I plan to try and use this product to maximize the effectiveness of my weed control chemicals such as Roundup and Pramitol. How do I go about mixing this product? Do I use it as a "pre spray" or can it be combined in the tank? and what is the mixing ratio?
Surf-AC 910 Surfactant is mixed directly with an herbicide and water in the same tank together. Most RoundUp products already contain a surfactant so an additional one is not needed. Per the label for Surf-Ac when used with herbicides the rate is 1- 2 pints per 1000 gallons which breaks down to 0.16-0.32 fl oz per gallon of water.
