DuPont Authentication Velpar H - 65396 - Manual (Page 18)

and at least 5 gallons of water for every 1 gallon of
DuPont™ 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
when triggered. Apply VELPAR® L during the period from
hardwood bud break to early summer.
Selection of the rate per acre and grid pattern depends 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 this 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) brush types, apply 4–8 ml per 3 feet of height. Base
rate on whichever canopy dimension is greater (width or height).
When treating brush that requires more than a single 4 ml
application of VELPAR® L, apply subsequent applications
equally spaced around 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 proportional to the original tree
size, not just the small regrowth of sprouts.
INJECTION
No Worker Protection Standard worker entry restrictions or
worker notification requirements apply when 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 VELPAR® L 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
RELEASE UNDILUTED APPLICATIONS
• Application of VELPAR® L spots 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 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.
RELEASE- HERBACEOUS WEED CONTROL
VELPAR® L is recommended for controlling herbaceous weeds
where the following species are grown for forestry release sites:
EASTERN US
WESTERN US
APPLICATION TIMING
EASTERN US
Apply VELPAR® L as a broadcast or banded spray in the spring
prior to conifer bud break to lessen conifer injury potential.
WESTERN US
Rainbelt (areas of high spring rainfall): For best results, apply
as a broadcast or banded spray in the late winter or spring when
weeds are actively growing, but prior to conifer budbreak. If
application is made after conifer bud break, use directional spray
equipment to prevent contact with conifer foliage, as injury may
result.
Snowbelt (areas of low spring rainfall): For best results, apply
as a broadcast or banded spray in the fall before soil freezes and
after the final resting bud has hardened on the conifers. Or,
spring applications may be made after snow cover melts in
anticipation of rainfall prior to conifer budbreak. Weed control
results from spring treatments will be dependent on sufficient
rainfall following application to activate VELPAR® L.
USE RATES
The rates listed below are for broadcast application. For band
application, use proportionately less. For example, use 1/2 of the
broadcast rates when treating a 3-foot band where row spacing
is 6 feet.
