That looks more like a recipe for disaster than weed killer to me. Little bit of vegetative cure with the vinegar, little dose of soil sterilization with the salt and some soap for surfactant.
Inevitably you get some water contamination using anything that close to a pond. Many commercial products recommend a 25 foot clearance. And they dissipate. That salt is there for decades. I don't know if it ever breaks down, but after enough gets into your pond, maybe you can farm oysters.
Anything you choose to use, including Reward, has specific directions right on the package/bottle. I would not go that route, I'd use a glyphosate product on terrestial plants, but that is a personal choice.
You know what grows in salty soil?
