I was going to throw in one last quick plot this weekend in a small area. I sprayed the existing weeds with Round Up Extended Control simply because it was what was on hand out at the farm. I'm a little leery on this stuff however now thinking that I won't be able to get anything to grow for 4 months. Has anybody ever used this stuff before and had any results good or bad? For the most part what I have been reading into it is that i'm basically screwed and it doesn't allow seeds to germinate for 4 months but has anybody used this stuff and if I till it multiple times would I be able to still put a plot in for this fall?

Tilling won't help when you are dealing with an extended control chemical, because as long as the chemical is in the root zone, the chemical can still be effective.

That's why it is important to read pesticide labels carefully before use.
