I've been researching the PG ride-on for awhile and took the next step today and went out to Lesco to ask some more questions. In the course of our back and forth he stated that only a herbicide labeled as low volume (of which they have 2 options, Red Zone and Momentum) could "legally" be used with the PG but that pretty much everyone used their 3-way herbicides and took their chances with the State. I don't know that I've seen this issue addressed in any previous threads re. the PG's. Any information would be appreciated.
