Raw material fumigation

[Md. Osman Sheikh]

There are many chemicals used for fumigation, including methyl bromide, sulfuryl fluoride, phosphine, and hydrogen cyanide.

[Ndifreke Ekanem]

Phosphine (Aluminum or Magnesium Phosphide) ,Methyl Bromide, Hydrogen Cyanide (HCN), Sulfuryl Fluoride, Formaldehyde Gas (Paraformaldehyde or Formalin Fogging), Carbon Dioxide (CO₂)

[Amir Sohel]

Many substances are used as fumigants, including methyl bromide, chloropicrin and phosphine.

[Md. Abdul Bari]

For Grain Storage & Warehouses:

1. Aluminum Phosphide (Phostoxin, Celphos, QuickPhos) – Effective against insects and rodents, commonly used in grain storage.

2. Magnesium Phosphide – Similar to aluminum phosphide but releases phosphine gas faster.

3. Methyl Bromide (Restricted in many countries) – Powerful but highly toxic; used for quarantine treatments.

4. Sulfuryl Fluoride (Vikane, Profume) – Alternative to methyl bromide, used for food processing facilities and wood treatment

[Md.Rejuan Hossain]

Methyl bromide, chloropicrin, phosphine, and hydrogen cyanide. The best substance for fumigation depends on the type of enclosure and the situation being treated in the sector.
