Abstract

The invention relates to the technical field of plant prevention and control methods, in particular to a method for preventing and controlling diseases of grapefruits. The method comprises the following specific steps: (1) treatment of virus-free seedlings: treating cuttage strips by using purpose-made ointment; (2) cultivation of the virus-free seedlings: cultivating cuttage seedlings by using nutritional soil; and (3) treatment in a fruiting period: when the virus-free seedlings cultivated by the cuttage seedlings enter a fruiting period, sterilizing a garden area once every 3-5 days, and meanwhile ensuring ventilation of the garden area. From experiments, by the method for preventing and controlling diseases of the grapefruits, the incidence rate of various diseases of grapefruit treescan be reduced effectively, and compared with a traditional method for preventing and controlling the disease of the grapefruits, the method for preventing and controlling the diseases of the grapefruits has the advantages that the incidence rate of the diseases of the grapefruit trees is greatly reduced, and the effect is remarkable.

Description

technical field [0001] The invention relates to the technical field of plant control methods, in particular to a method for preventing and controlling pomelo diseases. Background technique [0002] Pomelo is a citrus tree of the Rutaceae family, which is cultivated in Southeast Asian countries. Pomelo is cultivated all over the south of the Yangtze River in China, and the northernmost is limited to Xinyang and Nanyang in Henan Province. Grapefruit pulp contains high vitamin C, which has the effect of digestion and detoxification. [0003] The main diseases of grapefruit are Huanglongbing, canker, scab, anthracnose, etc. These diseases will seriously affect the growth and yield of grapefruit, and reduce the appearance and internal quality of the fruit. The prevention and control methods of grapefruit diseases are usually based on prevention, comprehensive management, strict quarantine system, establishment of disease-free mother gardens, ear picking gardens and nursery base...
