Title: Production of ophidiocide and soil vermin controlling agent utilizing marlstone colloid
Inventor: ISHIKAWA SHIGENOBU
IPC: A01N25/08
Filed: 1988-12-06
Abstract: PURPOSE:To obtain an ophidiocide, a soil vermin controlling agent and a soil- treating agent for preventing termite damage by dissolving a controlling agent for snake and vermin in water, immersing finely pulverized and dried marlstone in the solution, completely disintegrating the stone powder to a colloidal state and converting to a dried powder. CONSTITUTION:Marlstone is finely crushed and dried to a water-content of <=10%. separately, prescribed amounts of active components are dissolved in 1/2kg of water based on 100 pts. of the marlstone. The dried marlstone powder is completely disintegrated into a colloidal state by immersing the powder in the solution for 24hr. The objective ophidiocide, soil vermin controlling agent for agriculture, soil vermin controlling agent for lawn or soil-treating agent for preventing termite damage of building and plowed land can be produced by converting the disintegrated colloid to dried powder. Since the active component of the above agent is completely adsorbed to the mineral colloid, it is resistant to dissolution and evaporation from the soil and the drug action can be maintained over a long period. The soil vermin controllable by the agent is e.g. common cutworm and sweetpotato weevil.
