AgriPhage™ Bactericide

AgriPhage is a bacteriophage product used for biological control of bacterial spot and speck on tomatoes and peppers. Bacteriophages are known in layman’s terms as “bacteria eaters.” They are highly desirable solutions for bacterial diseases, because of their environmentally friendly profiles and because of the resistance bacterial diseases have developed to traditional disease control products.

A bacteriophage mixture, AgriPhage is highly specific and only kills specific species of bacteria: Xanthomonas campestris pv. vesicatoria and Pseudomonas syringae pv. tomato. AgriPhage is of low risk to other “good” bacteria, beneficial micro flora or fauna. It is a viable alternative to synthetically produced chemicals that can leave behind unfavorable residues.

AgriPhage is exempt from Maximum Residue Limits (MRLs), has only a 4-hour re-entry interval (REI) for farm workers and is NOP approved for use in organic agriculture.

AgriPhage is for use against the following pests:

  • Bacterial spot (Xanthomonas campestris pv. vesicatoria)
  • Bacterial spec (Pseudomonas syringae pv. tomato)

AgriPhage can be used with the following crops:

  • Tomato
  • Peppers


Apply AgriPhage as a preventive to protect growing leaf tissue, as a curative when the first disease symptoms are visible or when conditions are conducive to heavy disease pressure. In the greenhouse, apply AgriPhage as a foliar spray or by fogging. Apply AgriPhage in the field with conventional ground spray equipment or via aerial application immediately after planting and as the plant matures.
