chemical in areas where soils are permeable, particularly where the water table is shallow, may result in groundwater 
contamination. 
Nlost cases of groundwater contamination involving phenoxy herbicide such as MCPA have been associated with 
mixinglloading 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. mixinglloading equipment on an impervious pad to contain spills will help prevent 
~roundwater contamination.

GENERAL INFORMATION 
USE PRECAUTIONS: This product will kill or seriously injure many desirable forms of vegetation. Do not apply directly to 
flowers, fruits, vegetables, grapes, ornamentals, cotton or other desirable plants. Do not apply by aerial application in the 
vicinity of sugar beets. Do not use when there is hazard from drifting mists. (Coarse sprays are less likely to drift). Vapors 
from this product may injure susceptible plants in the immediate vicinity. 
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. 
CONTROLS THESE AND OTHER WEEDS 
Susceptible (most areas): Lambsquarters (goosefoot), marsh elder, mustards· (annual), puncturevine, ragweed, stinkweed 
(pennycress, fanweed), wild radish, yellow rocket or wintercress, cocklebur, goats beard, field pepper grass, dragon heat mint, 
beggarticks, pOison hemlock, hempnettle, shepherdspurse, annual sow thistle. 
Less susceptible: Buttercups, Canada thistle, dandelions, plantains, stinging nettle, perennial sow thistle, vetch, white top or 
hoary cress, Russian pigweed, sunflower, chervil, miner's lettuce, purslane, kochia. 
PREPARATION OF THE SPRAY 
Fill the spray tank with half the required amount of water, then add the recommended amount of MCPA LV ESTER and 
continue filling the spray tank with the balance of water. Keep agitator running when filling spray tank and during spray 
operations. For crop uses, do not mix with oil, surfactant or other adjuvants as this may reduce selectivity to crops resulting in 
crop damage or kill. 
AMOUNT OF SPRAY TO APPLY 
Apply 5 to 15 gallons of total spray per acre when making applications with ground equipment and 3 to 10 gallons of total spray 
per acre when making applications by aircraft unless directed otherwise under specific directions. Carefully read the 
ENVIRONMENTAL HAZARDS section of the PRECAUTIONARY STATEMENTS for further information on spray volume. 
SPRAY DRIFT MANAGEMENT 
Avoiding spray drift at the application site is the responsibility of the applicator. The interaction of many equipment-and­
weather-related factors determines the potential for spray drift. The applicator and the grower are responsible for 
considering all these factors when making decisions. 
Apply only as a medium or coarser spray (ASAE standard 572) or a volume mean diameter of 300 microns or greater for 
spinning atomizer nozzles. 
Apply only then the wind speed is 2-10 mph at the application site. 
Additional requirements for aerial application: . 
The boom length must not exceed 75% of the wingspan or 90% or the rotor blade diameter. 
Release spray at the lowest height consistent with efficacy and flight safety. Do not release spray at a height greater than 
10 feet above the crop canopy. 
When applications are made with a crosswind, the swath will be displaced downwind. The applicator must compensate for 
this displacement at the downwind edge of the application area by adjusting the path ofthe aircraft upwind. 
Do not make applications into temperature inversions.

Additional requirements for grounl Jam application: 
Do not apply with a nozzle height greater than 4 feet above the crop canopy. 
SELECTIVE SPRAYING 
Wheat, oats, barley and rye--Apply as a water mix spray by ground sprayer or airplane. Use Y2 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 1-5/8 pints per acre for the less 
susceptible weeds after crop has tillered and up to early boot stage. Do not spray from boot to dough stage. 
Do not forage or graze dairy animals on treated areas within 7 days after treatment. Do not apply more than 1-5/8 pints (314 
lb. ae) MCPA LV Ester per acre per year. 
FLAX 
Use 1/4 to 1/2 pint per acre. Apply by ground sprayer or by airplane. Apply only when weeds are up and when flax in 4 to 
8 inches high and before it comes into bud. Treatment after early bud stage may result in severe damage. If Canada 
thistle is present, it may be necessary to go as high as 3/4 pint per acre to prevent seed head production. Some injury to 
the flax may result. 
Do not forage or graze dairy animals on treated areas within 7 days after treatment. Do not apply more than 1/2 pint (1/4 lb. 
ae) MCPA LV Ester per acre per year. 
GRASSES 
Established grassland--Use 1 to 3 pints per acre in sufficient water (10 to 100 gallons) by airplane or ground sprayer 
application and give thorough coverage. Use higher rate for white top, Canada thistle, and other less susceptible weeds. 
Spray perennials in early bud to full bloom stage and regrowth in fall; other weeds in spring or fall, when actively growing. 
Do not forage or graze dairy animals on treated areas within 7 days after treatment. Do not apply more than 3% pints (1-1/2 
Ibs. ae) MCPA LY Ester per acre per year. Do not apply more than 2 applications per year with a minimum retreatment 
interval of 21 days. 
NON-CROP SPRAYING ALONG FENCE ROWS AND ROADSIDES 
Canada thistle, white top and meadow buttercup--For spot treatment, use % pint in 3 to 4 gallons of water, or 3-1/4 pints in 
sufficient water to give coverage for most extensive areas. Spray to wet weeds thoroughly when in bud to early bloom and 
again on fall regrowth. 
Broadcast Treatment: Do not apply more than 3% pints (1-1/2 Ibs. ae) MCPA LV Ester per acre per year. Do not apply 
more than 2 applications per year with a minimum retreatment interVal of 21 days. Spot Treatment: Do not apply more 
than 6 pints (3 Ibs. ae) MCPE Phenoxy Herbicide per acre per year. 
STORAGE AND DISPOSAL 
STORAGE: Store in a secure area, in original container only, away from fertilizers, food, or feed. Do not contaminate water, 
food, or feed by storage or disposal. 
PESTICIDE DISPOSAL: Pesticide wastes are toxic. Improper disposal of excess pesticide, spray mixture, or rinsate is a 
violation of Federal Law. If these wastes cannot be disposed of according to label instructions, contact your State Pesticide 
or Environmental Control Agency, or the Hazardous Waste Representative at the nearest EPA regional office for guidance. 
CONTAINER DISPOSAL: Metal containers: Triple rinse (or equivalent). Then offer for recycling or reconditioning, or 
puncture and dispose of in a sanitary landfill, or by other procedures approved by state and local authorities. Plastic 
containers: Triple rinse (or equivalent). Then offer for recycling or reconditioning, or puncture and dispose of in a sanitary
