best sprayer for glyphosate-like chemicals?

philosopher(Zone 5a WI)September 10, 2011

hi--i just spent half a day using a tiny old plastic pump sprayer to spray glyphosate between my lannonstone in the backyard. without getting into the use of glyphosate (i know there are passionate emotions about it--note that i bought a generic), can someone please recommend the best tool to effectively spray this stuff in a targeted manner? my right arm is aching from pumping that plastic contraption about 6 million times.

thank you so much in advance--

Well, I use whatever pump sprayer is convenient. Currently I have one that actually says Roundup on it. I often have it set so the spray pattern is fairly narrow, and for cracks, keep it close to the ground.

The spray nozzle itself is important. You don't want the kind that makes a fine mist, because Glyphosate will kill pretty much any plant, broad leaved or narrow leaved. So use something that has minimal spray drift. You might consider removing the spray nozzle altogether, and just dribble the stuff into the cracks between flagstones or whatever. Avoid spray drift with glyphosate.

Incidentally, Glyphosate does not work as a pre-emergent weed killer. It only works on growing plants.
