Wolfberry black fruit disease damages the green fruit, flowers and buds of wolfberry, and also damages young shoots and leaves. From the early fruiting stage in early May to the late fruiting stage in mid-October, wolfberry can be infected by this disease. From May to June, when the daily average temperature is above 17°C, the relative humidity is around 60%, and there are 2~3 rainy days per ten-day period, the disease can occur in the field. From July to September, when the daily average temperature is 17.8°C~28.5°C, the ten-day rainfall lasts more than 4 days, and the average humidity for two consecutive ten-day periods is above 80%, the disease incidence will surge.
