Got one here, must be 40yrs old, dont know if its ever been used though.The Croptex Roguing Glove. Instead of physically pulling out wild oats you stroked each one with a dose of Roundup or whatever with an impregnated glove as you walked through the crop. I can imagine it is all to easy to accidentally touch the crop with the glove unless you were prepared to hold your arm up in the air all the time. Does anybody still use one?
