How do you calibrate the rate? I thought of doing that but got scared of not knowing the rate it would put out. what type of hose end sprayer do you use?Originally posted by Grassmechanic
This was brought up a short time ago. Do a search on the subject. But in short, no, I do not use R-up in my sprayer. I use my sprayer as a water source and hook a hose-end sprayer to it and add the R-up concentrate to the hose end sprayer.
Phil - I use an Ortho Dial-A-Spray. It has graduated settings on it. Pour Round-up in the jar, dial to your setting (amt. of chem/gallon) and spray away.Originally posted by philk17088

Russ - glad to help. It actually dawned on me one day as I was going through the hassles of rinsing and cleaning my tank at the golf course I was working at back in the 80's. I've been doing it ever since.Originally posted by Russ
that hose end sprayer is a great tip. Thats the reason I come here. Simple and and a no brainer but I would have never thought of it without your input. I used it on 11/K a couple of weeks ago. Saved tons in clean up rinse and neutralizer. No mater how long or how much ya know, somebody(like you) always knows how to do it better. Thanks again
On my sprayer, it's around 100 psi at the gauge. I had to mess around a bit with the pressure to get a nice, even spray. The pressure isn't really important, other than to get an even spray, because the venturii in the hose-end sprayer meters the chemical out in xx/ounces per gallon. Experiment with water only in your driveway to get it the way you want.Originally posted by philk17088
Another question. What pressure?
You are correct and after about 3 full tanks you can spray ornamentals with no worries.Originally posted by Ric
I am going to go aganist the grain here and say it is ok to spray all three. The only rules is don't spray ornamental with the same sprayer. I am not going to get into a this won't hurt that thing. My bottom line is if you empy the tank, the next mix will be so low a constrate it will not hurt turf. I use seperate tanks because I am spraying them every day. Up north you don't have to spray as much as we do. I think you can get away with one turf tank, sure keep it clean but don't sweat it. 2-4-D is the worst for tank residual.
