Are you talking about herbicide? What speeds do you want to go?
Like Twix says, droplet size is your primary means of controlling drift. Larger droplets mean less drift, but also poorer coverage. So it's a trade off. Higher PSI means smaller droplets and more dift-able fines. If you need to make a pass along an acreage, consider dropping the PSI a ways. Say to 50 or 60 (or lower if you need to). And slow way down.
Going to a bigger nozzle will make bigger droplets, but if you just crank up the pressure then your duty cycle is going to drop. I don't know what the ideal duty cycle is, but I prefer to keep it above 70% as much as I can.
Wilger has a nice tip wizard online that can let you choose nozzles for the speeds, volume, and droplet size you want. Or you can put your current nozzle type in and find out what droplet size you're likely to get at different PSIs. https://www.wilger.net/tip-wizard/
or there's an app for iPhones and Android.
I must just be a slow operator, but I have MR03s for 5 gpa, SR06s for 8-10 gpa, and right now have 08s for 14-20 gpa (too slow). I need to pick up a set of 10s, probably ER 10 to get the droplet size I am used to.
