• Protective eyewear (goggles, face shield or safety glasses) 
• Shoes plus socks, and 
• Chemical-resistant gloves made of barrier laminate, butyl rubber > 14 mils, nitrile rubber > 14 mils, or Viton® ≥ 14 mils when 
mixing, loading, or using any hand-held equipment. 
• Mixers/Loaders supporting aerial application to rangelands, pasture lands, or noncroplands must wear a chemical-resistant apron 
and a NIOSH- approved particle filtering respirator equipped with an N, R, P or HE class filter media with NIOSH-approval number 
prefix TC 84A. It is recommended that the respirator wearer be fit tested and trained in the use maintenance and limitations of the 
respirator. 
Discard clothing and other absorbent materials that have been drenched or heavily contaminated with this product’s concentrate. Do 
not reuse them. Follow manufacturer’s instructions for cleaning/maintaining Personal Prot ective Equipment (PPE). If no such 
instructions for washables exist, use detergent and hot water. Keep and wash PPE separately from other laundry. 
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. 607(d-f)], the handler PPE 
requirements may be reduced or modified as specified in the WPS. Pilots must use an enclosed cockpit that meets the requirements 
listed in the WPS for agricultural pesticides [40 CFR 170.607(d-f)]. 
For aerial application to high-acreage field crops: 
Handlers must use closed mixing loading systems during mixing and loading liquids for aerial application to barley, clover, flax, oats, 
pasture and rangeland grass, rye, triticale, wheat, and grass grown for seed. 
 
USER SAFETY RECOMMENDATIONS 
Users Should: 
• Wash hands before eating, drinking, chewing gum, using tobacco or using the toilet. 
• Remove clothing/PPE 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 
This pesticide may be toxic to fish, aquatic invertebrates and aquatic plants. Do not apply directly to water, to areas where surface 
water is present, or to intertidal areas below the mean high water mark. Do not contaminate water when disposing of equipm ent 
washwater or rinsate. Drift and runoff may be hazardous to aquatic organisms in water adjacent to treated areas. 
 
NON-TARGET ORGANISM ADVISORY: This product is toxic to plants and may adversely impact the forage and habitat of non-
target organisms, i ncluding pollinators, in areas adjacent to the treated site. Protect the forage and habitat of non- target 
organisms by following label directions intended to minimize spray drift. 
 
GROUNDWATER ADVISORY 
MCPA is known to leach through soil into groundwater under certain conditions as a result of label use. This chemical may leach 
into groundwater if used in areas where soils are permeable, particularly where the water table is shallow. 
 
SURFACE WATER ADVISORY 
This product may impact surface water quality due to runoff of rain water. This is especially true for poorly draining soils and soils 
with shallow groundwater. This product is classified as having high potential for reaching surface water via runoff for sever al 
weeks after application. A level, well -maintained vegetative buffer strip between areas to which this product is applied and 
surface water features such as ponds, streams, and springs will reduce the potential loading of clopyralid from runoff water and 
sediment. Runoff of this product will be reduced by avoiding applications when rainfall or irrigation is expected to occur within 48 
hours.

PRODUCT INFORMATION 
 
MCPA is effective on a large number of broadleaf weeds and is useful for controlling these weeds in certain crops. Several cr ops, 
such as flax, oats, and small grains underseeded to legumes, are more tolerant of MCPA than they are of 2,4-D. Crop varieties vary 
in response to MCPA, and some may be easily injured. Apply this product only to varieties known to be tolerant to MCPA. Injur y 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 to MCPA, contact your seed company or 
State Agricultural Extension Service for advice. 
NOTE: Adding oil, wetting agent or other surfactant to the spray may reduce selectivity to crops, possibly resulting in crop injury. 
RESTRICTIONS 
See individual crop use directions for additional restrictions and maximum application rates. 
The minimum retreatment interval is 21 days, except clover at 14 days. 
Do not apply this product through any type of irrigation system. 
Barley, oats, rye, wheat, clover, flax and peas treated with MCPA may be replanted immediately with any crop specified on an 
MCPA label or any crop for which a residue tolerance exists for MCPA. For crops not listed on an MCPA label, or on crops for which 
no residue tolerances for MCPA have been established, a 60-day plantback interval must be observed. 
When using on flax, grain, grasslands, and pastures - do not forage or graze dairy and meat animals on treated areas within 7 days 
of slaughter. 
For aerial application to high- acreage field crops: Handlers must use closed mixing loading systems during mixing and loading 
liquids for aerial application to barley, clover, flax, oats, pasture and rangeland grass, rye, triticale, wheat, and grass grown for seed. 
 
This product will kill or seriously injure many desirable forms of vegetation. Do not apply directly to flowers, fruits, grapes, tomatoes, 
ornamentals, cotton or other desirable plants. Vapors from this product may injure susceptible plants in the immediate vicinity. Do 
not apply when weather conditions favor drift from target area. 
 
LIMITATIONS 
Avoid use of small -diameter nozzles. Coarse sprays are less likely to drift. A spray thickening agent, such as Nalco- Trol, may be 
used with this product to aid in reducing spray drift. If used, follow all use recommendations and precautions on both product labels. 
Excessive amounts of this product in the soil may temporarily inhibit seed germination and plant growth. 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 towar d 
nearby desirable susceptible plants or sensitive areas.

MANDATORY SPRAY DRIFT MANAGEMENT 
 
Aerial Applications 
• Do not release spray at a height greater than 10 ft above the ground or vegetative canopy, unless a greater application 
height is Do not release spray at a height greater than 10 ft above the ground or vegetative canopy, unless a greater 
application height is necessary for pilot safety. 
• Applicators are required to use a medium or coarser droplet size (ASABE S572 and S641). 
• If the windspeed is 10 miles per hour or less, applicators must use ½ swath displacement upwind at the downwind edge 
of the field. When the windspeed is between 11-15 miles per hour, applicators must use ¾ swath displacement upwind 
at the downwind edge of the field. 
• Do not apply when wind speeds exceed 15 mph at the application site. If the wind speed is greater than 10 mph, the 
boom length must be 65% or less of the wingspan for fixed-wing aircraft and 75% or less of the rotor diameter for 
helicopters. Otherwise, the boom length must be 75% or less of the wingspan for fixed-wing aircraft and 90% or less of 
the rotor diameter for helicopters. 
• Do not apply during temperature inversions. 
 
Ground Boom Applications 
• User must only apply with the release height recommended by the manufacture, but no more than 4 feet above the 
ground or crop canopy. 
• Applicators are required to select a nozzle and pressure combination that delivers a medium or coarser droplet size 
(ASABE S572). 
• Do not apply when wind speeds exceed 15 mph at the application site. 
• Do not apply during temperature inversions. 
 
Boom-less Ground Applications: 
• Applicators are required to use a medium or coarser droplet size (ASABE S57) for all applications. 
• Do not apply when wind speeds exceed 15 mph at the application site. 
• Do not apply during temperature inversions. 
 
 
 
SPRAY DRIFT ADVISORIES 
THE APPLICATOR IS RESPONSIBLE FOR AVOIDING OFF-SITE SPRAY DRIFT. 
BE AWARE OF NEARBY NON-TARGET SITES AND ENVIRONMENTAL CONDITIONS. 
 
IMPORTANCE OF DROPLET SIZE 
An effective way to reduce spray drift is to apply large droplets. Use the largest droplets that provide target pest control. While 
applying larger droplets will reduce spray drift, the potential for drift will be greater if applications are made improperly or under 
unfavorable environmental conditions. 
 
Controlling Droplet Size - Ground Boom 
• Volume - Increasing the spray volume so that larger droplets are produced will reduce spray drift. Use the highest practical spray 
volume for the application. If a greater spray volume is needed, consider using a nozzle with a higher flow rate. 
• Pressure - Use the lowest spray pressure recommended for the nozzle to produce the target spray volume and droplet size. 
• Spray Nozzle – Use a spray nozzle that is designed for the intended application. Consider using nozzles designed to reduce drift. 
 
Controlling Droplet Size - Aircraft 
Adjust Nozzles - Follow nozzle manufacturers recommendations for setting up nozzles. Generally, to reduce fine droplets, nozzles 
should be oriented parallel with the airflow in flight. 
 
BOOM HEIGHT - Ground Boom 
Use the lowest boom height that is compatible with the spray nozzles that will provide uniform coverage. For ground equipment, the 
boom should remain level with the crop and have minimal bounce. 
 
RELEASE HEIGHT - Aircraft 
Higher release heights increase the potential for spray drift. 
 
SHIELDED SPRAYERS 
Shielding the boom or individual nozzles can reduce spray drift. Consider using shielded sprayers. Verify that the shields are not 
interfering with the uniform deposition of the spray on the target area. 
 
TEMPERATURE AND HUMIDITY 
When making applications in hot and dry conditions, use larger droplets to reduce effects of evaporation. 
 
TEMPERATURE INVERSIONS 
Drift potential is high during a temperature inversion. Temperature inversions are characterized by increasing temperature with 
altitude and are common on nights with limited cloud cover and light to no wind. The presence of an inversion can be indicated by 
ground fog or 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

5 
 
dissipates indicates good vertical air mixing. Avoid applications during temperature inversions. 
 
WIND 
Drift potential generally increases with wind speed. AVOID APPLICATIONS DURING GUSTY WIND CONDITIONS. 
Applicators need to be familiar with local wind patterns and terrain that could affect spray drift. 
 
Boom-less Ground Applications: Setting nozzles at the lowest effective height will help to reduce the potential for spray drift. 
 
Handheld Technology Applications: Take precautions to minimize spray drift. 
 
WEED RESISTANCE MANAGEMENT 
For resistance management, please note that this product contains a Group 4 herbicide. Any weed population may contain or 
develop plants naturally resistant to MCPA and other Group 4 herbicides. The resistant biotypes may dominate the weed population 
if these herbicides are used repeatedly in the same field. Appropriate resistance management strategies should be followed. 
 
When herbicides that affect the same biological site of action are used repeatedly over several years to control the same weed 
species in the same field, naturally-occurring resistant biotypes may survive a correctly applied herbicide treatment, propagate, and 
become dominant in that field. Adequate control of these resistant weed biotypes cannot be expected. If weed control is 
unsatisfactory, it may be necessary to retreat the problem area using a product affecting a different site of action. 
 
To delay herbicide resistance, take one or more of the following steps: 
 
• Rotate the use of MCPA-4 Amine or other Group 4 herbicides within a growing season sequence or among growing seasons with 
different herbicide groups that control the same weeds in a field. 
 
• Use tank mixtures with herbicides from a different group if such use is permitted; where information on resistance in target weed 
species is available, use the less resistance-prone partner at a rate that will control the target weed(s) equally as well as the more 
resistance-prone partner. Consult your local extension service or certified crop advisor if you are unsure as to which active 
ingredient is currently less prone to resistance. 
 
• Adopt an integrated weed-management program for herbicide use that includes scouting and uses historical information related to 
herbicide use and crop rotation, and that considers tillage (or other mechanical control methods), cultural (e.g. higher crop seeding 
rates; precision fertilizer application method and timing to favor the crop and not the weeds), biological (weed-competitive crops or 
varieties) and other management practices. 
 
• Scout before and after herbicide application to monitor weed populations for early signs of resistance development. Indicators of 
possible herbicide resistance include: (1) failure to control a weed species normally controlled by the herbicide at the dose applied, 
especially if control is achieved on adjacent weeds; (2) a spreading patch of non-controlled plants of a particular weed species; (3) 
surviving plants mixed with controlled individuals of the same species. If resistance is suspected, prevent weed seed production in 
the affected area by an alternative herbicide from a different group or by a mechanical method such as hoeing or tillage. Prevent 
movement of resistant weed seeds to other fields by cleaning harvesting and tillage equipment when moving between fields, and 
planting clean seed. 
 
• If a weed pest population continues to progress after treatment with this product, discontinue use of this product, and switch to 
another management strategy or herbicide with a different mode of action, if available. 
 
• Contact your local extension specialist or certified crop advisors for additional pesticide resistance-management and/or integrated 
weed-management recommendations for specific crops and weed biotypes. 
 
• For further information or to report suspected resistance, contact Nufarm at 855-280-6609. 
It is advisable to keep accurate records of pesticides applied to individual fields to help obtain information on the spread and 
dispersal of resistant biotypes. 
Contact your local sales representative, crop advisor, or extension agent to find out if suspected resistant weeds to this MOA have 
been found in your region. Do not assume that each listed weed is being controlled by this mechanisms of action. Co-formulated 
active ingredients are intended to broaden the spectrum of weeds that are controlled. Some weeds may be controlled by only one of 
the active ingredient in this product. 
 
Suspected herbicide-resistant weeds may be identified by these indicators: 
* Failure to control a weed species normally controlled by the herbicide at the dose applied, especially if control is achieved on 
adjacent weeds; 
* A spreading patch of non-controlled plants of a particular weed species; and 
* Surviving plants mixed with controlled individuals of the same species.

BARLEY, OATS, RYE, TRITICALE AND WHEAT 
Not underseeded with legumes - Apply as a water mix spray by ground sprayer or airplane. Use 1/2 to 1 pint per acre for the more 
susceptible weeds after crop has reached the 3 to 4 leaf stage up to boot stage. Use up to 1.6 pints per acre for less susceptible 
weeds after crop has tillered and up to boot stage. Do not spray from boot to dough stage. 
Underseeded with legumes - Alsike, Birdsfoot Trefoil, Lespedeza, Red and White clover: For emergency control of serious 
infestations of Mustard, Yellow rocket and other susceptible broadleaf weeds, apply 1/4 to 1/2 pint per acre. The 1/4 to 1/2 pint per 
acre rate can produce injury to legumes. Balance the severity of your weed problem against the possibility of crop damage. 
Make application after cereal is well tillered in the 4- leaf stage (4 to 8 inches tall) when legumes are 2 to 3 inches tall. Do not spray 
grain in the boot to dough stage. The nurse crop and weeds should provide a protecting canopy which, together with the use of low 
gallonage applied at low pressure, will reduce the risk of damage to the legumes. Do not apply to small grains underseeded wi th 
Sweet clover or Vetch, which are very susceptible. There is a definite risk to other legumes if only thinly protected by a canopy. 
When applying to small grains use a minimum of 10 gallons of water per acre for ground application and at least 2 gallons of total 
spray per acre for aerial application. 
 
RESTRICTIONS AND LIMITATIONS FOR USE ON BARLEY, OATS, RYE, TRITICALE AND WHEAT 
Do not apply more than 1.6 pints of this product (0.75 lbs. a.e.) per acre per year for barley, oats, rye, triticale and wheat. 
EMERGENCY CONTROL IN WHEAT - Use 1.6 pints per acre for perennial broadleaf weeds. Apply when weeds are approaching 
bud stage, but do not spray grain in the boot to dough stage. The 1.6 pints per acre application can produce injury to wheat. 
Balance the severity of your weed problem against the possibility of crop damage. Where perennial weeds are scattered, spot 
treatment is suggested to minimize the effect of crop injury. 
 
FLAX 
Use 1/4 to 1/2 pint of this product in 5 to 20 gallons of water per acre by ground equipment and at least 2 to 5 gallons of water per 
acre by air. Apply only when weeds are up and when flax is 2 to 8 inches high and before it comes into bud stage. Treatment after 
early bud stage may result in severe damage. If Canada thistle is present, it may be necessary to go as high as 1/2 pint per acre to 
prevent seed head production. Some injury to the flax may result. 
 
RESTRICTIONS AND LIMITATIONS FOR USE ON FLAX 
Do not apply more than 0.5 pint of this product (0.25 lb ae) per acre per year. 
 
PEAS [(INCLUDING CANNING PEAS)] 
FOR USE IN THE PACIFIC NORTHWEST ONLY – STATES OF IDAHO, OREGON AND WASHINGTON 
Use this product at 1/4 to 3/4 pint per acre. Apply in at least 2 to 10 gallons of total spray for aerial application and 5 to 30 gallons of 
water for ground equipment. Apply to peas after the 3 node stage and before the first pea flowering. Use when peas are 4 to 6 
inches tall. Peas may show slight injury, but they usually recover a few days after treatment. Do not use this product if the potential 
for pea injury is not acceptable. To control Canada thistle, use 1/2 to 3/4 pint per acre. Peas may be injured somewhat at the higher 
rate of application, but if Thistle growth is heavy, control will more than compensate for injury to peas. 
 
RESTRICTIONS AND LIMITATIONS FOR USE ON PEAS 
Do not apply more than 0.8 pints of this product (0.375 lb ae) per acre per year. 
Do not apply during bloom period of crop. 
Do not spray peas that are stressed from lack of moisture or when temperatures are over 90˚F. 
Do not graze treated fields or feed treated vines to livestock. 
 
 
CLOVER (RED, CRIMSON AND WHITE, EXCEPT DUTCH) 
FOR USE ON CLOVER IN THE PACIFIC NORTHWEST ONLY – STATES OF IDAHO, OREGON AND WASHINGTON 
For control of broadleaf weeds, with a total spray volume of 10 – 50 gallons per acre. Initial applications in late fall following frost 
when the clover is dormant. The temperature at the time of spraying should be above 40oF to provide adequate weed control.

7
