PRODUCT INFORMATION
Attain Herbicide Tank-Mix is a selective postemergence herbicide for the control of broadleaved weeds in spring wheat, durum wheat, and spring barley (not underseeded to legumes). Attain Herbicide Tank-Mix provides control of hard-to-kill annual broadleaved weeds such as cleavers and kochia (including populations resistant to Group 2 herbicides). Attain Herbicide Tank-Mix mix will also provide suppression of common chickweed. The components of Attain Herbicide Tank-Mix move within the plant to control exposed and underground plant tissues. It mimics naturally occurring plant hormones which control weeds by disrupting normal plant growth patterns. Symptoms of effect include epinasty (twisting of the stems) and swollen nodes.

USE PRECAUTIONS


READ THE ENTIRE LABEL BEFORE USE. FAILURE TO FOLLOW LABEL INSTRUCTIONS MAY RESULT IN ERRATIC WEED CONTROL OR CROP DAMAGE. DO NOT APPLY TO CROPS UNDERSEEDED WITH LEGUMES.

- To minimize spray drift to non-target areas:
1. Do not use nozzles that produce a fine spray droplet.
2. Minimize drift by using sufficient spray volume to ensure coverage with large droplet size sprays.
3. Keep ground-driven spray booms as low as possible above the target surface.
4. Spray when wind is less than 8 km/hr.
5. 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.

Extreme growing conditions such as drought or near freezing temperatures prior to, at and following time of application may reduce weed control and increase the risk of crop injury at all stages of growth.
- Wet foliage at the time of application may result in reduced weed control.
- Over-application may result in crop injury.
- Make only 1 application per year.
- Do not apply through any type of irrigation system.
- DO NOT APPLY BY AIR.

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.

Restricted Entry Interval (REI)
All crops—12-hour REI

Sprayer Clean-up
Sprayers used to apply Attain Herbicide Tank-Mix should not be used to apply other pesticides to sensitive crops without a thorough cleaning. Do not contaminate irrigation or drinking water when leaning the sprayer. Spray equipment should be cleaned after use by the following procedure:
1. Drain the sprayer tank.
2. Hose down the interior surfaces of the tank. Flush tank, hoses, boom and nozzles with clean water for 10 minutes. Fill the tank with water and recirculate for 15 minutes. Spray part of the mixture through the hoses, boom and nozzles and drain the tank.
3. Remove the nozzles and screens and clean them separately.
4. If the spray equipment will be used on other crops other than cereal crops, repeat 1 and 2 again and thoroughly wash the spray mixture from the outside of the spray tank and the boom.

SENSITIVE PLANTS
Do not apply Attain Herbicide Tank-Mix directly to, or otherwise permit it to come in direct contact with susceptible crops or desirable plants including alfalfa, edible beans, canola, flowers and ornamentals, lentil, lettuce, peas, potatoes, radishes, soybeans, sugar beets, sunflowers, tomatoes or tobacco.

ROTATIONAL CROP RESTRICTIONS
Fields previously treated with Attain Herbicide Tank-Mix can be seeded the following year to barley, canola, flax, forage grasses, lentils, mustard, oats, peas, rye and wheat or fields can be summerfallowed.

PRE-HARVEST/GRAZING INTERVALS
1. Do not permit lactating dairy animals to graze fields within 7 days after application.
2. Do not harvest forage or cut hay within 30 days after application.
3. Withdraw meat animals from treated fields at least 3 days before slaughter.
4. Do not harvest the treated mature crop within 60 days after application.

Tank Mixtures
Do not apply this product with any other additive, pesticide or fertilizer except as specifically recommended on this label. 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.

DIRECTIONS FOR USE

Crops Registered:
spring wheat, durum wheat, spring barley

Timing of Application
Apply postemergence when weeds are in the seedling stage (2-4 leaf), and actively growing, and when spring wheat and spring barley are in the 4-leaf to flag-leaf stage. Application before the 4-leaf stage of wheat and barley may cause severe twisting of leaves and leaf, stem and head deformities which may reduce yield up to 10%. Do not apply later than the flag-leaf stage. Maximum 1 application per year.

Rates of Application
I. Low Rate: To control the following weeds apply a uniform spray containing 0.45 L/ha Attain A and 0.75 L/ha Attain B in a minimum of 100 L of water per hectare to thoroughly cover the weeds. The contents of this carton will treat 21 hectares.
II. High Rate: To control the above weeds plus the following additional weeds apply a uniform spray containing 0.6 L/ha of Attain A and 1.0 L/ha of Attain B in a minimum of 100 L of water per hectare to thoroughly cover the weeds. The contents of this carton will treat 16 hectares.
NOTE: Attain Herbicide Tank-Mix activity is influenced by weather conditions. Optimum activity requires active crop and weed growth. The temperature range for optimum activity is 12 C to 24 C. Reduced activity will occur when temperatures are below 8 C or above 27 C. Frost before application (3 days) or shortly after (3 days) may reduce weed control and crop tolerance. Weed control may be reduced during stress conditions, e.g. drought, heat or cold stress, or if weeds have initiated flowering, or if heavy infestations exist.

Mixing Instructions
1. Fill sprayer tank 1/2 full of water.
2. Start sprayer tank agitation.
3. Add the required number of jugs of Attain A.
4. Add the required number of jugs of Attain B.
5. Complete filling the sprayer tank with sufficient water to spray 100 L of spray mixture per hectare.
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 as listed.

Spray Application
Apply Attain Herbicide Tank-Mix in sufficient spray volume to provide uniform coverage using properly calibrated ground equipment. A total spray volume of 100 L/ha using low pressure (200 to 275 kPa) application is recommended. Maintain sufficient agitation in the spray tank during mixing and spraying to ensure a uniform spray mixture.

TANK MIXES WITH ATTAIN HERBICIDE TANK-MIX FOR ANNUAL GRASS CONTROL
Tank mixtures of Attain Herbicide Tank-Mix with other herbicides will provide control of additional weeds.
Read all precautions, minimal interval to harvest and directions for use on the Attain Herbicide Tank-Mix and tank-mix partner labels and follow the more stringent of the two.

BUFFER ZONES TO PROTECT SENSITIVE HABITATS
A 15 metre buffer zone is 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.
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%.
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, Attain HerbicideTank-Mix is a Group 4 herbicide. Any weed population may contain or develop plants naturally resistant to Attain Herbicide Tank-Mix 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 Attain Herbicide Tank-Mix 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.
