Herbicide use in the forest is on the uptick as private and public landowners get serious about controlling exotic invasive plants. The most common type of herbicide treatment is spot treatment of individual plants, usually by an applicator who is using a backpack sprayer. The basal bark method and cut stump method are also used as a spot treatment, as is the hack-and-squirt method (especially for ailanthus control). At the more intensive end of the scale are some contractors who mow heavy infestations of non-native invasive brush and apply herbicide to the cut stumps as they go. It is not known if any other more intense spraying, ground-based broadcast spraying, or aerial spraying of herbicides takes place in New Jersey, or is envisioned to take place in the future.
