目前人们又研究试验了一种新的施用防护剂的方法,即随着粮仓通风扇或烘干、储藏两用仓的通风干燥系统所产生的气流将杀虫剂生成汽溶胶(湿剂)送入或吸入粮堆,这种处理方法的优点是无需翻动粮食,而且处理不受时间限制。美国农业部萨瓦纳农产品贮藏害虫研究所昆芝先生的考察研究表明,这种汽溶胶处理可将致死剂量的马拉硫磷分布到通风的脱粒玉米堆3.05米深处。昆芝先生(1979年)也表明了,如果配合使用垂直通风管,可用马拉硫磷汽溶胶处理玉米表层部分。
At present, people have also studied and tested a new method of applying a protective agent, that is, airflow generated by a ventilation and drying system of a dual-purpose storage bin generates aerosol (aerosol) from pesticides as the granary is ventilated or dried, Into or inhaled into the piles, the advantage of this treatment is that there is no need to flip the grain, and the treatment is not time-limited. Investigations by Mr. Kunji at the U.S. Department of Agriculture’s Savannah Crop Storage and Pest Research Institute show that this aerosol treatment can distribute a lethal dose of malathion at a depth of 3.05 m to a ventilated threshing corn pile. Mr. Kunzaki (1979) also showed that malathion-treated aerosols can be used to treat maize tops when used with vertical ducts.
