Symptoms of tomato rot in the greenhouse
To ensure that the harvest was of high quality and quality, careful care, competent preparation of seeds and seedlings, constant inspection of all fruits andBush for defects. Why does a tomato rot?There can be a huge number of reasons for this problem, but you still need to know the signs of this disease in order to discover it as soon as possible and start a fight.
Vertex rot at the initial stage of education is almost not determined, and this brings difficulties, because to eliminate it at a later maturity, then more serious measures are needed.
As a rule, it manifests itself in the form of brown spots, it is easy to confuse with phytophthora. It should be noted that in addition, soon the top of the tomato will begin to acquire wateriness, and after a while, the fruit ceases to grow, and the place of formation of the disease gradually dries, smoothly turning, into the hollow of gray-brown color.
Further features are:
- Sealing of the peel;
- Deformation of the skin;
- Loss of shape;
- Shedding from twigs.
With minimal precipitation and too high a temperature, the fruit can on the contrary become more dense and elastic, and at high humidity, they literally absorb moisture, which makes them watery, and this leads to rot.
Why mass rotting tomatoes in the greenhouse
Tomatoes rotted on the vertex rot directly on the bush, and this problem can be of different types - fungal and agrotechnical. In the first variant, the fruit is affected by spores of fungi.
They can overwinter in the soil even at too low a temperature and, after planting the crop, get on the fruit by airflow. Most often, the infection comes from the seeds that were harvested from the infected tomato. In the second variant, rot occurs due to improper care of the crop and non-compliance with the recommendations.
As a rule, there are a number of reasons that can contribute to the formation of vertex rot on tomatoes. Sharp changes in temperature and weather conditions - for example, if a long time there was a drought, and then the rains began, it could become a kind of cold of culture. If the plant is planted in poor soil, then this leads to the formation of vertex rot. Most gardeners do not have an idea of what level of pH the kidney has. If too high acidity or vice versa, it leads to rot.
Potassium deficiency is very important for many summer residents and their tomatoes. During the cultivation of the culture, at least one use of calcium nitrate is required, which will avoid a collision with rot. If you use a large amount of nitrogen fertilizer, it will cause rot in tomatoes, almost all bushes. Owners themselves can cause the formation of vertex rot. For example, not many can perform regular daily watering of tomatoes and, therefore, coming for a weekend, literally begin to flood the culture. Such a drop in drought and increased humidity contributes to the development of rot.
There is also a downside to care. If it is too frequent, for example, constant loosening and weeding of the crop, it can also cause rot. In other words, the root system is damaged, after which stains may appear on the fruits in which the bacteria that lead to decay develop.
How to overcome gray rot on tomatoes in the greenhouse
Prevention significantly reduces the risk of infection, but it is also important to begin timely treatment. In order to preserve the tomato crop as best as possible, the fight with such a problem as gray rot should be carried out as early as possible and even before the formation of the peduncle.
- Choose varieties with resistance to this disease;
- Properly care for seedlings;
- Do not forget about preventive procedures.
If preventive measures are eliminated, then you can safely say goodbye to the whole crop, as prevention is the basis of high-quality and delicious tomatoes. To carry out preventive measures of vertex rot, it is necessary initially to create the most favorable conditions for cultivation, so that there is no dry and vice versa, too humid atmosphere.
This will help prevent the formation of fungus within the greenhouse and the greenhouse.
In general, the creation of favorable conditions for cultivation of crops consists in the selection of varieties that have resistance to fungi and in particular, to vertex rot. The conditions are reduced to the preparation of seeds for planting, preparing soil, observing the rules of additional fertilization during the growing of seedlings in the home, forming the right microclimate in the growing room.
Prevention and treatment of top rot of tomatoes in a greenhouse
The choice of a variety should be made according to the recommendations from the manufacturer, marked on the package. Basically, if tomato has resistance to various kinds of problems and diseases, it is always noted on the packaging with seeds.
should be correctly selected. The most suitable tomatoes of this type are:
- Borodino F1;
- White filling.
In the formation of apical rot, it is necessary to resort to actions that can eliminate the disease in a minimum amount of time and save the harvest. Most often, an infusion of wood ash is used. Initially, as soon as the first signs of the disease are seen, it is necessary to remove all affected tomatoes, and remove them from the greenhouse, and then begin treatment.
Ash contains components such as phosphorus, calcium, manganese and boron, which are the best and prevent many diseases of tomatoes, and help to eliminate them.
In addition, the ash is completely harmless and can not cause toxic poisoning to the culture. To replenish calcium, it is necessary to eliminate rot, or in other words, tomatoes with rot, and also use foliar feed supplementation with calcium chloride and calcium nitrate. Top dressing is carried out by spraying. No less optimal option is considered feeding with phosphorus, as it allows you to keep healthy tomatoes, but here the main thing is not to overdo it. Extraction from superphosphate is considered to be very effective.
