Trying to understand the difference in amounts of AI and water used to cover an acre using a CL gun/skid vs PG or other ride on. Some label's will tell you to use 20gal water or more per acre. How does this work when using a PG? and why?
All the water does is allow for uniform spreading of the pesticide--water has no other value. We hate water--it kills time and profit.
Studies were done at NCSU which showed more weed control activity of glyphosate with no dilution--spraying straight in a Herbi controlled droplet appicator.
A lot of water/solution is needed in a hand hose/hand gun operation as this is a gross method of application and not a percision one. One actually wonders how such an application does not violate label restrictions on overlap and spot rate per ac. maximums.
I think i unserstand your question, so try this,....It comes down to application speed, ride-ons have faster ground speed than walking (as you know) so thats why you have the AI diluted so much with a skid sprayer, and more amount of AI (hotter mix) in a ride-on, so you will have the same amount of AI in 1k regardless of whether you hand spray with a skid or ride it with a PG or whatever brand. It is just two diffrent styles of application of chemicals. Hope this helps...????

Which is why I do not have a lawn application gun in the truck or attached to any of my power sprayers. All of my lawn applications are sprayed through a boom or a single nozzle wand with the proper fan tip for the spray volume required. Application volume can range from 20-160 gallons per acre.
There is a big difference in glyphosate effect in varying water volumes, provided sufficient and accurate coverage of target weeds is attained. I get the best effect from a 20-40 GPA volume. Note that I am normally targeting tall weeds and rank overgrowth. Not small seedling weeds in a flat field. There, I would try as low as 10-20 GPA.
