IMPORTANT 
Failure to observe the APPLICATION PRECAUTIONS section of this 
label may result in injury to desirable vegetation. 
• Desirable plants including some species of trees, shrubs, flowers, 
agronomic crops, and truits and vegetables are sensitive to Com­
mence ® EC herbicide. 
• Foliar contact with spray drift or vapors may cause whitening or yellow­
ing of sensitive plants. Symptoms are generally temporary in nature but 
may persist on some plants. 
• Carryover injury to approved rotational crops may result under 
extremely dry conditions. Choice of rotational crop hybrid, soil factors, 
and choice of other crop protection chemicals can Impact the risk of 
injury to approved rotational crops. Refer to Rotational Cropping 
Precautions. 
SPRAYER CLEANUP 
Do not drain or flush equipment on or near desirable trees or other plants, 
or in areas where their roots may extend or in locations where the chemical 
may be washed or moved into contact with their roots. Do not contaminate 
any body of water including irrigation water that may be used on other 
crops. Carefully follow sprayer clean-up instructions noted below to prevent 
spray tank residues from damaging other crops. 
Sprayer equipment should be thoroughly cleaned to remove all traces of 
herbicide that might injure other subsequently sprayed crops. The steps 
below are suggested for the thorough cleaning of spray equipment follow­
ing appllcations of Commence EC herbicide or tank mixes of Commence 
EC with other labeled products. 
1) Drain any remaining spray solution from tank and discard in an 
approved manner (See Note below). 
2) Thoroughly wash down the inside as well as outside surfaces of 
equipment while filling the spray tank half full of water. Recycle water 
solution through the equipment for five minutes and dispose of in an 
approved manner (see Note below). 
3) Fill tank with water while adding 1 quart of bleach and 1 pint of 
detergent for every 25 gallons of water. Operate the pump to circulate 
the solution through the sprayer system for 15 to 20 minutes and 
discharge a small amount of the solution through the boom and 
nozzles. let the solution stand for several hours, preferably overnight. 
4) Start spray system up, recirculate for 15 minutes, then flush the solution 
out of spray tank through the boom. 
• When switching from water dilutions to applications utilizing crop oil 
or liquid fertilizer as a carrier, a small volume of crop oil or liquid 
fertilizer should be flushed through the lank, pump, hoses, and 
boom prior 10 the next use. Dispose of crop oil or liquid fertilizer 
rinsate in an approved manner (see Note for local, state and Fed­
eral guidelines). 
5) Remove the nozzles, screens, and line filter and wash in a pail of warm, 
soapy water. 
6) Flush the system with two tankfuls of water. 
NOTE: Dispose of excess spray mixture andlor rinsates by application and 
incorporation to cropland as described on this label. If excess spray 
mixture andlor rinsates cannot be disposed of according to label instruc­
tions, contact your State Pesticide or Environmental Control Agency or the 
Hazardous Waste representative at Ihe nearest EPA regional office for 
guidance. 
GENERAL MIXING CONDITIONS 
Commence EC Alone: Start with a clean spray tank. Fill sprayer 1.13 to % 
full with clean water or liquid fertilizer. Start agitation. Add correct quantity 
of Commence EC, continue agitation and finish filling the tank. 
Tank Mixtures: Vigorous, continuous agitation is required for all tank 
mixes. Sparger pipe agitators generally provide the best agitation in 
spray tanks. To prevent foaming, avoid stirring or splashing air into the 
mixture during fitling by placing the end of the fill pipe below the surface of 
the water in the spray tank. Do not allow the mixture to siphon back into 
the water source. 
3 
Mixing Order: FiJI the tank Y4 to % full with clean water or liquid fertilizer. 
(See next page for additional liquid fertilizer mixing instructions.) Start the 
agitation. Add in the following order: dry flowables (DF) wettable powders 
(WP), aqueous suspensions (AS), flowables (F), and liquids (L) to the 
water and agitate until the product(s) are completely dispersed. Allow 
additional mixing and dispersion time when using dry flowable products. 
Continue agitation and fill tank to 3/4 full, add the Commence EC mix 
thoroughly. Maintain agitation during filling and through application. If 
spraying and agitation must be stopped before the tank is empty the 
materials may settle to the bottom. In this case it is important to resuspend 
all of the material in the bottom of the tank before continuing the spray 
application. A sparger agitator is particularly useful for this purpose. 
Sometimes it is more difficult to resuspend settled material than it is to 
suspend originally. 
Read and carefully follow aU label instructions for each material added to 
the tank. Premixing dry and flowable formulations with water (slurrying) 
and pouring the slurry through a 20 or 35 mesh wetting screen in the top of 
the tank will help assure good initial dispersion in the tank water. Line 
screens in the tank should be no finer than 50 mesh (100 mesh is finer 
than 50 mesh). 
If a buildup of material on the walls of the spray tank is observed, wash the 
tank with soapy water between fillings. Rinse and continue the spraying 
operation. Clean the tank, lines, and screens thoroughly after use. 
As the spray volume per acre decreases the importance of accurate 
calibration and uniform application increases. Check the sprayer daily to 
ensure proper calibration and uniform application. Do not apply Com­
mence EC when the wind can cause drifting of spray particles which can 
result in non-uniform application. When using drift reducing agents, follow 
specific product label instructions for order of addition to spray tank. 
Liquid Fertilizer Mixing Directions: Emulsifiable concentrates, such as 
Commence EC, can be mixed with liquid fertilizers. In aU cases, continuous 
agitation is required to prevent the Commence EC from rising to the 
surface as an oily layer. When necessary (see Liquid Fertiiizer 
Compatibility Test below), a compatibility agent can be used to ensure that 
the Commence EC emulsifies properly (I.e., has a milky appearance rather 
than an oily layer). The use of compatibility agents is especially important 
when tank mixing emulsifiable concentrates (EC) with dry flowables (OF) 
wettable powders (WP) flowables (F) liquids (L), aqueous suspensions 
(AS), or solutions (S) in liquid fertilizer. If the emulsion is not properly 
formed, and the EC rises to the surlace of the fertilizer as an oil ("olls ouf'), 
the oil may combine with the wettable powder, flowable, or suspension to 
form oily curds (viscous phase) whIch are difficult to disperse. 
Anyone of the compatibility agents listed below is helpful in causing 
emulsifiable concentrates to form non-oiling mixtures with liquid fertilizers. 
These compaUbility agents can be used at rates as low as one and one­
half (1 Y2) to two (2) pints per ton of liquid fertilizer and should be mixed 
well with the fertilizer before adding the emulsifiable concentrate. 
Read the label on the compatibility agent and follow the directions.

Each of the above is a phosphate ester type surfactant designed to be 
used with liquid fertilizers. They usually do not work well as compatibility 
agents in tank mixtures in water. 
Testing for Tank Mix Compatibility in Liquid Fertilizers: Emulsifiable 
concentrates alone or in tank mixture with dry flowables (OF), wettable 
powders (WP), liquids (L), flowabies (F). aqueous suspensions (AS), or 
solutions (S), may not combine properly with some fluid fertilizer materials. 
Small quantities should always be tested before full-scale mixing. This will 
determine whether a compatibility agent is needed and which agent does 
the best job. The compatibility agents listed above have been thoroughly 
tested. There are many other surlactants on the market which were not 
designed for use with liquid fertilizers. 
Use the following test to select the correct agent for your mixture: 
1. Put one (1) pint of the liquid fertilizer in a quart jar. 
2. Add one (1) to four (4) teaspoonful(s) of the OF, WP, L, F, or AS 
formulation (depending on the recommended rate per acre) to the liquid 
fertilizer. Close jar and agitate u1til dispersed evenly in the fertilizer. 
If the materials do not disperse weU, it may be necessary to slurry the 
chemicals in water before adding to the fertilizer.

3. After dispersing the materials (Step 2), add three (3) to four (4) 
teaspoonfuis of the Commence® EC to the jar and shake well. Add 
solution herbicides to the mixture last and agitate. Observe the jar tor 
about 10 minutes. If the materials rise to the surtace and form a thick 
layer (oily curds), which will not disperse when agitated, a compatibil­
ity agent is needed. If the mixture is easily dispersed to its original 
state with slight agitation, no agent is needed, but good agitation must 
be provided in the fertilizer spray tank. 
4. If the need tor a compatibility agent is shown in Step 3, using a clean 
quart jar, start at Step 1 above, add one-half (Y2) teaspoonful of the 
compatibility agent to the liquid fertilizer, mix well, then repeat Steps 
2 and 3. 
An effective compatibility agent will cause the mixture to remain uniformly 
mixed with little or no separating or oil rising to the surtace for one-haH 
(Yz) hour or longer. If slight separation does occur, two (2) or three (3) 
inversions of the jar should give a uniform remix. If oil curds form which 
will not disperse, more agent or another agent should be tried. 
Use a clean jar for each test. The compatible mixture will have a uniform 
appearance and will be relatively easy to keep mixed with gentle agitation 
of the jar.

COMMENCE EC SPRAY DRIFT PRECAUTIONS 
Non-target spray drift of Commence EC hl~rbicide should be avoided to 
prevent whitening of desirable vegetation. Drift is influenced by many 
factors which include wind speed, spray pressure, particle size, nozzle 
type, and boom height. 
Do not apply when weather conditions favor drift. If wind speeds 
exceed 10 miles per hour, a drift reducing additive must be used. 
A minimum spray volume of 10 gallons per acre is recommended with 
appropriate nozzle types and sizes that produce coarser sprays. 
The use of agriculturally approved drift reducing additives is recom­
mended for application volumes of 15 to 40 gallons per acre when 
spraying in the proximity of desirable plants (see list above). 
The use of an agriculturally approved dri"1 reducing additive is required 
at finished spray volumes of 10 to 15 gal!ons per acre. 
Use minimum spray pressure and boom height maintaining uniform 
spray pattern. 
Do not exceed 40 psi spray pressure. 
Selection and proper use of spray equipment is critical in minimizing 
spray drift. The following table suggests pressures, flow rates, and 
nozzle sizes for drift reduction using various nozzle types.

The interaction of many equipment and weather-related factors 
determines the potential for spray drift. The applicator is responsible for 
considering all these factors when making application decisions. 
AVOIDING SPRAY DRIFT IS THE RESPONSIBILITY OF THE 
APPLICATOR. 
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 and control. APPLYING LARGER 
DROPLETS REDUCES DRIFT POTENTIAL BUT WILL NOT PREVENT 
DRIFT IF APPLICATIONS ARE MADE IMPROPERLY OR UNDER 
UNFAVORABLE ENVIRONMENTAL CONDITIONS' See Wind, 
Temperature and Humidity, and Temperature Inversions sections on 
this label.

Controlling Droplet Size· General Techniques 
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 manufacturer's recommended spray 
pressures. For many nozzle types lower pressure produces larger 
droplets. WHEN HIGHER FLOW RATES ARE NEEDED, USE A 
HIGHER-CAPACITY NOZZLE INSTEAD OF INCREASING 
PRESSURE. 
Number of Nozzles· Use the minimum number of nozzles that 
provide uniform coverage. 
Nozzle Orientation - Orienting nozzles so that the spray is released 
parallel to the airstream produces larger droplets than orientintations 
and is the recommended practice. Significant deflection from 
horizontal will reduce droplet size and increase drfit 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. Solid stream nozzles 
orinted straight back produce the largest droplets and the lowest drift. 
BOOM LENGTH 
For some use patterns, reducing the effective boom len9ht to less 
than3/4 of the wingspan or rotor length may further reduce drift without 
reducing swath width. 
BOOM HEIGHT 
Setting the boom at the lowest labeled height (if specified) which provides 
uniform coverage reduces the exposure of droplets to evaporation and 
wind. For ground equipment. the boom should remain level with the crop 
and have minimal bounce. 
APPLICATION HEIGHT 
Application should not be made 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. 
SWATH ADJUSTMENT 
When applications are made with a crosswind, the swath will be 
displaced downward. 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. Swath adjustment distance should 
increase, with increasing drift potential (higher wind. smaller drop, etc.). 
familiar with local wind patterns and how they affect spray drift. 
WIND 
Drift Potential is lowest between wind sppeds of 2-10 mph. However, 
many factors, including droplet size and equipment type determine drift 
potential at any given spped. Application should be avoided below 2 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 affect spray drift. 
TEMPERATURE AND HUMIDITY 
When making applications in hot and dry conditions, set up equipment to 
produce larger droplets to reduce effects of evaporation. Droplet 
evaporation is most severe when conditions are both hot and dry. 
TEMPERATURE INVERSIONS 
Drift potential is high during a temperature inversion. Temperature 
inversions restrict vertical air mixing, which causes small suspended 
droplets to remain close to the ground and move laterally in a 
concentrated cloud. Temperature inversions are characterized by 
increasing temperature with attitude 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 
concentrated cloud (under low wind conditions) indicates an inversion, 
while smoke that moves upward and rapidly dissipates indicates good 
vertical air mixing.

SENSITIVE AREAS 
This pesticide should only be applied when the potential for drift to 
adjacent sensitivie 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. 
ROTATIONAL CROPPING PRECAUTIONS: Under some 
COnditions, temporary whitening or yellowing of leaves may occur on 
approved rotational crops where undesirable soil residues of 
Commence EC exist. 
Under abnormal conditions, carryover injury to rotational crops can 
occur. The following factors can contribute to increased risk of injury to 
rotational crops: 
1) Exceeding label recommended rates. 
2) OVerapplication resulting from use of worn nozzles excessive over­
lapping of spray swaths, failing to shut off spray booms when turning 
(end row areas), or slowing or stopping sprayer. 
3) Soil with pH less than or equal to 5.9. 
4) Extreme dryness in the four months following application. 
5) Use of organophosphate soil insecticides followed by use of some 
postemergence corn herbicides. 
6) Choice of rotational crop hybrid. 
Additional recommendations to prevent rotational crop injury may be 
provided in the form of selVice bulletins for locations where risk of injury 
is significantly increased due to extremely dry conditions.

cillc crop. for additional crop planting information. 
GENERAL USE PRECAUTIONS 
APPLICATION AND ENVIRONMENTAL CONOITIONS: 
Applied according to directions and under normal growing conditions. 
Commence EC will not harm the treated crop. OverappHcation may 
resutt in crop injury or a soil resIdue. Uneven application or improper 
soil incorporation of Commence EC can result in erratic weed control or 
crop Injury. Seedling disease. cold weather, deep planting, excessive 
mOisture, high salt ooncentration or drought may weaken crop seedlings 
and increase the possibility of damage from Commence EC. Under 
these conditions. delayed crop development or reduced yields may 
result. Application to soils with pH of 6.0 or lower may result in 
undesirable soil residues and greater potential for injury to rotational 
crops. 
ROTATIONAL CROP/GRAZING AND FEEDING RESTRICTIONS: 
The fOllowing rotational crops may be planted nine (9) months after the 
application of Commence EC. Do not rotate to any crops other than 
those listed bek)w as crop injury may occur. Cotton and soybeans may 
be planted any time following application of Commence EC Herbicide.

In those areas where at least twenty (20) inches of irrigation and/or 
rainfall (total) was used to produce the cotton or soybean crop. sorghum 
should not be planted for twelve (12) months after an application of 
Commence EC. If less than twenty (20) inches of total water was used 
to produce the cotton or soybean crop, do not plant sorghum for 
eighteen (18) months after an application of Commence EC. Cool, wet 
weather conditions during the early stage of growth may increase the 
possibility of injury to sorghum. 
In areas receiving greater than twenty (20) inches of rainfall per year, 
moldboard plow at least twelve (12) inches deep before planting sugar 
beets as a rotational crop. Do not rotate to sugar beets for thirteen (13) 
months after an application of Commence EC if less than twenty (20) 
inches of water was used to produce the cottoo or soybean crop. 
NOTE: Do not rotate to whot, oats, barleY,lYe or allilfa in the fan 
of the year of application or in the spring of the following year as 
crop Injury may occur. Cover crops may be planted anytime but stand 
reduction may occur. Do not graze or harvest these cover crops for food 
or feed. Do not allow livestock to graze on treated soybean vines or 
feed treated vines or vine trash to livestock.

GENERAL APPLICATION INSTRUCTIONS 
This Product Must Be Applied As A Preplant Incorpo­
rated Treatment. 
Do not apply aerially or through irrigation equipment. 
Ground Applications 
Broadcast Application: Apply Commence EC alone or in tank mix 
combinations by ground equipment using a finished spray volume of 10 to 40 
gallons of water per acre. NOTE: The use of an agriculturally approved drift 
reducing additive is required at finished spray vol-urnes of 10 to 15 
gallons per acre. Use nozzles suitable for broadcast boom application of 
herbicides. Coarse sprays are less likely to drift out of the target area than fine 
sprays. See "APPLICATION PRECAUTIONS" Section for specific 
recommendations to reduce spray drift. 
INCORPORATION DIRECTIONS 
General Directions: Use incorporation equipment that thoroughly mixes 
Commence EC into the top 2 to 3 inches of the final seedbed, or erratic weed 
control andlor crop injury may result. Incorporation equipment such as a disc 
will mix Commence EC approximately half as deep as the equipment is set to 
operate. For example a disc set to cut 4 inches deep will incorporate most of 
the Commence EC within the top 2 inches of soil. 
Incorporation: Application and immediate incorporation to a depth of 2 to 3 
inches is required unless the soil surface is dry. On dry soils, incorporation to a 
depth of 2 to 3 inches MUST be completed within 8 hours of Commence EC 
herbicide application. Soil must be in good tilth to allow for thorough mixing of 
the soil. Application to overly moist or wet soils will increase the potential for 
nff·site movement of Commence EC herbicide vapors and may result in poor 
. incorporation and unsatisfac-tory weed control. 
.. second incorporation is necessary, unless specifically stated, this time 
running the equipment in a different direction from the first. Incorporate the 
Commence EC uniformly into the top 2 to 3 inches of the final seedbed. 
Commence EC may be applied up to 3 weeks prior to planting. 
Recommended Equipment 
Any recommended incorporation tool may be used alone or in combina·tion 
with any other recommended tool. 
Disc: Set to cut 4 to 6 inches deep and operate at 4 to 6 mph. 
Field Cultivator: Set to cut 3 to 4 inches deep and operate at 5 mph or more. 
A field cultivator is defined as an implement with 3 to 4 rows of sweeps, spaced 
at intervals of 7 inches or less and staggered so that no soil is left untumed. 
Chisel points should not be used. 
Combination Seedbed Conditioners: Set to cut 3 to 4 inches deep and 
operate at a speed of at least 5 mph. These implements are defined as three or 
more tiUage devices combined and used as a single tool. For example C- or S­
shaped shanks with an effective sweep spacing of 6 to 9 inches (staggered 
so that no soil is left unturned) followed by a spike-tooth or flextine harrow, 
followed by a ground-driven reel or bas- ket. Only one incorporation is 
necessary. 
Rolling Cultivator: Set to cut 2 to 4 inches deep and operate at 6 to 8 mph. 
Rolling cultivators are adequate for use on coarse and medium teX1ured soils 
"'''Iy. 
j Conditioner (Do-All): Set to cut 2 to 4 inches deep and operate at 4 to 6 
mph. The Do-All is adequate for use on coarse and medium textured soils only. 
Mulch Treader (other similar disc·type implements): Set to cut 3 to 4 inches 
deep and operate at 5 to 8 mph. 
P.T.C. Driven Equipment (tillers, cultivators, hoes): Adjust to incorpo- rate 
Commence EC into the top 2 to 3 inches of the seedbed with rotors spaced to 
provide a clean sweep 01 the soit. Only one incorporation is necessary. P.T.O. 
driven equipment should not be operated greater than 4 mph. 
CULTIVATION AFTER PLANTING 
Soil treated with Commence EC herbicide may be shallow cultivated without 
reducing the weed control activity of Commence EC. Do not cultivate deeper 
than the treated soil since this may bring untreated soil to the surface and poor 
weed control may result. 
6 
SOIL PREPARATION 
Crop residues or Existing Weeds: Ground cover, such as crop resi­
dues or existing weeds, can interfere with the incorporation of Com­
mence EC into the soil. A manageable level of such ground cover will 
allow the Commence EC to be uniformly hcorporated Into the top 2 to 
3 inches of soil. If the level of the ~round cover is such that this cannot 
be done, till the soil prior to the application of Commence EC. 
Roughness: The soil surtace should be smooth enough to operate the 
sprayer and incorporation equipment efficiently and at speeds which 
insure a uniform application and incorporation of Commence EC. 
General Soli Conditions: To assure uniform incorporation of Com· 
mence EC, soil moisture conditions should be such that large clods can 
be broken up during the incorporation. Application to overly moist or wet 
soils will increase the potential for off-site movement of Commence EC 
herbicide vapors and may result in poor soil incorporation and 
unsatisfactory weed control. 
SOIL TEXTURE GUIDE 
The amount of Commence ® EC you apply will vary with the soil teX1ure 
and organic matter. A fine textured soil wiJi require more Commence EC 
per acre than a coarse soil. Choose the proper rate for each application 
based on the following soil teX1ure group. Do not exceed recommended 
rates.

are usually classified as fine textured soils. 
SPECIAL PRECAUTION 
Off·site movement of spray drift or vapors of Commence ® EC 
herbicide can cause fofiar whitening or yellowing of some plants. 
Prior to making applk:ations, read and strictly follow all precau­
tions and instructions in the APPLICATION PRECAUTIONS 
section. 
COTTON 
DIRECTIONS FOR USE 
Commence ~ EC selective herbicide must be utilized as a soil 
incorporated treatment when applied for the control of annual grass and 
broad leaf weeds in cotton. 
Commence EC may also be applied as par! of a sequential application 
program preceding cotton preemergence or postemergence herbicides to 
broaden the weed control spectrum compared to the products applied 
alone. Observe all precautions, instructions, and rotational cropping 
guidelines of each product's Jabel, including all references to potential 
carryover and crop injury warnings or restrictions. 
Water or liquid fertilizer may be used as a carrier for Commence EC when 
applied alone. 
REQUIREMENTS FOR PLANTING 
Do not apply Commence EC or Command 3ME herbicides to cotton 
unless either disulfoton or phorate organophosphate insecticide is applied 
in~furrow with the seed at planting time at a minimun of 0.75 pound per 
acre of active ingredient. Do not reduce the application rate of the 
organophosphate insecticide when Command 3ME herbicide is applied as 
a banded treatment. Failure to apply either disulfaton or phorate 
insecticides with Commence or Command in accordance with those in­
furrow label use directions can result in crop.phytotoxicity (bleaching) 
andlor stand reduction. Combinations of at planting systemic granular 
carbamate and organophosphate insecticides in conjunction with 
Commence or Command may result in injury to cotton. 
Refer to the insecticide product labels for appropriate in~furrow application 
directions and maximum use rates. Monitor application equipment to 
insure accurate and uniform placement of the i1secticide.

CROP SAFETY 
Crop injury may occur when Commence or Command is applied 
to coarse soils which contain greater than 80% sand and less 
than 20% clay. Diuron is not recommended for use at planting 
time when Commence or Command is used as plant injury 
and/or stand loss may occur. Fungicide treated seed or infurrow 
fungicides may be used in conjunc1ion with Commence or 
Command.

SEQUENTIAL APPLICATIONS 
COMMAND 3ME SEQUENTIAL TREATMENT 
GENERAL APPLICATION PRECAUTIONS 
IMPORTANT 
FAILURE TO OBSERVE THE PRECAUTIONS IN THIS SECTION 
OF THE LABEL WHEN USING COMMAND 3ME AS A 
PREEMERGENT SEQUENTIAL APPUCATION MAY RESULT IN 
INJURY TO SENSmVE PLANTS 
The microencapsulation of clomazone, the active ingredient in 
Command 3ME, is intended to minimize movement away from the 
site of application. Avoid making applications when spray particles 
may be carried by air cUlTents to areas where sensitive crops and 
plants are growi~, or when temperature inversions exist. Leave 
an adequate bu er zone between the area to be treated and 
desiratMe plants. Coarse sprays are tess likely to drift out of the 
target area than fine sprays. 
0 Foliar contact with spray drift or vapors may cause foliar whitening 
or yellowing of senSitive plants. Symptoms are QeneratJy 
temporary in nature, but may persist on some plant species. 
Application precautions must be taken as follows: 
0 Do not apply aerially or throU!~h irrigation equipment. 
0 Observe all buffer restrictions. 
Do not apply Command 3ME within 1.200 feet of the following 
areas: Towns and HOUsi~ Developments, Commercial Fruit/Nut 
or Vegetable 1 Production, mmercial Greenhouses or Nurseries. 
1Except for peppers, pumpkins, succulent peas, sweet corn, 
sweet potato, and winter squash. 
0 Before application, determine air movement and direction. 
Do not apply in winds above ·10 miles per hour. 
Do not a~PIY Command 3ME herbicide to non-field areas 
including enca rows, waterways, ditches, and roadsides. 
0 When moving spray equipment to noncontiguous sites, do not 
allow spray solution to spray or drip from tanks, hoses, fittings or 
spray nozzles and tips. 
Refer to Command 3ME Cotton use directions for additional 
requirements. 
COMMAND 3ME SEQUENTIAL TREATMENT 
SPRAY DRIFT PRECAUTIONS 
Non·target spray drift of Command 3ME herbicide should be avoided 
to prevent whitening of desirable plants. Drift is Influenced by many 
factors which include wind speed, spray pressure, particle size, 
nozzle type, and boom height 
0 Do not apply when weather conditions favor drift. 
Use a minimum spray volume of '0 gallons per acre. 
0 Use the lowest possible boom height while maintaining a uniform 
spray pattern, in conjunction with nozzle type, size, operating 
pressure and volume that meet a droplet size classification of 
coarse or greater. 
Refer to Command 3ME Spray Drift Management Section for 
addltionallnatructions. 
FHSt apply Commence EC as an Incorporated treatment prior to or 
immediately before planting at the rate listed below. Refer to the Incorporation 
DIrections section of the GENERAL APPLICATION INSTRUCTIONS for 
furth~r application directions. At or following planting, make an additional 
application of Command 3ME plus fluometuron herbicides as a

COMMENCE EC HERBICIDE FOLLOWED BY 
ACIFLUORFEN (BLAZER" OR TACKLE") HERBICIDE 
Following a soil incorporated application of Commence EC or tank mix­
ture with Commence EC, a pestemergence application of acifluorfen will 
control the following emerged broadleaf weeds: 
Broadleaf Weeds 
Common Cocklebur 
Hemp sesbania 
Eastern Black Nightshade 
Wild Mustard 
Purple Moonflower 
Pitted Morningglory 
Apply acifluorfen at a rate of 1 pint per acre with .25% crop oil concentrate 
to actively grOwing weeds at no more than the 4·leaf growth stage (do 
not count cotyledonary leaves, but only the fully developed true leaves). 
This timing generally correlates to soybean growth stages of the first to 
third trifoliate leaves. 
NOTE: Application of Commence(R) EC herbicide generally retards the 
development rate of weeds which may extend the period where acifluor· 
fen can be effectively applied. 
Read and follow aU precautions, restrictions, and warnings on all product 
labels.

COMMENCE EC HERBICIDE FOLLOWED BY 
SCEPTER" HERBICIDE 
Following a soil incorporated application of Commence EC or tank­
mixtures with Commence EC a postemergence application of Scepter 
herbicide will control the following emerged broadleaf weeds: 
BroMlea' Wads 
Cocklebur 
Pigweed 
(Palmar) 
(Smooth) 
(Tall W.terhemp) 
Apply Scepter after crop emergence but before weeds exceed a height 
of 12 inches. ~pIy at a broadcast rate of V3 pints per acre. Apply when 
weeds are actrvely growing. DO NOT apply Scepter postemergence 
when soybeans and weeds have been subjected to stress conditions 
such as temperature and moisture extremes. The total amount of 
Scepter should not exceed one half pint per acre per season. 
For postemergence applications, the addition of a non ionic surfactant or 
crop oil concentrate is required. The nonionic surfactant approved for 
use on growing crops should contain at least 80% active ingredient and 
should be appfied at a rate of 2 pints per 100 gallons of spray mixture. 
Apply the crop oil concentrate (COC) at the rate stated on the COC 
iabel. 
Additional Precautions: 
Read the Scepter label carefully for cautions and precautions relating to 
environmental hazards planting of rotation crops, sequential program 
uses of Scepter. harvest restrictions following postemergence 
treatments of Scepter, use of Scepter in conjunction with Classic e, 
Canopy., Pre-view., or Gemini·, grazing restrictions and other 
directions, precautions and limitations before applying Scepter. The use 
of Scepter is limited to those states listed on the Scepter label. If a 
Commence/Scepter preplant incorporated tank mix was used as the 
initial treatment, this sequential postemergence application can only be 
used in Alabama, Arkansas, Florida, Georgia, Louisiana, Mississippi, 
North Carolina, Oklahoma, South Carolina, Tennessee and Texas.

COMMERCIAL IMPREGNATION AND 
APPLICATION OF COMMENCE EC ON DRY 
BULK FERTILIZERS 
Commence herbicide may be impregnated on dry bulk fertilizers. When applied 
as directed Commence/dry bulk fertilizer mixtures provide weed control equal to 
that provided by the same rates at Commence EC applied in water. 
The Commencelfertilizer mixtures must be soil incorporated. For best results, 
Commence should be incorporated two times when applied impregnated on dry 
bulk fertilizers. The second incorporation should be delayed at least (5) days 
after the fjrst completed prior to planting, and should be run in a different 
direction from the first. Follow other Com-menee label recommendations for soil 
incorporation. 
Impregnation: Apply using a minimum of 200 pounds of dry bulk fertilizer per 
acre and up to a maximum of 450 pounds per acre with the recommended 
amount of Commence EC herbicide per acre. Use a closed rotary-drum mixer 
or a similar type of closed blender equipped with suitable spray equipment. The 
spray nozzle{s) should be positioned to provide a uniform, fine spray pattern 
over the tumbling fertilizer for thorough coverage. The physical properties of 
fertilizers vary, particularly in liquid absorptive capacity. When absorptivity is 
sufficient, simple spray impregnation of the fertilizer with Commence provides a 
satisfactory, dry mixture. If the absorptive capacity is inadequate, use of a highly 
absorptive powder is required to provide a dry, flowable mixture. Micro-cel E 
(Johns-Manville Products Corporation) is a recommended absorbent powder. 
Generally less than 2% by weight of Microcel E is required. 00 NOT 
impregnate Commence EC onto straight coated ammonium nitrate or straight 
limestone because these materials will not absorb the herbicide. Dry fertilizer 
blends containing mixtures of ammonium nitrate or limestone may be 
impregnated with Commence. 
The amount of Commence actually required in the preparation of individ-ual 
fertilizer mixtures should be determined carefully for each production operation. 
This is necessary to ensure that the amount of pesticide actually contained in 
the mixture applied to the soil represents the correct rate of use. Bulk fertilizer 
impregnated with Commence EC herbicide should be applied immediately, not 
stored. Care should be taken to ensure spreading procedures in the field do not 
place fertilizer treated with Commence in areas which cannot be incorporated. 
All state regulations, labeling, etc., of the mixtures are the responsibility of the 
seUer. 
For those rates not listed in the following table calculate the amount of 
Commence EC to be impregnated on a ton of dry bulk fertilizer using the 
following formula:

If fertilizer materials are excessively dusty, use diesel oil or other suitable 
additive to reduce dust prior to impregnation as dusty fertilizer will result in 
poor distribution during application. Crop injury and/or poor weed control 
may occur where the impregnated fertilizer is not uniformly applied. 
Special Precautions 
• All equipment used to apply Commence should be thoroughly cleaned 
immediately following use to ensure no contamination results which 
could cause injury to non labeled crops or desirable vegetation. Refer 
to "Sprayer Cleanup~ section for additional details and disposal of 
rinsates. 
• Equipment used to physically transport Commence treated fertilizer, 
including boots, augers conveyers, bins, etc. should be covered to 
prevent loss of fine particles and subjected to cleanup procedures 
previously described. 
• Mixing of Commence herbicide and dry fertilizer should be conducted 
in a blender which will ensure airborne particles and potential for 
volatiliZation are avoided. 
• Bulk containers should be tightly covered while the product is being 
transported and applied to reduce chances of Commence volatilization 
or product loss. 
• It is recommended that Dry Bulk Fertilizer impregnation operations 
using Commence not be conducted within 1/4 mile of residential areas 
or areas where Commence symptomology on desirable vegetation 
would not be tolerated.
