VELPAR® L. In the West, results may take one to two years
i
n areas of low rainfall.
SPRAY EQUIPMENT
When applied as a liquid spray using water as the carrier,
VELPAR® L 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.
GRID APPLICATION
Apply undiluted VELPAR® L directly to the soil surface in
a grid pattern using an exact delivery handgun applicator.
This equipment delivers a thin stream of a predetermined
volume. VELPAR® L should be applied during the period
from hardwood bud break to early summer.
Selection of the rate per acre and grid pattern will depend on
soil texture and woody plant composition. Use the lower
rates on coarse textured soils and when the major
component of the hardwoods are susceptible species. Use
the high rates on fine-textured soils and where weeds
identified in the label as “partial control or suppression”
predominate.

BASAL (SOIL)
SINGLE STEM TREATMENT
Apply undiluted VELPAR® L to the soil with an exact
delivery handgun applicator. Apply at the rate of 2–4 ml for
each inch of stem diameter at breast height. Direct the
treatment to the soil within 3 feet of the root collar of woody
plants to be controlled. When treating large stems and when
more than one delivery of VELPAR® L is needed per stem,
make application on opposite sides of the stem.
For multi-stemmed and low-growing brush that have stem
diameters that are difficult to determine, apply VELPAR® L
at the rate of 2–4 ml per 3 feet of canopy width. For tall,
slender (columnar) br
ush types,

When treating br

application of VELPAR® L, apply subsequent applications
equally spaced ar
ound the plant. If treating brush on sloped
sites, apply most of the
VELPAR® L on the uphill side of
the stem. If treating resprouts from brush disturbed by
cutting or shredding, the rate of application should be
p
roportional to the original tree size, not just the small
regrowth of sprouts.
INJECTION

w
hen this product is directly injected into agricultural
plants.
Inject 1 ml of undiluted VELPAR® L through the bark of
undesirable trees. Injections should be made at 4 inch
intervals around the circumference of the tree. When using
tubular injection equipment, inject near the ground level.
When using the “Hypo-Hatchet” Tree Injector or a similar
devise, inject at waist height. Treatment should be made in
the summer. Woody species controlled include black cherry,
oaks, and sweetgum.
USE PRECAUTIONS
SITE PREPARATION
Where burning is desired, burn the vegetation only after any
residual brush has completely defoliated, at least twice,
allowing for sufficient root uptake of VELPAR® L.
Following harvest, allow sufficient time for stumps and
injured trees to adequately resprout before applying
VELPAR® L.
