## Why we chose it

The active formula is a tri-salt polymer: as the spray dries, sodium carbonate, sodium bicarbonate, and trisodium phosphate crystallize and physically crush mold cells at the root, then form a barrier against regrowth. No bleach, no ammonia, no VOCs, no fragrance. EPA Category IV registration, the safest toxicity tier for a registered pesticide.
