NON-AGRICULTURAL USES - NON-CROP SITES

General Information

PRODUCT INFORMATION

DuPont THROTTLE XP is formulated as a water dispersible granule. THROTTLE XP is to be mixed in water and applied as a spray on non-agricultural sites. THROTTLE XP controls many annual and perennial grasses and broadleaf weeds in non-agricultural sites.

THROTTLE XP can be tank mixed with other herbicides registered for use in non-agricultural sites; when tank mixing, use the most restrictive limitations from the labeling of the products being used.

THROTTLE XP controls weeds by both preemergence and postemergence activity. The best results are obtained when the application is made at or before the early stages of weed growth; before weeds develop an established root system.

Moisture is required to move THROTTLE XP into the root zone of weeds for preemergence control. Best results are obtained if moisture for activation is supplied by rainfall within two weeks after application.

For best postemergence results, apply THROTTLE XP to young, actively growing weeds. The degree and duration of control may depend on the following:

- weed spectrum and infestation intensity

- weed size at application

- environmental conditions at and following treatment

- soil pH, soil moisture, and soil organic matter

Do not use on food or feed crops.

Contact with desirable vegetation either directly or through drift may cause severe plant injury or death.

This product may be applied on non-agricultural sites that contain areas of temporary surface water caused by collection of water in equipment ruts or in other depressions created by management activities. It is permissible 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. Do not make applications to natural or man-made bodies of water such as lakes, reservoirs, ponds, streams and canals.

ENVIRONMENTAL CONDITIONS AND BIOLOGICAL ACTIVITY

When applied as a spray, THROTTLE XP is absorbed by both the roots and foliage of plants, rapidly inhibiting the growth of susceptible weeds.

Warm, moist conditions following application accelerate the herbicidal activity of THROTTLE XP; cold, dry conditions delay the herbicidal activity. In addition, weeds hardened-off by drought stress are less susceptible to THROTTLE XP.

Moisture is needed to move THROTTLE XP into the soil for preemergence weed control.

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.

INVASIVE SPECIES MANAGEMENT

This product may be used 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.

PREPARING FOR USE - Site Specific Considerations

Understanding the risks associated with the application of is essential to aid in preventing off-site 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 DuPont THROTTLE XP. This evaluation is particularly critical where desirable vegetation or crops are grown on neighboring land for which the use of THROTTLE XP 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 THROTTLE XP.

Before applying THROTTLE XP 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.

USE PRECAUTIONS AND RESTRICTIONS

- Injury to or loss may occur if equipment is drained or flushed 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.

- Leave treated soil undisturbed to reduce the potential for THROTTLE XP movement by soil erosion due to wind or 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 THROTTLE XP may injure or kill most crops. Injury may be more severe when the crops are irrigated. Do not apply THROTTLE XP 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.

- 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 materials such as asphalt or concrete, or soils through which rainfall will not readily penetrate may result in runoff and movement of THROTTLE XP.

- Do not treat frozen or snow covered soil.

- Do not use on lawns, walks, driveways, tennis courts, or similar areas.

- Keep from contact with fertilizers, insecticides, fungicides, and seeds.

- Do not apply in or on irrigation ditches or canals including their outer banks or to water used for crop irrigation or for domestic uses.

- Do not apply through any type of irrigation system.

- Low rates of DuPont THROTTLE XP can kill or severely injure most crops. Following an THROTTLE XP application, the use of spray equipment to apply other pesticides to crops on which THROTTLE XP is not registered may result in their damage. The most effective way to reduce this crop damage potential is to use dedicated mixing and application equipment.

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

- If noncrop or forested sites treated with THROTTLE XP are to be converted to a food, feed, or fiber agricultural crop, or to a horticultural crop, do not plant the treated sites for at least one year after the THROTTLE XP application. A field bioassay must then be completed before planting to crops.

Limitations, Restrictions, and Exceptions

NON-AGRICULTURAL SITES

APPLICATION INFORMATION

THROTTLE XP is labeled for general weed control on private, public and military lands as follows: Uncultivated nonagricultural 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).

THROTTLE XP is not labeled for use on recreation areas or for direct application to paved areas (surfaces).

NOTE: Application to non-agricultural sites, except rights-of-way, is restricted to ground application only. Rights-of-way may be treated by ground application or by helicopter.

Do not tank mix THROTTLE XP with DuPont HYVAR X-L herbicide.

APPLICATION TIMING

Apply DuPont THROTTLE XP as a preemergence or early postemergence spray when weeds are actively germinating or growing. When weeds are emerged at application a postemergence burn down herbicide, such as glyphosate, should be included in the treatment.

SPECIFIC WEED PROBLEMS

NON-CROP SITES

Prickly Lettuce

Since biotypes of prickly lettuce are known to be resistant to DuPont THROTTLE XP, tank mixture combinations with herbicides having different modes of action, such as DuPont HYVAR X or DuPont KROVAR I DF, must be used.

In areas where resistance is known to exist, these weeds should be treated postemergence with other herbicides registered for their control, such as 2,4-D, diuron or dicamba.

SPRAY EQUIPMENT

Low rates of THROTTLE XP can kill or severely injure most crops. Following a THROTTLE XP application, the use of the spray equipment to apply other pesticides to crops on which THROTTLE XP or its active ingredients are not registered may result in their damage. The most effective way to reduce this crop damage potential is to use dedicated mixing and application equipment.

APPLICATION

Use a sufficient volume of water to ensure thorough coverage when applying THROTTLE XP as a broadcast or directed spray. Select a spray volume and delivery system that will ensure thorough coverage and a uniform spray pattern. Be sure the sprayer is calibrated before use. 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.
