What combination of traits influences fumigant performance in grain storage bins?

• A. Climate and pest type
• B. Grain size and pressure
• C. Temperature and humidity
• D. Light and airflow

Answer: (C)

The effectiveness of fumigants in grain storage bins is significantly influenced by temperature and humidity. Fumigants operate best within specific temperature ranges, as higher temperatures generally enhance their volatility and the diffusion rate into the grain mass. Similarly, humidity plays a crucial role; higher moisture levels in the environment can affect the efficacy of fumigants, altering their absorption and distribution within the grain. The combination of elevated temperature and humidity can facilitate the penetration of the fumigant, allowing it to reach pests more effectively and increasing the likelihood of successful pest control. This understanding is vital for determining the appropriate conditions for fumigation to achieve optimal pest management in stored grains.
