If the trees were killed or damaged, that is chemical trespass. I consider conventional flat fans unusable for herbicides except in perfectly still conditions. In my location that is a rare event and those perfectly still conditions are normally accompanied by weather conducive to inversion or volatility.
Could you give me a crash course on air inducted nozzles and non air inducted nozzles? I haven't ever used anything except a chemlawn gun. I agree with you. I would rather turn a spray job down than to try and do it and end up doing it incorrectly where drift damage occurs, etc.
