A good deal
By Nancy in Bonaire, GA on 03/17/2015
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.

Killing bermuda in centipede
By Ultracon in Georgia on 05/23/2016
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!

QWhat is "oil concentrate"?
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!
AWe 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.

QIs Hi-Yield OK for berries and conifer plantings?
I'd like to keep the grass away from our rows of blackberries and also plan to put in a windbreak of Eastern Redcedar, Mulberry, and American Plum and need to keep grass away from the seedlings. Safe?
AYes, the Hi-Yield Grass Killer Postemergence Herbicide is labeled to be used around fruits, vegetables, and ornamentals without fear of damaging these desirable vegetation.

QWhat types of oil can be used as a surfactant? I've used dish detergent in the past with other products.
AThe 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.
