Our new dispenser works great for doing basal bark applications of herbicide.
Basal bark treatments involve the application of an ester herbicide in an oil carrier to the bark of a tree. We actually dial the pressure in at 2 psi – i.e., very low! This produces a narrow stream of herbicide that can be precisely applied even to very small stems such as the one shown below. This reduces off-target harm and reduces herbicide waste. We posted a YouTube video that goes into greater depth.
