What is Maneb?

Plain description, key identifiers and synonyms

Maneb is a yellow powder or crystalline solid. It is denser than water. Contact may irritate skin, eyes and mucous membranes. It may be toxic by ingestion. Likely to generate heat spontaneously upon exposure to air or water. May be sufficient to ignite the material. Maneb is used as a fungicide. Formulations of Maneb include mixing it with many other chemicals such as sulfur, zinc oxide and others to desensitize it. This is done to make it easer for application.
