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 SW in soil for residual weed control. Dry weather following applications of Chateau SW may reduce effectiveness. However, when adequate moisture is received after dry conditions, Chateau SW will control susceptible germinating weeds. Chateau SW 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 SW 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 SW should be applied as part of a burndown program to actively growing weeds. Applying Chateau SW under conditions that do not promote active weed growth will reduce herbicide effectiveness. Do not apply Chateau SW 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 SWis 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 SW should only be applied to healthy crops labeled for postemergence use. Do not apply Chateau SW to crops that have been weakened by disease, drought, flooding, excessive fertilization, soil salts, previously applied pesticides, nematodes, insects or winter injury.
Application of Chateau SW 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 SW 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.
Application equipment should be clean and in good repair. Nozzles should be uniformly spaced on boom and frequently checked for accuracy.
Apply Chateau SW, and Chateau SW 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 SW per acre. The rate of Chateau SW required per acre, when applied as a banded application, can be calculated with the formula on the label.
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. To obtain satisfactory application and avoid drift, the following directions must be observed:
- Do not apply during low-level inversion conditions, when winds are gusty or under other conditions that favor drift. Do not spray when wind velocity is less than 2 mph or more than 10 mph.
- Do not apply this product by air within 40 ft. of non-target plants including non-target crops.
- Do not apply this product by air within 100 ft. of emerged cotton crops.
- Do not apply this product by air within 40 ft. of streams, wetlands, marshes, ponds, lakes and reservoirs.
- Carrier Volume and Spray Pressure: When used as part of a burndown weed control program, apply Chateau SW in 7 to 10 gals. of water per acre. Application at less than 7 gals. per acre may provide inadequate control. When used for preemergence weed control, apply Chateau SW in 5 to 10 gals. of water per acre. The higher gallonage applications generally afford more consistent weed control. Do not exceed the nozzle manufacturer’s recommended pressures. For many nozzle types, lower pressure produces larger droplets. When higher flow rates are needed, use higher flow rate nozzles instead of increasing pressure.
- Nozzle Selection and Orientation: Formation of very small drops may be minimized by appropriate nozzle selection, by orienting nozzles away from the air stream as much as possible and by avoiding excessive spray pressure. Use nozzles that produce flat or hollow cone spray patterns. Use non-drip type nozzles, such as diaphragm-type nozzles, to avoid unwanted discharge of spray solution. The nozzles must be directed toward the rear of the aircraft, at an angle between 0 and 15° downward. Do not place nozzles on the outer 25% of the wings or rotors.
- Adjuvants and Drift Control Additives: Refer to tank mix partner’s label for adjuvant recommendation. Drift control additives may be used. When a drift control additive is used, read and carefully observe the cautionary statements and all other information appearing on the additive label.

DIRECTIONS FOR USE TO MAINTAIN BARE GROUND ON NON-CROP AREAS OF FARMS, ORCHARDS AND VINEYARDS
Chateau SW, when used as directed, can be used on farms, orchards and vineyards for non-selective vegetation control to maintain bare ground on non-crop areas that must be kept weed free. Follow all applicable directions as outlined above under “GENERAL INFORMATION”.
Chateau SW offers residual and postemergence control of susceptible broadleaf and grass weeds as well as an additional mode of action to assist in the control of ALS (acetolactate synthase) resistant weeds. Chateau SW can be tank mixed with the herbicides listed in Table 8 for increased residual or postemergence control. The length of residual control is dependent on the rate applied as well as on rainfall and temperature conditions. Length of residual control will decrease as temperature and precipitation increase. Chateau SW rate of 12 oz./A is required to provide residual control of the weeds listed in Table 7.
Apply 12 oz. (0.38 lb. ai/A) of Chateau SW per broadcast acre as a preemergence application. Preemergence (to weed emergence) applications of Chateau SW should be made to a weed-free soil surface. Preemergence applications of Chateau SW must be completed prior to weed emergence. Moisture is necessary to activate Chateau SWon soil for residual weed control. Dry weather following application of Chateau SWmay reduce effectiveness. However, when adequate moisture is received after dry conditions, Chateau SW will control susceptible germinating weeds.
Apply 6 to 12 oz. (0.188 to 0.38 lb. ai/A) of Chateau SW per broadcast acre plus an adjuvant (0.25% v/v non-ionic surfactant or 1 qt./A crop oil concentrate). The addition of an adjuvant enhances Chateau SW activity on emerged weeds. Thorough spray coverage is necessary to maximize the postemergence activity of Chateau SW. Emerged weeds are controlled postemergence with Chateau SW, however, translocation of Chateau SW within a weed is limited, and control is affected by spray coverage and by the addition of an adjuvant. The most effective postemergence weed control with Chateau SW occurs when applied in combination with a surfactant to weeds less than 2 inches in height. A tank mix partner should be used in combination with Chateau SW for the postemergence control of weeds larger than 2 inches. Recommended tank mix partners are listed in Table 8.
IMPORTANT: Completely read and follow the label of any potential tank mix partner with Chateau SW. When using tank mixtures, use conditions must be in accordance with the most restrictive of the label limitations and precautions on either herbicide label.
Chateau SW can be used on soils with greater than 10% organic matter; however, length of residual control may be shorter than on soils with lower organic matter content.
A maximum Chateau SWrate of 6 oz./A per application should be used on any soil that has a sand content over 80% if trees or vines are under 3 years of age.
