Evaluation of chlorine dioxide gas for managing stored-product insects

The development of resistance to phosphine in the last 10-15 years in selected stored grain insects threatens the global grain industries. It is important to investigate alternative technologies to retain phophine’s effectiveness. The efficacy of chlorine dioxide gas has been documented as alternative methods for controlling insects, molds, and mycotoxins. For chlorine dioxide, systems are available to treat structures, and manufacturing facilities for controlling microorganisms. However, chlorine dioxide has not been extensively tested to control insects on postharvest products. This study is to evaluate the efficacy of chlorine dioxide gas in controlling phosphine-resistant insects in stored grain products.
