Spraying tomatoes with iodine serum: proportions for processing

The content of the article

Among tomato pathologies, there are often intractable and insidious, for example, fungal infections such as late blight. He is capable of destroying all vegetable plantings in a short time, depriving the summer resident of the crop. To combat fungus and other diseases, gardeners use serum with iodine.

What is useful for plant serum

Milk, as the basis of the product, is ideally suited to tomatoes during their growth, when the need for culture is especially high. Fertilizing based on a dairy product contains a lot of useful substances that positively affect the development of culture. These include:

  • lactose (detrimental to pests);
  • potassium, copper, phosphorus, calcium, iron, manganese, other trace elements;
  • amino acids (activate vegetable growth).

After processing with milk, a film forms on the leaves of tomatoes, which protects the plant from fungi and insects. Spraying tomatoes with iodine serum has such positive effects:

  • the process of assimilation of useful substances that are contained in the soil is accelerated;
  • metabolic processes improve;
  • increasing the efficiency of fertilizers such as compost, etc..

  • improved survival after planting and germination of vegetables;
  • strengthening immunity, improving tomatoes;
  • yield increase;
  • providing fruits with greater benefits;
  • improving the maturity of ripe vegetables.

Spraying rules

You can use whey for tomatoes growing both in open ground and in greenhouse conditions. Spraying is carried out at a certain time and taking into account such rules:

  • in the absence of active sunlight (morning or evening);
  • in dry weather, without wind and precipitation;
  • using a finely dispersed atomizer (it is important that the product covers all the leaves of the plant);
  • at a temperature of about 17-19 degrees.

The first spraying is carried out 2 weeks after planting the tomatoes in the garden. Further, the processing of the vegetable crop is repeated twice a month. If there are signs of late blight or another disease, serum spraying can be carried out daily. The best time for the treatment and prevention of tomato pathologies with a dairy product is the beginning of July, when plants are in dire need of amino acids for growth.
