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 non-uniform 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 DuPont™ VELPAR® DF as herbicidal action will be lost.

USE PRECAUTIONS

FORESTRY

•Do not use VELPAR® DF in nurseries, seedbeds, or ornamental plantings.

•On tracts of land where various soil types are present and VELPAR® DF 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® DF.

•Where burning is desired, burn vegetation after any brush has completely defoliated, at least twice, allowing for sufficient root uptake of VELPAR® DF.

•Do not use VELPAR® DF on frozen soils; use in spring after snow melt.

•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® DF.

•When applying VELPAR® DF 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® DF 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.

•Do not cut treated vegetation for forage or hay nor graze domestic animals on treated areas for 60 days following application.

YELLOW POPLAR PLANTINGS

VELPAR® DF is recommended for the control of herbaceous weeds in the establishment of yellow poplar plantations. Applications may be made over the top of planted seedlings after the soil has settled around the root systems but before the seedlings have broken dormancy (bud break). A subsequent application may be made before dormancy break in the Spring of the second year. USE RATES: Use the rate range specified in the "RELEASE- HERBACEOUS WEED CONTROL" section for pine plantations - eastern US.

For ground application, use sufficient spray volume for uniform and thorough coverage of the site to be sprayed, usually a minimum of 25 gallons per acre. For aerial applications, use a minimum of 5 gallons of water per acre. For broader spectrum control VELPAR® DF may be tank mixed with DuPont™ ESCORT® XP herbicide. Add ESCORT® XP at a rate of 1/2 ounce per acre with the prescribed rate of VELPAR® DF.

USE PRECAUTIONS

YELLOW POPLAR PLANTINGS

•Applications of VELPAR® DF and tank mixes of VELPAR® DF and DuPont™ ESCORT® XP made to yellow poplar seedlings that are suffering from loss of vigor caused by insects, disease, drought, winter damage, animal damage, excessive soil moisture, planting shock or other stresses may injure or kill the seedlings.

•Applications of VELPAR® DF and tank mixes of VELPAR® DF and ESCORT® XP should only be made after adequate rainfall has closed the planting slit and settled the soil around the roots following transplanting.

•The use of surfactant with VELPAR® DF is not recommended for applications made over the tops of seedlings.

•Careful consideration must be given by an experienced and knowledgeable forester to ensure the specific growth requirements of yellow poplar will be provided by the selected planting site. Treatment of yellow poplar planted on a site inadequate to meet its requirements may injure or kill the seedlings.

PASTURE / RANGELAND

VELPAR® DF is recommended for control of brush and weeds in pasture.

BERMUDAGRASS / BAHIAGRASS

VELPAR® DF is recommended for control of smutgrass and other weeds in established stands of bermudagrass and bahiagrass.
