Hi Yield 16 Oz Grass Killer | Fluazifop-P-butyl selective herbicide - 16 oz post-emergent grass control over desired plants - DIY landscapers

These photos have been taken one week from application and I will wait until the third week to see if a second application is required . Some grass has browned, some has turned purple, and there is some completely green and unaffected but it has only been a week.

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.

I used this stuff at the appropriate rate to kill bermuda grass in my iris bed and it killed my irises. The bermuda grass is still thriving, it did nothing to it. The company is only refunding me for the product,( $25.97). It clearly states on the label that it can be used over irises. Now they are all dying. I want to cry. Hundreds of dollars worth of beautiful irises. Please do not use this product on your irises.

We have a problem with Bermuda grass in our flower beds. This product works well to control Bermuda grass. When I ordered it I did not realize that I would also need to have crop oil for this to work well. The crop oil helps the product to adhere to the grass. Without the oil the product just evaporates too quickly to be effective.

Products works to kill crabgrass with very little damage to Monkeygrass

I purchased this because when seeing last autumn a bunch of seed ended up in my garden. An AI search result recommended this product. Upon receiving it the instructions made it appear like it was intended for weed type grasses as opposed to lawn grass (in this case, tall fescue). I tried it anyway. Within a few days all the fescue in the garden was dead and the vinca was fine!

Not what I was expecting

I used Hi-Yield 16 oz Grass Killer specifically to get rid of Bermuda grass, and it did exactly what I needed it to do. After application, the Bermuda grass started to yellow and die off as expected, and it didn’t take long to see real results. It’s easy to mix and apply, and a little goes a long way. I like that it’s effective and saves me from having to repeatedly pull or dig up stubborn grass that keeps coming back.
