Asked March 24, 2026, 11:05 AM EDT

Do you know anyone or any service that can treat my lawn with carfentrazone (speed zone)? I need whole lawn treatment, not just spot treatment.

Hello
MSU Extension does not recommend brands or retailers, so we do not maintain lists of service providers. 
We can give you information about Landscape associations that have search tools to find services.

Here are some resources you can search for landscape services:

Michigan Green Industry Assoc.

The MNLA website-
