GENERAL INFORMATION 

Chateau Herbicide WDG provides residual control of susceptible weeds in dry bulb onion, potato (Western Canada only), sweet potato, pome fruit (apple and pear), grape, strawberry, established mint (peppermint and spearmint), highbush blueberry, lowbush blueberry, stone fruit (peach, cherry, nectarine, plum, and apricot), asparagus, nut trees (including almond, beech nut, bur oak, butternut, cashew, chestnut, chinquapin, filbert [hazelnut], ginko, heart nut, hickory nut, Japanese horse-chestnut, monkey puzzle, pecan, pine nuts, walnut [black and English], yellowhorn, cultivars and varieties and/or hybrids of these), field pepper, celery and to maintain bare ground non-crop areas on farms when used in accordance with this label. Chateau Herbicide WDG is effective as a preemergence herbicide, for control of selected grass and broadleaf weeds. Chateau Herbicide WDG controls weeds by inhibiting protoporphyrinogen oxidase, an essential enzyme required by plants for chlorophyll biosynthesis. Seedling weeds are controlled preemergence when exposed to sunlight following contact with the soil applied herbicide. Preemergence weed control with Chateau Herbicide WDG is most effective when applied to clean, weed-free soil surfaces. Disturbing soil surfaces may reduce herbicide efficacy. Chateau Herbicide WDG offers residual control of susceptible grass and broadleaf weeds listed on this label and assists in the control of acetolactate synthase (ALS) resistant weeds.

Tank Mix Restrictions
Always read and follow label directions for all tank mix products before using. The most restrictive labeling of any tank mix partner must be followed. Do not tank mix Chateau Herbicide WDG, or use in the same field, with flufenacet, metolachlor or s-metolachlor, dimethanamid or dimethanamid-p, alachlor, or acetochlor, as crop injury may occur.

Rotational Restrictions
The following rotational crops may be planted after applying Chateau Herbicide WDG at the listed rate. Planting earlier than the recommended rotational interval may result in crop injury.

GENERAL DIRECTIONS FOR USE

SPRAYER AND APPLICATION INFORMATION
Apply using ground application equipment only. Before applying Chateau Herbicide WDG, start with clean, well maintained application equipment. Nozzles should be uniformly spaced on boom and frequently checked for accuracy. For broadcast application, apply Chateau Herbicide WDG with ground equipment using standard commercial sprayers equipped with nozzles designed to deliver the desired spray pressure and spray volume. When banding, use proportionately less water and Chateau Herbicide WDG per hectare. Equipment with Chateau Herbicide WDG residues remaining in the system may result in crop injury to the subsequently treated crop. Spray equipment used to apply Chateau Herbicide WDG should not be used to apply other materials to any plant foliage. Spray equipment must be cleaned each day following Chateau Herbicide WDG application. After Chateau Herbicide WDG is applied, the following steps must be used to clean the spray equipment:
1. Completely drain the spray tank, rinse the sprayer thoroughly, including the inside and outside of the tank and all in-line screens. Fill the spray tank with clean water and flush all hoses, booms, screens and nozzles.
2. Top off tank, add 4 L of 3% household ammonia for every 400 L of water, circulate through sprayer for 5 minutes, and then flush all hoses, booms, screens and nozzles for a minimum of 15 minutes.
3. Drain tank completely.
4. Add enough clean water to the spray tank to allow all hoses, booms, screens and nozzles to be flushed for 3 minutes.
5. Remove all nozzles and screens and rinse them with clean water.
6. Do not contaminate water, food or feed by cleaning of equipment.

MIXING INSTRUCTIONS
1. Fill clean spray tank 1/2 to 2/3 of desired level with clean water. Engage gentle agitation.
2. While agitating, slowly add Chateau Herbicide WDG to the spray tank. Agitation should create a rippling or rolling action on the water surface.
3. If tank mixing Chateau Herbicide WDG with other labelled herbicides, add water soluble bags first, followed by dry formulations, flowables, emulsifiable concentrates and then solutions. Prepare no more spray mixture than is required for the immediate spray operation.
4. Add adjuvants or surfactants, if recommended.
5. Fill spray tank to desired level with water. Agitation should continue until spray solution has been applied.
6. Mix only the amount of spray solution that can be applied the day of mixing. Chateau Herbicide WDG should be applied within 6 hours of mixing.
As 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 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 S572.1) medium classification. Boom height must be 60 cm or less above the crop or ground.

DO NOT apply by air.

Use caution when applying under circumstances where possible drift to unprotected persons or food, forage or other plantings that might be damaged or crops thereof rendered unfit for sale, use or consumption can occur. Use the largest droplet size consistent with acceptable efficacy. Formation of very small droplets may be minimized by appropriate nozzle selection, by orienting nozzles away from the air stream as much pressure. Make application when the wind velocity favours on-target product deposition. Do not make applications during temperature inversions. Inversions are characterized by stable air and increasing temperatures with increasing distance above the ground. Mist or fog may indicate the presence of an inversion in humid areas. Where permissible by local regulations, the applicator may detect the presence of an inversion by producing smoke and observing a smoke layer near the ground surface. Low humidity and high temperatures increase the evaporation rate of spray droplets and therefore the likelihood of increased spray drift. Avoid spraying during conditions of low humidity and/or high temperatures. All ground application equipment must be properly maintained and calibrated using appropriate carriers.

BUFFER ZONES:
Use of the following spray methods or equipment DO NOT require a buffer zone: handheld or backpack sprayer and spot treatment, or low-clearance hooded or shielded sprayers that ensure spray drift does not come in contact with orchard crop fruit or foliage. 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 above canopy), should be used. Applicators must, however, observe the specified buffer zones for protection of sensitive terrestrial and 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.

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.

DIRECTIONS FOR USE IN ASPARAGUS
Crop injury may occur from applications made to poorly drained soils and/or applications made under cool, wet conditions. Severe crop injury will result when soils are flooded following applications of Chateau Herbicide WDG. Risk of crop injury can be minimized by using on well-drained soils. Treated soil that is splashed onto newly emerged crops may result in temporary crop injury. Moisture is necessary to activate Chateau Herbicide WDG in soil for residual weed control. Dry weather following applications of Chateau Herbicide WDG may reduce effectiveness. However, when adequate moisture is received after dry conditions, Chateau Herbicide WDG will control susceptible germinating weeds listed on this label. Chateau Herbicide WDG may not control weeds that germinate after application but before an activating rainfall/irrigation or weeds that germinate through cracks resulting from dry soil. When adequate moisture is not received after a Chateau Herbicide WDG application, weed control may be improved by irrigation with at least ½ to 1 cm of water. Residual weed control will be reduced if there is mechanical incorporation into the soil or if emerged weeds are controlled by cultivation.
Apply only once per growing season.
Do not apply to fine-textured soils.
Apply prior to weed emergence.
Apply only to dormant asparagus established for at least one year. Application to non-dormant asparagus may result in unacceptable crop injury.
Applications should be made no sooner than two weeks prior to emergence of spears and must be sprinkler or rainfall activated with 1-2 cm of water or some scoring may result.
Do not work soil within 60 days prior to application in the spring. Soil can be worked after spear harvest in preparation for Chateau Herbicide WDG application prior to fern emergence. Treated soil that is splashed onto the ferns may result in spotting
Use an appropriate water volume to ensure thorough coverage.
Chateau Herbicide WDG may cause injury if spears emerge before the application has been activated with water. Ensure an irrigation or rain event occurs between application and spear emergence.
Do not apply by air. Apply using ground application equipment only.

DIRECTIONS FOR USE IN STONE FRUIT (PEACH, CHERRY, NECTARINE, PLUM, APRICOT)
Chateau Herbicide WDG offers residual control of susceptible broadleaf and grass weeds listed on this label and assists in the control of acetolactate synthase (ALS) resistant weeds. The length of residual control is dependent on the application rate as well as on rainfall and temperature conditions. Length of residual control will decrease as temperature and precipitation increase and on soils of high organic matter and/or high clay content. Crop injury may occur from applications made to poorly drained soils and/or applications made under cool, wet conditions. Risk of crop injury can be minimized by using on welldrained soils. Moisture is necessary to activate Chateau Herbicide WDG in soil for residual weed control. Dry weather following applications of Chateau Herbicide WDG may reduce effectiveness. However, when adequate moisture is received after dry conditions, Chateau Herbicide WDG will control susceptible germinating weeds. Chateau Herbicide WDG may not control weeds that germinate after application but before an activating rainfall/irrigation or weeds that germinate through cracks resulting from dry soil. When adequate moisture is not received after a Chateau Herbicide WDG application, weed control may be improved by irrigation with at least ½ to 1 cm of water. Weed control will be reduced if there is mechanical incorporation into the soil or if emerged weeds are controlled by cultivation.
Do not apply to fine-textured soils.
Do not apply to trees established less than two years, unless protected from spray contact by non-porous wraps, grow tubes or waxed containers.
Avoid direct or indirect spray contact to foliage and green bark.

Do not apply to powdery soils or soils that are susceptible to wind displacement unless irrigation can be applied immediately after application.
Do not apply by air. Apply using ground application equipment only.

RESISTANCE MANAGEMENT RECOMMENDATIONS 
For resistance management Chateau Herbicide WDG contains a Group 14 herbicide. Any weed population may contain or develop plants naturally resistant to Chateau Herbicide WDG and other Group 14 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 Chateau Herbicide WDG or other Group 14 herbicides with different herbicide groups that control the same weeds in the 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 advisor for any additional pesticide resistance-management and/or or integrated weed-management recommendations for specific crops and weed biotypes.
