Tomato is an amazing vegetable. After all, from it you can cook various salads, sauces, frying and much more. For this, the tomato has become widespread throughout the world, and therefore its cultivation is carried out at an active pace both outdoors and in greenhouses. Although the process itself from sowing to harvesting is not so complicated, various diseases of tomato seedlings can cause a lot of trouble. Therefore, it is important to keep them away from plants or destroy them at the first manifestation.
Diseases of tomato seedlings: late blight
This disease is the most insidious of all, because it spreads both through the seeds of the plant, and through infected soil or tomato fruits that have been left in the beds, or even by airborne droplets. The latter mode of transmission is difficult to control, but minimizing transmission is still possible.
Late blight manifests itself if the soil is not saturated with useful trace elements (iodine, manganese, copper, potassium) and various nitrogenous fertilizers. nitrogen, potassium andwith phosphorus, it is necessary to water the plants directly under the root, but it is best to spray with microelements, since the bush will better accept them through the leaves. Biological protection will help prevent this disease of tomato seedlings, that is, sowing plants such as garlic and onions next to the tomato on both sides of the beds, and savory and basil can be planted along the edges. You should also beware of placing cucumbers, dill, peas next to tomatoes; instead of them, it is better to plant cabbage, beans, lettuce or radish nearby. It is also necessary to observe the correct distance between the individual bushes of the plant.
There is a good recipe for protection against late blight for seedlings: Fitosporin-M powder (30 g) is diluted in 10 liters of water and poured into 200 ml holes, the same preparation is then sprayed every 7-10 days. If this does not help, then only fungicide treatment remains.
Tomato seedling diseases: fungi and viruses
The tomato has many fungal enemies. The main ones are those that cause tomato diseases (photos No. 2 and No. 3), such as black leg, white and brown leaf spot, black bacterial spot. Viruses include streak and mosaic.
The black leg reveals itself by thinning the stem just above the root. If such signs are found, then you should sprinkle the beds with river sand (1-1.5 cm), and also monitor the level of temperature and moisture.
Such tomato diseases, the leaves of which become stained, are also very dangerous. The first step is to carry out disinfection measures for all inventory, but if such a disease has hit the plant, then it is better to destroy it.
With white spotting, you can try to save the life of a bush if you use a Bordeaux 1% mixture. With black, a fungicide with copper can help. In the case of bacterial spotting, everything is also disinfected and treated with fungicidal solutions. It will not be lucky if the streak virus becomes the cause of the tomato seedling disease: the plant is usually destroyed, and if necessary, the entire crop, since the seeds and future bushes will already be infected. Mosaic is also an intractable disease. Spraying with urea (10 liters of water, 1 tablespoon of urea and 1 liter of skimmed milk) every 10 days can help here. However, severely diseased plants will have to be destroyed. In general, the best remedy for viral disease of tomato seedlings is to use only he althy seeds, well-cultivated soil, and decent care.
