Algae-fighting plants

According to Tropica Plants, Ceratophyllum Demersum exhibits
"alleopathic behaviour". That is, it excretes substances that inhibit
algae growth. Does anyone know if other plants do this? Do these
substances also inhibit general plant growth or is the effect limited
to algae?

It seems that if this is true, then algae control could at least be
given a boost by using bunches of plants that exhibit alleopathic

Any thoughts?
Kind Regards,
