Chuledrum virus disease commonly occurs in China. The disease causes poor plant growth, and bulbs and flowers become smaller year by year.
Symptoms: Symptoms of the diseased plant produce chlorotic lumps or lesions on the leaves. When the disease occurs seriously, the lesions or mosaics develop brown necrotic spots. Sometimes broken brocades form on red flowers.
Pathogens: Cucumber mosaic virus and Hippeastrum virus.
Incidence pattern: Cucumber Mosaic Virus spreads through friction and aphids, and Hippeastrum Mosaic Virus spreads through sap. In the process of conservation management, tools and hands are also important ways of transmitting viruses.
Prevention:
1 Strengthen cultivation and management: Choose healthy bulbs as breeding materials. Pay attention to the disinfection of hands and tools during operation.
2 chemical control locusts.
