GENERAL INFORMATION
Simplicity is a selective postemergence herbicide for the control of wild oats and certain broadleaved weeds in spring wheat, durum wheat and winter wheat not underseeded with legumes. Simplicity is mixed with water and applied as a uniform broadcast spray. It is non-corrosive, nonflammable, and nonvolatile.
Simplicity must be applied early postemergence, to the main flush of actively growing wild oats and broadleaved weeds. Conditions favouring active weed growth enhance the activity of Simplicity by allowing maximum foliar uptake and contact activity. Weeds hardened off by cold weather or drought stress may not be adequately controlled or suppressed and re-growth may occur. For best results, ensure thorough spray coverage of target weeds. See “DIRECTIONS FOR USE” section of this label for complete use details.
Simplicity stops growth of susceptible weeds rapidly. However, typical symptoms (discolouration) of dying weeds may not be noticeable for 1 to 3 weeks after application, depending upon growing conditions and weed susceptibility. Degree of control and duration of effect are dependent on weed sensitivity, weed size, crop competition, growing conditions at and following treatment, and spray coverage.
MODE OF ACTION
Simplicity inhibits the production of the ALS enzyme in plants. This enzyme is essential for the production of certain amino acids which are essential for plant growth. Simplicity is a Group 2 mode of action herbicide.

GENERAL USE PRECAUTIONS


Non-Target Sites

Do not apply where proximity of susceptible crops (e.g. canola and legumes) or other desirable plants is likely to result in exposure to spray or spray drift. See Environmental Hazards section of the label.

Crop Rotation

Fields previously treated with Simplicity can be seeded 11 months following an application of Simplicity, with the following crops: barley, brown mustard, canola, dry bean (of the species Phaseolus vulgaris), flax, canola quality Brassica juncea, lentils, oats, field peas, chickpea, spring wheat, soybean and yellow mustard or fields can be summerfallowed. Fields previously treated with Simplicity can be seeded 10 months following an application of Simplicity with the following crops: sunflower and potatoes.

Tank Mixtures

In some cases, tank mixing a pest control product with another pest control product or a fertilizer can result in biological effects that could include, but are not limited to: reduced pest efficacy or increased host crop injury. The user should contact Dow AgroSciences Canada Inc. at 1-800-667-3852 or www.dowagro.ca for information before mixing any pesticide or fertilizer that is not specifically recommended on this label. The user assumes the risk of losses that result from the use of tank mixes that do not appear on this label or that are not specifically recommended by Dow AgroSciences Canada Inc.

Spray Equipment Precaution

Do not apply through any type of irrigation system.

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 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.

SIMPLICITY ALONE


Application Directions - Spring Wheat, Durum wheat

Apply Simplicity at a rate of 500 mL per hectare. Add non-ionic surfactant (Agral 90, AgSurf or Surf 92) at 0.25 v/v (0.25 L per 100 L of spray solution). Apply using aerial equipment or ground equipment that will assure uniform coverage. See table below for weeds species controlled. Simplicity will control only emerged weeds. Weeds that germinate after application will not be controlled.

Weeds Controlled or Suppressed with Simplicity

Weeds Controlled:
barnyard grass (1-5 leaf), brome Japanese (1-6 leaf), canola volunteer† (1-6 leaf), chickweed common (up to 10 cm), cleavers (up to 6 whorl), corn spurry (up to 2 whorl stage, <10 cm in height), cow cockle (up to 8 leaf), flixweed (up to 10 cm), foxtail yellow (1-5 leaf), hemp nettle (1-8 leaf), oats, wild (up to 4 leaf, 2 tiller), pigweed red-root (1-8 leaf ), round-leaved mallow (up to 6 leaf stage, <10 cm in size), smartweed (lady’s-thumb, 1-5 leaf), shepherd’s purse (up to 30 cm tall), stinkweed (up to 30 cm tall)
†will not control volunteer Imidazolinone-tolerant canola
Weeds Suppressed:
brome downy (2-6 leaf, 4 tillers), dandelion (seedlings and over-wintered rosettes less than or equal to 20 cm), foxtail green (1-5 leaf), wild buckwheat (1-4 leaf), Canada thistle (up to 30 cm tall, prebud), Russian thistle (up to 10 cm tall)

Application Timing

Apply to actively growing wheat from the 3 leaf stage to before the flag leaf stage. Apply when weeds are actively growing: grass weeds up to the 4 leaf, 2 tiller stage and broadleaved weeds as indicated in the table above. Only weeds emerged at the time of treatment will be controlled. Best results are obtained from applications made to seedling weeds. Extreme growing conditions such as drought or near freezing temperature prior to, at or following time of application may reduce weed control and increase the risk of crop injury at all stages of growth. Under conditions of low crop and high weed density, control may be reduced.

Application Directions - Winter Wheat (Fall or Spring Application) for Downy Brome

Simplicity applied in the fall will provide control of downy brome while a spring application will provide suppression. Apply Simplicity at a rate of 500 mL per hectare. Add BASF Assist Oil Concentrate at 0.8% v/v (0.8 L/100 L of spray mixture) or Merge Adjuvant at 0.5% v/v (0.5 L/100 L of spray mixture; spring application only). Apply using aerial equipment or ground equipment that will assure uniform coverage. In addition to suppression of downy brome when applied in the spring Simplicity will also control/suppress weeds listed. Simplicity will control only emerged weeds. Weeds that germinate after application will not be controlled.

Application Timing

Apply in the fall when winter wheat is in the 1-3 leaf stage or in the spring when winter wheat is in the 2-7 leaf, 4 tiller stage. For fall applications, apply when downy brome is actively growing at the 1 to 3 leaf stage; for spring applications, apply when weeds are actively growing at the stages indicated. Only weeds emerged at the time of treatment will be controlled. Best results are obtained from applications made to seedling weeds. Extreme growing conditions such as drought or near freezing temperature prior to, at or following time of application may reduce weed control and increase the risk of crop injury at all stages of growth. Under conditions of low crop and high weed density, control may be reduced.
Occasionally slight yellowing or height reduction may be observed in the treated crop. These transient symptoms disappear within 14 days with no reduction to yield. Do not apply to crops suffering from drought, nutrient deficiency or exposed to frost or other agronomic factors affecting plant growth.
If foliage is wet at the time of application control may be decreased. Applications of Simplicity are rainfast within 2 hours after application.

Mixing Instructions

1. Fill sprayer tank 1/2 full of water.
2. Start sprayer tank agitation.
3. Add the required amount of Simplicity
4. Fill the sprayer tank with sufficient water to spray 30-100 L of spray mixture per hectare.
5. Add non-ionic surfactant (Agral 90, AgSurf or Surf 92) at 0.25 v/v (0.25 L per 100 L of spray solution)
6. Follow sprayer directions and precautions as outlined above, especially when applying next to sensitive crops (e.g. canola and legumes).
7. Follow sprayer clean-up directions.

Pre-harvest/Grazing Intervals

Livestock may be grazed on treated crops 7 days following application. Do not harvest the treated crop within 60 days after application.

APPLICATION INSTRUCTIONS (GROUND AND AERIAL APPLICATIONS)


(1) Ground Application (Simplicity applied alone and with all tank mix partners)

Using ground equipment, apply Simplicity alone or with tank mix partners as a broadcast treatment. Apply Simplicity alone at the recommended rates in a spray volume of 30-100 L water / ha. When tank mixing refer to the label of the tank mix partner label for additional instructions, water volumes, precautions and weeds controlled.

(2) Aerial Application


Directions for Use

Do not use human flaggers.

Use Simplicity alone or in tank mix with either MCPA Ester or Buctril M as a broadcast treatment by air. Apply the recommended rates of Simplicity and either MCPA Ester or Buctril M as indicated above. Apply in a minimum spray volume of 30 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.

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), and sensitive freshwater habitats (such as lakes, rivers, sloughs, ponds, prairie potholes, creeks, marshes, streams, reservoirs and wetlands).

Method of application: Field sprayer

Crop: Spring wheat, durum wheat, winter wheat
Buffer Zones (metres) Required for the Protection of:
Freshwater Habitat of Depths: 1
Terrestrial habitat: 2

Method of application: Aerial

Crop: Spring wheat, durum wheat, winter wheat (Fixed wing)
Buffer Zones (metres) Required for the Protection of:
Freshwater Habitat: 1
Terrestrial habitat: 70

Crop: Spring wheat, durum wheat, winter wheat (Rotary wing)
Buffer Zones (metres) Required for the Protection of:
Freshwater Habitat: 1
Terrestrial habitat: 60

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. Apply using the coarsest spray (ASAE) category indicated on the label for those tank-mix partners.
The buffer zones for this product can be modified based on weather conditions and spray equipment configuration by accessing the Buffer Zone Calculator on the Pest Management Regulatory Agency web site.

RESISTANCE MANAGEMENT RECOMMENDATIONS

For resistance management, Simplicity is a Group 2 herbicide. Any weed population may contain or develop plants naturally resistant to Simplicity and other Group 2 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 Simplicity or other Group 2 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 crop 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 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.
