Last Updated: 2024/11/24, It is mainly spread by bulbs, infecting new buds in the process of tulip germination, causing disease in the aboveground part. The suitable temperature for infection was 10 ℃ ~ 15 ℃, which was consistent with the growth temperature of tulip in the early stage. The disease occurs more frequently during the period from bulb germination to the expansion of the first leaf, which can last until flowering. At the initial stage of the disease, the disease spot on the leaf was waterlogged or gray-white disease spot, and in severe cases, the epidermis was detached from the mesophyll, resulting in cracking to expose the mesophyll, and yellow disease spots were formed on the bulb. Control methods: diseased plants are removed and destroyed in time, and agricultural streptomycin is sprinkled in the surrounding soil.
