DuPont Authentication Velpar H - 65396 - Manual (Page 20)

USE PRECAUTIONS
FORESTRY
• Do not use DuPont™ VELPAR® L in nurseries, seedbeds, or
ornamental plantings.
• On tracts of land where various soil types are present and
VELPAR® L 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.
• Where burning is desired, burn vegetation only after any
brush has completely defoliated, at least twice, allowing for
sufficient root uptake of VELPAR® L
• Do not use VELPAR® L 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® L.
• When applying VELPAR® L 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 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
• 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® L 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.
Apply 4 to 6 pints per acre of VELPAR® L as
recommended on the package label for "RELEASE—
HERBACEOUS WEED CONTROL" in pine plantations in
the eastern U.S. Follow the label recommendations
regarding varying the application rate by soil texture.
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.
For broader spectrum control VELPAR® L may be tank
mixed with DuPont™ ESCORT® herbicide. Add
ESCORT® at a rate of 1/2 ounce per acre to a tank mix with
the prescribed rate of VELPAR® L.
USE PRECAUTIONS
YELLOW POPLAR PLANTINGS
• Applications of VELPAR® L and tank mixes of
VELPAR® L and ESCORT® 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® L and tank mixes of
VELPAR® L and ESCORT® 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® L 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.
• Refer to package labels for information regarding spray
drift management.
VELPAR® L is recommended for control of brush and weeds in
pasture.
BERMUDAGRASS / BAHIAGRASS
VELPAR® L is recommended for control of smutgrass and
other weeds in established stands of bermudagrass and
bahiagrass.
APPLICATION INFORMATION
Make a single application of VELPAR® L per year when weeds
are actively growing.
WEEDS CONTROLLED - USE RATES
VELPAR® L effectively controls the following weeds at the
rates shown. Use a lower rate on coarse-textured soils (sand to
sandy loam). Use the higher rate on fine-textured soils (clay
loam to clay) and on soils high in organic matter.
