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.
Here is our page on Japanese stiltgrass:

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.
