Pentra Bark Surfactant quart (32 oz)

Pentra-Bark is a professional bark-penetrating surfactant designed to improve the absorption and translocation of pesticides, micronutrients, fungicides, insecticides, and plant growth regulators through woody bark surfaces. By opening microscopic bark lenticels, Pentra-Bark allows spray solutions to move directly into the plant’s vascular transport system for improved uptake and more effective systemic movement throughout the tree or plant. Trusted by arborists, nursery professionals, and vegetation managers, Pentra-Bark enhances basal bark and trunk spray applications while reducing drift, chemical trespass, and applicator exposure. The product has been university tested and demonstrated effective penetration into xylem and phloem tissues when used with systemic pesticide applications. Pentra-Bark is highly recommended with basal bark applications of Safari, Denote and Zylam and is widely used in tree health care, ornamental management, and systemic trunk treatment programs.
