Therefore, good seed treatment is a simple and effective method to control such diseases. However, some seed treatment methods promoted in the past such as 1% lime water soaking, cold water immersion sunburn, pharmaceutical disinfection and so have such a drawback. In the past two years, based on the principle of heat sterilization in cold-water immersion sun-drying and airless asphyxiation in lime soaked seeds,
