This product kills all the weeds it says it will kill plus other broadleaf weeds as well and is safe on couch. I use it at 30ml per litre and I’m so happy with the results as well as the service from Specialist Sales.

knocked over my paspalum and crab crass investation, allowing the couch to take hold. With a few more applications should see that back end of it.

Nothing was getting rid of the paspalum from my back yard and I was getting sick of mowing it just to keep the paspalum down. One application of this significantly reduced the stuff and I am confident that continued use and following of the directions will clear it far better than any other product I have tried before.
Highly recommend.

Have repeat purchased this product because it works where others failed on not only broad leaf and flat weeds but advanced mullumbimby couch/nut grass.
Some initial discolouration of the couch lawn occurred.

Item was delivered much sooner than expected and I’ve gotten very good results getting rid of crab grass and paspalum in my Bermuda lawn. Killed almost all broadleaf weeds too and my Bermuda grass didn’t discolour at all.

This is the second time I have purchased this product and I love the versatility that comes with the use of one selective weed killer. I have been slowly winning the battle against a paspalum breakout and this product is doing everything it says it will do! From an economic perspective, the 10 litre bottle lasted me a whole year.
Thanks again specialist sales for referring me to this product last year 😀😀

Sprayed 4 months on new seeded couch lawn, slight bruising, colour back after 3 days.
