It can also be used to kill downy mildew by high temperature and high humidity. The specific method is: in the case of large air humidity in the shed after irrigation, the greenhouse is closed at noon on sunny days, so that the temperature inside the shed is as high as 35 Â° C or more, and after 2 hours of suffocating shed, the air is gradually ventilated to cool down.
