PRODUCT INFORMATION

WESTAR herbicide is a dispersible granule that is mixed in water and applied as a spray. WESTAR may be used for weed control in terrestrial non-crop sites and for the control of certain weeds in conifers grown for forestry and Christmas tree production.

WESTAR is an effective herbicide providing both contact and residual control of many annual and perennial weeds. WESTAR can be tank mixed with other herbicides registered for use in forestry, Christmas tree and non-crop sites. Read and follow the Directions for Use for both products. WESTAR is non-corrosive to spray or mixing equipment, non-flammable and non-volatile.

Precaution must be exercised when applying WESTAR near desirable trees or shrubs as they can absorb WESTAR through roots extending into treated areas.

This product may be applied on forestry, Christmas tree and non-crop sites that contain areas of temporary surface water caused by collection of water between planting beds, in equipment ruts, or in other depressions created by management activities. It is permissable to treat intermittently flooded low lying areas, seasonally dry flood plains and transitional areas between upland and lowland sites when no water is present. It is also permissible to treat marshes, swamps and bogs after water has receded, as in seasonally dry flood deltas.

A drift control agent may be used at the manufacturer's listed rate in the application of WESTAR.

INVASIVE SPECIES MANAGEMENT

This product may be considered for use on public, private, and tribal lands to treat certain weed species infestations that have been determined to be invasive, consistent with the Federal Interagency Committee for the Management of Noxious and Exotic Weeds (FICMNEW) National Early Detection and Rapid Response (EDRR) System for invasive plants. Effective EDRR systems address invasions by eradicating the invader where possible, and controlling them when the invasive species is too established to be feasibly eradicated. Once an EDRR assessment has been completed and action is recommended, a Rapid Response needs to be taken to quickly contain, deny reproduction, and if possible eliminate the invader. Consult your appropriate state extension service, forest service, or regional multidisciplinary invasive species management coordination team to determine the appropriate Rapid Response provisions and allowed treatments in your area.

RESISTANCE

When herbicides that affect the same biological site of action are used repeatedly over several years to control the same weed species in the same field, naturally-occurring resistant biotypes may survive a correctly applied herbicide treatment, propagate, and become dominant in that field. Adequate control of these resistant weed biotypes cannot be expected. If weed control is unsatisfactory, it may be necessary to retreat the problem area using a product affecting a different site of action. To better manage herbicide resistance through delaying the proliferation and possible dominance of herbicide resistant weed biotypes, it may be necessary to change cultural practices within and between crop seasons such as using a combination of tillage, retreatment, tank-mix partners and/or sequential herbicide applications that have a different site of action. Weed escapes that are allowed to go to seed will promote the spread of resistant biotypes.

It is advisable to keep accurate records of pesticides applied to individual fields to help obtain information on the spread and dispersal of resistant biotypes. Consult your agricultural dealer, consultant, applicator, and/or appropriate state agricultural extension service representative for specific alternative cultural practices or herbicide recommendations available in your area.

INTEGRATED PEST MANAGEMENT

This product may be used as part of an Integrated Pest Management (IPM) program that can include biological, cultural, and genetic practices aimed at preventing economic pest damage. IPM principles and practices include field scouting or other detection methods, correct target pest identification, population monitoring, and treating when target pest populations reach locally determined action thresholds. Consult your state cooperative extension service, professional consultants or other qualified authorities to determine appropriate action treatment threshold levels for treating specific pest/crop systems in your area.

PREPARING FOR USE

- Site Specific Considerations

Understanding the risks associated with the application of DuPont WESTAR is essential to aid in preventing offsite injury to desirable vegetation and agricultural crops. The risk of off-site movement both during and after application may be affected by a number of site specific factors such as the nature, texture and stability of the soil, the intensity and direction of prevailing winds, vegetative cover, site slope, rainfall, drainage patterns, and other local physical and environmental conditions. A careful evaluation of the potential for off-site movement from the intended application site, including movement of treated soil by wind or water erosion, must be made prior to using WESTAR. This evaluation is particularly critical where desirable vegetation or crops are grown on neighboring land for which the use of WESTAR is not labeled. If prevailing local conditions may be expected to result in off-site movement and cause damage to neighboring desirable vegetation or agricultural crops, do not apply WESTAR.

Before applying WESTAR the user must read and understand all label directions, precautions and restrictions completely, including these requirements for a site specific evaluation. If you do not understand any of the instructions or precautions on the label, or are unable to make a site specific evaluation yourself, consult your local agricultural dealer, cooperative extension service, land managers, professional consultants, or other qualified authorities familiar with the area to be treated. If you still have questions regarding the need for site specific considerations, please call 1-888-6-DUPONT.

Limitations, Restrictions, and Exceptions

NON-AGRICULTURAL SITES

APPLICATION INFORMATION

DuPont WESTAR is labeled for general weed control on private, public and military lands as follows: Uncultivated non-agricultural areas (including airports, highway, railroad and utility rights-of-way (ROW), sewage disposal areas); uncultivated agricultural areas--noncrop producing (including farmyards, fuel storage areas, fence rows, barrier strips); industrial sites--outdoor (including lumberyards, pipeline and tank farms).

WESTAR is not labeled for use on recreation areas or for direct application to paved areas (surfaces). Apply by ground equipment or helicopter only.

GROUND

Be sure the sprayer is calibrated prior to use. Select a spray volume and delivery system that will ensure thorough weed coverage and a uniform spray pattern. To help maintain the correct application rate within the treated site, avoid over-spraying treated areas and turn off spray boom (or spray boom section) when turning, slowing or stopping.

AIR (HELICOPTER ONLY)

Be sure the sprayer is calibrated prior to use. Select a spray volume and delivery system that will ensure thorough weed coverage and a uniform spray pattern. Avoid overlapping the spray pattern and shut off spray boom when starting, turning or slowing to avoid injury to desired species. APPLICATION TIMING

Apply WESTAR preemergence or early postemergence (shortly after emergence) to herbaceous weeds (broadleaves and grasses).

WEEDS CONTROLLED - USE RATE

WESTAR controls the following weeds when applied at the indicated rates. When applied at the lower rate, WESTAR provides short-term control of the weeds listed below; when applied at the higher rates, weed control is extended. Use the lower rate on coarse textured soils and the higher rate on soils high in organic matter or on fine textured soils. For best control, use the higher rate on weeds identified (*) as hard to control in the weed list.

- Cinquefoil, Common sorrel, Crowfootgrass, Red sorrel: Indicates difficult to control. Use higher end of the rate range specified.

USE PRECAUTIONS AND RESTRICTIONS NON-CROP

- Do not tank mix WESTAR with DuPont HYVAR XL.

ADDITIONAL INSTRUCTIONS PRECAUTIONS AND RESTRICTIONS FOR AGRICULTURAL AND NON-AGRICULTURAL USES

- Do not apply this product through any type of irrigation system.

- Do not use in nurseries, seed beds or ornamental plantings.

- Poor weed control may occur when applications are made to saturated soil and rain occurs within 24 hours.

- Do not drain or flush equipment on or near desirable trees or other plants, or on areas where their roots may extend, or in locations where the chemical may be washed or moved into contact with their roots as injury or loss of desirable trees and other plants may result.

- Applications made where runoff water flows onto agricultural land may injure crops. Applications made during periods of intense rainfall, to soils saturated with water, surfaces paved with material such as asphalt or concrete, or soils through which rainfall will not readily penetrate may result in runoff and movement.

- Leave treated soil undisturbed to reduce the potential for DuPont WESTAR movement by soil erosion due to wind or water.

- Do not apply when the soil is frozen or covered with snow or standing water.

- Treatment of powdery, dry soil or light, sandy soil when there is little likelihood of rainfall soon after treatment may result in off target movement and possible damage to susceptible crops when soil particles are moved by wind or water. Injury to crops may result if treated soil is washed, blown, or moved onto land used to produce crops. Exposure to WESTAR may injure or kill most crops. Injury may be more severe when the crops are irrigated. Do not apply WESTAR when these conditions are identified and powdery, dry soil or light or sandy soil are known to be prevalent in the area to be treated.

- Applications may not be made to soil that is subject to wind erosion when less than a 60% chance of rainfall is predicted to occur in the treatment area within 48 hours. Soils that are subject to wind erosion usually have a high silt and/or fine to very fine sand fractions. Soils with low organic matter also tend to be prone to wind erosion.

- Do not use WESTAR on lawns, driveways, tennis courts, or residential or recreational areas.

- If the treated site is to be converted to an agricultural (food, feed or fiber) or horticultural crop, do not plant the treated site(s) for at least one year after the WESTAR application. A field bioassay must then be completed before planting to crop. To conduct a field bioassay, grow to maturity test strips of the crop you plan to grow the following year. The test strips should cross the entire field including knolls and low areas. Crop response to the bioassay will indicate whether or not to plant the crop grown in the test strips. In the case of suspected off-site movement of WESTAR to crop-land, in addition to conducting the above described bioassay, soil samples should be taken and quantitatively analyzed by an analytical laboratory for WESTAR or any other herbicide which could have an adverse effect on the crop.

- Do not use this product in the following counties of Colorado: Saguache, Rio Grande, Alamosa, Costilla and Conejos.

- Do not apply in or on irrigation ditches or canals including their outer banks.

- If tank mixing this product with other pesticides, follow the directions for determining compatibility with tank mix partners prior to tank mixing them. Follow instructions for determining compatibility given under MIXING WITH OTHER HERBICIDES in the SPRAY PREPARATION section of the label.
