最近,澳大利亚新南威尔土州的昆虫学家摩瑞宣布了一项叫做Siroflo的防治粮食虫害的新技术,这项简单的熏蒸技术可较常规法更有效地去掉谷物仓库中的害虫。它是用抽风机吹入浓度低而稳定的磷化氢与氯气或二氧化碳混合气体到仓库中,使熏蒸剂弥漫于谷物堆中,而且气体浓度很低,仅为0.02毫克/升,但如果仓库内温度下降到低于15℃时,可将浓度提高到0.05毫克/升,因为在低温下昆虫的耐药力增加。每次熏蒸有效时间不少于21 More recently, entomologist Murray of New South Wales State of Australia announced a new technology called pest prevention and control called Siroflo, a simple fumigation technology that removes pests in cereal farms more effectively than conventional methods. It is the use of suction blower blows a low concentration of stable phosphine and chlorine or carbon dioxide gas mixture to the warehouse, so that the fumigant diffuse in the grain heap, and the gas concentration is very low, only 0.02 mg / l, but if the warehouse When the internal temperature drops below 15 ° C, the concentration can be increased to 0.05 mg / liter as the insect resistance increases at low temperatures. Each fumigation effective time of not less than 21
