Ok, I stirred myself to do an a2k search re monsanto, looking for what I remember about later resistant weeds, re round up. Bingo, this is the thread I remember and right away MsOlga gives a link that includes mention of superweeds/some study (that doesn't work now, old link), then a quick comment by green witch (someone I miss badly), and then the post by farmerman that I was remembering....

haven't read the rest of the thread yet..
as I said, I also read some other article re the superweed problem; I checked, and while I likely saved it, it must have been before my last exciting computer meltdown.
I've also used round up in my various yards once in a while, but mostly have hand weeded (or shoveled and grabbed) for years, even decades.. I used to like to weed, quiet time, and progress happened.
I do remember specifying round up (the grow and kill application, that uses it three times) to clear the dreaded algerian ivy.
Now I'm gonna try Edgarblythe's recipe that involves original dawn soap and vinegar, back with a link or at least the recipe. I need something since I'm now way less apt to run out my front door just after dawn (hot days here) to start weeding, much less at twilight, never in the mood then, baaaaad.
I remember something called pre-emergent, which I probably only used once, ever, years ago. I've no idea how much an environmental problem that has turned out to be, but am pretty doubtful it's a great thing. It keeps weed seeds from emerging.
On the superweeds, I've not read up yet. Are they still considered a problem?
