Yes it will kill as it is an acidic cleaner.

No Patio Black Spot Remover can not be used on Slabs around ponds due to contamination issues, as it must be applied to saturate stone which will cause this to run into the pond. Pets do not need to be kept off Treated slabs once they have been rinsed and have dried.
