It is not difficult to say goodbye to red rot. Spray 1000 times diluted 70% thiophanate wettable powder before planting for prevention. If wounds are found on the tubers, dry them and apply sulfur powder for disinfection.

Physiological diseases

Seeing through physiological diseases

The diseases are mainly caused by harsh cultivation environment, such as strong sunlight exposure, insufficient light, sudden low temperature and long-term water shortage, which cause burns and browning of the stem and leaf epidermis, excessive elongation of growth points, frostbite of some tissues, and atrophy and withering of the tips.

The most fundamental measure is to improve the cultivation conditions, ensure sufficient sunlight, suitable lighting conditions, and timely watering and fertilizing.
