Like I said I have a 40 gal boom sprayer for a side by side, I have only been using a 1/2 gal in 40 gallon and I guess I need to use the whole gallon per sprayer full. I just didn't want to mix it to hot.

No it's just big spots and has grass mixed in. I have a 40 gallon sprayer that goes on a side by side because I mow rooughly 2 1/2 acres.

My only problem is white clover, I spray 2-4-D for my weeds and it kept the clover in check but I think its became ammune to it. Read where soil might be low in nitrogen but I really don't want to add I mow enough as it is. Any suggestions?

No. I would think the sweeter the better.
