The best ways to treat tomato vertex rot in the greenhouse

It cannot be considered a non-communicable disease or rot affecting a tomato in a greenhouse. First of all, this reduction in harvest by almost a third, which may entail a decline in income, if tomatoes were grown for commercial purposes. But if you observe the simple preventive measures during their cultivation, you can prevent a lot of trouble, one of which is top rot. We will describe the ways to combat and treat this scourge in the article.

Contentsmode, insufficient moisture .Scientists believe that this is the main reason. On dry and hot days, moisture evaporates from the foliage, the roots are not able to replenish the plant in time with the right amount of water. The consequence of this is the outflow of water from the fruit to the leaves, from which a certain number of tomato cells simply die off;

  • low calcium in the earth. On such a land, the appearance of top rot is most likely;
  • hazard and saline land areas .
  • Gardeners are often to blame for the appearance of the disease. They did not take care of the balance of mineral components in the soil, irrigating irregularly.

    Disease variants

    The disease may be twofold, associated with fungal or agrotechnical origin. Tomatoes can be affected by fungal spores in the ground and transmitted to the healthy shrubs through the air.

    Very often, an infection occurs through the self-collected seed

    . Bushes often become infected with with seed, which was harvested from affected tomatoes. In this case, the disease is caused by violations in the care of plants.

    Non-infectious variety

    is caused by an insufficient amount of calcium, disturbances in irrigation, and sharp changes in the temperature regimes of at night and daytime.

    The affected part of the tomato does not soften, the fabric acquires a dark brown shade, sometimes even black. When treating a culture, it is necessary to organize control over the air temperature in the greenhouse, air it, properly water the plants using warm water.

    Non-infectious vertex rot

    Bacterial variety

    Its main cause is bacteria. The disease manifests itself already in the initial phase of growth. As humidity increases, the affected areas of the become softer, and the special smell of appears.

    The pathogen can be carried by solanaceous crops or insects. Often, the pathogen is already in the seed material, so that it will be necessary to deal with top rot from the moment of sowing. It is only necessary to soak the planting material in a manganese solution in order to disinfect it.

    If greenhouse tomatoes have vertex rot, carefully remove all plant residues and burn them.

    Methods of control and treatment of vertex rot

    Methods of protecting tomatoes from this disease are fully determined by the causes of its appearance - dry soil and lack of calcium.

    It is necessary to to irrigate in a timely manner, not to bring the soil to dry and overheat. Top dressings of foliar nature are also used, in which special formulations are used.

    If the plants lack calcium, an excellent solution would be to treat the plants with preparations containing boron and calcium in addition to nitrogen, phosphorus and potassium. This mixture acts synergistically, the components increase the activity of each other.

    Another measure is the chemical preparation Brexil Ca containing up to fifteen percent of calcium and half-percent boron. It is used during foliar dressing, diluting with water at the rate of ten grams per ten-liter bucket. The procedure is recommended once every fifteen days.

    Do not neglect the liming of - an excellent measure that helps saturate the soil with calcium. It is best to perform this procedure in the autumn when the harvest is fully harvested.

    One of the means of controlling the disease is Calcium Brexil

    . Preventive measures

    The main way to control it is to prevent the disease. First of all, you should not create favorable conditions for it.

    To do this, you must:

    • choose for growing plants moisture-receptive land .If the soil in the greenhouse is too light, it is necessary to add peat and turf soil to it, which will help retain water;
    • should not be on the eve of planting make a lot of fertilizer formulations, so as not to overfeed the culture
    • should not be planted in the greenhouse bushes too thick. Tomato plants need to stepchild and form in a timely manner;
    • watering should be carried out regularly, using a sufficient amount of moisture;
    • using mulching will be a good opportunity to retain moisture in the soil, only the layer will have to be changed once a week. To do this, fit grass, nettle, weeds without seeds, compost, dry straw, covering material in white;
    • in hot weather should be to air the greenhouse , pritenit plants with a white cloth. If the greenhouse is made of glass, then it can be whitened with lime.
    Mulching is one of the ways to prevent vertex rot

    Other sources of infectious disease are water, soil, solanaceous weeds, harmful parasites .So comprehensive measures for any bacterial diseases will be appropriate. This is especially important if in the past years on the landings such diseases have already been noted.

    Such activities should include the collection and destruction of plant residues affected by tomatoes, the control of harmful parasites and weeds, the maintenance of crop rotation and the alternation of plants.

    If there is no possibility to alternate crops, it is recommended to sow sideratta plants on beds between seasons, which after growing will be embedded in the soil.

    Greenhouses, in which there was a tip rot on tomatoes, are aired, disinfected, and the ground in them is completely changed.

    Using the above recommendations, you will be able to perfectly protect your tomato plants from vertex rot, to ensure normal conditions for their growth and development. In this case, you can be sure that the culture will reward you with a good harvest.
