PRODUCT INFORMATION
Liquid Achieve™ SC Herbicide is a systemic, postemergence herbicide for the selective control of wild oats, volunteer tame oats, green foxtail, yellow foxtail, barnyard grass and Persian Darnel in spring wheat, durum wheat, winter wheat, barley, triticale, spring rye, winter rye, and selected forage grasses (except Timothy) grown for seed only.
DIRECTIONS FOR USE
Rates of Use
Apply Liquid Achieve SC Herbicide at 0.5 L/ha in 50-100 L/ha of water.
Note: Always add Turbocharge D Adjuvant or Intake Adjuvant to the spray solution at a rate of 0.5 L per 100 L of water (0.5% v/v). Under adverse conditions, such as dense weed population, late weed growth stage, or poor environmental conditions apply 1.0% V/V of Intake Adjuvant (10 L Intake Adjuvant /1000 L spray mixture). The incorrect Turbocharge D Adjuvant or Intake Adjuvant rate can result in unacceptable weed control or crop injury. See MIXING and SPRAYING INSTRUCTION sections.
Only one application per season is permitted.
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 and sprayer settings.
Liquid Achieve SC Herbicide can be used on the following crops:
CEREAL CROPS: (Spring Wheat, Durum Wheat, Winter Wheat, Barley, Triticale, Spring Rye and Winter Rye) Liquid Achieve SC Herbicide can be used in all varieties of spring wheat (including Canada Western red spring, amber durum, soft white spring, extra strong and Canada prairie spring), red winter wheat, all 2 or 6 row varieties of barley (malting and feed varieties), all varieties of triticale, spring rye and winter rye.
Note: Tillered cereal crops may incur injury if applications are made within 48 hours of freezing temperatures. Non-tillering cereal crops which are exposed to temperatures of 4°C or less up to 48 hours before or after application may incur injury. Tank mixing Liquid Achieve SC Herbicide with a broadleaf weed herbicide under adverse conditions may increase severity of crop injury. Crops under stress from foliar diseases or low fertility are more susceptible to injury from Liquid Achieve SC Herbicide.
Do not use in tame oat crops. Avoid drift onto tame oat and corn crops.
Do not replant treated areas to tame oats or corn for at least 4 weeks after application.
In Eastern Canada Liquid Achieve SC Herbicide is to be used only for the control of wild oats in spring wheat, winter wheat, durum wheat, barley and all varieties of triticale and spring and winter rye.
Minimum Interval to Harvest
Immature cereal crops may be grazed or cut for hay 16 days after treatment. Grain may be harvested 60 days after treatment. Mature straw may be fed to livestock. Do not feed or graze underseeded forage crops in the year of treatment, sufficient data are not available to support this use.
CEREAL CROPS UNDERSEEDED TO FORAGE LEGUMES: alfalfa, birdsfoot trefoil, sainfoin and clovers.
Note: Do not tank-mix Liquid Achieve SC Herbicide with any broadleaf herbicides when applying to cereal crops underseeded to forage legumes, as the forages may be injured or killed.
WEEDS CONTROLLED
Apply Liquid Achieve SC Herbicide to actively growing weeds for best results. Weeds emerging after application of Liquid Achieve SC Herbicide will not be controlled.
CROP: WHEAT, DURUM, BARLEY, TRITICALE, RYE
WEEDS CONTROLLED: WILD OATS, VOLUNTEER OATS
WEED GROWTH STAGE (ZADOKS or BBCH): 1-6 leaf (11,20 to 14,22)
WEEDS CONTROLLED: GREEN FOXTAIL, YELLOW FOXTAIL
WEED GROWTH STAGE (ZADOKS or BBCH): 1-5 leaf (11,20 to 14,21)
WEEDS CONTROLLED: BARNYARD GRASS, PERSIAN DARNEL
WEED GROWTH STAGE (ZADOKS or BBCH): 1-4 leaf (11 to 14)
Optimum weed control and crop yield response occurs when grassy weeds are removed before they begin to tiller. Refer to the illustration.
Weed Control Notes
- Perennial grasses such as quack grass will not be controlled.
- Susceptible grassy weeds treated with Liquid Achieve SC Herbicide cease growth soon after application, however, complete die-back of the weeds could take up to 2 weeks.
- When grass weeds are stressed due to drought, heat, lack of fertility, flooding or prolonged cool temperatures, control can be reduced or delayed since the grasses are not actively growing. Grass escapes or re-tillering may occur when application is made under prolonged stress conditions. Optimum weed control will be obtained if application of Liquid Achieve SC Herbicide is delayed until the stress conditions have ended and weeds are once again actively growing.
- The herbicidal activity of Liquid Achieve SC Herbicide can be negatively affected if water containing high concentrations (>400 ppm) of bicarbonate ions is used as a diluent. Water from deep wells is more likely to contain high concentrations of bicarbonate ions. Ammonium sulfate at 9 to 18 kg per 1000 litres of spray solution can be used to counteract this antagonistic effect. Use only granular or liquid ammonium sulfate formulations which do not contain additional wetters or surfactants.
- Liquid Achieve SC Herbicide is not affected by rain falling one hour or more after application.
TANK MIXES OF LIQUID ACHIEVE SC HERBICIDE WITH BROADLEAF WEED HERBICIDES
Liquid Achieve SC Herbicide alone will not control broadleaf weeds. For broad spectrum control of both annual grasses and broadleaf weeds, Liquid Achieve SC Herbicide can be tank mixed with a variety of broadleaf weed herbicides. Refer to the following table for details and additional guidance. Read the appropriate broadleaf herbicide label for information on broadleaf weeds controlled.
Tank Mixing Notes
1. Read and strictly adhere to the use directions and precautions on the label of the product(s) that is/are being tank mixed with Liquid Achieve SC Herbicide. Also note all environmental restrictions and guidance such as rain fastness and maximum spraying temperatures on the label of the other product(s) being tank mixed.
2. Do not tank mix with amine formulations of 2,4-D or with amine formulations of MCPA or with any other herbicide, insecticide, fungicide, fertilizer solution or adjuvant not recommended on the label as poor grass control and/or unacceptable crop injury may result.
3. With reduced water volumes, tank mixes with Buctril M, Thumper or Pardner may result in some initial injury in the form of "tip burn". This injury, however, will not have any adverse effect on crop maturity or yield.
4. Do not tank mix Liquid Achieve SC Herbicide with broadleaf herbicides when applying to cereal crops underseeded to forage legumes as the forages may be injured or killed.
5. Tank mixes with the high rate of Attain XC A Herbicide + Attain XC B Herbicide or high rate of Prestige XC Herbicide may cause temporary crop injury if applied before the 4 leaf stage, however, yield will not normally be affected. These tank mixes may provide a lower level of wild oat control than Liquid Achieve SC Herbicide alone.
6. Temporary crop injury may occur with registered tank mixes, in particular 2,4-D Ester/dichlorprop products, under extreme weather conditions or when the crop is suffering from stress due to inadequate or abnormally high moisture levels, or extreme temperatures. Barley may be injured with tank mixes of 2,4-D Ester/dichlorprop and Buctril M plus MCPA.
7. Herbicides not listed on this label for tank mixing with Liquid Achieve SC Herbicide may be applied separately in sequence. Always apply Liquid Achieve SC Herbicide first and allow at least 7 days after the application of Liquid Achieve SC Herbicide before applying the other herbicide. Herbicides labelled for tank mixing with Liquid Achieve SC Herbicide may also be applied sequentially, either before or after application of Liquid Achieve SC Herbicide.
TANK MIXES OF LIQUID ACHIEVE SC HERBICIDE TANK-MIX WITH INSECTICIDE
Liquid Achieve SC Herbicide alone or in combination with Buctril M or Pardner can be tank mixed with Matador 120EC Emulsifiable Concentrate Insecticide or Decis Flowable for one pass weed and insect control. Always add MATADOR 120EC Emulsifiable Concentrate or Decis Flowable to the spray tank after the herbicides but before adding Turbocharge D Adjuvant or Intake Adjuvant.

MIXING INSTRUCTIONS
Follow the mixing instructions below for adding Liquid Achieve SC Herbicide to the spray tank.
1. Only use sprayers in good running condition with high agitation. Ensure the sprayer and pre-mix tank is cleaned according to instructions on label of the product used prior to Liquid Achieve SC Herbicide. Use only clean water for the spray solution. Ensure that all in-line strainer and nozzle screens in the sprayer are 50 mesh or coarser. Screens of 80 mesh size or finer should not be used.
2. Begin to fill sprayer tank or premix tank with clean water, and engage agitator. Agitation must be continued throughout the entire mixing and spraying procedure.
3. When the sprayer or premix tank is three quarters full of water, add Liquid Achieve SC Herbicide. If more than 1 case of Liquid Achieve SC Herbicide is to be used, add the Liquid Achieve SC Herbicide from all cases prior to adding tank mixed products or Turbocharge D Adjuvant or Intake Adjuvant.
4. If tank mixing, add the recommended product(s) next.
5. Lastly, add Turbocharge D Adjuvant or Intake Adjuvant, and then continue to fill tank to desired level with water.
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.
GROUND SPRAYING INSTRUCTIONS
1. Apply in a spray volume of 50-100 L/ha at a pressure of 275 kPa to ensure proper dispersion, spraying characteristics and performance of Liquid Achieve SC Herbicide.
2. Flat fan nozzles of 80o or 110o are recommended for optimum coverage. Do not use floodjet nozzles or controlled droplet application equipment. Nozzles may be angled forward 45o to enhance penetration of the crop and provide better coverage. Ensure that all in-line strainer and nozzle screens in the sprayer are 50 mesh or coarser. Screens of 80 mesh or finer should not be used.
3. Always ensure that agitation is continued until spraying is completed, even if stopped for brief periods of time. If the agitation is stopped for more than 5 minutes, re-suspend the spray solution by running on full agitation prior to spraying. Do not begin spraying until fully re-suspended. Liquid Achieve SC Herbicide must be sprayed within the same day of mixing.
4. When spraying is completed and prior to using other products, ensure the sprayer tank is thoroughly rinsed with clean water to remove any remaining Liquid Achieve SC Herbicide residues. Using a pressure washer and the addition of a detergent or Agral 90 to the rinse water will enhance removal of residues.
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) medium classification. Boom height must be 60 cm or less above the crop or ground.
AERIAL APPLICATION
Generic Aerial Application Label Instructions - Directions for Use

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.
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) medium 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.
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.
AERIAL SPRAYING INSTRUCTIONS
1. Apply in a spray volume of 30 to 45 L/ha at a pressure of 140-275 kPa to ensure proper dispersion, spraying characteristics and performance of Liquid Achieve SC Herbicide.
2. Flat fan nozzles of 80o or 110o are recommended for optimum coverage. Do not use floodjet nozzles or controlled droplet application equipment. Ensure that all in-line strainer and nozzle screens in the sprayer are 50 mesh or coarser. Screens of 80 mesh size or finer should not be used.
3. Always ensure that agitation is continued until spraying is completed, even if stopped for brief periods of time. If the agitation is stopped for more than 5 minutes, re-suspend the spray solution by running on full agitation prior to spraying. Liquid Achieve SC Herbicide must be sprayed within the same day of mixing.
4. Do not apply Liquid Achieve SC Herbicide if the wind is more than 13 km/h. This will avoid spray drift onto non-target areas.
5. Do not spray Liquid Achieve SC Herbicide if tame oats are present in adjacent, downwind fields.
6. When spraying is completed and prior to using other products, ensure the sprayer tank is thoroughly rinsed with clean water to remove any remaining Liquid Achieve SC Herbicide residues. Using a pressure washer and the addition of a detergent or Agral 90 to the rinse water will enhance removal of residues.
7. DO NOT APPLY within 50 m of non-crop areas. This includes fish-bearing waters, wetlands (potholes, sloughs etc.) and wildlife habitat (hedgerows, rights of way, etc.).

DIRECTIONS FOR USE
PEST(S):
Rate of application: 0.5 L Liquid Achieve SC Herbicide/ ha in 50 - 100 L of water/ ha. Add Turbocharge D Adjuvant or Intake Adjuvant at a rate of 0.5 L/100 L water (0.5% v/v). Under adverse conditions, such as dense weed population, late weed growth stage, or poor environmental conditions apply 1.0% V/V of Intake Adjuvant (10 L Intake Adjuvant /1000 L spray mixture).
Site (Crop):
For the following forage grasses grown for seed only:
- Seedling and established intermediate and crested wheatgrass, creeping red fescue, meadow and smooth bromegrass either underseeded to cereals or grown alone.
- For establishment of northern wheatgrass, western wheatgrass and slender wheatgrass.
Application Timing: Prior to tillering of the weeds (< 4 leaf stage)
Pre-Harvest Interval: NA
OTHER:
DO NOT APPLY BY AIR
Do not feed or graze forage crops, sufficient data are not available to support this use.
One application per season.
CAUTIONS:
Do not tank mix Liquid Achieve SC Herbicide with other herbicides, insecticides, fungicides, fertilizers, micronutrients or adjuvants other than those listed on this label, when applying to these forage grasses. Apply Liquid Achieve SC Herbicide prior to tillering of the weeds. Applications made after the weeds have tillered may result in unacceptable weed control due to poor crop competition compared to cereal crops. Crop injury or slight yield reductions may be expected following treatment in the year of establishment, however, the injury is transient and the crop will recover the following year.
BUFFER ZONES
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).
Method of Application: Field Sprayer
Buffer Zones (metres) Required for Protection of:
Terrestrial Habitat: 3
Method of Application: Aerial (fixed-wing)
Buffer Zones (metres) Required for Protection of:
Terrestrial Habitat: 100
Method of Application: Aerial (rotary-wing)
Buffer Zones (metres) Required for Protection of:
Terrestrial Habitat: 80
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.
NOTE: Applicators may recalculate a site-specific buffer zone by combining information on current weather conditions and spray 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 droplets smaller than the American Society of Agricultural Engineers (ASAE) [Fine or Medium or Coarse] classification.’ To access the Buffer Zone Calculator, please visit the Pest Management Regulatory Agency web site.
RESISTANCE MANAGEMENT RECOMMENDATIONS
For resistance management, Liquid Achieve SC Herbicide is a Group 1 herbicide. Any weed population may contain or develop plants naturally resistant to Liquid Achieve SC Herbicide and other Group 1 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 Liquid Achieve SC Herbicide or other Group 1 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 (weed-competitive 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.
For further information or to report suspected resistance, contact Dow AgroSciences Canada Inc. at 1-800-667-3852 or at www.dowagro.ca.
