If the Aquacap does not contain the yellow color agent as in the 3-EC and other Pendulum herbicide, then why did it stain the rock? I rinsed the gravel bed twice and it only lightened the yellow tint.
The Pendulum AquaCap reduces staining potential but there is still the potential for Pendulum AquaCap to stain porous surfaces such as stone and wood. The Pendulum AquaCap label states that you should avoid unintentional contact of spray solution to driveways, stone, wood, and other porous surfaces and recommends that you rinse surfaces IMMEDIATELY using a heavy spray of water to avoid staining.
