ENVIRONMENTAL CONDITIONS AND BIOLOGICAL PERFORMANCE
Preemergence Application (Conventional Tillage)
Important: 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 well drained soils, planting at least 1.5 inches deep, using high quality seed, and completely covering seeds with soil prior to preemergence applications.
Treated soil that is splashed onto newly emerged crops may result in temporary crop injury.
Moisture is necessary to activate Chateau WDG in soil for residual weed control. Dry weather following applications of Chateau WDG may reduce effectiveness. However, when adequate moisture is received after dry conditions, Chateau WDG will control susceptible germinating weeds. Chateau 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 WDG application, weed control may be improved by irrigation with at least 1/4 inch of water. If emerged weeds are controlled by cultivation, residual weed control will be reduced.
For best results, Chateau WDG should be applied as part of a burndown program to actively growing weeds. Applying Chateau WDG under conditions that do not promote active weed growth will reduce herbicide effectiveness. Do not apply Chateau WDG when weeds are under stress due to drought, excessive water, extremes in temperature, disease or low humidity. Weeds under stress tend to become less susceptible to herbicidal action. Chateau WDG is most effective when applied under warm sunny conditions.
Reduced residual weed control may occur when burndown applications are made to fields where heavy crop and/or weed residue exist.
Chateau WDG should only be applied to healthy crops labeled for postemergence use. Do not apply Chateau WDG to crops that have been weakened by disease, drought, flooding, excessive fertilization, soil salts, previously applied pesticides, nematodes, insects or winter injury.
Chateau WDG is rainfast one hour after application. Applications should not be made if rain is expected within one hour of application or postemergence efficacy may be reduced.
Application of Chateau WDG to soils with high organic matter and/or high clay content may require higher dosages than soils with low organic matter and/or low clay content. Application to cloddy seedbeds can result in reduced weed control.
Residual Weed Control (Including Preemergence
Applications or Applications as Part of a Fall or Spring Burndown and Fallow Seedbed Program)
Based upon soil characteristics (organic matter content and texture), the most difficult to control weed species being targeted and the crop being grown, select the proper Chateau WDG dosage from the rate range tables contained in the label.
CARRIER VOLUME AND SPRAY PRESSURE
(Ground Equipment only. See Information for Aerial Equipment under “AERIAL APPLICATION”.)
Preemergence Application (Conventional Tillage)
To ensure uniform coverage, use 10 to 30 gals. of spray solution per acre for conventional tillage applications. Nozzle selection should meet manufacturer's gallonage and pressure recommendations for preemergence herbicide application.
Burndown Application (Prior to Crop Emergence)
To ensure thorough coverage in burndown applications, use 15 to 50 gals. spray solution per acre. Use 20 to 50 gals. per acre if dense vegetation or heavy crop residue is present. Nozzle selection should meet manufacturer's gallonage and pressure recommendations for postemergence herbicide application.
Postemergence Application (Emerged Crop)
To ensure thorough coverage in burndown applications, use 15 to 30 gals. spray solution per acre. Use 20 to 30 gals. per acre if dense vegetation or heavy crop residue is present. Nozzle selection should meet manufacturer's gallonage and pressure recommendations for postemergence herbicide application.
Apply Chateau WDG, and Chateau WDG tank mixes, with ground equipment using standard commercial sprayers equipped with flat fan or flood nozzles (preemergence applications only) designed to deliver the desired spray pressure and spray volume.
When banding, use proportionately less water and Chateau WDG per acre. The rate of Chateau WDG required per acre, when applied as a banded application.
Spray drift away from the site of application may cause damage to non-target vegetation. To minimize drift, apply the largest droplet size consistent with uniform coverage and satisfactory weed control.
FALL BURNDOWN PROGRAMS IN FIELDS TO BE PLANTED TO BARLEY, FIELD PEA, FLAX, LENTIL, SAFFLOWER, SUNFLOWER AND SPRING WHEAT (Preemergence to Crop)
GENERAL RESTRICTIONS AND LIMITATIONS
- Do not apply to frozen or snow covered soil.
- Do not perform any tillage operation after application or residual weed control will be reduced.
- Chateau WDG can be mixed with 2,4-D and/or glyphosate formulations labeled for burndown programs (preemergence to crop) in accordance with the most restrictive label limitations and precautions. Labeled application rates can not be exceeded. Do not mix Chateau WDG with any product containing a label prohibition against such mixing.

SPECIAL CROP USE RESTRICTIONS
The pesticide applicator, the producer of the crop, and the seed conditioner must be aware that if Chateau Herbicide WDG is applied to alfalfa grown for seed, that the seed and seed screenings are deemed nonfeed/nonfood items by the Oregon Department of Agriculture, and are regulated by Oregon Administrative Rule (OAR) 603-057-0535, Pesticide Use On Crops Grown For Seed. If the applicator of this pesticide is not the producer, the applicator must provide a copy of the labeling to the producer of the crop. Producers of this crop who use this product, or cause the product to be used on a field they operate, must provide a copy of this pesticide label to the seed conditioner.
Any seed from a field treated with this pesticide product shall bear specific and conspicuous container labeling, or if shipped in bulk, on the shipment invoice or bill of lading. The labeling shall contain the following statement:
\"This seed was produced using one or more products for which the United States Environmental Protection Agency has not established pesticide residue tolerances. This seed, in whole, as sprouts, or in any form, may not be used for human consumption or animal feed. Failure to comply with this condition may violate requirements of the Federal Food and Drug Administration, the Oregon Department of Agriculture and other regulatory agencies.\"
All seed screenings must be disposed of in such a manner that the screenings cannot be distributed or used for food or feed purposes, as indicated in OAR 603-057-0535. Additional regulations concerning seed screenings are stated in OAR 603-057-0535.
Because there are pesticide residue tolerances for Flumioxazin (active ingredient in Chateau Herbicide WDG ) on alfalfa forage and alfalfa hay, there are no feeding restrictions other than the ones stated above.
