DIRECTIONS FOR USE
It is a violation of Federal law to use this product in a manner inconsistent with its labeling. Read all Directions for Use carefully before applying.
Use Restrictions in the State of New York: Sale and use of this product in Suffolk and Nassau counties in the state of New York is prohibited. Use of this product in the state of New York is limited to postemergence application with a maximum use of 18.9 fl oz (0.062 Ib of clopyralid) per acre per year providing that no other product containing clopyralid has been applied pre-plant or post-plant.
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.

GENERAL INFORMATION
Clopyralid Acid + MCPA Ester herbicide maybe used for selective control of broadleaf weeds in wheat, barley, oats and flax not underseeded with a legume, grasses grown for seed, rangeland, permanent grass pastures, and Conservation Reserve Program (CRP) acres.

PRECAUTIONS AND RESTRICTIONS
• Do not exceed a cumulative amount of 0.25 Ib active ingredient (a.i.) of clopyralid per acre per single crop year except in the state of New York (see New York Restrictions above).
• Do not contaminate irrigation ditches or water used for irrigation or domestic purposes.
• Do not use in greenhouses.
• Chemigation: Do not apply this product through any type of irrigation system.
• Many forbs (desirable broad leaf forage plants) are susceptible to Clopyralid Acid + MCPA Ester. Do not spray pastures containing desirable forbs, especially legumes, unless injury can be .tolerated.
However, thestahd and growth of established perennial grasses is usually improved after spraying, especially when rainfall is adequate and grazing is deferred.
• Do not use on newly seeded areas until grass is well established as indicated by vigorous growth and development of tillers and secondary roots.
• Do not use on bentgrass.Apply only once per crop cycle, except for grasses grown for seed (see specific use directions).
• Grazing Restriction for Rangeland and Grass Pastures: Do not forage or graze meat animals on treated areas within 7 days of slaughter. Do not forage or gJaze dairy animals on treated areas within 7 days after treatment.
• Do not transfer livestock from treated grazing areas (or feeding of treated hay) to sensitive broad leaf crop areas withouUirst allowing 7 days of grazing on an untreated pasture (or feeding of treated hay). If livestock are transferred within less than 7 days of grazing untreated pasture or eating untreated hay, urine and manure may contain enough clopyralid to cause injury to sensitive broad leaf plants.
• Field Bioassay Instructions: In fields previously treated with this product, plant short test rows of the intended rotational crop across the original direction of application in a manner to sample field conditions such as soil texture, soil pH, drainage, and any other variable that could affect the seed bed of the new crop. The field bioassay can be initiated at any time between harvest of the treated crop and the planting of the intended rotational crop. Observe the test crop for herbicidal activity, such as poor stand (effect on seed germination), chlorosis (yellowing), and necrosis (dead leaves or shoots), or stunting (reduced growth). If herbicidal symptoms do not occur, the test crop can be grown. If there is apparent herbicidal activity, do not plant the field to the test rotational crop; plant
only a labeled crop or crop listed in the table below for which the rotational interval has clearly been met. 

APPLICATION DIRECTIONS
Application Timing
Apply to actively growing' weeds. Extreme growing conditions such as drought or near freezing temperatures prior to, at or following application may reduce weed control and increase the risk of crop injury at all stages of growth. Only weeds that have emerged at the time of application will be affected. If foliage is wet at the time of application, control may be decreased. Applications of Clopyralid Acid + MCPA Ester are rainfast within 6 hours after application.

Application Rates
Generally, application rates at the lower end of the specified rate range will be satisfactory for young, succulent growth of susceptible weed species. For less sensitive species, perennials, and under conditions where control is more difficult (plant stress conditions such as drought or extreme temperatures, dense weed stands and/or larger weeds), the higher rates within the rate range will be needed. Weeds in fallow land or other areas where competition from crops is not present will generally require higher rates for control or suppression ..
Use of Surfactants
Addition of wetting and/or penetration agents is not usually necessary when using Clopyralid Acid +10 MCPA Ester; however, if a surfactant will be added to the spray solution, use, a non-ionic surfactant suitable for use in growing crops of at least 80% active ingredient and do not e'xceed 4 pints per 100 gallons of spray solution (0.5% v/v). Use of a surfactant in the spray mixture may increase weed control effectiveness but may reduce crop safety, particularly under conditions of plant stress.

Spray Coverage
Use sufficient spray volume to provide thorough coverage and a uniform spray pattern. Do not broadcast apply in less than 2 gallons of total spray volume per acre. For best results and to minimize spray drift, apply in a spray volume of 10 gallons or more per acre. As vegetative canopy and weed density increase, spray volume should be increased to obtain equivalent weed control. Use only nozzle types and spray equipment designed for herbicide application. To reduce spray drift, follow precautions under Avoiding
Injury to Non-target Plants.
Use with Sprayable Liquid Fertilizer Solutions
Clopyralid Acid + MCPA Ester is compatible with most non-pressurized liquid fertilizer solutions; however, a compatibility test Oar test) should be made prior to mixing. Jar tests are particularly important when a new batch of fertilizer, or pesticide is used, when the water source changes, or when tank mixture ingredients or concentrations are changed: A compatibility test is performed by mixing the spray components (in the desired order and proportions) into a clear glass jar before mixing in the spray tank.
Use of a compatibility aid such as Unite or Compex may help obtain and maintain a uniform spray solution during mixing and application. Agitation in the spray tank must be vigorous to compare with jar test agitation, For best results, liquid fertilizer should not exceed 50% of the total spray volume. Premix Clopyralid Acid + MCPA Ester with water and add to the liquid fertilizer/water mixture while agitating contents of the spray tank. Apply the spray the same day it is prepared while maintaining continuous agitation.
Note: Foliar-applied liquid fertilizers can cause yellowing or leaf burn of crop foliage.
