GENERAL INFORMATION
Baseline Herbicide Tank-Mix is a post emergent herbicide for the control of annual broadleaved weeds including wild oats and green foxtail in spring wheat, durum wheat and spring barley (not underseeded with legumes). Baseline Herbicide Tank-Mix is mixed with water and applied as a uniform broadcast spray.

MODE OF ACTION
Baseline Herbicide Tank-Mix is a systemic auxin-type herbicide and moves within the plant for control of exposed and underground plant tissues. The product controls weeds by disrupting normal plant growth patterns. Symptoms of weeds include epinasty (twisting of the stems) and swollen nodes.

GENERAL USE PRECAUTIONS


Sensitive Plants

Do not apply Baseline 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, lentils, lettuce, peas, potatoes, radishes, soybeans, sugar beets, sunflowers, tomatoes or tobacco.

Non-Target Sites
Do not apply where proximity of susceptible crops or other desirable plants is likely to result in exposure to spray or spray drift.

Crop Rotation
Fields previously treated with Baseline Herbicide Tank-Mix can be seeded the following year to barley, canola, flax, forage grasses, lentils, mustard, oats, peas, rye or wheat or fields can be summerfallowed.

Pre-Harvest Grazing Intervals
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.

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.

Spray Equipment Precaution

Do not apply through any type of irrigation system.

To Reduce Spray Drift:

Use nozzles delivering higher volumes and coarser droplets.
Use low pressures (275 kPa).
Use 100 L/ha of spray solution.
Spray when the wind velocity is 15 km/hr or less.
Spot treatments should only be applied with a calibrated boom to prevent over-application.

To Reduce Runoff from Treated Areas:

To reduce runoff from treated areas into aquatic habitats, consider the characteristics and conditions of the site before treatment. Site characteristics and conditions that may lead to runoff include, but are not limited to: heavy rainfall, moderate to steep slope, bare soil, poorly draining soil (e.g. soils that are compacted, fine textured, or low in organic matter such as clay). Avoid application of this product when heavy rain is forecast. Contamination of aquatic areas as a result of runoff may be reduced by including a vegetative strip (buffer zone) between the treated area and the edge of the water body.

Equipment Clean-Up

Equipment used to apply Baseline Herbicide Tank-Mix should not be used to apply other pesticides to sensitive crops without thorough cleaning. Contact your Baseline Herbicide Tank-Mix dealer for detailed equipment cleaning procedures.

DIRECTIONS FOR USE
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.

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.

Application Directions

Apply Baseline Herbicide Tank-Mix to actively growing weeds, and to actively growing wheat and barley (from the 2-leaf crop growth stage up to and including initiation of stem elongation) for best results. Weeds emerging after application of Baseline Herbicide Tank-Mix will not be controlled.
For control of listed weeds, apply a uniform spray containing 0.5 L/ha of Baseline A Herbicide and 0.6L/ha of Baseline B Herbicide in 100 L of water per hectare to thoroughly cover the weeds. Baseline Adjuvant must also be added at a rate of 0.5 L per 100 L of water. Only weeds emerged at the time of treatment will be controlled. Best results are obtained from applications made to seedling weeds.
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. Use of this tank-mix under adverse conditions may increase severity of crop injury; crops under stress from foliar diseases or low fertility are more susceptible to injury.

Mixing Instructions
1. Only use sprayers in good running condition with high agitation. Ensure the sprayer and pre-mix tank is cleaned according to instructions on the label of the product used prior to Baseline Herbicide Tank-Mix. 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 with clean water, and engage agitator. Agitation must be continued throughout the entire mixing and spraying procedure.
3. When the sprayer is three quarters full of water, add Baseline A Herbicide. If more than one container of Baseline A Herbicide is to be used, add all Baseline A Herbicide containers prior to adding Baseline B Herbicide.
4. Add Baseline B Herbicide next. If more than one container of Baseline B Herbicide is to be used, add all Baseline B Herbicide containers prior to adding Baseline Adjuvant.
5. Lastly, add the required amount of Baseline Adjuvant and then continue to fill tank to desired level with water.
6. The herbicidal activity of Baseline Herbicide Tank-Mix can be negatively affected in 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 L 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.

TANK-MIX COMBINATIONS WITH BASELINE HERBICIDE TANK-MIX
Baseline Herbicide Tank-Mix can be mixed with other herbicides to customize weed control to the field you are treating. To control additional broadleaved weeds, tank-mix Baseline Herbicide Tank-Mix with up to 560 g ae/ha of either 2,4-D Ester or MCPA Ester (equivalent to 1.0 L/ha of 2,4-D LV600 or 1.12 L/ha of MCPA LV500) or 1.5 to 2.0 L/ha Curtail (1) M Herbicide. Refer to tank-mix partner labels for rates and weeds controlled, and for more restrictions, information on precautions, and additional directions for use.

GROUND SPRAYING INSTRUCTIONS:
1. Apply in a spray volume of 100 L/ha at a pressure of 275 kPa to ensure proper dispersion, spraying characteristics and performance of Baseline Herbicide Tank-Mix.
2. Flat fan nozzles of 80 or 110 are recommended for optimum coverage. Do not use floodjet nozzles or controlled droplet application equipment. Nozzles may be angled forward 45 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. Baseline Herbicide Tank- Mix 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 Baseline Herbicide Tank-Mix residues. Using a pressure washer and the addition of a detergent 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.

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).
When a tank mixture is used, consult the labels of the tank-mix partners and observe the largest (mostrestrictive) buffer zone of the products involved in the tank mixture.

(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%.

When a tank mixture is used, consult the labels of the tank-mix partners and observe the largest (mostrestrictive) buffer zone of the products involved in the tank mixture. 

RESISTANCE MANAGEMENT RECOMMENDATIONS
For resistance management, please note that Baseline Herbicide Tank-Mix is both a Group 1 and a Group 4 herbicide. Any weed population may contain plants naturally resistant to Group 1 and/or Group 4 herbicides. The resistant biotypes may dominate the weed population if these herbicides are used repeatedly in the same fields. Other resistance mechanisms that are not linked to site of action, but specific for individual chemicals, such as enhanced metabolism, may also exist. Appropriate resistancemanagement strategies should be followed.
To delay herbicide resistance:
Where possible, rotate the use of Baseline Herbicide Tank-Mix or other Group 1 and 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.
