Resistant varieties of tomatoes for open ground. Choosing the best tomatoes that are resistant to late blight for the suburbs
To get a good and high-quality crop of tomatoes, it is necessary not only to care for the plants, but also to choose varieties of tomatoes that are resistant to diseases. Like most garden crops, tomatoes are influenced by pathogens (viruses, fungi, nematodes). In most cases, plants are affected by infecting seeds or applying infected organic fertilizer to clean soil. Often the soil itself becomes the causative agent.
The development is facilitated by the favorable conditions that are created in greenhouses or in the open field. These conditions include: loss of moisture balance, excess of certain types of fertilizers, cold, dampness or heat.
Many summer residents, guided by their many years of experience, carry out a number of preventive measures to prevent many diseases:
- Seed treatment with potassium permanganate before growing seedlings.
- Soil treatment with copper-containing agents and preparations.
- Full change of soil in the greenhouse or the location of the beds in the garden.
Given the characteristics of each disease, breeders began the development of hybrid varieties of disease-resistant tomatoes. This work continues to this day.
As you know, seeds of hybrid tomatoes should be bought only in specialized stores. The collection of seeds from them with further planting in seedlings next year, may not bring the desired yield, because such an important factor as the maternal line is lost.
According to reviews, most varieties of tomatoes are resistant to such a dangerous disease as phytophthora. This fungal disease affects leaves, stems and even the fruits of tomatoes. It develops with an excess of moisture in the greenhouse, or in open ground with prolonged rain. Tomatoes that are resistant to late blight, can be found among the tall (indeterminate), and among the undersized (determinant) varieties.
In order not to worry about the destruction of tomato bushes by pathogenic microorganisms, bacteria, fungi, many summer residents choose those varieties that are most resistant to diseases.
