BioSafe Systems ZeroTol HC | Broad Spectrum Algaecide, Bactericide & Fungicide (Peroxyacetic Acid) | OMRI-Listed

Overview

BioSafe Systems ZeroTol HC combines peroxyacetic acid and hydrogen peroxide to deliver a broad-spectrum algaecide, bactericide, and fungicide. This OMRI-listed formulation is designed to work alongside existing pest management practices, offering a residue-free option that leaves no harsh chemicals behind when used as directed. While the product supports disease control and hygiene across growing environments, outcomes depend on correct application and integrated practices.

What makes ZeroTol HC stand out

• Broad-spectrum on-contact activity against algae, fungi, and bacteria helps reduce visible buildup and disease pressure in growing spaces.
• Copper-free, acid-based chemistry delivers an environmentally conscious approach with no toxic residue around kids, pets, or wildlife.
• Effective against waterborne pathogens such as Pythium and Fusarium in hydroponic or aquaponic systems, while also addressing surface pathogens.
• Designed to support overall plant health by protecting roots and stems in a variety of plants, including ornamentals, vegetables, fruits, and herbs.
• Multiple-use versatility for home, hobby, and small-scale hydroponic environments, providing a sustainable option for disease prevention.

Hard surfaces and foliar applications

• Hard surface applications: use on glazing, plastic, pots, flats, trays, cutting tools, benches, work areas, walkways, floors, walls, fan blades, watering systems, coolers, storage rooms, structures, and equipment to curb surface-borne growth.
• Foliar treatments: apply to flowering plants, ornamentals, houseplants, vegetables, berries, fruit plants, trees, shrubs, and lawns to help prevent and suppress diseases like downy mildew, powdery mildew, leaf blight, and anthracnose.

Hydroponics, aquaponics, and turf

• Hydroponic and aquaponic systems: control algae and biofilm in water lines and grow spaces, contributing to cleaner systems and potentially extended run times between cleanouts.
• Turf and landscape: suitable for well-established lawns to help prevent disease spread and algae growth, and to manage powdery mildew on landscape plants.
