Hi,

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?

Cheers

Have been watching this thread as down south the stuff is a HUGE pest and
has taken over the wetlands no end

From an old trial paper in NZ
Quote
"
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
(NZ agrichemical manual 1998/99)

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

I didn't reply earlier because I was unsure what the original poster wanted
to do with the garden. Kikuyu is very hardy, withstands drought and many
weed killers etc.

I didn't snip either so probably nobody will get to see this. ;-)

If the intention was to poison the Kikuyu this week and make new plantings
in the same area next week, I wouldn't think it would be too successful.

One of the Pathweeder type products would be the best to get rid of Kikuyu.
The problem there is that they say they sterilize the soil for up to 12
Months (perhaps that is bit of wishful thinking) but if new plantings are
made soon after using a Pathweeder product the new plantings won't prosper.
If you have a substantial Kikuyu growth it can't be eradicated by hand, use
of a specific weed killer is necessary.



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
