In the last couple of years, I've sprayed a few gallons of glyphosate and always have the same moment of doubt when nothing seems to be happening.
Because it disrupts the plant's ability to produce amino acids, efficacy of glyphosate herbicides (ie RoundUp) depends largely on the amount of sunlight and the rate of plant growth. If you mixed and applied it properly, you generally see results in 7-10 days.

Possibly so on large, broadleaf plants in a growth cycle. Grasses and other kinds of weeds take longer.
For selective control of noxious plants, I've rigged a wick-type applicator so that I can place roundup directly on the plant's leaves..time consuming but, I con't have to worry about killing the grass around undesirable plants.
