DuPont Authentication Velpar H - 65396 - Manual (Page 24)

BROADCAST
Apply 2 to 4 gallons of DuPont™ VELPAR® L per acre as
coarse spray by ground equipment or 2 to 3 gallons per acre
by air (helicopter only). Use enough water for thorough
coverage. For ground equipment, usually a minimum of 25
gallons per acre. For aerial equipment, usually a minimum of
10 gallons per acre. Higher volumes of water may be needed
when water temperatures are cold or the higher rates of
VELPAR® L are used.
BASAL (SOIL)
Undiluted - Apply VELPAR® L undiluted with an exact-
delivery handgun applicator. This equipment delivers a thin
stream of a predetermined volume when triggered. Apply
VELPAR® L at the rate of 2 to 4 ml for each inch of stem
diameter at breast height. Do not exceed 4 gallons of
VELPAR® L per acre per year. 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
applications 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 to 4 ml per 3 feet of canopy width. For tall,
slender (columnar) brush types, apply 4 to 8 ml per 3 feet of
height. Base the 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.
Diluted - Mix one gallon of VELPAR® L with 5 or more
gallons of water. Apply 2 to 4 gallons of VELPAR® L per
acre. Direct the spray to the soil in a serpentine pattern so that
the swath on the soil is 6 to 12 inches wide at the base of the
brush. Swaths should be 2 to 4 feet apart.
BRUSH CONTROLLED - USE RATE
2 – 4 Gallons/Acre
* Suppression – a visible reduction in plant population and/or plant vigor
as compared to an untreated area and generally not accepted as control.
† For Cholla cactus (tree-type cactus) apply VELPAR® L at the rate of 4
milliliters (mls) of product for plants up to 2 feet tall. Apply 8 mls of
product for Cholla cactus plants between 2 and 6 feet tall. For plants
taller than 6 feet, apply 4 mls for each additional 2 feet of height.
When treating plants it is desirable to make applications equally spaced
around the plant.
USE PRECAUTIONS
NON-CROP
• Injury to or loss of desirable trees or other plants may result if
VELPAR® L is applied or if equipment is drained or flushed
on or near desirable trees or other plants, on areas where their
roots may extend, or in locations where the chemical may be
washed or moved into contact with their roots.
• Application spray drift may injure desirable plants.
• Poor weed and brush control may result from the following:
–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%).
