Roundup Zero effectiveness on Kikuyu grass lawn
YMC
I have one section of my garden which is covered with Kikuyu grass. I want
to kill all that grass using roundup and zero. How long must I use it before
I erradicate it 100% completely?

That is a bit of how long is a piece of string question.
Spray it at 1% when on a warm day and give it a fortnight(?), repeat as
neccessary. Shortened if you are prepared to pull up runners

Has anyone else found that with Roundup?

Are you using the concentrate or the pre-mix?

I have the herbicide in the concentrate form. I'm using the dosage as 20ml
per 1 litre of water.
I'm pretty fed up of the kikuyu. It got into that section of the garden
about 8 years ago. We seldom go there and now its rampant.

Sounds like the pre-mix to me.
If you buy glyphosate that is 360g/litre than it shouldn't make any
difference whatever the brand name is because it's all about the
concentration of glyphosate, not the brand.
David Hare-Scott
Yup. Glyphosate is now out of patent (copywrite, whatever) so buying the
original "roundup" is not necessarily cost effective. Unless you want the
wetting agent, or the eleven secret herbs and spices.

Impossible to say, so many variables involved, but the Kikuyu is bound to
bounce back here and there over time.
If the roundup is properly applied and at a good dose, I'd say it should
be looking rather dead within 3 weeks time.
If the Kikuyu hasn't had much water lately, I'd water it the day before
you plan to spray it, the plants don't seem to take up the glysophate
(sp?) as efficiently during prolonged bouts of dry weather in my
experience.
I've been able to reduce the recommended dose by a third if the previous
day was wet, and the following day is drizzly and overcast, or has very
light rain. Perfect conditions to apply roundup...

I lived on a dairy farm as a kid where kikuyu was very welcome in the
paddocks, but not so welcome in the vegetable garden. We didn't have roundup
or zero, we had consistency which is all that is needed.
I would advise one dose of roundup to kill off the present crop and then 10
minutes of your time every second day. You can get rid of any weed that way.
A better idea, if your council will allow it, is to run wire netting around
your problem area and put in a few hens. They'll destroy your kikuya and pay
you with eggs. When all the kikuya is gone, if the kids haven't become over
fond of them, you can then eat the hens. Very cost effective.

I'm surprised. I really am. Well, that's great cos I appiled the roundup
20ml per litre - and the next day we had some very slight rain and it was
generally overcast.

Didn't look - just got it from Kmart on their shelves. Will have a look and
report back. Thanks

Conclusions and
recommendations
It is clear that all of these herbicides have some effectiveness in
controlling
kikuyu without affecting L. oleraceum . Particularly good control is
provided
by Targa Centurion with Conqueror crop oil, Gallant with Uptake
and Fusilade with Conqueror crop oil. Because Gallant was the only
herbicide tested with label directions for treatment of kikuyu it is
recommended that this be used with Uptake at the following rates to control
kikuyu.
Knapsack, 60 mL/10 Lwith 100 mL/L Uptake
Gallant concentrations;
Water rate of 500 L/ha

However, I have had success with baking soda and boiling water then
dig up the runners and just keep hitting hard
Also it does not like SALT But that may bring other issues later on for
your lawn unless you have access to heaps of gypsum

Eric you are correct to get rid of the stuff it takes LOTS of hard
work as well as the chemical treatment .
It is mongrel stuff if you do not want it otherwise the man better get
a wooly lawn mower on a tether :)

Thanks Erik.
Well, the plan is to plant a small tree where the kikuyu is growing. I plan
to spray it with concentrate roundup 20ml+1litre in the following month.
Application once a week. And follow it up with repeated sprays as and when
they do appear.
Its not my tree - and frankly I don't really care for it - I'm only planting
it there because someone (who has minus zero ideas about gardening ) gave me
orders to do so.
But anyways I realize that the kikuyu is an inappropriate grass to be
growing in that area of the garden. Its hard to get the mower there.
Thanks

Indeed it does . Good luck with that grass

That gets rid of it better than anything, as someone already suggested.
As far as using herbicides, that really silly if its not needed....news:495df46a$0$19326$afc3...@news.optusnet.com.au...

Interesting. I agree with you about the fact that the plants need to
be active for the best results. But I must admit that I feel that rain
within 24 hours after application is not so good, I have always
assumed that the rain washed the roundup away.
No real scientific basis for this it is just that on the rare occasion
that the roundup has not been very effective there has usually been
rain shortly after application.
One thing I have found is that using roundup at more than the
recommended dosage (10cc per litre?) is a waste of the product though
I haven't tried using lesser doses.
Wonderful stuff ;)

It should have been absorbed by then.

From what I've been told by other people, you do not need much on Kikuyu,
aka making it stronger has no noticeable effect.

They give em a peck to see if theyre still alive, if not they continue to
