Citrus oil spot is a kind of physiological disease. At present, there is no specific pharmaceutical agent that can control it, but can only be carefully controlled in production and harvest. The main methods are:
1 Try to avoid fruit picking when it rains and the morning dew is dry or immediately after a strong wind. Harvest fruit after 2~3 sunny days after the rain.
2 As far as possible during harvesting, selection, packing, transportation and storage, it should be done lightly, lightly, and lightly to avoid damage to the skin.
3 The fruit harvesting is completed before frost, or the spraying of new high fat film on the canopy fruit 20 days before harvest can greatly reduce the incidence of disease.
