Arber Bio Protectant

Strong and healthy plants are best able to fight off disease and this innovative product provides what they need to get and stay healthy. Arber Bio Protectant uses an active ingredient that had been developed for use in large-scale agriculture and has adapted it for use by home growers. This ingredient, an extract of the Giant Knotwood plant ( Reynoutria sachalinensis ), offers protection without harsh or toxic ingredients.

When this product is applied to a plant, the plant produces elevated levels of specific proteins and other compounds like phytoalexins, cell wall strengtheners, antioxidants, PR proteins and phenolics that serve as fungal and bacterial growth inhibitors This mode of action, called induced systemic resistance, uses Arber Bio Protectant as a catalyst for the plant to protect itself.

  • Can be applied up to and on the day of harvest.
  • Safe for beneficial insects, bees, birds, pets and people.
  • Significantly reduces the possibility of resistance.
  • Use on vegetables, fruits, berries, houseplants, tree nuts, ornamental plants, trees, shrubs, roses and other flowers, bedding plants, hemp, foliage and tropical plants.

  • Do not allow spray to drift from application site.
  • Use only with pressurized hand-held sprayers or spray trigger bottles.
  • Do not allow spray mixture to stand overnight or for prolonged periods.

Use 1 fluid ounce (2 Tbsp) of Arber Bio Protectant per gallon of water.
Spray plants to complete wetness, covering both top and bottom leaf surfaces to ensure complete coverage.
To assure that the plants to be treated are not sensitive to the treatment, apply a small amount of the product to a few leaves or the above ground portion of the plant and check back in 2-4 days for signs of phytotoxicity.



To protect the environment, do not allow pesticide to enter or run off into storm drains, drainage ditches, gutters or surface waters. Applying this product in calm weather when rain is not predicted for the next 24 hours will help to ensure that wind or rain does not blow or wash pesticide off the treatment area. Rinsing application equipment over the treated area will help avoid runoff to water bodies or drainage systems.
