DuPont Authentication Velpar H - 64953 - Manual (Page 18)

USE PRECAUTIONS
RELEASE - GRID & SINGLE STEM
• Application of DuPont™ VELPAR® DF 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® DF 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® DF is recommended for controlling herbaceous
weeds where the following species are grown:
EASTERN US
WESTERN US
APPLICATION INFORMATION
EASTERN US
Apply VELPAR® DF 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® DF.
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. Use the higher rate range for the harder to
control (*Suppression) weeds listed in the table below.
