Before sowing tomato seeds should be carefully selected, treated with solutions of potassium permanganate, hydrochloric acid.

Often tomato diseases associated with the violation of plant cultivation conditions: high humidity and temperature, which are the ideal environment for the development of disease-causing organisms, proximity to potentially dangerous cultures. With a lack of moisture, tomatoes dump all their flowers and small fruits, the stems acquire a yellowish hue, they can twist.

It should be remembered that tomatoes can be planted on the same soil where the nightshade( potatoes, peppers) did not grow earlier than in a few years. The best predecessors for a tomato will be perennial grasses, annual wheat, beans. In addition, the cause of the development of gray rot can be acidic soils in the greenhouse.

Protection of seedlings from damage caused by fungal and viral diseases includes the replacement of soil in the greenhouse, cultivation of the soil.

Also tomatoes suffer from improper or excessive fertilization: an abundance of fertilizer in the soil can lead to the twisting of plant leaves "in the tube".In addition, plants can begin to "fatten": direct all nutrients to thickenings and development of the stem, the growth of shoots, and not fruits.

Cladosporium, mold, rot are treated using the whole complex phytosanitary, agronomic and chemical methods: crop rotation, the collection and destruction of infected plants, maintaining the optimal level of humidity and temperature( avoid sudden changes in temperature in the daytime and at night, increasing the air humidityIn more than 70%), spraying the plants with the same fungicides as against the phytophthora.
