All the bindis killed (which is what motivated me to get it) and most other weeds as well. Unfortunately despite claims non buffalo grass weren't be affected, it killed much of the grass as well.
Ended up with a near totally brown back yard but the lawn slowly took hold again and ended up with a less weed infested lawn -for a while. Unfortunately still couldn't walk bare foot for a long time as the physical Bindi spikes were still everywhere and they really hurt for such a tiny thing. Like stepping on glass shards.
I don't regret using the stuff as the lawn is still much better than the desperate situation before, but no miracle worker. Only use when there's little to lose.
