Works as advertised
By Matthew in Kutztown, PA 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.

QHow much 4 speed to a gallon of water?
AWhen using herbicides such as 4 Speed XT, the amount of water is dependent on the how much water it takes to cover a 1,000 sq ft area. The best way to gauge this is by marking off a 10ft by 100ft area. Fill your pump sprayer and "mock" spray the area thoroughly. This will tell you how much water to mix the 4 Speed XT with.

QHow soon can cattle graze after applying 4 Speed XT?
A 4-Speed XT†is not labeled to be used in areas where animals graze. †If you do have a grazing plot that was treated with the product then the grass should be allowed to grow high and then be cut several times before the cattle can be turned out to graze again. †A better option to use would be something like Crossbow that is labeled for pastures and except for lactating dairy animals has no grazing restrictions.
