Fully explained here -
Why weed and feed isn’t your best option -
https://lawnsolutionsaustralia.com.a...20is%20Dicamba.
"The active constituent in Weed n Feed is Dicamba. The rate of Dicamba present in Weed n Feed bottles is very low and isn’t very effective on most broadleaf weeds (hence the very cheap price of Weed n Feed) and you will usually need 2 or 3 applications to get a result.
Dicamba cannot be used on Soft-Leaf buffalo lawns, as it will cause the lawn to die back and turn yellow. This greatly limits the products use in the domestic market as a lot of home lawns in Australia are soft leaf buffalo."
Weed n Feed adds very little nutrient value to the grass. The fertiliser component mainly contains Nitrogen and Iron, which will give the plant a short boost of green colour, but usually contains zero Phosphorus and Potassium, so it does virtually nothing for the root strength and development of the plant. Which means it is hardly a fertiliser at all."
The key thing with these types of products is the short-lived effect, which in turn means you buy more of it. Also, because these products are sold through Bunning's, they water it down so much, catering to the lowest level of intelligence to prevent a lawsuit if someone kills their cat or sets fire to the lawn.
These are what we recommend, killing the whole weed rather than just the foliage -
