I find that the sweet spot for weed applications is between 20-40 gallons per acre. When going after hard to kill weeds observe the Bayer recommendations concerning surfactants/adjuvants. Celsius has been a very good product for my situation. However, it has been used under certain parameters. The concept being make as much of that 2.4 grams per 1000 sq ft stick to the target weeds and penetrate into those weeds. High or low volumes applied as widely scattered large droplets do not work the same as up to 60 gallons per acre applied as closely spaced droplets. This is for fungicides, but I think it also applies to herbicide applications. I like the AI tips on either a single nozzle wand or small boom for residential turf applications. It is a good compromise between coverage and drift control.
