PASTURE / RANGELAND
BRUSH CONTROL
DuPont™ VELPAR® DF is recommended for the control of
undesirable brush in pasture or rangeland.
APPLICATION INFORMATION
Apply VELPAR® DF 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® DF 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.
SPRAY EQUIPMENT
AND APPLICATION TECHNIQUES
Basal (Soil)-Mix 2 2/3 pounds of VELPAR® DF with sufficient
water to make one gallon of suspension and thoroughly agitate.
Apply the VELPAR® DF suspension with an exact-delivery
handgun applicator. This equipment delivers a thin stream of
predetermined volume when triggered. Apply the VELPAR®
DF suspension at the rate of 2 to 4 ml for each inch of stem
diameter at breast height. Direct the treatment to 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 the
VELPAR® DF suspension is needed per stem, make
applications on opposite sides of the stem. Do not apply more
than 1/3 gallon of the VELPAR® DF suspension per acre per
year. Intermittent agitation may be required to maintain the
VELPAR® DF in suspension.
USE PRECAUTIONS
PASTURE / RANGELAND
• Injury to or loss of desirable trees or other plants may result if
VELPAR® DF 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.
• 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%)
• Following mechanical cutting or clearing, allow stumps and
injured trees sufficient time to adequately resprout before
applying VELPAR® DF.
• Do not use VELPAR® DF on frozen soils.
• Weed and brush control results depend on sufficient moisture
to activate VELPAR® DF.
• When VELPAR® DF is applied as a basal soil treatment,
there is no restriction on grazing by domestic animals nor on
cutting surrounding vegetation for forage or hay.
• For broadcast pasture applications of VELPAR® DF, do not
cut treated vegetation for forage or hay nor graze domestic
animals on treated areas for 60 days.
