WEEDS CONTROLLED
VELPAR® DF is recommended for the control or
suppression of the following species in release sites:
* Suppression – a visible reduction in plant population and/or plant
vigor as compared to an untreated area and generally not accepted
as control.
FORESTRY
IMPREGNATION ON DRY BULK
FERTILIZER
VELPAR® DF is recommended for impregnating or coating
dry bulk fertilizer to be applied on forested sites for the
establishment or release of conifer plantations (except
longleaf pine) as specified on this label.
PLANTS CONTROLLED
Fertilizer impregnated with VELPAR® DF is recommended
for the control and suppression of the weeds and brush
identified for the specific applications on this label. Consult
the appropriate segment of this label to determine the
appropriate rate of VELPAR® DF to be applied per acre.
Apply this amount of VELPAR® DF to the volume of
fertilizer to be applied per acre.
IMPREGNATION EQUIPMENT
To impregnate or coat the fertilizer use a system consisting
of conveyor or closed drum used to blend dry bulk fertilizer.
IMPREGNATION INSTRUCTIONS
To impregnate dry bulk fertilizer with VELPAR® DF, mix
the amount as prescribed above in a sufficient quantity of
water to uniformly coat the desired amount of fertilizer.
Suspensions of VELPAR® DF will require thorough
agitation.
Direct the spray nozzles of the impregnation equipment to
deliver a fine spray of the mixture toward the fertilizer for
thorough coverage while avoiding contact with mixing
equipment. The use of a spray pattern indicator may be
beneficial to visually determine the uniformity of impreg-
nation.
Uniform impregnation of dry bulk fertilizer may vary. If
absorption of the spray is not adequate, the use of an
absorptive powder or additive, such as “Microcel E” or
“HiSil 233”, may be required to produce a dry, free flowing
mixture.
Apply the fertilizer as soon as possible after impregnation
for optimum performance. Impregnated fertilizer may
become lumpy and difficult to apply following storage.
Diammonium phosphate, potassium chloride, 16-16-16 and
24-4-4 have been successfully impregnated.
APPLICATION EQUIPMENT
Applications of impregnated fertilizer may be made by
ground equipment or by air (helicopter or fixed wing).
Accurate calibration and patterning of the equipment is
essential for uniform distribution of the impregnated
fertilizer on the soil surface.
USE PRECAUTIONS
IMPREGNATED FERTILIZER FOR
FORESTRY
• If fertilizer materials are excessively dusty, use a suitable
additive to reduce dust prior to impregnation. Application
of dusty fertilizer which has been impregnated may result
in off-target drift and injury to desirable vegetation. Such
