That's precisely wrong. Sodium chlorate will kill annual weeds in
low doses, and kill everything for a fairly long period in high ones.
It is definitely a 'soil poison'.

You could try glyphosate (well diluted), but I don't know how sensitive
they are - grass is very sensitive.

They seem to be immune :~( Best bet is to allways cut the seed spikes off
when ever seen and fork the clumps out, but the OP is in for a battle
