Which of the following is one of the common fumigants used for bulk grain?

• A. Chlorine
• B. Phospine
• C. Hydrogen peroxide
• D. Carbon dioxide

Answer: (B)

Phosphine is a widely recognized fumigant specifically used for bulk grain storage. It is known for its effectiveness against a range of pests that can infest grain, such as insects and other microorganisms. Phosphine works by releasing gas that disrupts cellular functions within the pests, thereby eliminating them effectively. Its application is particularly valued in grain storage due to its ability to penetrate deeply into the grain mass, ensuring thorough treatment even in larger quantities. In contrast, the other options mentioned do not serve the same purpose for bulk grain fumigation. Chlorine is primarily used for disinfection rather than fumigation and is not suitable for treating grain. Hydrogen peroxide, while having some pest control properties, is more commonly used in surface sanitation rather than as a fumigant for bulk stores. Carbon dioxide can be used in certain pest control situations, but it does not have the same level of efficacy as phosphine for bulk grain pests. Therefore, phosphine stands out as the correct choice for this fumigation practice.
