You don't need that much water. Ric is right. Boom sprayers apply less water and more chemical. Why not go with about a third of a gallon per thousand--like a Z-spray?
If you insist on 2 gal per thousand--easy choice--go slow--use only 3 nozzles--or get a bigger pump.
Naturally your tank will run out quicker--and you will spend a lot of time driving back to the truck, refilling the tank and mixing new chemicals.
Suit your speed to the situation. Herbicides and insecticides 4 mph. Some odd product that requires four times as much water per thousand--just go 1 mph.
