DuPont Authentication Velpar H - 65396 - Manual (Page 21)

2 3/4 – 4 1/2 Pints/Acre
* Suppression may result with some of the giant (larger) smutgrass
species.
Suppression – a visible reduction in plant population and/or plant vigor
as compared to an untreated area and generally not accepted as control.
SPRAY EQUIPMENT
Apply DuPont™ VELPAR® L uniformly over the desired area
using ground equipment only.
For ground application, use enough water for thorough coverage
usually a minimum of 25 gallons per acre. The use of a
surfactant may increase the potential for bermudagrass or
bahiagrass injury.
USE PRECAUTIONS
BERMUDAGRASS / BAHIAGRASS
• Use VELPAR® L only in stands of bermudagrass and
bahiagrass established for at least one year. Do not treat newly
sprigged or sodded areas.
• Some temporary discoloration of the bermudagrass or
bahiagrass may occur after application.
• Treatment of mixed pastures containing forage species other
than bermudagrass or bahiagrass may result in injury or
mortality to the other forage species.
• Injury may result when desirable grasses are under stress from
drought, insects, disease, cold temperature, or poor fertility.
• 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.
• Severe crop injury may occur if applications are made on
gravelly or rocky soils, thinly covered subsoils, or soils with
less than 1% organic matter.
PASTURE / RANGELAND
BRUSH CONTROL
VELPAR® L is recommended for the control of undesirable
brush in pasture or rangeland.
APPLICATION INFORMATION
Apply VELPAR® L from late winter through summer, pre-
budbreak until new growth hardens off.
In areas where the soil remains frozen during the winter and
spring rains are usually inadequate for soil activation, a fall
or winter treatment may be applied before the soil freezes.
For rates needed to control the species below, see the
Forestry - Release, Use Rates section.
BRUSH CONTROLLED
VELPAR® L is recommended for the control or
suppression of the following brush species in pasture and
rangeland:
* 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.
SPRAY EQUIPMENT
AND APPLICATION TECHNIQUES
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 2–4 ml for each inch of
stem diameter at breast height. Do not exceed 1/3 gallon of
VELPAR® L per acre per year. Direct the treatment to the soil
within 3 inches 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.
