There are two symptoms of tobacco mosaic disease.
1. Ordinary mosaic disease: Infested by virus infection, the young leaves first begin to develop. The color of the leaves along the veins turns yellow, and bright veins appear. Then the dark or light-colored part gradually expands to form a yellow-green mottled (flower mosaic); in severe cases, the leaves thicken and thin unevenly, forming foam spots, the leaf margins curled to the back, and the leaves are crumpled and distorted, showing a deformed shape, showing nicks. Or ribbon. Early onset, the plants were severely dwarfed, the internodes were shortened, the trees were not developed, and the leaves were not opened.
2. Cucumber Mosaic Disease: Infested by virus, the veins are transparent at the beginning of the disease, and they change into the mosaic, the leaves become narrow and twisted, the surface hairs fall off and lose their luster. Some diseased leaf margins often curled upwards, some appearing yellowish green or dark green foam spots, some leaf veins appear brown necrosis, or dark brown lightning necrosis along the veins. The plants are obviously dwarfed, and the roots are stunted. The leaves of the dead tree often appear as "flower bud burning spots."
