Thank you so much !!! I am really glad I bought this weed killer !!! MP Review: easy to use & it works - I stopped paying $ 200+ monthly for our landscaper. (weed control was an additional $ 300 every 6 months!) I took on the landscaping myself. and, one of those items was weed control. I noticed that one of my neighbors did his 6-month weed control himself, and I asked him what product he uses. It was this Killzall weed control. I started it last spring and the results were extremely satisfactory. I didn't see any weeds until about a week ago. so, the 6 month clock was ticking, and I re-applied Killzall again. This goes on very easily. I bought a manual 1 gallon sprayer from desertcart, and this is just so easy to apply. It works so well! ## Features - Controls unwanted weeds and other vegetation on non-crop/no-vegetation areas.

My dads property stays wet, and this is the only thing I’ve found to work. The price is a little out outrageous now and getting worse. The only problem I have is that running vine’s always grow in place of the grass.
