Review: Effective on Silverleaf Nightshade and Other Broadleaf Tough Weeds - We live on just over an acre in central Arizona and moved into an area that is infested with Silverleaf Nightshade (Solanum elaeagnifolium, or aka Horesenettle) which is a toxic, tough, nasty, perennial weed from the Nightshade family, poisonous to both humans and animals if ingested, especially the numerous yellow berries it produces. It spreads quickly through an extensive tuberous and woody root system and has sharp tiny painful spines covering the entire stems and even leaves. It is extremely difficult to control and requires numerous treatments and vigilance to eradicate as it pop up everywhere from the central sytem. This Ortho "super concentrate", which works down through the root sytems of these broadleaf obnoxious weeds (and many others), is one of the few effective controls I have found. Glycophosphate-based (the basic "Roundup types", etc) weed killers will only give temporary control. It is cost-effective compared to the pre-mixed stuff, especially if you have large areas to cover. Be careful when using it as it contains 2,4-D and Dicamba (3,6-dichloro-2-methoxybenzoic acid). Do not use near any sensitive or wanted plants when temperatures are above 80 degrees, or even a slight breeze, as 2,4-D and Dicamba will vaporize and drift onto them, damaging and even killing them as well. I know, as the volatilization killed a few of my young grapevines when I used another weed killer (Crossbow) containing 2,4-D when it was 95 degrees. This applies to weed killers carrying Triclopyr as well, so read and adhere to the instructions and BE CAREFUL.
Review: Kills all weeds FAST! - It seems every weed season some products vanish and others arrive on the scene. This version of Groundclear concentrate had pretty good reviews so I gave it a try. Chasing weeds for months on end is no fun so if I can find something that works fast and keeps my yard weed free I happily go all in. It's a killer is all I can say. There wasn't a weed that I sprayed that didn't die in 48 hours and the vast majority were dead in a couple of hours. Whatever is in here it makes things get dead fast. I have a patio, long walkway, and a very large area filled with river rocks that all seem to be heaven for weeds. They quickly became weed free for me using this stuff. The price on this jumps around A LOT so we'll see what happens this year but if it remains affordable, it will be my go to once again.

Did a pretty good job of clearing out brush. Not as strong as the tractor supply ground clear but it did well enough.
