DuPont Authentication Velpar H - 65190 - Manual (Page 21)

APPLICATION INFORMATION
Make a single application of DuPont™ VELPAR® DF per
year when weeds are actively growing.
WEEDS CONTROLLED - USE RATES
VELPAR® DF effectively controls the following weeds at the
rates shown in pastures. Use a lower rate on coarse-textured
soils (sand to sandy loam). Use the higher rate on fine-textured
soils (clay loam to clay) and on soils high in organic matter.
9/10 - 1 1/2 Lb/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 VELPAR® DF 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 - PASTURE
• Use VELPAR® DF 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® 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.
• 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.
• 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.
PASTURE / RANGELAND
BRUSH CONTROL
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

suppression of the following brush species in pasture and
