Weed Impede and sandspurs
Will Weed Impede stop Florida SandSpurs from growing?
The active ingredient Oryzalin in Monterey Weed Impede is known to be used as a pre-emergent for Sandburs. Your best control begins in mid-February with a pre-emergence herbicide application. Follow the label, and treat again as needed.
