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

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
