How does PENTRA-BARK work?

All woody plants have microscopic openings in the exterior protective bark periderm layer called lenticels. These lenticels are functionally used for plant transpiration and pressure regulation.
Lenticels connect directly to the plant’s annual spiral openings or vascular metabolic transport system contained in the plant’s cambial phelloderm.

When PENTRA-BARK is applied to the woody bark periderm in combination with systemic pesticides it opens the lenticels and enables movement through the lenticels into the plant’s vascular transport system. 

tree and shrub insect control

In the trial below, an inert dye was mixed with 3 oz. of PENTRA-BARK per gallon of water and applied onto the tree trunk with the basal bark application method.

The tree was dissected and examined 7 days after application. The inert dye had penetrated into the center of the tree within 7 days and the inert dye had also been transported throughout the tree’s vascular system as evidenced by the dye being found 24 feet up into the canopy of the tree. Translocation of systemic pesticides primarily occurs in the cambial zone.

organic insecticide spray

How much is spray solution required to treat a tree generally with the basal bark application method, applied from ground level to 5 feet up the trunk circumference?
How much PENTRA-BARK should I use per gallon of spray?

PENTRA-BARK should be used at 1% of spray volume solution
or 3 oz. per gallon of spray solution
Approximate solution volume required for treatment per inch of DBH

DBH Smooth Bark Rough Bark
6'' <1 pint 1 pint
12'' 1 quart 1-1/2 quarts
18'' 2 quart 2-1/2 quarts
24'' 2-1/2 quarts 3 quarts

Apply solution until saturation run-off occurs (DBH= diameter measured at 4.5 feet from ground level) Rough Bark trees require more solution for treatment.
