It mostly occurs from early May to early August. After onset, the root and the soil contact area rot, the root bark falls off, and the plant dies within a few days. Control method: drench the roots with 1:1:100 Bordeaux mixture.

Schisandra chinensis leaf blight and its control

It mostly occurs from late May to mid-July, with the lesions appearing withered yellow. It initially starts from the leaf tip and gradually expands and spreads; in severe cases, the entire leaf withers and dies. It is severe when temperatures are high and humidity is excessive with poor ventilation. Control method: spray with 400-500 times zineb and 1500 times thiophanate-methyl; preferably before onset in late April, spraying once a week for 2-3 consecutive sprays, or Bordeaux mixture sprayed once a day.
