What makes ZeroTol 2.0 different from other products?

ZeroTol 2.0 is the fire extinguisher for bacterial, fungal, or algal fires. ZeroTol 2.0 provides an immediate knockdown of organisms that could harm turf and ornamentals. Most algaecides and fungicides need time to affect harmful organisms; this could lead to a mutational resistance of these chemistries. Due to ZeroTol 2.0’s fast-acting oxidation process, mutational resistance is not possible.

  • How to Use ZeroTol 2.0
    ZeroTol 2.0 Application Rates
    Foliar spray 0.5–1.25 fl. oz./gallon. Use non-ionic spreader/sticker. Use lower rate more frequently on softer vegetation.
    Spray Intervals: 5–7 days
    Drench 0.5–1.25 fl. oz./gallon. Use non-ionic wetting agent.
    Spray Intervals: As needed to remove root zone infestation
    Mist propagation - continuous rate 25.6 fl. oz.–128 fl. oz./1,000 gallons
    Cutting dip 0.5 fl. oz./gallon. 45–60 seconds, air dry
    Turf 1.25–2.5 fl. oz./1,000 sq. ft. 2–3 gallon solution. Use non-ionic wetting agent to aid penetration and contact.
    Boom irrigation When using boom irrigation inject ZeroTol 2.0 as a continuous application at a rate of 1:2,500-1:5,000.
    Fogging ZeroTol 2.0 can be applied as an aerosol/fog using approved commercial cold or thermo fogging equipment. Use a rate of 5.0-16.0 fl. oz. of ZeroTol 2.0 per 10,000 sq. ft of greenhouse area mixed in 0.5-1.0 gallon of water.
    * Not approved for use in California
    Pre-plant dip Use 64 fl. oz. per 50 gallons of water, a dilution of 1:100. 2. Immerse plants or cuttings. Remove and allow to drain. Do not rinse.
    Nutrient/Reservoir tank Use at a rate of 1:2,000-1:10,000 (0.128-0.64 fl. oz per 10 gallons of water). Use lower rates (1:5,000 or less) for seedlings and/or plants with sensitive root systems. Recharge as needed when fresh water is added, or at least once every 5-7 days.

    * Compatibility at 1.0% v/v (1:100) strength ZeroTol 2.0 solution. It’s recommended to add ZeroTol 2.0 first to full volume of water in tank, mix and then add the tank mix partner.

    • ZeroTol 2.0 solution is tank mix compatible with listed solution. Due to varied sensitivity of plants to chemicals under given set of growing conditions and plant varieties, it’s recommended to conduct an additional phytotoxicity evaluation on small set of plants to ensure tank mix solution is safe before using on large scale.

    • ZeroTol 2.0 solution is either not tank mix compatible or tank mix partner is not specifically tested for compatibility. Standard jar test and phytotoxicity evaluations need to be conducted before considering for tank mixing.
