SPECIFIC WEED PROBLEMS
Control of Canada Thistle in Crown Vetch - DuPont™
VELPAR® DF is recommended for control of Canada thistle in
established stands of crown vetch on noncrop sites. Make a
single application of 1 - 1 2/3 lb of VELPAR® DF from late
spring through mid-summer, when thistle is actively growing
prior to flowering. Do not use a surfactant. Some discoloration
of the crown vetch foliage may occur after application.
SPRAY EQUIPMENT
Apply VELPAR® DF uniformly over the desired area using
ground equipment or helicopter. Do not apply more than 8 lbs
per acre by air.
Use enough water for thorough coverage. For ground
application this is usually a minimum of 25 gallons per acre.
Higher application volumes may be needed to obtain uniform
application with handgun equipment. For aerial applications
(helicopter only) this is usually a minimum of 5 gallons per
acre. Higher volumes of water may be needed when water
temperatures are cold or the higher rates of VELPAR DF are
used.
INDUSTRIAL TURF
(UNIMPROVED ONLY)
VELPAR® DF is recommended for selective weed control in
established stands of bermudagrass and/or bahiagrass in noncrop
areas.
APPLICATION TIMING
Make a single application of VELPAR® DF per year when
weeds are actively growing.
WEEDS CONTROLLED - USE RATE
VELPAR® DF effectively controls the following weeds at the
rates shown in industrial turf (unimproved only). 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 is not recommended.
