    Carbon Dioxide (CO2)

    Introduction Carbon dioxide is an alternative insect pest control option to the most commonly used fumigant, phosphine. Driven largely by market request for ‘organic grain’ or ‘clean & green’, carbon dioxide is usually easier to manage in smaller, gas-tight silos less than 300 tonnes. If using carbon dioxide, it should be referred to as a […]
