Greenhouse Tomatoes Resistant to Phytophthora – Varieties

Like any other plant, tomatoes are susceptible to various diseases, including fungi, various viruses that affect only plants, mold, and nematodes. Infection often occurs when a virus enters the seed or when the disease is introduced into the fertilizer applied to clean soil. Soil can be the only source of infection for tomato plants, so it's important to select greenhouse tomato varieties resistant to late blight. This will ensure healthy growth and a bountiful harvest.

As mentioned earlier, the soil in which seedlings are planted can be a carrier of the disease. Since small plants are often placed in greenhouses, this only facilitates the spread of the disease, as greenhouses are always quite warm and humid. If plants are grown outdoors, the development of diseases can be facilitated by excessive fertilizers applied to the soil, improper soil moisture levels, cold and damp soil, and excessively hot weather.
