gledhillda, the Rounup product I have is Roundup Pro Biactive. There are several applications for various situations. I do not know the product ultra 3000.
If what you have is Agricultural Roundup I think the rate is 25ml in 1litre of water for a knapsack sprayer.
Might I suggest you check where you bought the product and write the dilution rate on the container with a chinagraph pen.
