Control method: When this disease appears, it must be controlled at the early stage. If it is delayed too long, it will be very difficult to cure completely. To deal with this disease, we can use a 150 to 200-times high-fat film emulsion to spray the diseased plants, generally once every 7-12 days. After 1-2 applications, it can basically recover.

3. Gray mold disease

Symptoms: Gray mold is a disease caused by fungi and is relatively common in fig pest and disease control. It mainly harms fig fruits. When it occurs, a grayish-white mold layer appears on the skin of the fruit. As time goes on, the mold layer gradually spreads to the whole plant, eventually causing figs to rot.

Control method: To deal with this disease, we can use 50% iprodione or 20% pyrimethanil mixed with water to spray the diseased plants, generally once every 10-15 days. After 2-3 applications, this disease can basically be eliminated.
