Hi-Yield Weed Killers 31134 Editorial Review
The Hi Yield 16 Oz Grass Killer is a highly selective herbicide that is specifically designed to kill broad-leafed grasses. It has been successfully used to eliminate Japanese Stiltgrass and Bermuda Grass, while not affecting other plants or vegetation in the area. Users have found it to be effective in killing grass in vegetable gardens, as well as in soybean food plots. It is important to note that this herbicide may not be effective for certain grasses like crabgrass. One user highlighted that it took over a week for the grass to start turning yellow and die, but it ultimately stopped growing soon after spraying. To ensure optimal effectiveness, it is recommended to mix the herbicide with a surfactant so that it sticks to the grass blades. However, there are some negative reviews from users who did not experience any success with this product. They mentioned that even after multiple applications, the grass they sprayed did not die. Some users expressed disappointment with the limited effectiveness of this herbicide, as it only targets specific grass types and does not kill other common weeds. Overall, the Hi Yield 16 Oz Grass Killer is best suited for targeting specific broad-leafed grasses and may not be suitable for eradicating other weed varieties.
