A Fl. Invasive weed

Asked July 5, 2020, 11:52 AM EDT

I have been fighting (with Roundup) a grassy weed that is called "nibblewill" or"torpedo grass". Any other treatments available? The "torpedo" has now begun an assault on my beds. Thankyou for any insight you may have.

Hello and thank you for your question. Please see this UF/IFAS publication:
http://edis.ifas.ufl.edu/wg209

Table 5 lists some control recommendations for torpedograss, Panicum repens.

Check the percent glyphosate recommended in the publication with the percent glyphosate in the product(s) you buy. Multiple treatments are required for control. Wait 2 to 3 weeks after application for regrowth and re-apply. A minimum of 3 applications will be required to control torpedograss. Do not apply to desirable plants.
