Engineering Controls Statements 
When handlers use closed systems, enclosed cabs, or 
aircraft in a manner that meets the requirements listed in 
the Worker Protection Standard (WPS) for agricultural 
pesticides [40 CFR 170.240 (d)(4-6)], the handler PPE 
requirements may be reduced or modified as specified in 
the WPS. 
USER SAFETY RECOMMENDATIONS 
Users should: 
Wash hands before eating, drinking, chewing 
gum, using tobacco or using the toilet.

Remove clothing immediately if pesticide gets 
inside. Then wash thoroughly and put on clean 
clothing. 
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. 
ENVIRONMENTAL HAZARDS 
Drift or run-off may adversely affect nontarget plants. 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 washwaters. Do not contaminate 
water intended for irrigation or domestic purposes. Do not 
apply when weather conditions favor drift from target site. 
GROUND WATER CONTAMINATION STATEMENT 
Most cases of groundwater contamination involving 
phenoxy herbicides such as MCPA have been associated 
with mixing/loading and disposal sites. Caution should be 
exercised when handling MCPA pesticides at such sites 
to prevent contamination of groundwater supplies. Use of 
closed systems for mixing and transferring this pesticide 
will reduce the probability of spills. Placement of the 
mixing/loading equipment on an impervious pad to 
contain spills will help prevent groundwater 
contamination. 
CLEANING OF EQUIPMENT 
When cleaning equipment, do not pour washwater on the 
ground; spray or drain over a large area away from wells 
and other water sources. 
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.

before transportation. If the container is not being refilled, 
return to the point of purchase. 
GENERAL PRODUCT INFORMATION 
USE PRECAUTIONS: MCP Amine Herbicide is 
injurious to most broad leaf plants and is useful for 
controlling these weeds in certain crops. Salts are the 
least volatile forms of MCPA and do not release enough 
vapors from treated areas to reduce yield of adjacent 
susceptible crops. This product is a salt of MCPA. 
Susceptible plants may, however, be injured by physical 
drift from the application of this product. However, 
several crops such as flax, rice oats, and small grains 
underseeded to legumes are more tolerant of MCPA than 
they are of 2,4-0. Apply this product only to varieties 
known to be tolerant of MCPA. Injury to crops may occur 
from this pesticide. If you are not prepared to accept 
some degree of crop injury, do not use this product. If 
you are uncertain concerning tolerant varieties or local 
use situations that may affect crop tolerance, contact your 
seed company or State Agricultural Extension Service for 
advice. Do not apply directly to or otherwise permit even 
Itltl 
minute amounts (such as spray drift) to contact fruit trees, 
vegetables, flowers, ornamentals, or other desirable 
plants susceptible to MCPA. DO NOT APPLY IN THE 
VICINITY OF COnON, GRAPES, TOBACCO OR 
TOMATOES. Do not use in or near a greenhouse. Do not 
spray when wind is blowing towards susceptible crops or 
ornamental plants. Do not apply this product through any 
type of irrigation system. 
Use coarse sprays to minimize spray drift since, under 
certain weather conditions, fine spray droplets may drift a 
mile or more. A spray thickening agent may be used with 
this pro9uct to aid in reducing spray drift. If used, follow 
all use recommendations and precautions on the product 
label. 
With ground equipment spray drift can be lessened by: 
1. Keeping the spray boom as low as possible. 
2. Applying 20 gallons or more of spray volume per acre. 
3. Using large-droplet producing nozzles. 
4. Using no more than 20 psi spray pressure at the 
nozzles. 
5. Spraying only when wind velocity is low. 
6. Stopping all spraying when wind exceeds 8 MPH. 
Do not use hollow cone-type nozzles or other nozzles 
that produce large amounts of line spray droplets. 
With aerial equipment, drift can be minimized by: 
1. Using no more than 20 psi spray pressure at nozzles. 
2. Using nozzle types and positions which do not produce 
fine spray droplets. 
3. Using a spray boom no longer than 3/4 the wing or 
rotor span 'of the aircraft. 
4. Spraying only when wind is less than 6 MPH. 
Determine air movement and direction before foliar 
application. Use a smoke generator or other means at or 
near the application site for the detection of air 
movement, air stability, or temperature inversions. Such a 
condition exists when there is little or no wind and air 
temperature is lower near the ground than at higher 
levels. Use appropriate drift control measures or avoid 
application when smoke is moving toward nearby 
desirable susceptible pli3nts or sensitive areas. 
Excessive amounts of this herbicide in the soil may 
temporarily inhibit seed germination or plant growth. 
Violent windstorms may move soil particles. If MCPA is 
on soil particles and they are blown onto susceptible 
plants, visible symptoms may appear. Serious injury is 
unlikely. The hazards of movement of MCPA on dust is

reduced if treated fields are irrigated or if rain occurs 
shortly after application. 
To avoid injury to desirable plants, do not handle or apply 
other agricultural chemicals with the same equipment 
used for MCPA unless it has been thoroughly cleaned 
with a suitable chemical cleaner. 
Local conditions may affect the use of herbicides. Consult 
your State Agricultural Experiment Station or Extension 
Service Weed Specialists for advice in selecting 
treatments from this label to best fit local conditions. Be 
sure that the use of this product conforms to all applicable 
regulations. Apply this product only as specified on this 
label. 
WHERE TO APPLY: MCP Amine Herbicide is used to 
control broad leaf weeds in flax, peas, small grains, 
established alfalfa and red clover, grass pastures, 
rangeland, and many non-crop areas. This product will kill 
or control the following weeds in addition to many other 
noxious plants susceptible to MCPA.

WHEN TO APPLY: Apply the product during warm 
weather when weeds are young and actively growing. 
Uniform spray coverage is necessary for best results. 
Generally the low dosages listed will be satisfactory for 
young, succulent growth of sensitive weed species. For 
less sensitive species and under conditions where control 
is difficult, the higher dosages will be needed. 
HOW TO APPLY: 
PREPARING THE SPRAY: Mix the MCP Amine' 
Herbicide with water unless otherwise indicated on the 
label. Fill the mixing tank or spray tank with approximately 
1/2 theilmount of water to be used for spraying. Add the 
required amount of product with agitation. Add the 
remainder of water while continuing to agitate. NOTE: 
adding oil, wetting agents, or other adjuvants to the spray 
may reduce selectivity to crops, possible causing crop 
damage. 
SPRAYING CONDITIONS: Use a moderate spray 
pressure of approximately 20 psi. Enough spray volume 
should be used to give good coverage of the weeds being 
sprayed, This is usually 5 to 30 gallons by ground 
application or 3 to 10 gallons by air unless directed 
otherwise under specific directions, Higher spray 
volumes may be useful in some situations to provide 
better spray coverage when weeds are especially dense 
and/or to reduce spray drift. 
WEED CONTROL APPLICATIONS 
FOR USE IN FLAX, GRAINS, PASTURES, 
RANGELAND: Do not forage or graze dairy and meat 
animals on treated areas within seven (7) days of 
slaughter and/or treatment. 
FLAX: For control of susceptible weeds, use 1/4 to 1/2 
pint of MCP Amine Herbicide per acre. Treat flax when 
3 to 8 inches tall before buds begin to form. Rates of 3/4 
to 1 pint per acre may be needed to control some weeds 
such as wild buckwheat, smartweed and thistles but flax 
may be injured at these rates. Consult Local Extension 
Service or University Specialists for advice on herbicide 
use on flax. Do not forage or graze meat animals on 
treated areas within se\ien (7) days of slaughter. 
WEED CONTROL IN SMALL GRAINS: NOTE: Do not 
forage or graze meat animals on treated areas within 
seven (7) days of slaughter, 
Wheat, Barley, Oats and Rye not underseeded with 
Legumes: Use 1/2 to 1 pint MCP Amine Herbicide per

acre for the most susceptible weeds when grains are in 
the 3 to 4 leaf stage or up to early boot stage. Apply when 
weeds are very small for best results. Use up to 3 pints 
MCP Amine Herbicide per acre for the less susceptible 
weeds after crop has tillered but not later than early boot 
stage. Do not apply during the boot to dough stage of the 
grain. 
Wheat, Barley, Oats and Rye underseeded with 
Alfalfa, Birdsfoot Trefoil, Lespedeza, Red, White or 
Ladino Clover ( Clover·Pacific Northwest Only): For 
emergency control of susceptible weeds such as mustard 
and lambsquarters, use i4 to Y, pint of MCP Amine 
Herbicide per acre as soon as possible after weeds 
emerge, but after seedling grain is at least 3 inches tall. 
The 114 to 112 pint per acre rate can produce injury to 
legumes. Balance the severity of your weed problem 
against the possibility of crop damage. The grain and 
weeds should form a protective canopy which, together 
with the use of low gallonage applied at low pressure, will 
reduce the risk of damage to the legumes. Treatment 
may be made up to the full tiller stage, but not in the boot 
to dough stages of the grain. To control certain weed 
species, 1 pint per acre may be needed. Do not use 
where small seeded legumes, especially vetch, sweet 
clover, trefoil or alfalfa, are seeded unless injury to them 
can be tolerated. 
When applying to small grains, use a minimum of 5 -10 
gallons of water per acre for ground application and at 
least 2 gallons of total spray per acre for aerial 
application. 
PEAS (Pacific Northwest Only) Use 1/4 to 3/4 pint of 
MCP Amine Herbicide in at least 15 to 30 gallons of 
water per acre when peas are 4 to 6 inches tall, before 
first flowering, and weeds are small. Do not apply 
during bloom period. Higher rates of 1/2 to 3/4 pint per 
acre may be used to improve control of difficult weeds, 
but crop injury is more likely to occur. Do not apply if 
peas are taller than 7 inches or when they are stressed 
for lack of soil moisture. Do not apply when air 
temperature is over 90" F. Do no graze treated fields or 
feed treated vies to livestock. 
NOTE: MCP can cause injury and delayed maturity in 
the pea crop. 
ESTABLISHED ALFALFA OR RED CLOVER (Clover· 
Pacific Northwest Only) : For control of yellow rocket 
and other susceptible annual weeds such as pennycress 
or fanweed, use 1 pint of MCP Amine Herbicide per 
acre. Use only 1/2 pint per acre on new stands after 
clover has two or more true leaves. Old stands of Red 
f,/tl 
clover may be retarded by application of MCPA. Apply in 
late fall after frost has killed legume top-growth and 
legumes are donmant. The temperature at time of 
spraying should be above 40°F. 
GRASS PASTURES (INCLUDING GRASS GROWN 
FOR SEED): Use 2 to 4 pints of MCP Amine Herbicide 
per acre in 2 to 120 gallons in airplane or ground sprayer 
application. Apply when weeds are small and actively 
growing for best results. Use the higher rates fOr 
whitetop, Canada thistle, buttercup and other more 
difficult to control weeds. Use only the lower rate on 
seedling grasses. Spray perennials in early bud to full 
bloom stage and regrowth in Fall; other weeds in spring 
or fall. Legumes may be injured or killed. Do not use this 
treatment where legumes, especially alfalfa, are present 
and desirable. In some areas bent, buffalo, centipede, 
dichondra, carpet and St. Augustine grasses may be 
susceptible to injury. Do not use on newly seeded areas 
until grass is well established. Do not use from early boot 
to milk stage where grass seed production is desired. 
CONTROL OF WHITEBRUSH ON RANGELAND: Use 3 
pints of MCP Amine Herbicide with 1 gallon of diesel oil 
or IMPEL RED and enough water for good spray 
coverage, usually 5 to 10 gallons per acre. Apply in 
spring or fall when plant foliage is well developed and 
actively growing. Spraying during bloom is recommended 
but not immediately after shedding of blossoms. 
Retreatments may be needed in succeeding years. 
NOTE: First mix the MCP Amine Herbicide in the water, 
then add the oil with agitation. Spray must be kept 
agitated during spraying to avoid separation in the tank. 
NON·CROP AREAS: For control of susceptible weeds in 
fencerows, fallowlands, rights-of-way, roadsides, and 
similar areas, use 6 pints of product per acre in enough 
water to give sufficient coverage. NOTE: on fallow land, 
do not plant any crop for 3 months after treatment or until 
chemical has disappeared from soil. 
SPOT TREATMENT: For weed control in pastures, 
rangelands and in non-crop areas such as fencerows, 
fanmyards, shelter-belts and roadsides: Use Y. pint of 
MCP Amine Herbicidejn 3 to 4 gallons of water or 3/4 
gallon per acre in sufficient water to give good coverage 
for most extensive areas to control weeds such as 
Canada thistle, whitetop, meadow buttercup and Texas 
blueweed. Apply to wet weeds thoroughly when weeds 
are growing vigorously, usually prior to bloom, in bud to 
early bloom and spray fall regrowth if necessary. Do not 
forage or graze livestock or dairy animals on treated

areas within 7 days of treatment. Local conditions may 
affect the use of this chemical. Consult State Agricultural 
Extension or Experiment Station weed specialists for 
specific recommendations for local weed problems and 
for information on possible lower dosages. 
TANK MIXES 
Read and follow the manufacturer's label 
recommendation for each tank mix product used for 
precautionary statements, directions for use, geographic 
and other restrictions. If these recommendations conflict 
with this label, do not use as a tank mix with MCP Amine 
Herbicide. All intended tank mix combinations should be 
used only in recommended areas on the same broadcast 
and weed species found on both labels. For application 
methods and other use specifications, use the most 
restricted limitations from labeling of both products. 
MCP Amine Herbicide may be tank mixed with 
Harmony® for selective post-emergence control of certain 
weeds on Wheat and Barley. Use MCP Amine Herbicide 
at the rate of 1/8 to 3/8 pound acid equivalent (a.e.) per 
acre. Nonionic surfactant may be added at 1 to 2 pints 
per 100 gallons of spray volume; however, the addition of 
a surfactant may increase the chance of crop injury. Use 
the 1 to 2 pint rate of surfactant with 1/8 pound a.e. of 
MCP Amine Herbicide. Higher rates may be used, but do 
not exceed highest rate allowed on the label. Always mix 
Harmony in water prior to adding MCP Amine Herbicide 
and surfactant. 
MCP Amine Herbicide may be tank mixed with 
Harmony® Extra for use on Wheat, Barley, and Oats. 
For best results, add MCP Amine to the tank at 1/8 to 3/8 
pound a.e. per acre. Nonionic surfactant may be added 
to mixture at 1 to 2 pints per 100 gallons of spray volume; 
however, adding surfactant may increase the potential for 
crop injury. In tank mixes containing 1/8 pound a.e. per 
acre of MCP Amine per acre, add 1 to 2 pints of 
surfactant; in tank containing 1/4 to 3/8 pound a.e. per 
acre, add 1 pint of surfactant. Higher rates of MCP 
Amine may be used, but do not exceed the highest rate 
allowed by this label. Always mix Harmony Extra with 
water prior to adding MCPA and add the surfactant last. 
MCP Amine Herbicide may also be tank mixed with 
Harmony Extra for the control of Com gromwell, Wild 
buckwheat, and Vetch (common and hairy). In Oats, also 
controls Vetch (common and hairy), Wild garlic, and Wild 
radish. 
MCP Amine may be tank mixed with Ally® after weeds 
have emerged. For best results, use 1/10 ounce of Ally 
7//1 
per acre, add MCP Amine to the tank at 1/4 to 1/2 pound 
a.e. per acre. Nonionic surfactant may be added to the 
mixture at 1/2 to 1 quart per 100 gallons of spray solution; 
however, adding surfactant may increase the potential for 
crop injury. Apply MCP Amine plus Ally after three to 
five-leaf stage, but before boot (with Durum and 
Wampum varieties, do not apply before tillering). Always 
mix Ally in water prior to adding MCP Amine and 
surfactant. Always add surfactant last. MCPA and Ally 
can be tank mixed for use on Wheat or Barley or in 
pastures and rangelands for the control of Blue mustard, 
Flixweed, Tansy mustard, Canadian thistle, Sow1histle, 
Corn gromwell, Prostate knotweed, Sunflower 
(common/volunteer), and Wild buckwheat. 
MCP Amine may be tank mixed with Express® for use on 
Wheat and Barley. For best results, add MCP Amine to 
the tank at 1/8 to 3/8 pound a.e. per acre. Nonionic 
surfactant may be added to the mixture at 1 to 2 pints per 
100 gallons of spray volume; however, adding surfactant 
may increase the potential for crop damage. Tank mixes 
containing 1/8 pound a.e. MCP Amine per acre, add 1 to 
2 pints of surfactant; in tank mixes containing 1/4 to 3/8 
pound a.e. of MCP Amine per acre, add 1 pint of 
surfactant. Higher rates of MCP Amine may be used, but 
do not exceed the highest rate allowed on the label. 
Always mix Express and water prior to adding MCPA and 
add the surfactant last. MCP Amine and Express may 
also be used to control Vetch (common and hairy), Wild 
garlic, and Wild rice. 
MCP Amine may be used annually with Glean® FC after 
weeds have emerged. For best results, use 1/6 to 113 
ounce of Glean FC per acre; add MCP Amine to the tank 
at 1/4 to 1/2 pound a.e. per acre. Nonionic surfactant 
may be added to the mixture at 1/2 to 1 quart per 100 
gallons of spray solution; however, adding surfactant may 
increase the potential for crop injury. Do not add 
surfactant when Glean FC and MCP Amine are tank 
mixed with a liquid fertilizer. Apply MCP Amine plus 
Glean FC after the three to five-leaf stage, but before 
boot. Applying a tank mixture of MCP Amine and Glean 
FC, with fertilizer when temperatures are below freezing 
or when crop is stressed in cold weather, just prior to 
winter dormancy, can r~.sult in severe foliar bum and/or 
crop injury. Do not apply MCP Amine plus Glean FC in 
combination with organophosphate insecticides. 
MCP Amine may be tank mixed with Finesse® in Wheat 
and Barley for postemergent broad leaf weed control. For 
best results, use 1/5 to 2/5 ounce of Finesse per acre, 
add MCP Amine to the tank at 1/4 to 1/2 pound a.e. per

acre. Nonionic surfactant may be added to the mixture at 
1/2 to 1 quart per 100 gallons of spray solution; however, 
• adding surfactant may increase the potential for crop 
injury. Do not add surfactant when MCP Amine and 
Finesse are applied with liquid fertilizer. Apply MCP 
Amine plus Finesse after the three to five-leaf stage, but 
before boot stage. Applying tank mixture of MCP Amine, 
Finesse, and a liquid fertilizer when temperatures are 
below freezing or when the crop is stressed from cold 
weather, just prior to winter dormancy, can result in foliar 
bum and/or crop injury. Do not apply MCP Amine plus 
Finesse in combination with organophosphate 
insecticides. 
MCP Amine may be used with Buctril® in Wheat, Barley, 
Oats, and Rye in the four-leaf stage, but before jointing. 
This tank mix improves control of Mustards, Pigweed, 
and Kochia. Apply to weeds up to four-leaf stage, two 
inches in height to one inch in diameter, whichever 
comes first. Use at a rate of 1/4 to 112 pound a.e. per 
acre of MCPA and 1 to 2 pints per acre of Buctril. Do not 
use this tank mixture in areas where Alfalfa or other 
legumes have been planted. 
MCP Amine may be tank mixed with Banvel® Herbicide 
for fall and spring-seeded wheat. Applications to fall­
seeded wheat must be made prior to jointing stage and to 
spring-seeded wheat before the wheat exceeds the five­
leaf stage. Apply 2 to 4 fluid ounces of Banvel and 8 to 
12 fluid ounces of MCP Amine per acre. For use on fall­
seeded wheat only, apply 3 to 4 fluid ounces of Banvel 
with 1 to 2 pints of MCP Amine per acre. Do not use 
unless potential crop injury will be acceptable. For fall­
seeded Barley, apply 2 to 4 fluid ounces of Banvel with 8 
to 12 fluid ounces of MCP Amine per acre. This mixture 
must be applied to fall-seeded Barley prior to jointing 
stage. For spring Barley varieties that are seeded during 
the winter months or later, follow the rates and timings 
given for spring-seeded Barley. For spring-seeded 
Barley, application must be made before Barley exceeds 
the four-leaf stage. Apply 2 to 3 fluid ounces of Banvel 
Herbicide with 8 to 12 fluid ounces of MCP Amine per 
acre. For fall and spring-seeded Oats, application must 
be made before spring-seeded Oats exceed the five-leaf 
stage. Applications to fall-seeded Oats must be made 
prior to the jointing stage. Use 2 to 4 fluid ounces of 
Banvel with 8 to 12 fluid ounces of MCP Amine per acre. 
For grasses grown for seed, such as Bermudagrass, 
Bluegrass, Fescue, and Ryegrass, application must be 
made after the grass seed crop begins to joint. For the 
best performance, make applications when weeds are in 
~/" 
the two to four-leaf stage and rosettes are less than two 
inches across. Use the higher level of listed ranges when 
treating more mature weeds or dense vegetative growth . 
Apply 1/2 to 2 pints of Banvel with 1 to 2 pints of MCP 
Amine per acre. 
Herbicides other than Sulfonylureas, such as MCP 
Amine, tank mixed with Banvel® SGF will offer more 
consistent control of sulfonylureas-resistant weeds. 
Surfactants are not recommended when applying this 
tank mix on small grains. This tank mix must be applied 
to fall-seeded Wheat prior to the jointing stage. For 
spring-~eeded Wheat, applications must be made before 
wheat exceeds the five-leaf stage. Apply 4 to 8 fluid 
ounces of Banvel SGF with water before adding 8 to 12 
inches of MCP Amine per acre. Always add MCP Amine 
after diluting Banvel SGF. For fall-seeded Wheat only, 
apply 6 to 8 fluid ounces of Banvel SGF with 1 to 2 pints 
of MCP Amine per acre. Do not use unless potential crop 
injury will be acceptable. For fall-seeded Barley, 
application must be made prior to jointing stage. Apply 4 
to 8 fluid ounces of Banvel SGF with 8 to 12 fluid ounces 
of MCP Amine per acre. For spring Barley varieties that 
are seeded during the winter months or later, follow the 
rates and timing given for spring-seeded Barley. Spring­
seeded Barley must be applied before Barley exceeds 
the four-leaf stage. Apply 4 to 6 fluid ounces of Banvel 
SGF with 8 to 12 ounces of MCP Amine per acre. For fall 
and spring-seeded Oats, this tank mix must be applied 
before spring-seeded Oats exceed the five-leaf stage. 
Applications to fall-seeded Oats must be made prior to 
the jointing stage. Apply 4 to 8 fluid ounces of Banvel 
SGF with 8 to 12 fluid ounces of MCP Amine per acre. 
For grasses grown for seed, such as Bermudagrass, 
Bluegrass, Fescue, and Ryegrass, tank mixes with 
Banvel SGF and MCP Amine may be used to control 
broad leaf weeds. 
MCP Amine may be tank mixed with Tordon® 22K, a 
restricted-use pesticide. For use on Barley, Oats, and 
Wheat not underseeded with a legume (which is not flood 
or sub-irrigated and not rotated to broad leaf crops). 
MCP Amine may be tank mixed with Curtail®. Apply 
Curtail at a rate of 2 to '2,~2/3 pints plus MCP Amine using 
up to 112 pint per acre in the spring to actively growing 
Wheat or Barley once four leaves have unfolded on the 
main stem and tillering has begun up to the jointing stage 
(first node of main stem detectable). To control or 
suppress weeds, make application at the maximum 
emergence of the target weeds, but before they exceed 
three inches in height or diameter (four rosettes). To

obtain season-long control of perennial weeds, such as 
Canada thistle, apply after the majority of the weed's 
basal leaves have emerged from the soil, but before bud 
stage. A late timing of application (when the grain is 
between the jointing and boot stages) may be used to 
treat later-emerging weeds; however, do not apply unless 
the risk of injury is acceptable. Do not apply after the 
boot stage. NOTE: Higher rates of Curtail or any 
application of Curtail following spring postemergence 
treatment with MCPA may increase risk of crop injury. 
MCP Amine may be tank mixed with Stinger® for weed 
control in Wheat, Barley, and Oats. Apply 1/4 to 1/3 pint 
of Stinger plus 1/2 to 1 pint of MCP Amine per acre from 
the three-leaf stage up to early boot stage of growth. For 
control of perennial weeds, such as Canada thistle, 1/3 
pint of Stinger per acre should be used. Russian 
knapweed will only be suppressed at this rate. 
MCP Amine may be tank mixed with Stinger for 
application in grasses grown for seed. Apply only to 
established grasses before the boot stage. Application in 
the boot stage and beyond can increase injury. Do not 
apply to Bentgrass unless injury can be tolerated. For 
control of late emergent Canada thistle, a pre-harvested 
treatment may be made after the grass seed is fully 
developed. Treatment of Canada thistle at the bud stage 
or later may result in less consistent control. Post­
harvest, fall treatments may be made to actively growing 
Canada thistle after the majority of basil leaves have 
emerged. Use 2 to 4 pints of MCP Amine with 1/4 to 2J3 
pint of Stinger per acre. For control of annual weeds and 
Canada thistle, treat as necessary, but do not exceed 213 
pint of Stinger per acre per season. NOTE: Do not tank 
mix Stinger with MCPA unless the risk of injury is 
acceptable. 
MCP Amine may be used in combination with Poasl® 
and Buctril® for grass and broad leaf weed control in Flax. 
Controls a mixed population of grasses and broadleaf 
weeds listed as susceptible on the respective product 
labels. Prepare the tank mix by adding MCP Amine to 
half the final water volume, then crop oil concentrate, 
then Poas!, then Buctril, and bring the mixture to the final 
volume. Agitation must be continuous from the time of 
mixing through spraying. Mix these three products 
according to the rates recommended on the respective 
product labels, up to a maximum of one pint of Buctril 
equivalent per acre, or up to a maximum of 1/4 pound 
MCP Amine a.e. per acre. Do not delay spraying 
broad leaf weeds even though grassy weeds are not in 
correct stage for treatment. Buctril or Poast applied with 
qll/ 
MCP Amine may cause leaf bum, retarded growth, and 
delayed maturity of the crop. Some reduced grass 
control may be experienced with this tank mix. Do not 
add ammonium sulfate or UAN solutions to this tank mix.
