What is mosaic virus?
Solanaceae such as potato, tomato, eggplant, and peppers, among other herbaceous or woody plants. It can also affect legumes, vegetables, and vegetables, like onions, beans, celery and soy, and so on.
Notably was the first discovered virus, although since the late 19th century until 1930, it was known that there was an infectious disease that damaged crops snuff and tomato, but could not be determined that the infectious agent was a virus.
Although the mosaic virus does not destroy the plants completely, yes weakens. This virus infection generates characteristic spots on the leaves of plants and also leaves wrinkles are perceived.
History mosaic virus
In 1883, the chemist Adolf Mayer made a description of the mosaic virus, indicating that this could move from plant to plant similar to bacterial infections. However, six years later, naturopathic, and Dutch botanical microbiologist Martinus Beijerinck showed that a culture medium and filtered free of bacteria continued to the infectious agent.
Already in 1935, biochemist Wendell Meredith Stanley crystallized the virus and managed to prove that it was still active after crystallization. In 1958, the crystallographer Rosalind Frankin, who worked for Stanley, said the virus was not solid but hollow and hypothesized that ribonucleic acid snuff mosaic virus was simple braiding.
What are the symptoms of mosaic virus?
The most characteristic symptoms of snuff mosaic virus are fading between the veins of younger leaves will subsequently increase to form the typical mottle virus; brown spots on the skin and pulp of the fruit; dark spots on the stems and petioles of the leaves; the lack of development of the plant; and bent, stretched, wrinkled appearance, especially when it is very hot and dry.
How it is transmitted and snuff mosaic virus treated?
He snuffs mosaic virus is through contact, ie, through contact plant with tools that are contaminated, or by the hands of workers.
As for treatment, it is important to make clear that it has, and there are varieties that resist this kind of mosaic, so it is important to take proper prevention to prevent infection mosaic virus.
- Use secured copies that are free of viruses or that are resistant to these. Buy them in specialized nurseries.
- Prevents access of animals that are contaminated plants using a barrier, cones, meshes, etc..
- Plantations carried away from areas with vegetation infested with whiteflies, aphids, thrips.
- Used chemical insecticides or natural vectors to deliver transmission.
- Removes the affected plants or entire plantation if necessary and burn.
- Remove the grass from the ground to eradicate the virus.
- Disinfects all work material to remove possible viruses on the tools you use on other plantations.
- Avoid growing susceptible plants to be invaded by a mosaic viruses in soils where they have been other contaminated plants. However, if you have no alternative and you’ll plant them in the same place, renews the soil up to 30 centimeters deep.
