Active Ingredient Name: Polyoxin D Zinc Salt
OPP Chemical Code: 230000; (CAS# 146659-78-1)
Polyoxins are a family of chemicals produced by a specific bacterium naturally found in soil. The bacteria are grown commercially, and the polyoxins are then purified in the form of Polyoxin D Zinc Salt. This active ingredient inhibits the action of an enzyme needed by the target fungi for making chitin, a component of the cell wall. Without chitin, susceptible fungi are unable to continue growing and infecting plant cells.
Based on required toxicity tests, no risks to humans are expected when products containing this active ingredient are used according to label directions.
There was no toxicity to land mammals, insects, or birds in various tests. The product label reflects the concern for possible harm to freshwater invertebrates and fish by prohibiting the use or disposal of Polyoxin D Zinc Salt in bodies of water.
