What gas is released by Phostoxin tablets or pellets when they are exposed to moisture?

• A. Phosphine
• B. Carbon dioxide
• C. Chlorine
• D. Nitrogen

Answer: (A)

Phostoxin tablets or pellets release phosphine gas when they come into contact with moisture. Phosphine is a potent fumigant widely used in pest control because of its effectiveness against a variety of stored product pests. When water activates the chemical reaction in the tablets, phosphine gas is produced, creating a toxic environment for unsuspecting insects while remaining safe for most other surrounding materials when used correctly. This reaction is fundamental to fumigation practices since phosphine acts quickly and efficiently, making it a preferred choice for many pest control professionals. The characteristics of phosphine, along with its relatively low danger to non-target organisms when applied properly, make it a valuable tool in the fumigation process. Other gases listed, such as carbon dioxide, chlorine, and nitrogen, do not form from the chemical reactions of Phostoxin and are not used in this context.
