Product Overview

Companion Biological Fungicide is a biological fungicide that is 100 percent natural and safe. Formulated to prevent and control a broad range of foliar and root diseases such as blight, root rot, bottom- and stem-rot, wilt, and bacterial leaf spot. This formulation's active ingredient, Bacillus subtilis GB03, works by isolating and fighting disease pathogens through various modes of action. It protects the plant's root hairs by colonizing it and literally crowding the diseases producing microbes out. It also produces antibiotics which can disrupt the formation of pathogenic cell walls causing them to dehydrate and die. Once this is completed the plant's natural immune system is then stimulated to be stronger in order to better resist diseases, this beneficial process is called Induced Systemic Resistance (ISR). It can be used alone, in rotation with, or in combination with chemical fungicides. This formula is also compatible with most high-quality fertilizers, organic materials, micronutrients, surfactants, wetting agents, most fungicides, insecticides, and herbicides.

Tank Mixing: Special care should be taken when tank mixing.

  1. SHAKE WELL before use and before mixing with water.
  2. Remove scale, pesticide residues, and other foreign matter from the chemical supply tank and entire injector system. Flush with clean water. Failure to provide a clean tank, void of scale or residues may cause the product to lose effectiveness or strength.
  3. Companion Liquid Biological Fungicide must be diluted with water prior to use. Determine the treatment rates as indicated in the directions for use and make proper dilutions.
  4. Prepare a solution in the chemical tank by filling the tank three-fourths level with the required water and then adding the specific amount of Companion Liquid Biological Fungicide to the tank as required. Add the remaining water. Mix thoroughly. Maintain agitation while spraying.
  5. Check pH of tank mix solution prior to adding Companion Liquid Biological Fungicide. DO NOT mix into tank solution if pH is below 4 and above 9.
  6. DO NOT let stand overnight.
  7. Companion Liquid Biological Fungicide can be applied in conjunction with most fertilizers and most pesticides. Check for Compatibility with other products.

Compatibility: Companion Liquid Biological Fungicide is compatible with most high-quality fertilizers, micronutrients, organic materials, wetting agents, surfactants, most fungicides, herbicides, and insecticides.

  • Do NOT mix with copper based fungicides, concentrated acids such as sulfuric acid, solvents, oxidizing agents or bactericides.
  • Do not mix with products with a pH below 4 or above 9. Consult specific product labels for additional information or restrictions concerning tank mixing. Observe the most restrictive of the labeling limitations and precautions of all products used in mixtures.
  • Companion Liquid Biological Fungicide has been evaluated for phytotoxicity on a variety of crops under various normal growing conditions. However, testing all crop varieties, in all mixtures and combinations is not feasible. Therefore, prior to treating entire crop, test a small portion of the crop for sensitivity.
