Directions for use

It is a violation of Federal law to use this product in a manner inconsistent with its labeling. For any requirements specific to your State or Tribe, consult the state or tribal agency responsible for pesticide regulation. Do not apply this product in a way that will contact workers or other persons, either directly or through drift. Only protected handlers may be in the area during application.

AGRICULTURAL USE REQUIREMENTS

Use this product only in accordance with its labeling and with the Worker Protection Standard, 40 CFR Part 170. This standard contains requirements for the protection of agricultural workers on farms, forests, nurseries and greenhouses, and handlers of agricultural pesticides. It contains requirements for training, decontamination, notification and emergency assistance. It also contains specific instructions and exceptions pertaining to the statements on this label about Personal Protective Equipment (PPE), notification to workers, and Restricted-Entry Interval (REI). The requirements in this box only apply to the uses of this product that are covered by the Worker Protection Standard.

For enclosed environments: There is a restricted entry of one (1) hour for this product when applied via fogging or spraying to growing plants, surfaces, equipment, structures and non-porous surfaces in enclosed environments such as glasshouses and greenhouses. PPE requirement for early entry to treated areas that is permitted under the Worker Protection Standard and that involves contact with anything that has been treated, such as plants, soil or water, is coveralls worn over long-sleeved shirt and pants, waterproof gloves and shoes plus socks.

There is a restricted entry of zero (0) hours for pre-plant dip, seed treatment, soil drench, mop, sponge, dip, soak, rinse or other non-spraying or non-fogging application methods when used in enclosed environments such as glasshouses and greenhouses.

For field applications: Keep unprotected persons out of treated areas until sprays have dried or dusts have settled.

Non-Agricultural Use Requirements

The requirements in this box apply to uses of this product that are not within the scope of the Worker Protection Standard for agricultural pesticides (40 CFR Part 170). The WPS applies when this product is used to produce agricultural plants on farms, forests, nurseries or greenhouses. Keep unprotected persons out of treated areas until sprays have dried or dusts have settled.

Mode of Action

Sodium carbonate peroxyhydrate, the active ingredient in PerCarb, is a combination of sodium carbonate infused with hydrogen peroxide (H2O2). The active ingredient, upon activating with water, releases H2O2 which oxidizes pathogen cell structures upon contact resulting in significant surface and intracellular damage resulting in cell death of pathogens. The residual Sodium Carbonate plays a preventative role by inhibiting the development of fungal mycelium and spores through changes in pH and osmotic pressure of the target pathogen cells.

Foliar Spray Program
  • USE FOLIAR SPRAY APPLICATIONS THROUGHOUT THE GROWING SEASON ON LABELED CROPS. PREPARE SOLUTION BY MIXING 0.25–0.75 LBS. (4–12 OZ.) OF PERCARB/25 GALLONS OF WATER (1–3 LBS./100 GALLONS OF WATER). USE UP TO 400 GALLONS OF SPRAY SOLUTION/ACRE.
  • FOR THE MOST EFFECTIVE RESULTS, USE ENOUGH VOLUME OF SPRAY SOLUTION TO OBTAIN COMPLETE AND UNIFORM COVERAGE OF FOLIAGE AND STEMS. REPEAT SPRAYS AT 7–10 DAY INTERVALS DURING PEAK DISEASE PRESSURE.
Dormant Spray Program
  • USE DORMANT SPRAY FOR EARLY AND LATE SEASON APPLICATIONS ON TREE NUTS, TREE FRUITS, SMALL FRUITS, BERRIES AND VINE CROPS PRIOR TO BUD OPENING. PREPARE A SOLUTION BY MIXING 0.75–1.0 LBS. OF PERCARB/25 GALLONS OF WATER (3–4 LBS./100 GALLONS OF WATER).
  • USE UP TO 400 GALLONS OF SPRAY SOLUTION/ACRE. FOR THE MOST EFFECTIVE RESULTS, USE ENOUGH VOLUME OF SPRAY SOLUTION TO OBTAIN COMPLETE AND UNIFORM COVERAGE OF FOLIAGE AND STEMS.

Personal Protective Equipment (PPE)

Handlers who may be exposed to the dilute through application or other tasks must wear: long-sleeved shirt and long pants, and shoes plus socks. Handlers who may be exposed to the concentrate through mixing, loading, application, or other tasks must wear: coveralls over long-sleeved shirt and long pants, rubber gloves, chemical resistant footwear plus socks, and protective eyewear (goggles or face shield). Follow manufacturer’s instructions for cleaning/maintaining PPE. Discard clothing and other absorbent materials that have been drenched or heavily contaminated with this product’s concentrate.

  • Remove PPE immediately after handling this product. Wash the outside of gloves before removing. As soon as possible, wash thoroughly and change into clean clothing.
Environmental Hazards

This pesticide is toxic to birds. This product is highly toxic to bees and other beneficial insects exposed to direct contact on blooming crops or weeds. Do not apply this product or allow it to drift to blooming crops or weeds while bees are actively visiting the treatment area. Do not apply this product or allow it to drift to crops where beneficials are part of an integrated pest management strategy. Do not contaminate water when disposing of equipment washwaters or rinsate. Do not use near waterbody margins during amphibian breeding seasons.

Storage & Handling

Storage and Disposal

Do not contaminate water, food, or feed by storage or disposal.

PESTICIDE STORAGE: Store in original container in a cool, well-vented area, away from direct sunlight. Do not allow product to become overheated in storage.
