Assessing CO2-Modified atmosphere fumigation in a concrete maize silo for feasibility, gas distribution, and insect control efficacy

Key Points

• CO2-modified atmosphere fumigation effectively controls insects in a maize silo environment.
• Control rates for pests reached over 80% under modified conditions, ensuring better grain preservation.
• Assessment focused on gas distribution patterns across various silo heights and volumes to understand efficacy.
• Results suggest that this method could have significant implications for pest management in stored grains.
