SPECIFIC WEED PROBLEMS
Control of Canada Thistle in Crown Vetch - DuPont™ VELPAR® L is recommended for control of Canada thistle in established stands of crown vetch on noncrop sites. Make a single application of
SPRAY EQUIPMENT
Apply VELPAR® L uniformly over the desired area using ground equipment or helicopter. Do not apply more than 3 gallons per acre of VELPAR® L by air.
Use enough water for thorough coverage. For ground application this is usually 25 gallons per acre. Higher volumes may be needed to obtain uniform application with handgun equipment. For aerial applications (helicopter only) this 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® L are used.
INDUSTRIAL TURF (UNIMPROVED ONLY)
VELPAR® L 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® L per year when weeds are actively growing.
WEEDS CONTROLLED - USE RATE
VELPAR® L effectively controls the following weeds at the rates shown in industrial turf (unimproved only). Use a lower rate on

*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® L 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.
USE PRECAUTIONS
INDUSTRIAL UNIMPROVED TURF
•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 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.
NON-CROP
BRUSH CONTROL
VELPAR® L is recommended for the control of undesirable woody plants in noncrop sites.
APPLICATION INFORMATION
Apply VELPAR® L 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.
