We investigated the physical control of seed-borne diseases. Blast, "Bakanae" disease and White-tip Nematode on rice. The infected seeds were immersed into 60degC hot water for 10 minutes using the hot water treatment machine. The hot water immersion showed the effect which is equal to the agricultural chemicals against these diseases. We investigated the influences of hot water treatment on germination. To avoid the decline of the germination percentage, the processing temperature is 60degC, the processing time is 10 minutes. To avoid the decline of the germination percentage, the seed which was produced at previous year must be used. Also, we kept the seeds at the constant temperature for 1 month from the treatment. The treated seeds germinated normally.
