twice, allowing for sufficient root uptake of DuPont™ VELPAR® L. In the West, results may take one to two years in areas of low rainfall.
SPRAY EQUIPMENT
When applied as a liquid spray using water as the carrier, VELPAR® L may be applied by ground equipment or by air (helicopter only).
For ground application, use enough water for thorough coverage, usually a minimum of 25 gallons per acre. For aerial applications, use at least 5 gallons of water per acre and at least 5 gallons of water for every 1 gallon of VELPAR® L.
GRID APPLICATION
Apply undiluted VELPAR® L directly to the soil surface in a grid pattern using an exact delivery handgun applicator. This equipment delivers a thin stream of a predetermined volume. VELPAR® L should be applied during the period from hardwood bud break to early summer.
Selection of the rate per acre and grid pattern will depend on soil texture and woody plant composition. Use the lower rates on coarse textured soils and when the major component of the hardwoods are susceptible species. Use the high rates on

For
When treating brush that requires more than a single 4 ml application of VELPAR® L, apply subsequent applications equally spaced around the plant. If treating brush on sloped sites, apply most of the VELPAR® L on the uphill side of
the stem. If treating resprouts from brush disturbed by cutting or shredding, the rate of application should be proportional to the original tree size, not just the small regrowth of sprouts.
INJECTION
No Worker Protection Standard worker entry restrictions or worker notification requirements apply when this product is directly injected into agricultural plants.
Inject 1 ml of undiluted VELPAR® L through the bark of undesirable trees. Injections should be made at 4 inch intervals around the circumference of the tree. When using tubular injection equipment, inject near the ground level. When using the
USE PRECAUTIONS
SITE PREPARATION
Where burning is desired, burn the vegetation only after any residual brush has completely defoliated, at least twice, allowing for sufficient root uptake of VELPAR® L.
Following harvest, allow sufficient time for stumps and injured trees to adequately resprout before applying VELPAR® L.
