VERFAHREN ZUR VERHINDERUNG DES KOMPAKTWERDENS VON AGRARCHEMISCHEM WIRKSTOFF

An agricultural chemical active ingredient which is solid at room temperature, may cake into a large lump during storage or transportation after the production, and if it is pulverized after the production or stored for a longer period of time, it is more likely to cake. If such an agricultural chemical active ingredient is put in a drum container, it will cake and will be difficult to take out from the container. Accordingly, it may be packaged in small portions and put in a container, or after being taken out from the container, the lump is crushed by a hammer. Thus, before it is mixed with various agricultural adjuvants and subjected to a pulverization step, its handing is troublesome. By adding a small amount of an inorganic substance composed mainly of silica to a powder of an agricultural chemical active ingredient which is solid at room temperature, caking of the agricultural chemical active ingredient can be prevented, and handling such as formulation, transportation or storage, of the agricultural chemical, can be facilitated.
