Basal bark applications of herbicide with new ultra-low pressure dispenser
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.
