Will Hi-Yield Killzall Aquatic Herbicide kill water lilies and iris on the bottom of the pond?

Does it have to be sprayed? We have no leaves so we need a product that we can add to water.


Hi-Yield Killzall Aquatic Herbicide does not control weeds that are submerged or the majority of any foliage under water. We do offer other aquatic herbicides that can be applied for submersed weeds. AquaStar is labeled for treatment of mature water lily and others.
