What is one of the main fumigants commonly combined with others to form a liquid grain fumigant?

• A. Carbon tetrachloride
• B. Methyl bromide
• C. Chloropicrin
• D. Hydrogen cyanide

Answer: (A)

The main fumigant commonly combined with others to form a liquid grain fumigant is carbon tetrachloride. This compound has historically been used in fumigation due to its effectiveness in controlling pests and pathogens during the storage of grains. When combined with other chemicals, carbon tetrachloride enhances the overall efficiency of the fumigant mixture, improving its ability to penetrate and treat grain effectively. Carbon tetrachloride's properties allow for good distribution and retention, making it particularly suitable in liquid formulations for grain storage environments. Its volatility ensures that it can form a gas that can penetrate deep into grains, providing comprehensive pest control. Other options, while being fumigants, are less commonly used in liquid grain fumigants. Methyl bromide is effective but has been phased out in many areas due to environmental concerns. Chloropicrin is often used as a warning agent in other fumigant formulations rather than in grain fumigants. Hydrogen cyanide is a potent fumigant but is primarily used for disinfection and in specialized settings, not typically for grain storage.
