Glyphosate is banned here in France so gardeners landscapers had to seek an alternative. That alternative isn't systemic, it only kills on contact, it's called pelargonic acid.
As you'll be aware, glyphosate translocates itself in a systemic way so as to infiltrate all of a plant's root system - especially useful for rhizomatous and stolonerifous plants that send their underground and overground stes to infiltrate and hide amongst desired ornamentals and food crops.
I did a little Google search and discovered that polargonic acid (nonanoic) was approved by the EU in 2008 but has actually been used in France since 1863. It's being pushed now in garden centres.
One intersting fact to note; polargonic acid is an earth friendly organic herbicide.
Pelargonic acid based herbicides won't kill roots of pernicious tap-rooted plants such as dandelion but it will check growth and if potentially disturb a weed if that weed isn't able to photosynthesise.
