ROADSIDE TURFGRASS - COGONGRASS
PERSPECTIVE herbicide is a dispersible granule that is mixed in water and applied as a spray. PERSPECTIVE herbicide may be applied by ground equipment only, except for rights-of-ways which may also be applied by helicopter.
- for control of broadleaf weeds, including many terrestrial and riparian invasive and noxious weeds. PERSPECTIVE is registered for general weed control on private, public and military lands as follows: uncultivated non-agricultural areas (such as airports, highway, railroad and utility rights-of-way, sewage disposal areas, etc.); uncultivated agricultural areas - non-crop producing (such as farmyards, fuel storage areas, fence rows, non-irrigation ditchbanks, barrier strips, etc.); industrial sites - outdoor (such as lumberyards, pipeline and tank farms, etc.) and natural areas (such as wildlife management areas, wildlife openings, wildlife habitats, recreation areas, campgrounds, trailheads, and trails).
PERSPECTIVE may be used for the release or restoration of native perennial grasses and in established, industrial turf grasses.
This product may be applied to terrestrial non-crop sites and unimproved turf 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 sites, 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 well as seasonally dry flood deltas. PERSPECTIVE may be applied up to the waters edge. Do not apply directly to water.
PERSPECTIVE provides preemergence and/or postemergence control of the broadleaf weeds species listed in the weeds controlled section of the label. For perennial species on the label, a postemergence application must be used. For best postemergence performance, add a high quality adjuvant to the spray solution. Excessive wetting of the target plant is not necessary but good spray coverage of the target plant is needed for best results.
PERSPECTIVE is non-corrosive to spray equipment.
Do not apply more than 11 ounces of product per acre per year. Do not apply more than three times per year.
PERSPECTIVE is quickly taken up by the leaves, stems and roots of plants. The effects of PERSPECTIVE may be seen on plants from within a few hours to a few days. The most noticeable symptom is a bending and twisting of stems and leaves. Other advanced symptoms include severe necrosis, stem thickening, growth stunting, leaf crinkling, calloused stems and leaf veins, leaf-cupping, and enlarged roots. Death of treated broadleaf plants may require several more weeks and up to several months for some woody plant species.
PERSPECTIVE is rain-fast at 4 hours after application.
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.
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 site, 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 practices such as using a combination of 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 sites to help obtain information on the spread and dispersal of resistant biotypes. Consult your agricultural reseller, 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 PERSPECTIVE 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 PERSPECTIVE. This evaluation is particularly critical where desirable vegetation or crops are grown on neighboring land for which the use of PERSPECTIVE 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 PERSPECTIVE.
Before applying PERSPECTIVE 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 with your local DuPont Crop Protection representative, local agricultural dealer, university cooperative extension service, land manager, professional applicator, agricultural consultant, 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.
Apply DuPont PERSPECTIVE preemergence or early postemergence when broadleaf weeds are actively germinating or growing. PERSPECTIVE can provide long term control of susceptible weeds. The length of control is dependent upon the application rate, condition and growth stage of target weeds, environmental conditions at and following application, and the density and vigor of competing desirable vegetation. Best results for long term weed control occur where grasses and other vegetation is allowed to recover from adverse environmental conditions and compete with susceptible weeds. Do not apply more than three times per year.
PERSPECTIVE may also be applied using low and high volume ground spray equipment. PERSPECTIVE may be applied by helicopter on rights-of-ways only.
LOW VOLUME APPLICATION
See Table 1. PERSPECTIVE Spray Volume and Use Rate Mixing Instructions chart. Adjust PERSPECTIVE spray concentration according to the spray volume per acre and the size and plant density of the target weed species. Use spray nozzles and pressure that will aid the proper deposition of the spray solution. Apply in sufficient spray volume to insure uniform spray distribution of spray particles over the area to be treated and to avoid spray drift.
HIGH VOLUME APPLICATION
High volume applications may be applied at rates equivalent to broadcast rates up to 11 ounces product per acre per year.
Apply PERSPECTIVE in sufficient water to ensure thorough and uniform wetting of the target site. For best results, add an adjuvant to the spray solution. See Table 1.
PERSPECTIVE Spray Volume and Use Rate Mixing Instructions chart.
Use a sufficient volume of water to ensure thorough coverage when applying PERSPECTIVE 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. Avoid overlapping and shut off spray booms while starting, turning, slowing, or stopping to avoid injury to desired species.
Air (Helicopter on Rights-of-Ways Only)
PERSPECTIVE may be applied aerially by helicopter spray equipment only on rights-of-ways. However, do not make application by air unless appropriate buffer zones can be maintained to minimize potential spray drift out of the target areas.
Select a spray volume and delivery system that will ensure thorough coverage and a uniform spray pattern. Be sure the sprayer is calibrated. Avoid overlapping and shut off spray booms while starting, turning or slowing to avoid injury to desired species.
The application volume required will vary with the height and density of the brush and the type of application equipment.
In general, aerial application spray volumes range from 15 to 25 gallons per acre.
INDUSTRIAL TURFGRASS (UNIMPROVED ONLY)
Apply DuPont PERSPECTIVE for selective weed control in unimproved, well established industrial turfgrasses on roadsides, utility rights-of-way, airports and other non-crop sites. Use a surfactant at the rate of 1 to 2 pints per 100 gallons of spray solution. Treatments made prior to the full green-up stage may delay green-up. A temporary yellowing and/or stunting of the turfgrass may be observed following an application of PERSPECTIVE.
Apply PERSPECTIVE by ground equipment only. Use a minimum of 10 gallons of water per acre. The addition of an MSO adjuvant may increase the potential for turfgrass injury. In addition to conventional spray equipment, PERSPECTIVE may also be applied with invert emulsion equipment. When using an invert emulsion, mix the prescribed rate of PERSPECTIVE in the water phase.
For turfgrass species that are not listed on the label, determine the suitability for such uses by treating a small area at a labeled application rate. Prior to treatment of larger areas, the treated area must be observed for any signs of herbicidal injury during 30 days of normal growing conditions to determine if the treatment is safe to the target species. The user assumes the responsibility for any plant damage or other liability resulting from use of PERSPECTIVE on a turfgrass species not listed on the label.
Excessive injury may result when PERSPECTIVE is applied to turfgrass that is under stress from drought, insects, disease, temperatures (winter injury) or poor fertility.
SPECIFIC WEED PROBLEMS: COGONGRASS
In roadside turfgrass sites, apply PERSPECTIVE at a minimum of 5 ounces per acre for seedhead suppression of cogongrass. For cogongrass control (stand reduction), apply PERSPECTIVE at 10 to 11 ounces per acre. Multiple applications will be required for best control. Best results when applied after final seasonal mowing of roadsides.
