The prevention and control of seedling blight is mainly through bed soil acidification, creating an environment that is not conducive to the growth of pathogens, to achieve the purpose of prevention and control. Chemical control also has a good effect, such as clearing the seedlings with a disease or standing and boring a closed seedbed or a 1-leaf spray. In addition, attention should be paid to ventilation and hardening of seedlings to prevent and cure seedling blight, especially one of the keys to physiological blight.
