专利汇可以提供Method of killing insect专利检索,专利查询,专利分析的服务。并且PURPOSE: In the treatment of grains or oil cakes with aluminum phosphide, the reagent is forced circulation with the air that is controlled in the temperature and humidity, thus killing insects effeciently.
CONSTITUTION: Grains or oil cakes or the like are put into tightly sealed vessels, a prescribed amount of an aluminum phosphide preparation is charged in the vessel, then the air that is controlled in the temperature and humidity is forced circulation to kill insects in them. The temperature of the air is 15W30°C and relative humidity is over 30%. When contacting with moisture, the aluminum phosphide gradually hydrolyzes to evolve hydrogen phosphide gas, thus repellenting insects. This method can effect more uniform repulsion compared to conventional fumigation independently from the temperature and humidity of the grains or oiled cakes.
