It is the most popular cut flower in the world, second only to chrysanthemum, accounting for about 17% of the total cut flower production. In all indoor cut flower production, carnation has the highest output per unit area, which can be mechanized and automated for large-scale production. Therefore, the price of carnation is relatively low. Carnation is widely used.

Control of three major diseases of carnation
Leaf spot, Fusarium wilt and virus disease are the main diseases in carnation. The control methods are as follows: leaf spot mainly infects leaves, and most of the diseases start from the lower leaves. The seriously diseased part of the plant was twisted, and the diseased leaves withered and hung upside down on the stem, but did not fall off. The disease of old leaves is more and more serious than that of new leaves, and the disease of open field cultivation is more than that of greenhouse. Prevention and treatment methods: from the initial stage of the disease, regular spraying; immediately after picking buds and cutting flowers, fungicides should be sprayed to protect them. Use 75% chlorothalonil wettable powder 800 to 1000 times liquid spray

Carnation white silk disease
Shanghai, Hangzhou. [symptoms] the disease occurs at the base of the stem near the soil surface and turns brown and rotten; the diseased stem tissue is cut and tea-brown or dark-brown rot develops to the center from the outside; the xylem also changes color upward, and the pinnately radiating white hyphae can spread to the surrounding soil surface; then sclerotia the size of initially white and later yellowish-brown rapeseed is formed on the diseased part and surrounding soil surface mycelia. After the plant is susceptible to disease, the whole plant usually loses and dies. On the cutting bed, wet rot occurs from the healing and forming area of the cuttings, which can also cause serious roots.

Prevention and control measures of carnation virus disease
a. The imported carnation seedlings should be strictly quarantined to avoid the spread of infected seedlings. b. In the large-scale production base, the virus-free mother garden was established by using stem tip virus-free seedlings for strips propagation. c. Try to remove the susceptible plants and reduce the infection source. In the process of picking, cutting flowers and pruning in cultivation management, attention should be paid to the disinfection and cleanliness of operating tools to avoid contact and infection. d. Pay attention to the prevention and control of vector aphids. 1500 times of 50% aphid pine wettable powder or 5000 times of 2.5% deltamethrin EC can be sprayed to kill aphids. e. Hot spot

Virus disease of carnation
Carnation virus disease is a worldwide disease, which occurs in all cultivated areas. The common virus diseases are leaf vein mottle disease, necrotic spot disease, erosion ring disease and latent disease. the virus often causes carnation growth weakness, short flower branches, smaller flowers, mixed petals, split calyx and so on, which seriously affect the quality and yield of cut flowers. The main results are as follows: (1) Carnation necrotic spot disease: the leaves in the middle of the susceptible plant become gray, yellowish necrotic mottled, or irregularly shaped stripes or stripes. The lower leaves often show purplish red stripes or stripes. With the plant

wilting of carnation
[Symptoms] The external symptoms of this disease are very similar to those caused by Fusarium wilt. The leaves of the diseased plants turn gray-green, then yellow, and dead tops appear. The plants wither and die due to the rupture of the stems. A yellow to light brown stripe can be seen when examining the central column. At the same time as the aboveground disease, the root also disintegrated. The occurrence of the disease can be divided into two situations: acute type develops rapidly, especially after the young plants on the hotbed are damaged; when the damage is slight, the leaves are twisted.
