Would prefer a simple non chemical solution, but if its not likely what
chemicals to use please? Thanks for advice.


Dunno what it is. What you need is a selective weedkiller. "Pastor"
kills everything except grass. It's intended for use on pastureland.
You will have to get it from an agricultural supplier.#


BE VERY CAREFUL

SOME of those types of weedkillers do NOT break down quickly, and as we
found to our cost, the grass itself if eaten by horses and other
livestock, and passed through or the raw grass cuttings, still contain
the herbicide, which is perfectly capable of ruining all your vegetable
crops until bacterial actions breaks it down, which may take several years.

Fortunately although they didn't compensate us Dow Agrochemicals at
least came and picked up all the contaminated compost..

Not sure if your product contains it, but the noxious problem was
Aminopyrolid.

Its a fine way to knock weeds out of grass, but the weeds, the grass,
and any crap from any animal that eats either, will be contaminated
until the lignin in the cells totally degrades and releases the stuff to
break down in the air.


Unfortunatelythy only sell giant bottles. Lifetime supply unless you
can share with someone.
