The only reason it doesn't kill zoysia dead is that it's dormant at the
time.

Similar issues with application at times is hot and dry and stuff isn't
actively growing.

Like most other herbicides, against well-established wood brush it will
undoubtedly take multiple applications or combinations to kill all the
roots so it won't re-establish.




I have not used Roundup for a while, but have used other brands that
have the same Glyphosate in them. They cost less for the same
concentration and have other chemicals in them. Mainly something to
help make it stick to the leaves. That is the only place on the plants
that the glyphosate is absorbed. Poision ivy is slick and most sprays
will just slide off. It usually gets rid of the poison ivy without any
trouble if sprayed on during the growing cycle.

Same here. I have a 2.5 gal jug of 45% Razor, lasts many years.
I suppose the price of all that will be going up with the ambulance
chasing lawyers rounding up people to sue. So far they've just gone
after Monsanto, the big fish. Funny thing, in all the years of using
it around here, I rarely get any on me at all, let alone winding up
drenched in it like the janitor claims happened to him.
