About the scythe,<p>I had a conversation with someone the other day and they said it muffles the overall effect of the roundup. <p>What I mean by this is that the roundup, needs to be translocated to the root system to kill the weed completely. I guess, because the scythe kills the plant so quick, it shuts down and the roundup doesn't have time to fully activate. Heard that,though the area dies quick, REAL QUICK, it has a tendency to come back later on and needs a second app. <p>It makes sense when you think about how roundup works and how scythe stops it from moving. If the plant dies on the top, the roots may still be alive, but the roundup only has had time to work through a small amount of the leaf/stem and won't reach the roots because the plant is no longer sucking it in from the top.<p>Kind of like pulling a weed by hand but only ripping the top off. Later on, it always seems to come back<p>Seems like, that unless your in a area that requires immediate results, straight roundup is the best way to go.<p>Anyfeed back on is?<p>And yes, it STINKS.<p>steveair<p>
