FORESTRY RELEASE - EASTERN US - RED PINE - LOAMY SAND AND SANDY LOAM

General Information

PRODUCT INFORMATION

Velpar L VU Herbicide is a water-dispersible liquid that is mixed in water and applied as a spray for weed control in Christmas trees, forestry site preparation and release areas, and industrial areas. It may also be applied undiluted as a basal soil treatment for brush control in reforestation areas, rangeland, pastures and non-crop areas, or by stem injection for brush control.

Velpar L VU Herbicide is an effective general herbicide providing both contact and residual control of many annual, biennial and perennial weeds and woody plants. Velpar L VU Herbicide is noncorrosive to equipment.

Care must be exercised when applying Velpar L VU Herbicide near desirable trees or shrubs as they can absorb Velpar L VU Herbicide through roots extending into treated areas.

This product may be applied on agricultural and nonagricultural 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 permissible to treat intermittent drainage, 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. 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

Velpar L VU Herbicide is absorbed through the roots and foliage. Moisture is required to activate Velpar L VU Herbicide in the soil. Best results are obtained when the soil is moist at the time of application and 1/4–1/2 inches of rainfall occurs within 2 weeks after application. For best results, apply Velpar L VU Herbicide preemergence or postemergence when weeds are less than 2 inches in height or diameter. Foliar activity is most effective under conditions of high temperature (above 80 °F), high humidity, and good soil moisture. Foliar activity may be reduced when vegetation is dormant, semi-dormant, or under stress.

On herbaceous plants, symptoms usually appear within 2 weeks after application under warm, humid conditions, while 4–6 weeks may be required when weather is cool or dry, or when plants are under stress. If rainfall after application is inadequate to activate Velpar L VU Herbicide in the soil, plants may recover from contact effects and continue to grow. On woody plants, symptoms usually appear within 3–6 weeks after sufficient rainfall has carried the herbicide into the root zone during periods of active growth. Defoliation and refoliation may occur, but susceptible plants are killed.

The degree and duration of control may depend on the following:
- Use rate
- Weed spectrum and size at application
- Environmental conditions at and following treatment

Where a rate range is shown, use the higher levels of the dosage range on hard-to-control species, fine-textured soils, or soils containing greater than 5% organic matter or carbon. Use the lower levels of the dosage range on coarse-textured soils and/or on soils low in organic matter. Refer to specific uses for rate ranges.

APPLICATION INFORMATION

Velpar L VU Herbicide may be applied by ground equipment and, where permitted, aerial equipment. Use rates, minimum spray gallonage, and other application information are described for the various uses. Dispose of the equipment washwater by applying it to a use-site listed on this label or in accordance with directions given in the “Storage and Disposal” section of this label. Before spraying, calibrate equipment to determine the quantity of water necessary to uniformly and thoroughly cover the vegetation and soil in a measured area to be treated.

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 advised, 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 instructions 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.

Limitations, Restrictions, and Exceptions

FORESTRY RELEASE

APPLICATION INFORMATION
EASTERN US
Apply Velpar L VU Herbicide from early spring to early summer after hardwoods have broken bud and before full leaf expansion.
Applications made over the top of pines may result in excessive pine injury under conditions of high humidity and temperature (80 degrees F).

USE RATES
The rates listed below are for broadcast application. Use the higher rate range for the harder to control (*suppression) species in the PLANTS CONTROLLED listings of the Site Prep
and Release sections. Do not use more than one application of Velpar L VU Herbicide per year.

ESTABLISHED TREES
- 4 years of age from transplanting on coarse-textured soils
- 3 years of age from transplanting on medium-textured soils
- 2 years of age from transplanting for Red Pine

BRUSH CONTROLLED
Dogwood, flowering, Honeysuckle, Maple, red, Sourwood: Suppression – a visible reduction in plant population and/or plant vigor as compared to an untreated area and generally not accepted as control.
In addition to brush controlled, herbaceous species listed in Weeds Controlled section of Release-Herbaceous Weed Control may be controlled with these applications.

SPRAY EQUIPMENT
When applied as a liquid spray using water as the carrier, Velpar L VU Herbicide may be applied by ground equipment or by air (helicopter only).
For ground application, use enough water for thorough coverage, usually a minimum of 25 gallons per acre. For aerial applications, use at least 5 gallons of water per acre and at least 5 gallons of water for every 1 gallon of Velpar L VU Herbicide.

USE PRECAUTIONS AND RESTRICTIONS RELEASE - UNDILUTED APPLICATIONS

- Application of Velpar L VU Herbicide basal soil spot treatments closer than 36 inches to conifer seedlings in their first season or directly up slope from these seedlings may result in injury or mortality.

- Use Velpar L VU Herbicide on seedlings in their first or fourth year and older. Injury may result from use on two and three year old seedlings where root growth is extensive but hardiness is lacking.

FORESTRY—IMPREGNATION ON DRY BULK FERTILIZER
Velpar L VU Herbicide is labeled for impregnating or coating dry bulk fertilizer to be applied on forested sites for the establishment or release of conifer plantations (except longleaf pine) as specified on this label.

PLANTS CONTROLLED
Fertilizer impregnated with Velpar L VU Herbicide is labeled for the control and suppression of the weeds and brush identified for the specific applications on this label. Consult the appropriate segment of this label to determine the appropriate rate of Velpar L VU Herbicide to be applied per acre. Apply this amount of Velpar L VU Herbicide to the volume of fertilizer to be applied per acre.

IMPREGNATION EQUIPMENT
To impregnate or coat the fertilizer use a system consisting of conveyor or closed drum used to blend dry bulk fertilizer.

IMPREGNATION INSTRUCTIONS
Velpar L VU Herbicide may be used undiluted or mixed with a sufficient quantity of water to ensure thorough coverage of the fertilizer.
Direct the spray nozzles of the impregnation equipment to deliver a fine spray of the mixture toward the fertilizer for thorough coverage while avoiding contact with mixing equipment.
The use of a colorant or dye may be beneficial to visually determine the uniformity of impregnation.
Uniform impregnation of dry bulk fertilizer may vary. If absorption of the spray is not adequate, the use of an absorptive powder or additive, such as “Microcel E” or “HiSil 233”, may be required to produce a dry, free flowing mixture.
Apply the fertilizer as soon as possible after impregnation for optimum performance. Impregnated fertilizer may become lumpy and difficult to apply following storage.
Diammonium phosphate, potassium chloride, 16-16-16 and 24-4-4 have been successfully impregnated.

APPLICATION EQUIPMENT
Applications of impregnated fertilizer may be made by ground equipment or by air (helicopter or fixed wing). Accurate calibration and patterning of the equipment is essential for uniform distribution of the impregnated fertilizer on the soil surface.

USE PRECAUTIONS AND RESTRICTIONS FORESTRY - IMPREGNATED FERTILIZER
- If fertilizer materials are excessively dusty, use a suitable additive to reduce dust prior to impregnation. Application of dusty fertilizer which has been impregnated may result in off-target drift and injury to desirable vegetation. Such drift and associated injury may be aggravated by high wind conditions.
- The dry fertilizer must be properly impregnated and uniformly applied to avoid pine injury/mortality and poor weed and brush control.
- Uniform and precise application of the impregnated fertilizer is essential for satisfactory weed and brush control and to minimize pine injury. Overlaps or skips between adjoining swaths or nonuniform distribution of impregnated fertilizer within the swath will deliver poor results and may result in pine injury or mortality.
- Do not impregnate potassium nitrate, sodium nitrate or triple super phosphate fertilizers with Velpar L VU Herbicide as herbicidal action will be lost.

USE PRECAUTIONS AND RESTRICTIONS FORESTRY
- Do not use Velpar L VU Herbicide in nurseries, seedbeds, or ornamental plantings.
- On tracts of land where various soil types are present and Velpar L VU Herbicide rate selection is difficult, conifer damage or less-than-expected vegetation suppression may occur due to the different rates required for various soil types.
- Poor weed and brush control may result from the following:
– Heavy duff or slash present at time of application.
– Use on poorly drained sites.
– Applications made when the soil is saturated with water and rain is imminent within 24 hours.
– Applications to soils high in organic matter (greater than 5%).
- Following harvest, allow stumps and injured trees sufficient time to adequately resprout before applying Velpar L VU Herbicide.
- Where burning is desired, burn vegetation only after any brush has completely defoliated, at least twice, allowing for sufficient root uptake of Velpar L VU Herbicide.
- Do not use Velpar L VU Herbicide on frozen soils; use in spring after snow melt.
- Leave treated soil undisturbed to reduce the potential for Velpar L VU Herbicide, movement by soil erosion due to wind or water.
- Do not add a surfactant in applications over the top of conifers.
- Weed control results from spring applications depend on sufficient moisture to activate Velpar L VU Herbicide.
- When applying Velpar L VU Herbicide after transplanting, wait until rainfall has settled the soil around the base and root systems of the transplants before making the treatment.
- Crop injury may occur when Velpar L VU Herbicide is used:
– On trees that show poor vigor, insect damage, disease, winter injury, or other stress conditions
– On any soil containing less than 1% organic matter
– On loamy sand or sandy loam with less than 2% organic matter, except Jeffrey pine and Ponderosa pine
– On conifer foliage after conifer bud break
– On gravelly or rocky soils, exposed subsoils, clay knobs, sand, or sandy soil with 85% or more sand
– On crop species not listed on this label
- Livestock may be grazed immediately following a broadcast application of Velpar L VU Herbicide at rates of 4.5 pints per acre or less, and treated vegetation may be cut, dried, and fed after 38 days.
- Do not cut treated vegetation for feed, or graze livestock on treated areas for 60 days following application of Velpar L VU Herbicide at broadcast rates exceeding 4.5 pints per acre.
