NC Iowa | what is a good gpa and nozzel to use for roundup? i have xr8004 and used 15 gpa last year. didn't get the results i was expecting. i think i need smaller droplet size for better coverage. with the 04's and 15gpa, i need to keep my speed at 7mph to get sprayer up to 35 psi. if i have to slow down much, pressure will drop to around 25. that is great for reducing drift, but i think it reduced coverage too much.
would i get better coverage/results if i.
A. up the gpa to get greater pressure.
B. go to a different style 04 nozzel
C. go to a smaller nozzel
D. both A and B
