Killing Kikuyu out of your lawn in Winter is the best time to do it.

Winter is one of the best times to kill Kikuyu in your Buffalo, Couch, or Zoysia turf. Kikuyu is still active in many parts of Australia, whilst the other grass types almost stop growing. Kikuyu can quickly overtake a lawn if not kept in check. If you have even a trace of Kikuyu, you will need to do one of the steps below for the next couple of winters, till the Kikuyu is eradicated. If the Kikuyu gets too thick in Buffalo, the only way to get rid of it is kill the whole lawn and start again, so it is worth taking the following advice.
Kikuyu can be mass sprayed out of Zoysia or Couch by professionals, with specialist chemicals, but this is not possible with Buffalo turf. If you are a commercial lawn maintenance contractor, then the best chemical to use is DSMA
to take out Kikuyu in Couch
. It will often take a few applications, over a few months. It’s not a one spray option. A new herbicide called Tribute
will also be launched soon, and at a recent seminar I heard that this used in combination with DSMA
has even better results taking out Kikuyu. They sprayed with DSMA
first, then followed up later with two applications a few weeks apart of Tribute
. I am not sure when the use for this will be on the label, but it is worth waiting for, because the correct application and combination increased the kill of Kikuyu to 98%.
, the only answer is spot killing Kikuyu with Round Up
. That means you can only get the Round Up
on the plant you want to kill, and must not get any on the lawn you want to keep. There are three ways to do this ( Note this can also be done for Couch
and Zoysia turf
Spray the spot where the Kikuyu is, knowing the patch that gets the Round Up on it will die. This will kill the Kikuyu, but also some of the good guy grass around it. The disadvantage to this is you will have large dead spots till the lawn regrows, and that can take some time in winter. Probably better to wait till early Spring to do this.
In Winter, after letting the Kikuyu grow taller for three weeks with no mowing, a better solution is to paint the Kikuyu with a paint brush
, making sure you get none on the grass underneath. The best way is to get a piece of cardboard, and put it under the Kikuyu, and paint the Kikuyu with Round Up
. The cardboard will stop the Round Up getting on any of the Buffalo lawn. You may need to do this again in 3 weeks, as some Kikuyu may be missed.
Again after letting the Kikuyu get taller than the rest of the lawn for 3 to 4 weeks, grab the runner in your hand, and inject Round Up with a needle into the runner of the Kikuyu
. Make sure you DO NOT stab or inject yourself. Inject each runner in a few spots. You may need to do this again in 3 weeks, as some Kikuyu may be missed. The advantage of this is that you absolutely get none on any of the desired lawn.
~ both injection and painting methods worked equally as well and this Buffalo lawn is now completely free of Kikuyu, and will fully recover once the warmer weather of spring arrives...
