Works as advertised
By Matthew on 07/13/2016
Was using Trimec 992 before I bought this. The Trimec didn't touch the Wild Violet in the yard but this certainly did. It is a lot more expensive than the Trimec but it finally killed the tough weeds. Trimec is fine for most weeds and usually needed a second application to kill them all but this worked great on all the weeds and no need for a second application. Works as advertised and worth it for the cost.

Better than anything at the big box store
By Stephen on 05/11/2019
In my first application to wild violets I saw the plant wilt far more than any other broadleaf spray from the box stores. I have no doubt 4 speed will significantly slow the growth of wild violets with consistent applications.

Yes, a surfactant can be used with 4-Speed XT Selective Herbicide however the product label advises the following: "Adding oil, wetting agent, or other surfactant to the spray may be used to increase the effectiveness on weeds, but doing so may reduce the selectivity to turf resulting in turf damage.
It is recommended to do a small compatibility test in a glass jar prior to the application. Review the full product label for more information and Compatibility Instructions on page 5.
Yes, a surfactant can be added to 4-Speed XT Selective Herbicide to increase effectiveness on weeds but is not required. The label does state that if one is added some turf damage may occur due to reduced selectivity.
