• 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.
NON-AGRICULTURAL USES
APPLICATION INFORMATION
VELPAR® DF is recommended for general weed and brush
control in noncrop sites such as railroads, highways, utility and
pipeline rights-of-way, petroleum tank farms, storage areas,
industrial plant sites, and other similar areas.
VELPAR® DF is recommended for control of many annual,
biennial, and perennial weeds in noncrop, industrial sites.
APPLICATION TIMING
Apply VELPAR® DF as a preemergence or postemergence
spray when weeds are actively germinating or growing.
WEEDS CONTROLLED - USE RATE
VELPAR® DF effectively controls the following weeds when
applied at the use rates shown. When applied at lower rates,
VELPAR® DF provides short-term control of the weeds listed;
when applied at higher rates, weed control is increased and
extended.
Use 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.
