Zerotol 2.0, manufactured by BioSafe Systems, is a 3-in-1 fungicide, algaecide, and bactericide that provides foliar and root disease control on professional turfs and landscapes.

Formulated with a stable and strong peroxyacetic acid chemistry, which provides a faster surface cleaning against bacteria from the propagation to production phase of plants.

Zerotol 2.0 contains a fast disease eliminating process against a broad-spectrum of pathogens, algae, and disease like crown rot within 5 days.

Tools Needed

To use Zerotol 2.0, you will need a hose-end sprayer or handheld pump sprayer. It may also be applied through a sprinkler (center pivot, lateral move, end tow, side (wheel) roll, traveler, solid set or hand move) or drip-type irrigation systems. To apply as an aerosol/fog you will need an approved commercial cold or thermo fogging equipment.

How to Use

  • Step 1: Determine how much Zerotol 2.0 to use by measuring the square footage of the treatment area. To do this, measure the length and width of the treatment area in feet then multiply them together (length X width = square footage). For acreage, take the square footage and divide it by one acre (square footage / 43,560 sq. ft. = acres). To treat listed fruiting vegetables diseases, use a 1:100 dilution. To prevent diseases on listed fruiting vegetables, use 1:200 to 1:400 dilution. To clean hard, non-porous surfaces like benches and work areas apply 1:50 or 2 1/2 fl. oz. of product per gallon of water. For more specific application rates and restrictions refer to the product label.
  • Step 2: To mix in drip-irrigation system, use a separate container. If using a handheld pump sprayer then use the following step in the tank and not a separate container. Fill the container or spray tank with half the amount of water, add measured amount of Zerotol 2.0, then pour the remaining half of water in. Agitate the container or spray tank until the mixture is dissolved. Fill your drip-irrigation system according to its product label.
  • Step 3: When using sprayer equipment, spray the top and bottom of plants until wet, but not to the point of runoff. When using this product to clean non-porous surfaces then spray until the point of runoff.

Where to Use

Apply Zerotol 2.0 on indoor, greenhouse, and outdoor-grown: ornamental plants, flowering plants, bedding plants, nursery stock, landscape plants, turf, and all agricultural crops including food crops.

When to Use

Use Zerotol 2.0 up to and including the day of harvest for listed crops to prevent and cure diseases. Spray plants early in the morning or evening to allow enough time for the product to dry. This product may be applied when present algae is found on non-porous surfaces and when you wish to prevent listed pathogens and diseases from them.

Safety Information

Zerotol 2.0 is safe to use around children and pets when applied according to the product label instructions. Always wear the proper personal protective equipment (PPE) when mixing and applying this product.

Keep people and pets out of the treated area until sprays have dried.

Special Considerations
