Yates Buffalo Pro Hose-on Weedkiller

I have a 3/4 Acre block with a mixutre of different grass families gowing in it. The target area had clover growing though the buffalo lawn. I sprayed the mixutre 5 days ago exactly following the instructions, and as of today the only thing dying in the areas of application is the beautiful buffalo grass! All turning yellow and starting to fade away. The clover is shining through now and i am faced with the possibility of digging the entire area up and starting again, 500m2 + mind you not exactly a cheap exercise.
I had a number of people tell me not to use it but chose to believe the product advertisement instead. Lesson well learned.

The container I bought leaked profusely. The cap on the front that is supposed to stop the mixture until you are ready just blew open. Everytime. (No, I didn't apply a huge amount of water pressure, even though the label indicates "moderate to high.")
Plus, it leaked significantly out the back where the hose connects. (No, my connector worked fine on other connections.)
It kills weeds, but I would not buy it again due to the difficulty of applying it.

Im trying to limit my spray just to grass areas but if a little goes on hedges or plants, will it kill them? Eg a small rosemary plant or lemon tree?

Used buffalo pro weed killer on my lawn to kill what I believe to be some sort of brassicas, directions say won’t see results for a couple of week, but can you believe it weeds dead overnight. Fantastic.

Used this on my weed-ridden lawn recently.

Very effective against pennywort, bindii and dandelion.

Clover took several applications to eradicate, but ineffective against richardia.

Also expensive and no shut off valve makes using it somewhat cumbersome.

Have sprayed my lawn with this and has already been a week and the weeds are nearly all goon.
I had lots of clover on my lawn and it looks great not to have it all on my lawn.
This is a great hose on applicator and is very easy to apply.
Hose on applicator is great

I sprayed my lawns twice with the appliccation it said on the box but very little happened, the clovers leaves went a little brown but did not kill the clover at all. Very dissapointing. But there is little that will work with buffalo but this one was not worth the time.
