I use a WAND instead on a gun. It is just a Ball valve shut off on a 54 " pipe with a crook in it so I am shooting straight at the ground. I have even sprayed in High winds because I can hold it so close to the ground with very large droplets. By just cracking the ball valve I can cut down the flow to a trickel and do very close in spraying.
