* 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.

Apply DuPont™ VELPAR® L uniformly over the desired area

F
or 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
g
r
a
velly or rocky soils, thinly covered subsoils, or soils with
less than 1% org
anic ma
tter
.
