SPRAY EQUIPMENT

Apply VELPAR L by ground equipment or by air (helicopter only).

MIXING INSTRUCTIONS

For ground application, use enough water for thorough coverage, usually a minimum of 25 gal per acre. For aerial applications, use at least 5 gal of water per acre and at least 5 gal of water for every 1 gal of VELPAR L.

RELEASE - UNDILUTED APPLICATIONS

VELPAR L is recommended for hardwood suppression in conifer release sites.

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 when triggered. Apply VELPAR L during the period from hardwood bud break to early summer.

Selection of the rate per acre and grid pattern depends 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 fine- textured soils and hard-to-kill species.

SINGLE STEM (BASAL SOIL)

Apply undiluted VELPAR L to the soil with an exact delivery handgun applicator. Apply at the rate of 2–4 ml for each inch of stem diameter at breast height. Direct the treatment to the soil within 3 ft of the root collar of woody plants to be controlled. When treating large stems and when more than one delivery of VELPAR L is needed per stem, make application on opposite sides of the stem.

For multi-stemmed and low-growing brush that have stem diameters that are difficult to determine, apply VELPAR L at the rate of 2–4 ml per 3ft of canopy width. For tall, slender (columnar) brush types, apply 4–8 ml per 3ft of height. Base rate on whichever canopy dimension is greater (width or height).

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" intervals around the circumference of the tree. When using tubular injection equipment, inject VELPAR L near the ground level. When using the “Hypo-Hatchet” Tree Injector or a similar devise, inject at waist height. Treatment should be made in the summer. Woody species controlled include black cherry, oaks, and sweetgum.

IMPORTANT PRECAUTIONS

-RELEASE UNDILUTED

•Application of VELPAR L spots closer than 36" to conifer seedlings in their first season or directly up slope from these seedlings may result in injury or mortality.

•Use VELPAR L on seedlings in their first or fourth year and older. Injury may result from use on two and three year old seedlings where root growth is extensive but hardiness is lacking.
