GENERAL INFORMATION

XRM-5171 Herbicide should be diluted in water and applied by ground or aerial application equipment

DIRECTIONS FOR USE

APPLICATION DIRECTIONS (Ground and Aerial Applications)

(1) Ground Application

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.
Best results are obtained when XRM-5171 Herbicide is applied to actively growing weeds in the 1 to 4 leaf (seedling) stage and when Canada thistle is between 10 cm and up to but not including the early bud stage. Poor weed control may result under cool or dry conditions.

Spring Wheat, Durum Wheat, Winter Wheat, Spring Barley, Oats
Apply to spring wheat, durum wheat, spring barley and oats from 3 leaf to just before flag leaf. Apply to winter wheat in the spring from the 3 tiller stage to just before the flag leaf stage. Do not apply later than the flag-leaf emergence stage. Apply 50-100 L/ha total spray volume by ground. Higher spray volumes will provide better coverage and weed control, particularly when the weeds are not actively growing.
Maximum 1 application per year.

Flax (including low linolenic acid varieties)
Apply to the flax when the crop is 5 to 15 cm tall. Early spraying will reduce the risk of crop injury. Apply XRM-5171 Herbicide in 50 to 100 L/ha total spray volume by ground equipment at spray pressures of 200 to 275 kPa. For optimum spray coverage, use flat fan nozzles tilted 45º forward to ensure better coverage. Maximum 1 application per year.
NOTE: Some delay in maturity and crop injury may result in flax from the use of the high rate but any potential yield reductions will usually be more than offset by increased yields due to better weed control.

Spray Preparation
Add half the required amount of water to the spray tank, then add with agitation the required amount of XRM-5171 Herbicide and the tank-mix partner if applicable. Add the balance of the water and continue to agitate while spraying.
The use of flood jet or hollow cone nozzles is not recommended because of uneven and inadequate spray coverage. Ensure thorough and uniform spray coverage over the entire leaf area of the target weeds.

(2) Aerial Application

Do not use human flaggers.

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.
Use XRM-5171 Herbicide alone or tank mixed with a product registered for aerial application as a broadcast treatment to cereal crops only. Apply the recommended rates of XRM-5171 Herbicide and tank mix partner as indicated elsewhere on this label. Apply in a spray volume of 30-50 L water/ha. Refer to the tank mix partner label for additional instructions, precautions and weeds controlled.
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 swath marking devices.

Use Precautions
Apply only when meteorological conditions at the treatment site allow for complete and even 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.

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 should be laundered 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:
 The interaction of many equipment-and-weather-related factors determine the potential for spray drift.
Users are responsible for considering all these factors when making decisions.
 The following drift management requirement must be followed to avoid off-target drift movement from aerial applications: Nozzles must always point backward parallel with the air stream and never be pointed downwards more than 45 degrees.

GENERAL USE PRECAUTIONS

Do not use in greenhouses.

Apply only when the potential for drift to areas of human habitation or areas of human activity (such as houses, cottages, schools and recreational areas) is minimal. Take into consideration wind speed, wind direction, temperature inversions, application equipment sprayer settings.

Sensitive Plants
Do not apply XRM-5171 Herbicide directly to or otherwise permit it to come into contact with sunflowers, legumes, fruit or vegetable crops, flowers or other desirable broadleaved plants and take precautions to avoid spray mists drifting onto them.

Crop Rotation
Fields previously treated with XRM-5171 Herbicide can be seeded to spring wheat, durum wheat, winter wheat, spring barley, oats and rye (not under-seeded to forage legumes, clover or alfalfa), canola, corn, field peas, flax, forage grasses, mustard, sugar beets or can be summer-fallowed. Seed only those crops listed above in the year following treatment. Do not seed to field peas for at least 10 months following treatment. Very dry soil conditions following application can result in a risk of injury to field peas grown in rotation. If severe drought conditions are experienced during the months of June to August inclusive in the year of application, delay seeding field peas an additional 12 months (total 22 months following application). Contact your local Dow AgroSciences Canada representative or retailer for more information before seeding field peas following drought conditions in the previous year.

Preharvest/Grazing Interval
 Do not cut or graze treated fields of wheat, barley, oats or flax within 7 days after application.
 Do not harvest wheat, barley, oats or flax within 60 days after application, or within 7 days after application when harvesting for forage.
 Withdraw meat animals from treated fields at least 3 days before slaughter.

Restricted Entry Interval (REI)
 Re-entry is not permitted until 12 hours after application for all agricultural situations.

Stress Conditions
When weeds are stressed due to drought, flooding or prolonged hot or cool temperatures (8C or less), control can be reduced or delayed since weeds are not actively growing. Weed escapes may occur under prolonged stress conditions or low fertility. Do not make applications to weeds stressed longer than 20 days due to lack of moisture as unsatisfactory control can result.

To Reduce Spray Drift
1. Do not apply with spray droplets smaller than the American Society of Agricultural Engineers (ASAE) coarse classification.
2. Use 30 to 100 L/ha of spray solution.
3. Spray when the wind velocity is 16 km/hr or less. Do not spray in dead calm or in gusty winds.

Sprayer Clean-Out Instructions
To avoid injury to desirable plants, thoroughly clean equipment used to apply this product before re-use or using it to apply other chemicals.
1. Immediately after spraying, completely drain the sprayer tank. Any contamination on the outside of the spraying equipment should be removed by washing with clean water.
2. First rinse:
 Spray the inside of tank with clean water and fill the sprayer with at least one tenth of the spray tank volume.
 Agitate and circulate for 15 minutes, and flush through booms and hoses.
 Remove end caps or open ball valves on the ends of each boom section, and flush solution through the boom ends to ensure there is no spray solution trapped between the boom end and the nozzles.
 Drain tank completely.
3. Second rinse:
 Fill the tank with clean water.
 Add All Clear Spray Tank Decontaminator, or Clean-Out Spray Tank Cleaner, or 1 L of household ammonia (containing a minimum of 3 % ammonia) per 100 L of water, or similar tank cleaning agent as per manufacturer’s recommendations while filling the tank with clean water.
 Agitate and then flush the boom and hoses with the cleaning solution. Top up with water making sure the tank is completely full. Allow to stand for 15 minutes with agitation. Flush the solution out of the spray tank through the spray booms. Remove end caps or open ball valves on the ends of each boom section, and flush solution through the boom ends to ensure there is no spray solution trapped between the boom end and the nozzles.
 If possible, let the solution stand in the sprayer tank and booms for an extended period of time, overnight if possible.
 After flushing the boom and hoses, drain tank completely.
 Remove nozzles and screens and clean separately with a cleaning agent or an ammonia solution (100 mL in 10 L water).
4. Third rinse:
 Rinse the tank with clean water and flush through the boom and hoses using at least one tenth of the spray tank volume.
 Remove end caps or open ball valves on the ends of each boom section, and flush solution through the boom ends to ensure there is no spray solution trapped between the boom end and the nozzles.
 Drain tank completely.
Do not use ammonia with chlorine bleach. Using ammonia with chlorine bleach will release a gas with a musty odour which may cause eye, nose, throat and lung irritation. Do not clean equipment in an enclosed area.

DIRECTIONS FOR USE

DO NOT APPLY BY AIR

ESTABLISHED TIMOTHY FOR HAY AND FORAGE PRODUCTION IN WESTERN CANADA
For the control of labeled weeds on Established Timothy for hay and forage production in Western Canada, apply XRM-5171 Herbicide at a rate of 2 L/ha. Apply only one post-emergent application per season. Do NOT apply within 7 days of harvest. For use in the prairie provinces and the Peace River, Okanagan and Creston regions of British Columbia only.

ESTABLISHED TIMOTHY FOR SEED PRODUCTION IN WESTERN CANADA
For the control of labeled weeds on Established Timothy for seed production in Western Canada, apply XRM-5171 herbicide at a rate of 1.5 - 2 L/ha. Apply only one post-emergent application per season.
Apply to the crop from 3 leaf to just before flag leaf. Do not cut or graze treated fields within 7 days after application. For use in the prairie provinces and the Peace River, Okanagan and Creston regions of British Columbia only. Timothy is particularly sensitive to stress conditions, and some crop injury or seed yield reduction may occur when herbicides are applied under stress (e.g. drought or frost) conditions.

LABELLED ANNUAL AND PERENNIAL BROADLEAVED WEEDS IN CANARY SEED (Phalaris canariensis)
For the control of labeled annual and perennial broadleaved weeds in Canary Seed (Phalaris canariensis), apply XRM-5171 Herbicide at a rate of 1.5 – 2.0 L/ha in a minimum of 100 L water/ha to thoroughly cover the weeds with a spray pressure of 200 to 275 kPa. Apply when weeds are in the seedling stage (2 to 4 leaf) and when Canary Seed (Phalaris canariensis) is in the 3 leaf stage to just before flag leaf emergence stage using a ground boom sprayer. Apply only one post-emergent application per season. Do NOT apply within 60 days of harvest. For use in the prairie provinces and the Peace River, Okanagan and Creston regions ONLY of British Columbia.

REFER TO THE MAIN XRM-5171 HERBICIDE LABEL FOR ADDITIONAL DETAILS AND INSTRUCTIONS.

BUFFER ZONES
Use of the following spray methods or equipment DO NOT require a buffer zone: hand-held 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).

NOTE: Applicators may recalculate a site-specific buffer zone for applications by combining information on current weather conditions and sprayer configuration for the following applications: all airblast applications, and for field and aerial applications which specify the following droplet size category wording on the product label: “ DO NOT apply with spray doplets smaller than the Amercian Society of Agricultural Engineers (ASAE) Coarse classification”. To access the Buffer Zone Calculator, please visit the Pest Management Regulatory Agency web site.

RESISTANCE MANAGEMENT RECOMMENDATIONS
For resistance management, XRM-5171 Herbicide is a Group 4 herbicide. Any weed population may contain or develop plants naturally resistant to XRM-5171 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 XRM-5171 Herbicide or other Group 4 herbicides within a growing season (sequence) or among growing seasons 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. To delay resistance, the less resistance-prone partner should control the target weed(s) as effectively as the more resistance-prone partner.
Herbicide use should be based on an integrated weed management program that includes scouting, historical information related to herbicide use and crop rotation, and considers tillage (or other mechanical control methods), cultural (for example, higher crop seeding rates; precision fertilizer application method and timing to favour the crop and not the weeds), biological (weedcompetitive crops or varieties) and other management practices.
Monitor weed populations after herbicide application for signs of resistance development (for example, only one weed species on the herbicide label not controlled). If resistance is suspected, prevent weed seed production in the affected area if possible by an alternative herbicide from a different group. Prevent movement of resistant weed seeds to other fields by cleaning harvesting and tillage equipment when moving between fields, and planting clean seed.
Have suspected resistant weed seeds tested by a qualified laboratory to confirm resistance and identify alternative herbicide options.
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.
