. When making applications in low relative humidity, set up equipment to
produce larger droplets to compensate for evaporation. Droplet evaporation is most severe when conditions are both hot and
dry. Whenever possible avoid application 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 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 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 connected cloud (under low wind conditions) indicates an
inversion, while smoke that moves upwards and rapidly dissipates indicates good vertical air mixing. The pesticide must only
be applied when the potential for drift to adjacent sensitive areas (e.g., residential areas, bodies of water, known habitat for
threatened or endangered species, non-target crops) is minimal (e.g. when wind is blowing away from the sensitive areas). 
APPLICATION PROCEDURES 
POSTEMERGENCE GROUND APPLICATION
For best results, apply DuPont™ MESOTRIONE 50WG to actively growing weeds. For a list of weeds controlled see Table 1.
Susceptible weeds which emerge soon after application of MESOTRIONE 50WG may be controlled after they absorb the
herbicide from the soil. MESOTRIONE 50WG will not control most grass weeds.
Postemergence Ground Spray Equipment
Ensure that spray nozzles are uniformly spaced, the same size and type, and provide accurate and uniform application. Use
spray nozzles that provide medium to coarse droplet size to provide good coverage and avoid drift. Good weed coverage is
essential for optimum weed control. Boom height for broadcast over-the-top applications must be based on the height of the
crop – at least 15 inches above the crop canopy.
7

Apply in a spray volume of 10-30 gals./A. Use a pump that can maintain a pressure of at least 35-40 psi at the nozzles and
provide proper agitation within the tank to keep the product dispersed. Lower pressures may be used with extended range or
drift reduction nozzles. When weed foliage is dense, use a minimum of 20 gals.
Flat fan nozzles of 80° or 110° are recommended for optimum postemergence coverage. Do not use floodjet nozzles or
controlled droplet application equipment for postemergence applications.
Nozzles may be angled forward 45° to enhance penetration of the crop and provide better coverage. Ensure that all in line
strainer and nozzle screens in the sprayer are 50-mesh or coarser.
Always ensure that agitation is maintained until spraying is completed, even if stopped for brief periods of time. If the agitation
is stopped for more than 5 minutes, resuspend the spray solution by running on full agitation prior to spraying.
Postemergence Adjuvants
When an adjuvant is to be used with this product, the use of an adjuvant that meets the standards of the Chemical Producers
and Distributors Association (CPDA) adjuvant certification program is recommended.
The following adjuvant recommendations are intended primarily for MESOTRIONE 50WG use in corn. Refer to the use
directions section of each crop section for specific adjuvant recommendations
For postemergence applications made after the crop has emerged, add crop oil concentrate (COC) to the spray solution at rate
of 1.0 gal./100 gals. of water (1.0% v/v) or add a high surfactant oil concentrate (HSOC) to the spray solution at a rate of 2
qt/100 gallons of water. The use of a nonionic surfactant (NIS) at 1 qt./100 gallons of water (0.25% v/v) instead of a COC or
HSOC is allowed, but the weed control achieved with COC or HSOC is consistently better than NIS. The use of methylated
seed oil (MSO) adjuvants or MSO blend adjuvants for postemergence applications of MESOTRIONE 50WG may cause
severe crop injury to occur. MSO adjuvants are not recommended unless directed for a specific tank mix under the
MESOTRIONE 50WG COMBINATIONS – POSTEMERGENCE section of this label, or other product labels
containing MESOTRIONE 50WG or unless permitted by a supplemental MESOTRIONE 50WG label. In addition to
COC or HSOC, always add spray grade UAN (e.g., 28-0-0) to the spray solution at a rate of 2.5% (v/v) or AMS at 8.5 lbs./100
gals. of spray solution, except if precluded elsewhere on this label or unless by a supplemental MESOTRIONE 50WG label.
Do not add UAN or AMS when making postemergence applications of MESOTRIONE 50WG to yellow popcorn or sweet
corn, or severe crop injury may occur.
For postemergence applications to yellow popcorn and sweet corn, the use of a nonionic surfactant (NIS) instead of a crop oil
concentrate (COC) is recommended, so as to minimize the risk of crop injury. A COC may be used, and will increase the level
of weed control achieved, especially under dry growing conditions, but the risk of crop injury is increased significantly under
lush growing conditions. Because the adjuvant benefits of UAN or AMS are not available in yellow popcorn or sweet corn,
weeds less than five inches should be targeted, and the addition of atrazine is recommended wherever rotational or local
atrazine restrictions will allow, in order to achieve the level of weed control that is listed for MESOTRIONE 50WG plus COC
plus UAN or AMS (third column) in Table 1.
PREEMERGENCE GROUND APPLICATION
For a list of weeds controlled preemergence, refer to Table 2.
Preemergence Ground Spray Equipment
Spray nozzles should be uniformly spaced, the same size and type, and should provide accurate and uniform application. Use
spray nozzles that provide medium to coarse droplet size to provide good coverage and avoid drift. Apply in a spray volume of
10-80 gals./A using water or liquid fertilizer (excluding suspension fertilizers) as the carrier. Use a pump that can maintain a
pressure of at least 35-40 psi at the nozzles and provide proper agitation within the tank to keep the product dispersed. Lower
pressures may be used with extended range or drift reduction nozzles.
Always ensure that agitation is maintained until spraying is completed, even if stopped for brief periods of time. If the agitation
is stopped for more than 5 minutes, resuspend the spray solution by running on full agitation prior to spraying.
Preemergence Adjuvants
For DuPont™ MESOTRIONE 50WG preplant or preemergence applications, and where weeds are present, the use of any
adjuvant for agricultural use is permitted. In these situations, MSO type adjuvants are typically better than COC type adjuvants,
which are typically better than NIS type adjuvants for enhancing weed control. UAN or AMS can be added and typically
provides better weed control than not adding one of these. If MESOTRIONE 50WG is being tank mixed with another
registered herbicide in this situation, refer to the tank mix partner label for adjuvant precautions and restrictions.
AERIAL APPLICATION 
Restriction: Mesotrione 50WG can be applied aerially only to corn.
Restriction : For aerial application use only nozzles producing coarse-ultra coarse droplets. Do not use nozzles producing fine-
medium size droplets.
Applications must be made in a minimum of 2 gallons of water per acre.

SPRAY EQUIPMENT
Cleaning Equipment After MESOTRIONE 50WG Application
Special attention must be given to cleaning equipment before spraying a crop other than corn. Mix only as much spray solution
as needed.
1. Flush tank, hoses, boom, and nozzles with clean water.
2. Prepare a cleaning solution of 1 gal. of household ammonia per 25 gals. of water. Many commercial spray tank cleaners
may be used.
3. Use a pressure washer to clean the inside of the spray tank with this solution. Take care to wash all parts of the tank,
including the inside top surface. If a pressure washer is not available, completely fill the sprayer with the cleaning solution
to ensure contact of the cleaning solution with all internal surfaces of the tank and plumbing. Start agitation in the sprayer
and thoroughly recirculate the cleaning solution for at least 15 minutes. All visible deposits must be removed from the
spraying system.
4. Flush hoses, spray lines, and nozzles for at least 1 minute with the cleaning solution.
5. Dispose of rinsate from steps 1-3 in an appropriate manner.
6. Repeat steps 2-5.
7. Remove nozzles, screens, and strainers and clean separately in the ammonia solution after completing the above
procedures.
8. Rinse the complete spraying system with clean water.
MIXING PROCEDURES
Refer to the Crop Use Directions section of this label for recommended tank mixes.
Always refer to labels of other pesticide products for mixing directions and precautions which may differ from those outlined
here. Use in accordance with the most restrictive of label limitations and precautions. No label dosage rates must be exceeded.
This product cannot be mixed with any product containing a label prohibition against such mixing. Do not tank mix
MESOTRIONE 50WG with any other insecticide, fungicide, fertilizer solution, or adjuvant not recommended on the label
without testing compatibility, as poor mixing may result. It is recommended that the compatibility of any tank mix combination
be tested on a small scale such as a jar test before actual tank mixing.
Follow the mixing instructions for adding MESOTRIONE 50WG to the spray tank:
1. Only use sprayers in good running condition with good agitation. Ensure the sprayer is cleaned according to instructions on
label of the product used prior to MESOTRIONE 50WG. For postemergence applications, use only clean water for the
spray solution. Ensure that all in line strainer and nozzle screens in the sprayer are 50-mesh or coarser. Avoid using screens
finer than 50-mesh.
2. Liquid fertilizer (excluding suspension fertilizers) may be used as the carrier for preemergence applications.
3. Begin to fill sprayer tank or premix tank with clean water and engage agitator. Agitation must be continued throughout the
entire mixing and spraying procedure.
4. When the sprayer or premix tank is half full of water, add AMS and agitate until completely dispersed.
5. Next add MESOTRIONE 50WG slowly and agitate until completely dissolved. Wait at least 1 minute after the last of the
MESOTRIONE 50WG has been added to the tank to allow for complete dispersion. A longer agitation period may be
required to disperse MESOTRIONE 50WG when using cold water from sources such as deep drilled wells.
6. If tank mixing, add the tank mix product next.
7. Finally, add adjuvant and UAN, if needed, and then continue to fill tank to desired level with water.
CORN CROP USE DIRECTIONS
MESOTRIONE 50WG may be applied by ground for preemergence or postemergence weed control in field corn, production
seed field corn, field corn grown for silage, yellow popcorn, and sweet corn. Mesotrione 50WG may also be applied aerially
for preemergence or postemergence weed control only in the following states: Alabama, Arkansas, Colorado, Florida, Georgia,
Illinois, Indiana, Iowa, Kansas, Kentucky, Louisiana, Minnesota, Mississippi, Missouri, Nebraska, North Dakota, Ohio,
Oklahoma, South Dakota, Tennessee, and Texas. Refer to seed company recommendations for use on field corn inbred lines.
Special adjuvant restrictions must be followed for postemergence applications of MESOTRIONE 50WG in yellow popcorn or
sweet corn (see the Postemergence Adjuvant section of this label). Do not apply DuPont™ MESOTRIONE 50WG to white
popcorn or ornamental (Indian) corn.
Postemergence applications (after crop emergence) of MESOTRIONE 50WG may cause crop bleaching in some yellow
popcorn and sweet corn hybrids. Crop bleaching is typically transitory and has no affect on final yield or quality. However,
herbicide sensitivity in yellow popcorn and sweet corn varies widely, and all yellow popcorn and sweet corn hybrids have not
been tested. Contact your popcorn or sweet corn company, Fieldman, or University Specialist about hybrid recommendations
9

before making a postemergence application of MESOTRIONE 50WG to yellow popcorn or sweet corn. Do not include
nitrogen based adjuvants (UAN or AMS) when making postemergence applications of MESOTRIONE 50WG to yellow
popcorn or sweet corn.
Temporary crop response (transient bleaching) from postemergence applications to field corn may occur under extreme
weather conditions or when the crop is suffering from stress. Field corn quickly outgrows these effects and develops normally.
Apply MESOTRIONE 50WG for the control of broadleaf and grass weeds listed in Tables 1 and 2. 
Corn may be treated up to 30 inches tall or up to the 8-leaf stage of corn growth. 
Restrictions:
Do not apply more than a total of 7.7 oz. (0.24 lb. mesotrione active ingredient) of MESOTRIONE 50WG per acre per year.
Do not make more than 2 applications of MESOTRIONE 50WG per year.
Do not exceed 6.0 oz. (0.188 lb. a.i./A) in a single postemergence application. 
Do not make the second application of MESOTRIONE 50WG within 14 days of the first application.
Do not feed or harvest forage, grain, or stover within 45 days after application.
MESOTRIONE 50WG USED ALONE – POSTEMERGENCE
Apply MESOTRIONE 50WG alone at 2.5-6.0 oz./A per application. Use the higher rate for extended residual weed control.
Always add an appropriate adjuvant to the spray tank (see the Postemergence Adjuvant section under APPLICATION
PROCEDURES of this label).
For best results, apply MESOTRIONE 50WG to actively growing weeds. For a list of weeds controlled see Table 1.
Susceptible weeds which emerge soon after application of MESOTRIONE 50WG may be controlled after they absorb the
herbicide from the soil. MESOTRIONE 50WG will not control most grass weeds.
Two postemergence applications of MESOTRIONE 50WG may be made with the following restrictions:
• Only one postemergence application may be made if Mesotrione 50WG has been applied preemergence. Do not exceed a
total of two applications per year. 
• Do not exceed a total of 7.7 oz./A (0.24 lb. a.i./A) of MESOTRIONE 50WG per year.
• Do not make the second application within 14 days of the first application.
• Application of MESOTRIONE 50WG at rates less than 3.0 oz./A (0.094 lb. a.i./A) postemergence may result in incomplete
weed control and loss of residual control.
• Do not exceed a total of 6.0 oz./A (0.19 lb. a.i./A) for all postemergence applications.
• If MESOTRIONE 50WG is applied postemergence to ground that received a preemergence application of an HPPD
inhibiting herbicide, atrazine must be tank mixed with MESOTRIONE 50WG, or use a herbicide with an alternate mode of
action that is active on the target species in areas where the use of triazines is not appropriate
• If atrazine is mixed with MESOTRIONE 50WG, do not apply to corn that is more than 12 inches in height.
• Corn may be treated up to 30 inches tall or up to the 8-leaf stage of corn growth. Do not harvest forage, grain, or stover
within 45 days after application.
MESOTRIONE 50WG USED ALONE – PREEMERGENCE
