Dealing with local weeds #2 Yarrow (Achillea Millefolium)

Sean from Carterton District

I say #2 as I have written quite a lot about Buckthorn that is rife in Carterton, but have all but eliminated from our property. Now Yarrow. Quite a bit in our lawn and in the berms in Lincoln Road Carterton. Often seen in roadsides when in flower, see pictures below. My research shows it is encouraged overseas and has some redeeming qualities, one is the use of its foliage providing good results on bleeding cuts when no sticking plaster is handy. I have a Lawnboy Sprayer and plan to give my lawn a treatment and have learnt that Dicamba that is in Turfix could have a good result. Hard to remove manually as its rhizomes (heavy stems that grows underground) are hard to remove completely. It was introduced as a component for pastures in New Zealand owing to its high mineral content and drought resistant properties but of course unwanted in our lawns! If anyone has other information to add that could be helpful, let me know.
