4-Speed XT provides rapid, effective control of a wide range of post-emergent broadleaf weeds in many settings, including cemeteries, athletic fields, golf courses (aprons, fairways, roughs, and tees), parks, lawns, sod farms, and other professional turf sites. The high-powered blend of four active ingredients creates a combination that is deadly to almost any broadleaf weed, including tough weeds like ground ivy, violet, and spurge. Results will noticed in as little as 24 hours.
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.
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.
looks like it is working on my Wild Violet problem - as well as all other weeds
in 24 hrs - wilting . dandelions as well curling up- in 1 week 50 % gone but I will take couple of weeks I guess -
Went this this version - Weed B Gone did not work - as well as Oxylic Weed killer
How long before you can water after an application of 4-Speed XT?
What is the safe time before pets can use the yard?
Do not apply 4-Speed XT if rainfall is expected within 4 hours and avoid irrigation for 24 hours following the application. Children and pets should not be present during the application and may return after the treated surfaces are completely dried.
When 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.
