## Overview

Pentra-Bark Penetrating Surfactant is a 32oz solution designed to enhance systemic pesticide and fertilizer uptake by woody plants through lenticels in the bark. Registered in California for exclusive use with Agri-Fos against Sudden Oak Death, it significantly reduces treatment time and chemical use by delivering active ingredients directly into the tree’s vascular system via trunk application. Proven effective since 2007 for controlling Emerald Ash Borer, Pentra-Bark offers a safer, more efficient alternative to traditional spraying or soil injection methods.

## Description

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. 32oz/1 Quart container.
