Hi-Yield Grass Killer is a post-emergent selective herbicide that kills annual and perennial grasses in ornamental landscapes and desirable plants. Can also be used on trees, shrubs, and ground covers. Hi-Yield Grass Killer stops grass from growing within 2 days of application.
For best results you should add a surfactant to your solution to help the product stick to the target weeds and grass.

I used this product once last summer and it stopped my Bermuda grass from growing within my Centipede. The runners appear green when runner stalks were broken even though they have not grown any...so I am going to use this again in a few weeks to prevent any spring growth. So far, it is the only thing I have found to eliminate the Bermuda.
Ordered Hi-Yield grass killer on Monday and received it on Thursday. I had a number of Crab Grass patches in our lawn and used it as a spot spray on those patches. Follow the label and add a spreader sticker oil. It has been several days and the Crab Grass appears to be killed and I am satisfied with the product.
This stuff really works when used with the surfectant! After one application, the bermuda has stopped growing and is dying. The centipede is untouched! A second application will be going on in a week or so. This is really, really, good stuff and worth the $$!!!!! Be sure to get the surfectant as well to mix them together. A solution to my problem after years of digging and pulling!
Why is it not in "Hi-Yield" grass killer or why is not stated on front of label that it will be needed? Frustrating to drive one hour home to read label and then find out!
We are not the manufacturer so we cannot comment on why it is not on the label. When an herbicide calls for oil, it is referring to a surfactant. Surfactant helps the herbicide stick to the waxy coating of the weeds and lawn you are applying it to. It improves the effectiveness of herbicides greatly.
Can I use Hi-Yield Grass Killer safely on the grasses growing in my iris plants?
Hi-Yield Grass Killer is a post-emergent selective herbicide that kills annual and perennial grasses in ornamental landscapes and desirable plants. Iris plants are tolerable per the product label. You will use 1 fl. oz. per gallon of water and add a surfactant such as Hi-Yield Spreader Sticker.
What types of oil can be used as a surfactant? I've used dish detergent in the past with other products.
The manufacturers normally recommend that you use some type of certified surfactant with their products like the Non Ionic Surfactant. With a Glyphosate product like the Hi Yield Grass Killer Herbicide, you would need 1 tablespoon per gallon of mixture. Please let us know if you have any other questions.
Will the Hi-Yield Grass Killer Postemergence Herbicide harm asparagus or chicory
Plan to use on garden and wildlife food plots
The product label for the Hi-Yield Grass Killer Postemergence Herbicide does state it can be safely applied to asparagus and several other types of vegetables. We have contacted the manufacturer to ask about chicory and wild food plots as those are not on the label and will let you know what we find out
