    Details

     
    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.
