Pentra-Bark
penetrating surfactant will take water soluble insecticide, fungicide,
pgr, and fertilizer into the vascular system of the tree for
translocation into foliage or roots, which eliminates the need to spray
foliage, soil drench, bark inject, or pressure inject into soil.
Pentra-Bark works because: 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. California registration #83416-5001-AA
