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.
The original poster never said what type of product they we planning to spray. There are a bunch of products I wouldn't consider spraying less than 2 gal /1000.
I have a small tank with a "2.2 GPM" pump on it. With the bypass turned off, I can't get more than 1 GPM out at the nozzle, but I used a skinny hose.
