[AT] Garden question

[Greg Hass]

My garden is where the old cattle yard was. Things grow great and the 
soil is easy to work; I use my farmall cub to work and cultivate the 
garden, however, once things get a little big weeds take over. My back 
won't allow much hand weeding and weeds get a couple of feet high in a 
short time. I have seen, at least in Agri-Supply,  a stick like thing 
with a 6 inch rope wick thing on the bottom and you put round-up in it 
and swipe the weeds and it is supposed to kill them and not your plants. 
Anyone ever used them and do they work or is it just more money down the 
drain.
