One was left out.
I will not recommend this strategy but It needs to be considered. Why because it has less impact than some of the others, and of your current use of the computer you are now using and conviently overlook

to solarise you must first loosen the soil.
plastic sheeting kills all organisms 6 - 8 in deep
Over crops dont work (unlees you do so for years)
chickens dont till deep enough
weed block fabric is easily pierced

all are labour intensive

Bill talks about the appropriate use of technology. some chemicals are toxic and residul others not...depends on the "Half" life. Folks use pyrethems and Kill aphids, natural yes toxic to some animals YES. So the delemer is what has least impact for the most effectiveness.

so now to the "G" word...gylphosphate salts, You cannot get emotionally locked up to not use a good tool because it has been abused by idiots. I say "Lets ban the chain saw" we have global deforestation therefore its the chainsaw that need banning!!! Stupid !!!

Use the right tool the correct way and have "Least effect for the greatest yeild".

So use Glyphosphate and follow with Compost Tea and Accumilators, hot compost the material and your field is clear in one season, all chems are gone and can be followed by a crop

(Compost Tea and Accumilators = bio-remediation turned around as part of a strategy)

So go ahead ban you chain saw, your computor, your car, your tractor, your TV, your PVC piping, your rockdust, your eye surgery, your.....

don (one foot on the edge, and the other in the middle)

Early agricultural literature used the common
name of "Devil's Grass" to describe bermudagrass
for a reason.... it is a tenacious perennial
grassy weed that spreads and spreads.

Digging up rhizomes is too labor intensive and
it doesn't even control bermudagrass since it
comes back real easy from broken root pieces.

There are several reliable ways to control bermudagrass
through non-synthetic chemical methods.

These have been discussed on this list and
through the technical literature of ATTRA.

*Clear plastic mulch as solarization.

*Black plastic mulch to block-out light

*Geotextile weed barrier to block-out light

*Sheet mulch that combines cardboard with a
top organic mulch to block-out light; absolutely
do not let grassy edges to creep back across
the top or thru the mulch.

*A sequence of shade-producing cover crops and
tillage, in multiple sequences over one or two
growing seasons, to disrupt and shade-out and
smother-out the grass.

*Green chemistry herbicides (acetic acid, citric
acid, etc) and/or thermal weed control devices
(infra-red or steam) to knock back grass on edges
of mulch.

*Place a chicken tractor over a patch of ground
and encourage eradication of vegetation for three
months.

*Use a weed eater with rubber blades to periodically
cut rhizomes and stolons that want to creep back
into a grass-free growing area such as beds
or gardens, then follow with a wheel hoe operation
to disrupt any root pieces running thru the soil.
This is managed as a bare strip of soil about 3-4'
wide between turf and garden.

The block-out mulch methods will take about
2-3 months; the aim is to completely deplete root
reserves and/or set them back severely. Solarization
takes about 6-8 weeks. A sequence of shade-producing
cover crops and tillage can take two full growing seasons,
but can be effective on large acreages managed with
a tractor.

These methods will work if you follow the principles
and whip it good, then keep it out.

Good luck,
Steve Diver
