Like any other plant, tomatoes can easily be exposed to various diseases, it can be fungi, a variety of viruses that affect only plants, mold or nematodes. Often, infection occurs if the virus penetrated the seeds or if the disease hit a fertilizer that was introduced into clean soil. It is the soil that can become the only method of infection of a tomato plant, so it is necessary to select varieties of tomatoes for greenhouses resistant to late blight, in this case they will be healthy and bring a rich harvest.
As already mentioned, the carrier of the disease can be exactly the soil in which the seedlings are planted, and since small plants are often placed in greenhouse conditions, this only contributes to the spread of the disease, since the greenhouse is always quite warm and humidity is high. If the plants are grown in the open ground, the appearance of diseases can contribute to the extra fertilizers that were applied to the soil, the wrong percentage of soil moisture, cold and wet soil, and also too hot weather. In some cases, gardeners not only select tomato varieties for the greenhouse that are resistant to late blight (the video is worth a look), but also carry out additional activities that help seedlings to avoid a variety of diseases, including late blight.

I would like to note that the collection of seeds of such plants will not bring any sense, since most likely the tomatoes will no longer have the same properties, it is best to purchase other seeds and plant them again in the ground, which is why it is advised to leave packs of seeds to choose already proven varieties and manufacturers.
If you know the feedback from experienced gardeners, then they have already been able to identify the best varieties of tomatoes that perfectly resist late blight and other diseases. Phytophthora is considered a dangerous disease, since it spreads with the help of fungal spores and destroys both small seedlings and adult bushes. It can affect not only the stems and leaves of the plants themselves, but also affect the tomato fruits. Most often, this disease can affect the plant if it grows in greenhouse conditions with an increased percentage of moisture. If the disease affected the plant in the open air in the ground, then the reason for this may be too long rainy days, due to which the soil was moist and cold for too long.I would like to note that today both tall and tomatoes are grown, in which the bush has a low growth, they can perfectly cope with this fungal disease.
