GENERAL INFORMATION Rexade A Herbicide is a selective postemergence herbicide for the control of annual grasses and broadleaved weeds in spring wheat, durum wheat and winter wheat. Rexade A Herbicide is mixed with water and applied as a uniform broadcast spray. Rexade A Herbicide MUST be applied postemergence, to the main flush of actively growing weeds. Warm, moist growing conditions promote active weed growth and enhance the activity of Rexade A Herbicide 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. Rexade A Herbicide stops growth of susceptible weeds rapidly. However, typical symptoms (discolouration) of dying weeds may not be noticeable for 1 to 2 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 Rexade A Herbicide contains a Group 2 and a Group 4 mode of action herbicide. The Group 2 mode of action herbicide inhibits the production of the ALS enzyme in plants. This enzyme is essential for the production of certain amino acids required for plant growth. The Group 4 mode of action herbicide disrupts normal plant growth regulation resulting in death of susceptible plants. GENERAL USE PRECAUTIONS Sensitive Plants Do not apply Rexade A Herbicide 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. See Environmental Hazards section of the label. Crop Rotation Fields can be seeded 11 months following an application of Rexade A, with the following crops: spring barley, spring wheat, oats, canola, flax, brown and yellow mustard, canola quality Brassica juncea, field peas and soybean or fields can be summerfallowed. Sunflowers can be planted 10 months and lentils 22 months after application of Rexade A. This product has potential to leach. Do not apply excessive irrigation. Do not use in successive years at the same site. 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.

Spray Equipment Precaution Do not apply through any type of irrigation system. To Reduce Spray Drift: 1. Use nozzles delivering higher volumes and coarser droplets. 2. Use low pressures (200 to 275 kpa). 3. Use 100 L/ha of spray solution. 4. Spray when the wind velocity is 15 km/hr or less. 5. Spot treatments should only be applied with a calibrated boom to prevent over-application. 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. 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. Do not enter or allow worker entry into treated area for 12 hours following application or until sprays have dried.

For tank mixes, consult the labels of the tank-mix partners and observe the largest (most restrictive) buffer zone of the products involved in the tank mixture and apply using the coarsest spray (ASAE) category indicated on the labels for those tank mix partners. The spray drift 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 Rexade A Herbicide is a Group 2 and Group 4 herbicide. Any weed population may contain or develop plants naturally resistant to Rexade A Herbicide and other Group 2 and 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 Rexade A Herbicide or other Group 2 and 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 (weed-competitive crops or varieties) and other management practices. Monitor treated 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.

DIRECTIONS FOR USE GENERAL PRECAUTIONS This pesticide is not registered for the control of pests in aquatic systems. DO NOT use to control aquatic pests. DO NOT contaminate irrigation or drinking water suppliers or aquatic habitats by cleaning of equipment or disposal of wastes. Sensitive Plants Vegetables, flowers, grapes, fruit trees and other desirable plants are sensitive to 2,4-D even in minute quantities. Care should be taken to avoid spraying these types of plants or allowing spray mist to drift onto these plants during both their growing and dormant periods. At higher temperatures, vaporization may cause injury to susceptible plants growing nearby. This product may cause damage to lawns or pastures if applied before the grass is well established. In addition, most legumes may be damaged or killed. If applying this product using a handheld sprayer, do not directly spray or allow the spray to drift onto ornamentals or gardens. Do not spray roots of trees and ornamentals. When tank mixing, refer to the labels of the tank mix partner and follow all precautions and directions for use. 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. Observe buffer zones specified under BUFFER ZONES 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 rotor-span. Do not angle nozzles forward into the air-stream and do not increase the spray volume by increasing nozzle pressure. A spray thickening agent or drift retardant may be used with this product to air in reducing spray drift. Fixed and rotary-winged aerial applications to field crops should be made in a minimum of 30 L/ha total spray mixture. Do not use human flaggers. Avoid Spray Drift: Apply only when there is little or no hazard from spray drift. Small quantities of the spray, which may not be visible, may seriously injure susceptible crops and damage sensitive non-target habitat. A method must be used to detect air movement, lapse conditions or temperature inversions (stable air) such as the use of balloons or a continuous smoke column at or near the spray site or a smoke generator on the spray equipment. If the smoke develops into layers or indicates a potential for hazardous spray drift, do not spray. Apply only be 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.

DIRECTIONS FOR USE - CROP USE Ground Application Apply 50 to 200 L of spray solution per hectare depending on the type of application equipment used. Use sufficient water for even distribution. Apply when the weeds are actively growing. Follow DIRECTIONS FOR USE GENERAL PRECAUTIONS. Aerial Application (including fixed and rotary wing aircraft) Apply a minimum of 30 L of spray solution per hectare depending on the type of application system being used. Use boom pressures of 235 kpa or less. Avoid placing nozzles where spray will enter wing tip vortices. Follow DIRECTIONS FOR USE GENERAL PRECAUTIONS. To Prepare a Spray Add half the required amount of water to the spray tank, then the Rexade B Herbicide with agitation, and finally the balance of the water with continued agitation. WARNING: If preparing straight oil mixtures, do not let water get into the product or the finished mixture. NOTE: This product in water forms an emulsion, not a solution, which tends to separate on standing. Agitate to prevent such separation and ensure uniformity of spray mixture. Spot Treatment For knapsack application of Rexade B Herbicide for spot treatment of weeds such as thistles, mix 0.17 L of product in 10 L of water. Wet all foliage thoroughly. Selective Weed Control in Small Grains Weeds differ in their susceptibility to Rexade B Herbicide and not all types can be controlled satisfactorily in crops. The amount of Rexade B Herbicide to use will depend upon the susceptibility and whether the crops will tolerate this amount. See Table 1. Rexade B Herb E 32294 Dec16f SPECIMEN.docx Page 5

Wheat Spray from the 3-leaf expanded stage (15 cm tall) to just before the flag-leaf (shot-blade) stage. To avoid crop injury, do not treat during boot and flowering stages. Winter wheat should be treated in early spring, as soon as weeds appear and before the crop reaches the shot-blade stage.

Better control will result from 2 treatments applied one week apart at 0.51 L/ha Rexade B Herbicide. The higher rates may cause deformities and delayed maturity which will be offset by a higher relative yield from a less weedy crop. Pre-Harvest Interval Do not permit lactating dairy animals to graze fields within 7 days after application. Do not harvest forage or cut hay within 30 days after application. Withdraw meat animals from treated fields at least 3 days before slaughter. BUFFER ZONES Use of the following spray methods or equipment DO NOT require a buffer zone: hand-held or backpack sprayer and spot treatment. For application to rights-of-way, buffer zones for protection of sensitive terrestrial habitats are not required; however, the best available application strategies which minimize off-site drift, including meteorological conditions (e.g., wind direction, low wind speed) and spray equipment (e.g., coarse droplet sizes, minimizing height about canopy), should be used. Applicators must, however, observe the specified buffer zones for protection of sensitive aquatic habitats. 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) and estuarine/marine habitats.

Table 2: Buffer zones required to protect sensitive terrestrial and aquatic habitats. Buffer Zones (metres) Required for the Protection of: Freshwater Habitat Estuarine/Marine of Depths: Habitats of Method of application Crop Less than 1 m Greater than 1 m Less than 1 m Depths: Greater than 1 m Field Field crops (wheat) 1 0 1 0 1 sprayer Terrestrial habitat Aerial Field crops (wheat) Fixed wing Rotary Wing 1 0 1 0 45 1 0 1 0 40 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%. For tank mixes, consult the labels of the tank-mix partners and observe the largest (most restrictive) buffer zone of the products involved in the tank mixture and apply using the coarsest spray (ASAE) category indicated on the labels for those tank mix partners. RESISTANCE MANAGEMENT RECOMMENDATIONS For resistance management, Rexade B Herbicide is a Group 4 herbicide. Any weed population may contain or develop plants naturally resistant to Rexade B 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 Rexade B 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 (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. Rexade B Herb E 32294 Dec16f SPECIMEN.docx Page 7
