Ortho WeedClear Lawn Weed Killer Ready-To-Spray, Kills Crabgrass and Dandelion, 32 oz.

I spot treated my backyard lawn that was full of Canada Thistles (literally hundreds) and I reside in Colorado. The Colorado State University Horticulture professor had also recommended Roundup for Lawns (Roundup is a brand name and this product doesn't contain any Roundup), Ortho Weed Be Gon Max + Crabgrass Control, and Weed Out with Q. I defaulted to this since it was readily available at my local box store. I spot sprayed the thistles and then came back after 14 days to get the remaining 5% that were stubborn and new growth. My buddy neighbor has been spot spraying for sometime (years) and it gets rid of his weeds including invasive thistle that happen to spring up. As the Horticulture professor says, just follow the directions on the label! I make sure to wear 14 mm thick rubber gloves, a 3M mask filter mask with a 3M 60921 filter (filters out organic herbicide vapors/particles) and eye goggles to minimize absorbing any vapors since I'm very sensitive to chemicals and I believe it's good to minimize exposure to these herbicides long term given the environment toxicity buildup these days. bottom line: it works on the pesky Canada Thistles that I've tried many different ways to deal with and this works! I spent hours researching through various University extensions, Youtube, etc.

[This review was collected as part of a promotion.] I have been using Ortho WeedClear for awhile now. I'm very impressed on how well it got rid of my weeds. It took less than twenty hours to see a difference.I found it very easy to use. All you do is add two and half ounces to every gallon of water in a sprayer bottle. I did this once a month and kept the weeds away. This Ortho WeedClear gets rid of over 200 kinds of weeds to the roots. If you want to get rid of your weeds fast and effectively I would recommend the Ortho WeedClear.
