using hay guard hay preservative with a small square baler

not sure if there is a topic for this already or not i did a few searches and couldn't find any.  i'm

 using a preservative called Hay guard. the dealer im buying it from said based on my bales per minute it needs to by applied at .01gpm at 20 psi. the baler I have came with a preservative sprayer with a 1.8gpm pump, 1/2" return deverter line and 1/2" spray bar with 2 applicator tips. I reduced the spray bar to 1 applicator tip but the lowest tip i can find is .11 gpm. has anyone found a tip that is smaller than this? or have any suggestions on a better way to apply hay guard?

 

thanks
