In order to harvest tomatoes as early as possible, many use greenhouses. But this method requires a lot of effort and is associated with great risks. After all, it is necessary not only to build a greenhouse correctly, to select the soil, to disinfect it in time, but also to monitor the air temperature, humidity, and regularly ventilate the building. In addition, it is necessary to observe the tomatoes very carefully from the moment of the first shoots. It is important to identify tomato diseases in the greenhouse and start treatment as early as possible. This is one of the main conditions for the care of these vegetables.

In order to increase productivity and prevent the emergence of diseases and pests of tomatoes, it is important not to forget about cult rotation. Do not plant tomatoes in the same place for several years. Swap them with cucumbers, peppers, or other vegetables. After the end of the harvest, it is necessary to remove all plants from the greenhouse and replace the topsoil. All wooden elements, film and glass must be disinfected with lime and copper sulfate. This will help prevent many tomato diseases.in the greenhouse.

One of the common problems is the infection of tomatoes with such a viral disease as mosaic. On the leaves, pale green spots alternate with he althy areas. Another common problem is streak disease. It manifests itself in the form of stripes and spots on fruits, stems, shoots. On tomatoes, keratinized areas of irregular shape are visible, and the flesh inside such fruits is brown, they are unevenly colored. These tomato diseases in a greenhouse develop very rapidly in cool and cloudy weather, but they can be prevented by alternating crop planting sites, taking seeds only from he althy plants known to you and disinfecting them with potassium permanganate before planting. It is also a good idea to cover them with foil to avoid transmission of the virus inside the greenhouse.

With high humidity and temperatures around 25oC, cladosporiosis (also known as brown spot) can develop. This fungal disease first affects the lower leaves, then spreads upwards, passes to the fruits. As a result, the tomatoes shrivel and fall off. Also, high humidity and temperature contribute to the appearance of chlorosis - Fusarium wilt. It usually appears during the fruiting period. You can prevent such tomato diseases in a greenhouse by monitoring the humidity, watering the plants only in the morning and removing any damaged shoots or even bushes.

In greenhouses, you can often encounter diseases such as late blight southernand gray mold. They are the cause of the appearance of brown wet spots on the fruits. Also on infected tomatoes there may be a gray coating of mold. It is clear that such vegetables are no longer suitable for eating.

If you notice that something is wrong with your seedlings or fruits, then it is better to look at the pictures of tomato diseases in the greenhouse. Photos of affected plants and fruits will allow you to more accurately determine the disease and decide on further actions. True, not always novice farmers can cope with this task on their own. But this will not be difficult for you if you have been growing tomatoes for many years. Diseases, the treatment of which is not a problem for a specialist, will recede. It will be enough just to inspect the plants to assess the scale of the problem and talk about methods of prevention and control of the disease.
