The weeds close to the crop are only problematical if you dont start with a=
clean seedbed and/or heavily fertilize the seedbed before planting the cro=
p, which favours the weeds. Start with a clean seedbed and postpone fertili=
zation, and ...OK
it's a treadmill. You start using herbicides and then you breed crops that =
are not competitive with weeds.. so yes those crops are very difficult to c=
ontrol mechanically although it can be done. Mechanical tillage can be very=
sophisticated. As well, we separate crops and livestock so we dont want st=
raw, so shorter cereals are OK. Separated livestock and crops results in ma=
ssive aquatic pollution-- we pay for that indirectly. Real cost accounting =
would not rate GMO crops more cost efficient today and their costs have gon=
e up as more resistance develops.=C2=A0
We have created an industrial production system that is part of our social =
fabric... it's not easy to re-evaluate.. and pursue a new tack but we need =
to start looking at it. Those gigantic fields of GMO maize, soy and cannola=
may give us "cheaper food" but we are paying for it in many other ways.

The reason Herbicides=C2=A0 are so much better from a farmers point of vi=
ew David is that herbicides kill the weeds close to the planted crop. T=
he weeds in the middle of the rows are not very harmful and are easy to c=
ontrol by cultivation. However the weeds close to the plants cause the re=
duction in yields. They rob moisture, nutrients sunlight and harbour inse=
cts but there is no way a farmer can remove them by cultivation. short of=
the old hand hoe. In addition they make harvesting more difficult by not=
allowing the crop to dry out in the short days of fall. Farmers tell m=
e herbicides give the best return on investment of all their inputs. But =
maybe we would like to pay more for food! Enjoy the thaw Paul =C2=A0 =

David, no confusion here. Listserve focus is on nature not human safet=
