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.
MIXING INSTRUCTIONS
Use enough water for thorough coverage. For ground
application this is usually a minimum of 25 gal 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 gal per acre.
Higher volumes of water may be needed when water temper-
atures are cold or the higher rates of VELPAR DF are used.
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. 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
Partial control may result with some of the giant (larger) smutgrass species.
SPRAY EQUIPMENT
Apply VELPAR® DF uniformly over the desired area using
ground equipment only.
MIXING INSTRUCTIONS
For ground application, use enough water for thorough coverage
usually a minimum of 25 gal per acre. The use of a surfactant is
not recommended.
USE PRECAUTIONS
- INDUSTRIAL UNIMPROVED TURF
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 discoloration of the bermudagrass or bahiagrass may
occur after application.
Injury may result when desirable grasses are under stress from
drought, insects, disease, cold temperature, or poor fertility.
Severe turf injury may occur if applications are made on
gravelly or rocky soils, thinly covered subsoils, or soils with
less than 1% organic matter.
VELPAR® DF is recommended for the control of
undesirable woody plants in noncrop sites.
APPLICATION TIMING
Apply VELPAR® DF from late winter through summer,
prebud break 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.
WOODY PLANTS CONTROLLED - USE RATE
VELPAR® DF is recommended for the control or
suppression of the following species. Use 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.
