For the last long while it doesn't seem to matter what herbicide I use whether it be Roundup or Killex it just doesn't kill the weeds that are sprayed. They sicken but don't die. I am carefull to make sure that the mixture is correct and I have tried dish soap as a surfactant but no luck. I have tried making it stronger. I have purchased new stuff thinking that maybe the product has a shelf life. Nothing works. It hasn't always been this way. Years ago if you sprayed a weed it died completely. So this is a bit perplexing. Any ideas as to what's going on?

The weeds are becoming resistant. Spray them two or three times. Plants with waxy coatings can't be killed with roundup.
