When a systemic herbicide is applied to a weed, it must penetrate the leaf surface and move through the plants vascular system to the site of action within the plant. Several barriers exist within plants that hinder absorption, including the cuticle, cell wall and cellular membrane. When used as directed, herbicide additives can accelerate the rate at which the herbicide moves through these barriers. Herbicide additives can (1) reduce the surface tension of the carrier solution (2) improve retention and coverage of spray droplets on the leaf surface (3) increase herbicide absorbed rate (4) reduce the potential for herbicide induced plant stress and (5) reduce the need for over application of herbicides.
