At the initial stage of the disease, 40% carbendazim wettable powder was sprayed twice a week for three times. Spread quicklime or lime solution to disinfect fig seedbeds and planting pits. The fig plant can be soaked in carbendazim for two hours before cutting. The medicine solution was used to soak and disinfect the base of branches and ears, and then cut it. 40% formasone was sprayed during the seedling period. After the colonized seedlings were infected, the corresponding insecticides such as methyl fumarate, copper methyl cream and Bacillus subtilis could be added to the solution of naphthalene acetic acid, and the fig plant could be irrigated once a week. The root system can be basically cured by watering the root system for several weeks.
