Luckily you shouldn't need the chemicals you mention above to best gain control of the invasive Japanese stiltgrass.

Understanding a weed's lifecycle is needed to know the best (and least toxic) way to handle them. Japanese stiltgrass is a summer annual, which means it dies with frost each year. Seeds germinate in spring and start new plants every year.

Like crabgrass, the best way to control is to prevent germination, so in this case you would apply a pre-emergent pesticide, like those used for crabgrass control, with application a couple weeks earlier. (For lawns).

This weed has shallow roots and is easy to pull, which is what we recommend for garden beds. A layer of mulch can help keep weeds from germinating.
