DIRECTIONS FOR USE

USE PRECAUTIONS

WARNING
Do not apply this product directly to or otherwise permit it to come into contact with vegetables, flowers, grapes, fruit trees, ornamentals or other desirable plants which are sensitive to 2,4-D or MCPA and do not permit spray mist containing it to drift onto them since even minute quantities of the spray may cause severe injury during both growing and dormant periods (coarse sprays are less likely to drift). Accordingly, application by airplane, ground rigs and hand dispensers should be carried out only when there is no hazard from drift. At higher temperatures, vaporization may cause injury to susceptible plants growing nearby.
Do not use on lawns or pastures until grass has become well established. Most legumes are usually damaged or killed. Do not contaminate irrigation ditches or water used for domestic purposes. Do not store near fertilizers, seeds, insecticides or fungicides.
To avoid injury to desirable plants, do not store, handle or apply other agricultural chemicals with the same containers used for this product. To avoid injury to desirable plants, containers used for this product should not be reused to store other materials. Rinse equipment and container thoroughly with water. Spray equipment used to apply 2,4-D or MCPA should not be used to apply other pesticides to susceptible crops. If it is necessary to do so, contact Dow AgroSciences Canada Inc. for detailed equipment clean-up procedures.
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.
DO NOT apply this product directly to freshwater habitats such as lakes, rivers, sloughs, ponds, prairie potholes, creeks, marshes, streams, reservoirs and wetlands, estuaries or marine habitats.
DO NOT contaminate irrigation/drinking water supplies or aquatic habitats by cleaning of equipment or disposal of wastes.

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 wing- or rotorspan.

Restricted Entry Interval (REI)
All crops—12-hour REI
Corn (field)—3-day REI
Established grass pastures, rangeland - 3-day REI
Non-cropland (annual and perennial weed control) – 9 day REI for scouting by foot.

General INSTRUCTIONS - CROP USE

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.

MIXING

Transfer System
For containers larger than 20 L, use a transfer system that avoids open pouring when transferring the liquid concentrate from such containers into the spray tank.

To Prepare A Spray
Add 1/2 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 water or oil with continued agitation.

WARNING: If preparing straight oil mixtures, do not let water get into the product or the finished mixture.

NOTE: This product in water forms an emulsion, not a solution, which tends to separate on standing. Agitate to prevent such separation and ensure uniformity of spray mixtures.

Selective Weed Control In Small Grains
Weeds differ in their susceptibility to 2,4-D 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.

Wheat, Barley and Rye
Spray from the 3 leaf expanded stage (15 cm) to just before the flag-leaf (shot-blade) stage. To avoid crop injury, do not treat during boot and flowering stages. Winter wheat and fall rye should be treated in early spring as soon as weeds appear and when the crop is in the full tillering stage to shot-blade stage. Maximum 1 application per year.

(1) Top growth control only.
(2) Better control will result from 2 treatments applied 1 week apart at 350 g/ha 2,4-D BEE-4 Herbicide.
(3) The higher rates may cause deformities and delayed maturity which will be offset by a higher relative yield from a less weedy crop.

Pre-Harvest Interval
Do not permit lactating dairy animals to graze fields within 7 days after application.
Do not harvest forage or cut hay within 30 days after application.
Withdraw meat animals from treated fields at least 3 days before slaughter.

Corn
Postemergence: Treat with 700 mL/ha when corn plants are 15 to 20 cm tall and most weeds have germinated but are still in the seedling stage. Use drop nozzles to keep spray off corn foliage. Do not cultivate until at least 2 weeks after treatment. Maximum 1 application per year.

Pre-Harvest Interval
Do not permit lactating dairy animals to graze fields within 7 days after application.
Do not harvest forage or cut hay within 30 days after application.
Withdraw meat animals from treated fields at least 3 days before slaughter.

Rangeland, Grass Pasture
To control susceptible weeds, use 2.0 to 3.5 L/ha in enough water for coverage. Maximum 2 applications per year.

Pre-Harvest Interval
Do not permit lactating dairy animals to graze fields within 7 days after application.
Do not harvest forage or cut hay within 30 days after application.
Withdraw meat animals from treated fields at least 3 days before slaughter.

Turf Weed Control
To control susceptible weeds in turf use 2.0 to 3.1 L/ha in enough water for coverage.
This product is only effective when applied to the leaves of actively growing weeds. This product will not prevent new weeds - apply only when weeds are present.
DO NOT apply more than two broadcast applications per season. This does not include spot treatments.
If weed populations do not warrant a broadcast application (e.g., entire lawn), consider spot treatments that target only weedy areas.

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 nontarget 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.
The field crew and the mixer/loaders must wear chemical resistant gloves, coveralls and goggles or face shield during mixing/loading, cleanup 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 for aerial applications to listed cereal crops, corn, pasture, rangeland and non-cropland
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:
DO NOT apply when wind speed is greater than 16 kmph at flying height at the site of application. 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.
Avoid direct applications to any body of water. Do not contaminate water through spray drift or by cleaning of equipment or disposal of wastes.
Fixed and rotary-winged aerial applications to field crops should be made in a minimum of 30 L/ha total spray mixture. Use boom pressure of 235 kPa or less. Avoid placing nozzles where spray will enter wing tip vortices.
Do not apply this product directly to, or otherwise permit it to come into direct contact with desirable crops, other desirable broadleaved plants or non-target species and do not permit spray mists to drift onto them.
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.
Do not use human flaggers.
Avoid Spray Drift: Apply only when there is little or no hazard from spray drift. Small quantities of the spray, which may not be visible, may seriously injure susceptible crops and damage sensitive non-target habitat. A method must be used to detect air movement, lapse conditions or temperature inversions (stable air) such as the use of balloons or a continuous smoke column at or near the spray site or a smoke generator on the spray equipment. If the smoke develops into layers or indicates a potential for hazardous spray drift, do not spray.
Buffer Zones: Appropriate buffer zones should be established between treatment areas and aquatic systems and treatment areas and significant wildlife habitat.

BUFFER ZONES TO PROTECT SENSITIVE HABITATS
Buffer zones are not required for applications with handheld equipment. Seasonal water bodies require buffer zones if there is water in them during application. Water bodies which do not fill on an annual basis need not be buffered.

Buffer Zones - Sensitive Habitats
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.

(1) For field sprayer application, buffer zones can be reduced with the use of drift reducing spray shields. When using a spray boom fitted with a full shield (shroud, curtain) that extends to the crop canopy, the labelled buffer zone can be reduced by 70%. When using a spray boom where individual nozzles are fitted with cone-shaped shields that are no more than 30 cm above the crop canopy, the labelled buffer zone can be reduced by 30%.
(2) For application to rights-of-way, buffer zones for protection of sensitive terrestrial habitats are not required.

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
For resistance management, 2,4-D BEE-4 Herbicide is a Group 4 herbicide. Any weed population may contain or develop plants naturally resistant to 2,4-D BEE-4 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 2,4-D BEE-4 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.
For further information or to report suspected resistance, contact Dow AgroSciences Canada Inc. at 1-800-667-3852 or at www.dowagro.ca.
