BROADCAST AERIAL APPLICATION

Directions for Use

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

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 to any body of water. Avoid drifting of spray onto any body of water or other non-target areas. Specified buffer zones should be observed.
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 during periods of dead calm or when wind velocity and direction pose a risk of spray drift. Do not spray when the wind is blowing towards a nearby sensitive crop, garden, terrestrial habitat (such as shelter-belt) or aquatic habitat.

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 mixers/loaders must wear long-sleeved shirt, long pants and chemical-resistant gloves during mixing/loading, clean-up and repair. 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.

Product Specific Precautions

Read and understand the entire label before opening this product. If you have questions, call the manufacturer at 1-800-667-3852 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 precautions.
WARNING - Do not spray when winds exceed 16 kmph. Do not spray in dead calm near sensitive plants. The “cloud” of suspended droplets may drift onto sensitive plants when the wind comes up.
Spray only when wind is blowing away from a sensitive crop, shelterbelt or garden.
Sensitive Plants - Vegetables, flowers, grapes, fruit trees and other desirable plants are sensitive to MCPA even in minute quantities. Care should be taken to avoid spraying these types of plants or allowing spray mist to drift onto these plants during both their growing and dormant periods. Coarse sprays are less likely to drift. At higher temperatures, vaporization may cause injury to susceptible plants growing nearby.
This product may cause damage to lawns or pastures if applied before the grass is well established. In addition, most legumes may be damaged or killed.
NOTE: Local conditions may affect the use of herbicides. Provincial agricultural authorities issue recommendations to fit local conditions. Be sure that use of this product conforms to all applicable regulations.
If this product is exposed to temperatures below 0C, it should be warmed to at least 5.0C and mixed thoroughly before using.


DIRECTIONS FOR USE

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
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.

GENERAL INSTRUCTIONS - CROP 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.

Restricted Entry Interval (REI)
REI for all Agricultural Scenarios - 12 hours

Ground Application
Apply 50 to 200 L of spray solution per hectare depending on the type of application equipment used.
Use sufficient water for even distribution. Spray at low pressures (200 to 275 kPa) when the weeds are actively growing.
Aerial Application (including fixed and rotary wing aircraft)
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.

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 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.

Spot Treatment
For spot treatment of weeds such as thistles using knapsacks, mix 20 mL of product/L of spray solution.
Wet all foliage thoroughly.

Selective Weed Control in Small Grains
Do not use on grain interplanted with a legume. Weeds differ in their susceptibility to MCPA Amine Herbicide and not all types can be controlled satisfactorily in crops. The amount of product to use will depend upon the susceptibility and whether the crops will tolerate this amount. See Table 1. Where specific rates are recommended for a crop in this Crop Use section, DO NOT exceed those specific rates.

Oats
Oats are more tolerant to MCPA than 2,4-D. Spray when conditions of weeds warrant up to the flag-leaf stage (shot blade). Maximum 1 application per year.

Wheat, Barley and Rye
MCPA Amine Herbicide is used for the control of susceptible weeds in wheat, barley and rye. Treatments can be made from the 3-leaf expanded to the early flag-leaf stage, and again from the milk stage to full maturity. Treatments made between emergence and 3-leaf stage may cause some crop injury, but are less likely to with MCPA Amine Herbicide than with 2,4-D amines. Winter wheat and fall rye should be treated in early spring, as soon as weeds appear and when the crop is in full tillering stage to the shotblade stage. Maximum 1 application per year.

Flax (linseed) (do not use on low linolenic acid varieties)
Treat flax with MCPA Amine Herbicide when flax is 5 cm tall to just before the buds begin to form. When control of MCPA resistant weeds is required, use 2,4-D Amine; however, some crop injury to the flax should be expected. Rates of MCPA Amine Herbicide over 1.1 L/ha may cause a delay in maturity which is usually more than offset by increased yield caused by weed control. Maximum 1 application per year.

Selective Weed Control in Small Grains Underseeded With Legumes
MCPA Amine Herbicide may be used on grain interplanted with alfalfa (except Flemish types such as alfa or dupuits alfa), red clover, ladino clover and alsike. Do not use on grain interplanted with sweet clover or birdsfoot trefoil. Spray with no more than 350 mL/ha on alfalfa and no more than 700 mL/ha on red clover, ladino and alsike when legumes are at about the 2nd true leaf stage. Where specific rates are recommended for a crop in this Crop Use section, DO NOT exceed those specific rates.

Asparagus
Treat asparagus with MCPA Amine Herbicide following a cultivation just before the first spears appear.
Use 3.5 L/ha. Treatment may be repeated at the end of the cutting season. Maximum 2 applications are ermitted per season with a minimum retreatment interval of 21 days.

Peas
Field and canning peas should be treated with MCPA Amine Herbicide at 700 mL/ha when 10 to 18 cmtall, using not less than 170 L/ha of water.

Established Grasses - Eastern Canada
For the control of yellow rocket and other susceptible winter annual weeds, spray with 2.1 L/ha of MCPA Amine Herbicide . Application should be made in early fall.

Established Legumes (alfalfa) and Grasses - Western Canada
To control such susceptible weeds as horsetail, hoary cress, shepherd’s purse and other perennials or winter annuals, spray with MCPA Amine Herbicide at 1.1 to 2.0 L/ha before growth of legumes and grasses starts in the spring.

Warning
Do not use on lawns or creeping grasses such as bent, except for spot spraying or on freshly seeded turf until grass has become well established. Most legumes are usually damaged or killed. For established grasses, pastures and rangeland, and established legumes, a maximum of 2 applications per season is permitted, with a minimum retreatment interval of 90 days.

BUFFER ZONES TO PROTECT SENSITIVE TERRESTRIAL AND AQUATIC HABITATS

Buffer zones are not required for applications with handheld or backpack equipment 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.

RESISTANCE MANAGEMENT RECOMMENDATIONS
For resistance management, MCPA Amine Herbicide is a Group 4 herbicide. Any weed population may contain or develop plants naturally resistant to MCPA Amine Herbicide 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 MCPA Amine Herbicide 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.
