The inoculation method of rice blast disease to the host plant in a inoculation chamber was first discovered in Japan and the method discovered made possible to find a new anti-biotic, Blastcidin S. This principle has been widely applied, and many other fungicides have been found to use practically. The specialized apparatus composed of the usual turntables surrounded by the artifical environment helped to find a new systemic fungicide, Thiophanate, which is widely known over the world. A simple method was successfully discovered for the screening of the soil-treatment-pesticides without distruction of the physical structure of the soil. Using this method, it was clarified that the penetration of the pesticide into the soil quite varied with its formulations. At present, the emulsion form is mostly used for the control of the insect pests in a deep part of the soil. Granular formulation gave the best result for the control of insect pests in the rice paddy field. This finding resulted in discovery the new formulation, pesticide for submerged application.
