As we all know, living things are made up of cells. But in nature there is also an organism that does not have a cellular structure. This is the virus. The virus is very small, but the damage to the flowers is great.
Come to know about the virus
General bacteria can be seen with an optical microscope. The virus's original appearance can only be seen with an electron microscope. In the body of the virus, there is no structure such as a wall, a membrane, or a substance. It cannot be an independent life at all. Only by entering organisms such as flowers, can other organisms be preyed to survive. Once many viruses have left the organisms on which they depend, they will soon die.
Viruses cause disease in flowers
The characteristics of flowers caused by viruses are obvious, mosaics and deformities are the most common.
Mosaic
Mosaic means that the leaves of the flower change from uniform green to yellow and green. After the flowers are damaged by viruses, they will produce mosaics, such as violet leaf disease, dahlia mosaic disease, rose mosaic disease. When the flowers are iron-deficient and magnesium-deficient, they also form mosaics. Virus caused by mosaic leaves, yellow veins, and iron deficiency, magnesium deficiency caused by mosaic veins are not yellowing.
deformity
Viruses cause a variety of deformities in flowers, such as leaf shrinkage, branchlets, dwarfing, and so on.
Prevention of Flower Virus Diseases
The first and foremost is to reduce the amount of flowers used to buy flowers and pay attention to the observations. Do not pick flowers with viral diseases. During the cultivation process, the virus disease should be treated as soon as possible.
Avoid or reduce friction and insect repellent Most flowers and virus diseases will be transmitted through the friction between the leaves and the branches. Attention should be paid to avoid or reduce the friction of the leaves. There are also some viral diseases that are transmitted by insect pests such as roundworms, so insects should be taken care of.
After spraying the flowers to find the diseased flowers, spraying a little potassium dihydrogen phosphate on the plants can increase the disease resistance of the plants and reduce the incidence. Virus A can also be purchased at a pharmacy and sprayed.
