I bought the Bayer Three in One last year with the premixed in the bottle. I had the opposite problem. I sprayed my whole garden and still had about half of it left. So this year I bought the concentrate and mixed it myself in one of the hose end sprayer bottles. I think it was 1 tablespoon per gallon of the concentrate. I also added some liquid plant food to the sprayer. What I mixed was supposed to make 6 gallons of spray. I got about half the garden sprayed before it ran out. So I mixed it again and sprayed the rest. It was putting out quite a bit of the mix, I could see it on the leaves. I did this yesterday, they all look fine today. I have had a severe infestation of aphids this year and was tired of fighting them. I also wanted to spray for thrips, which this formula kills.
