DIRECTIONS FOR USE

Grazing Restriction

Do not permit lactating dairy animals to graze fields within 7 days after application.
Do not harvest forage or cut hay within 7 days after application.
Withdraw meat animals from treated fields at least 3 days before slaughter.

USE PRECAUTIONS

Do not overspray non-target terrestrial or aquatic habitats. These include: grassland, forested areas, shelter belts, woodlots, hedgerows, pastures, rangelands, and shrublands, lakes, rivers, sloughs, ponds, coulees, prairie potholes, creeks, marshes, streams, reservoirs, wetlands and estuarine/marine habitats. Avoid drifting of spray onto any body of water or other non-target areas.
Coarse sprays are less likely to drift, therefore, avoid combinations of pressure and nozzle type that will result in fine particles (mist). Do not apply when wind velocity and direction pose a risk of spray drift. Use caution when the wind is blowing towards a nearby sensitive crop, garden, terrestrial habitat (such as shelter-belt) or aquatic habitat.
Do not spray on exceptionally hot days over 27°C.
Clean spray equipment thoroughly after use and rinse with clean water. Do not use spray equipment to apply other pesticides to crops sensitive to this product. Do not reuse empty containers.

To Prepare a Spray
Add half the required amount of water or oil to the spray tank, then add with agitation the required amount of the product as shown for the different uses, and finally the balance of the water or oil with continued agitation. Provide agitation to ensure uniformity of spray mixture.

Product Specific Precautions
Read and understand the entire label before opening this product. If you have questions, call the manufacturer at 1-800-247-8013 or obtain technical advice from the distributor or your provincial agricultural representative. Application of this specific product must meet and/or conform to the following:

CROP USE

Ground Application

Use 100-240 L of water per hectare for ground application unless otherwise specified on tank-mix product labels. Do not exceed 275 kPa pressure for ground application. Do not spray in winds exceeding 25 km per hour.
During mixing, loading, application, clean-up and repair activities, wear coveralls over a longsleeved shirt, long pants, socks, shoes and chemical-resistant gloves. In addition, when mixing/loading, wear goggles or face shield. Aerial applicators and applicators using a closed cab are not required to wear chemical-resistant gloves.
Re-entry is not permitted until 12 hours after application for all agricultural scenarios.
Field sprayer application: DO NOT apply during periods of dead calm. Avoid application of this product when winds are gusty. DO NOT apply with spray droplets smaller than the American Society of Agricultural Engineers (ASAE) coarse classification. Boom height must be 60 cm or less above the crop or ground.

Aerial Application (including fixed and rotary wing aircraft)

Apply only by fixed-wing or rotary aircraft equipment which has been functionally and operationally calibrated for the atmospheric conditions of the area and the application rates and conditions of this label.
Label rates, conditions and precautions are product specific. Read and understand the entire label before opening this product. Apply only at the rate recommended for aerial application on this label. Where no rate for aerial application appears for the specific use, this product cannot be applied by any type of aerial equipment.
Ensure uniform application. To avoid streaked, uneven or overlapped application, use appropriate marking devices.
Apply a minimum of 30 L of spray solution per hectare depending on the type of application system being used. Use boom pressures of 235 kPa or less. Avoid placing nozzles where spray will enter wing tip vortices. Do not spray in winds exceeding 16 km per hour.

Aerial Use Precautions

Apply only when meteorological conditions at the treatment site allow for complete and even crop coverage. Apply only under conditions of good practice specific to aerial application as outlined in the National Aerial Pesticide Application Manual, developed by the Federal/Provincial/Territorial Committee on Pest Management and Pesticides.
DO NOT apply during periods of dead calm. Avoid application of this product when winds are gusty. DO NOT apply when wind speed is greater than 16 km/h at flying height at the site of application. DO NOT apply with spray droplets smaller than the American Society of Agricultural Engineers (ASAE) coarse classification. To reduce drift caused by turbulent wingtip vortices, the nozzle distribution along the spray boom length MUST NOT exceed 65% of the wingspan or rotorspan.
Do not apply to any body of water. Avoid drifting of spray onto any body of water or other nontarget areas.

Aerial Operator Precautions

Do not allow the pilot to mix chemicals to be loaded onto the aircraft. Loading of premixed chemicals with a closed system is permitted.
It is desirable that the pilot have communication capabilities at each treatment site at the time of application.
Aerial applicators must wear long pants and a long-sleeved shirt. Mixers/loaders must wear coveralls over a long- sleeved shirt, long pants, socks, shoes, chemical-resistant gloves, and goggles or face shield during mixing, loading, clean-up and repair activities. Aircraft must be closed cab. Mixer/loader and applicator must be different individuals. No human flaggers permitted.
Follow the more stringent label precautions in cases where the operator precautions exceed the generic label recommendations on the existing ground boom label. All personnel on the job site must wash hands and face thoroughly before eating and drinking. Protective clothing, aircraft cockpit and vehicle cabs must be decontaminated regularly.
DO NOT APPLY MORE THAN ONCE PER GROWING SEASON.

Surface runoff

To reduce runoff from treated areas into aquatic habitats, consider the characteristics and conditions of the site before treatment. Site characteristics and conditions that may lead to runoff include, but are not limited to, heavy rainfall, moderate to steep slope, bare soil, poorly draining soil (e.g. soils that are compacted, fine-textured, or low in organic matter such as clay).
Avoid applying this product when heavy rain is forecast.
Contamination of aquatic areas as a result of runoff may be reduced by including a vegetative strip (buffer zone) between the treated area and the edge of the water body.

Leaching
The use of this chemical may result in contamination of groundwater particularly in areas where soils are permeable (e.g. sand, loamy sand and sandy loam soils) and/or the depth to the water table is shallow.

TANK MIXES WITH Agri Star MCPA Ester 500
Use tank mixes only when they are registered and recommended. Read and follow the directions, warnings, precautions and grazing limitations on both products used in a tank mix. Ensure all components of tank-mix are registered for aerial application. Consult the labels of the tank-mix partners and observe the largest buffer zone (if specified) of the products involved in the tank mixture.
Do not exceed the application rates given on the label for each product.

TANK MIXES:
Agri Star MCPA Ester 500 + Avenge® 200-C

MIXING AND APPLICATION INSTRUCTIONS
1. Fill tank ½ full with water. Start agitation.
2. Add Agri Star MCPA Ester 500. When Avenge is used, add after Agri Star MCPA Ester 500when tank is ¾ full.
3. Complete filling of tank with water while maintaining continuous agitation.
4. Use 100-240 litres of water per hectare for ground application unless otherwise specified on tank-mix product labels.
5. Do not exceed 275 kPa pressure for ground application.

Buffer Zones to Protect Sensitive Habitat
Use of the following spray methods or equipment DO NOT require a buffer zone: handheld or backpack sprayer and spot treatment.
The buffer zones specified in the table below are required between the point of direct application and the closest downwind edge of sensitive terrestrial habitats (such as grasslands, forested areas, shelter belts, woodlots, hedgerows, riparian areas and shrublands), sensitive freshwater habitats (such as lakes, rivers, sloughs, ponds, prairie potholes, creeks, marshes, streams, reservoirs and wetlands) and estuarine/marine habitats.
When a tank mixture is used, consult the labels of the tank-mix partners and observe the largest (most restrictive) buffer zone of the products involved in the tank mixture.

RESISTANCE-MANAGEMENT RECOMMENDATIONS

Resistance-Management Recommendations
For resistance management, Agri Star MCPA Ester 500 is a Group 4 herbicide. Any weed population may contain or develop plants naturally resistant to Agri Star MCPA Ester 500 and other Group 4 herbicides. The resistant biotypes may dominate the weed population if these herbicides are used repeatedly in the same field.
Other resistance mechanisms that are not linked to site of action, but specific for individual chemicals, such as enhanced metabolism, may also exist. Appropriate resistance-management strategies should be followed.
To delay herbicide resistance:
Where possible, rotate the use of Agri Star MCPA Ester 500 or other Group 4 herbicides with different herbicide groups that control the same weeds in a field.
Use tank mixtures with herbicides from a different group when such use is permitted.
Herbicide use should be based on an IPM program that includes scouting, historical information related to herbicide use and crop rotation, and considers tillage (or other mechanical), cultural, biological and other chemical control practices.
Monitor treated weed populations for resistance development.
Prevent movement of resistant weed seeds to other fields by cleaning harvesting and tillage equipment and planting clean seed.
Contact your local extension specialist or certified crop advisors for any additional pesticide resistance-management and/or integrated weed-management recommendations for specific crops and weed biotypes.
For further information and to report suspected resistance, contact Albaugh Inc. representatives at 1-800-247-8013.
