Not what I've heard. Herbicide resistant crops so they can be sprayed
with
more herbicides.

simple thought will tell you that that must be wrong

herbicides cost money

GM seed is slightly more expensive

why would you pay more money for seed on which you have to use more
herbicide, again spending more money?


Bigger yield?

Not necessarily, just lower cost


So why have they developed herbicide resistant crops then? So they can use
"roundup*" to spray the weeds off instead of using mechanical means of
weeding which cost lots of money.

Perhaps you would explain to me the mechanical means of weeding either
OSR/Canola or Maize, especially late season?

These have always been sprayed, unless of course you are volunteering to
hand hoe your share?


Perhaps you have another explanation for their development?

Check no-till agriculture for one thing


*Roundup...a Monsanto product, like a lot of the GM crops.

Actually the chemical is generic now, produced by scores of firms all over
the world and sells for perhaps a third of what it used to
