Pat,

I talked to a chemical expert last night and he told me just about the same thing. Although typically 7 days is the waiting period, he told me that 3-5 days does the trick, with 3 days being pretty reliable with good conditions. He also told me Roundup Ultra works a little faster than others...for whatever reason. I look at it like it certainly didn' t hurt, and probably helped quite a bit.
