best sprayer for glyphosate-like chemicals?
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--
