My suggestion is to get a sprayer with a 120' boom so that you match 3 planter passes.   Then slide the rows on your planter beside your "wheel tracks" each out 1' to make a pair of 22" rows to ride in with the sprayer.

380 tires work great in a 22" row.     And once your eyes are trained to it, it is very very easy to pick out the wide rows.


Been doing that for years with a 90' pull type and an 18 row 20" planter (30').
