Hi-Yield (31134) Grass Killer Postemergence Grass Herbicide (8 oz)

Great

Works great& price

Very disappointed. I sprayed several areas in the heat of the day at 79 years old and not only did it not kill the grass but it looks like it fertilized it. I even added surfactant for even coverage. Didn’t help. I thought maybe it was too good to be true. Guess what? It was…….

I didn't know that you could kill bermuda grass in a centipede lawn, without using a non selective herbicide (eg like Roundup). This stuff works, but probably requires two applications. The main ingredient (sethoxydim) appears to have no effect on the centipede. But as always, read the label, follow the instructions.

This works great. Last a long time.

Good product for removing invasive grass species. For anyone who has had slow results or only seen their grass yellow but not die, suggest adding 1/2 of one percent Glyphosate to the mixture. The Glyphosate really turbo charges this product and is such a low percentage that non-grasses are not likely to be hurt. I sprayed Japanes Stiltgrass that had ferns mixed in and the grass died but the ferns were fine.

This herbicide is highly selective - only kills broad leafed grasses. I've been using it to eliminate Japanese Stiltgrass in some wooded property we own. NOTHING else is affected by it, not even the patch of ferns that we have repeatedly sprayed to kill the stiltgrass growing among them. I've heard people suggest a more "natural" weed killer like vinegar-based mixes, but that would kill EVERYTHING. Personally, I'm trying to save everything but the stiltgrass. I strongly recommend mixing with some kind of surfactant so that the herbicide will stick to the grass blades.

Didn't kill the grass like it said it would. Tried it several times and no difference.
