DIRECTIONS FOR USE
Many methods of application are possible. The method chosen should be appropriate to the environmental, vegetative and other site conditions. Read all precaution statements before using this product. For more information or help, contact your local Corteva Agriscience Canada representative.

GENERAL USE PRECAUTIONS
Certain environmental conditions may increase the potential for herbicides to move in water, through the soil and enter an underlying aquifer1. These environmental conditions include:
• Soils that are very permeable (textures of sandy loam to sand) throughout the entire profile and which also have an underlying shallow aquifer.
• Soils containing sinkholes over limestone bedrock.
• Surfaces composed of severely fractured rock or unconsolidated gravels and underlaid with an aquifer.
The above conditions may permit direct movement of herbicides, including those containing picloram, to underlying aquifers.
Where any of the above environmental conditions exist, users are advised not to use either directed or broadcast foliage or aerial foliar application methods. Alternative cut surface methods of application should be chosen. These methods include tree injection, frill or girdle and cut stump treatments.
To help identify areas of concern, a Corteva Agriscience Canada representative can be contacted for additional information and assistance towards doing site inspections.
• Do not apply more than once per year.
• DO NOT apply this product directly to freshwater habitats (such as lakes, rivers, sloughs, ponds, prairie potholes, creeks, marshes, streams, reservoirs, irrigation ditches and wetlands), estuaries or marine habitats.
• DO NOT contaminate irrigation or drinking water supplies or aquatic habitats by cleaning of equipment or disposal of wastes.

Restricted Entry Interval (REI)
• For non-crop areas, do not enter or allow worker entry into treated areas until sprays have dried.
• For the use as a direct injection into treated plants: Restricted-entry interval is not required when
picloram is directly injected into treated plants.
Apply only when the potential for drift to areas of human habitation or areas of human activity (houses, cottages, schools and recreational areas) is minimal. Take into consideration wind speed, wind direction, temperature inversions, application equipment and sprayer settings.

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.

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 rotorspan.

Sensitive Plants
Most broadleaved plants are very sensitive to picloram. Care should be taken to avoid spraying desirable broadleaved plants during both growing and dormant periods. Aspect Herbicide, without a drift control additive or approved application system, should not be applied to the foliage of target vegetation near areas planted to crops such as beans (including soybeans), potatoes, tobacco, grapes, tomatoes, flowers, ornamental shrubs and trees or other desirable broadleaved crops. In addition, care should be taken to avoid contaminating soil in which sensitive crops will be grown. Clippings from vegetation which has been treated with Aspect Herbicide should not be used for composting or mulching, nor should the manure from animals grazing treated areas be used around susceptible plants, because picloram residues pass through the animal unchanged and are still herbicidally active.

BROADCAST GROUND APPLICATION
Directions for Use
Directed Leaf-Stem Applications With Single Nozzle Application Equipment
For control of woody plants, use 6.67 L of Aspect Herbicide in 1000 L of water and apply to woody plants after the foliage is fully developed. Maximum 1 application per year. The spray solution should thoroughly wet all plant parts including foliage and stems and should be applied when plants are actively growing to achieve the maximum control. Application made when the foliage has lost its normal green colour and vigour may not give satisfactory results.
For faster burndown of coniferous species use a recommended surfactant (such as Gateway Adjuvant, or Xiameter OFX-0309 Fluid, or any non-ionic surfactant) at the rate of 0.25% by volume (250 mL per 100 L of water). If maximum rainfastness is desired increase the rate to 0.375% (375 mL per 100 L of water).
The recommended surfactant should be added after the herbicide is thoroughly mixed. Agitate to thoroughly mix the water, surfactant and Aspect Herbicide. Apply soon after mixing. Do not prolong application for longer than 24 hours after mixing. See surfactant label for a full list of recommended rates.
Some surfactants require rates ranging from 0.2 to 1%.
When applying Aspect Herbicide with ground application equipment, the spray pressure at the nozzle should be no higher than is required for penetration of the target vegetation. The spray should always be directed toward the target, away from non-target, susceptible plants and no higher than the tops of the target plants. To aid in reducing spray drift, a nozzle and pressure should be selected which produces coarse spray droplets and minimizes production of fine droplets. Do not use high spray pressures in order to reach distant vegetation.

Broadcast Foliage Application
Woody Plant Control: Apply 11.5 L/ha of Aspect Herbicide in 200 L of total spray to control brush such as alder, birch, cedar, maple, pine, poplar, spruce and other species. Control of conifers or other hard-tocontrol brush species may be inconsistent. Maximum 1 application per year.
For faster burndown of coniferous species use a recommended surfactant (such as Gateway Adjuvant, or Xiameter OFX-0309 Fluid, or any non-ionic surfactant) at the rate of 0.25% by volume (250 mL per 100 L of water). If maximum rainfastness is desired increase the rate to 0.375% (375 mL per 100 L of water).
The recommended surfactant should be added after the herbicide is thoroughly mixed. Agitate to thoroughly mix the water, surfactant and Aspect Herbicide. Apply soon after mixing. Do not prolong application for longer than 24 hours after mixing. See surfactant label for a full list of recommended rates.
Some surfactants require rates ranging from 0.2 to 1%.
Broadleaved Weed Control: Apply 2.47 L/ha of Aspect Herbicide to control Canada thistle, dandelion and common yarrow. Apply 4.67 L/ha of Aspect Herbicide in 200 L of total spray volume to control broadleaved weeds such as sweet and red clover, wild carrot, common ragweed, goldenrod, dock, plantain, prickly lettuce, burdock, fleabane, vetch, leafy spurge♦ and toadflax♦. Apply in the spring or early summer after growth appears. Maximum 1 application per year.
♦For control of leafy spurge and toadflax under less than optimum growing conditions, use a recommended surfactant (such as Gateway Adjuvant, or Xiameter OFX-0309 Fluid, or any non-ionic surfactant) at the rate of 0.25% by volume (e.g., 250 mL per 100 L of water). If maximum rainfastness is desired increase the rate to 0.375% (375 mL per 100 L of water). The recommended surfactant should be added after the herbicide is thoroughly mixed. Agitate to thoroughly mix the water, surfactant and Aspect Herbicide. Apply soon after mixing. Do not prolong application for longer than 24 hours after mixing. See surfactant label for a full list of recommended rates. Some surfactants require rates ranging from 0.2 to 1%.
