"ROSTOK" Ovary is a liquid, highly concentrated, complex chelated microfertilizer with a high content of nutrients.

Fertilizer is used for irrigation and foliar feeding of vegetables, fruits , berries and ornamental crops.

The fertilizer contains macro nutrients, trace elements, amino acids, carboxylic acids, humic substances and an adhesive.


- promotes the formation of a powerful root system;

- increases the resistance of plants against diseases and pests;

- promotes intensive laying of generative organs;

- improves the formation of the ovary and prevents it from dropping, especially in adverse weather conditions and the absence of pollinating insects;

- improves the outflow of plastic substances to the productive part of plants during the ripening period of the crop;

- accelerates uniform ripening of the crop for 5-7 days;

- increases crop yield up to 25%.

Also, in addition to improving the growth and development of plants, depending on the culture, it is recommended to make "ROSTOK" Fruiting, "ROSTOK" Macro, "ROSTOK" Iron, "ROSTOK" Zinc, etc.

Внекорневые подкормки:

Порядок приготовления рабочего раствора:

1. Резервуар опрыскивателя наполнить на 2/3 объема водой, добавить карбамид (при необходимости), включить мешалку;

2. Добавить по очереди макро- затем микроудобрения «УАРОСТОК»® и препараты защиты растений (если они предусмотрены и рекомендованы, после их предварительного смешивания и опробования);

3. Дополнить резервуар водой до полного объема и приступить к опрыскиванию.

Капельное орошение: используют рабочий раствор концентрацией 0,006 - 0,01%.

"ROSTOK" Ovary











Approach of using and consumption rate:

Foliar feeding: in this way elements are absorbed from fertilizers by plants at 95-100%. Consumption rate of working solution is 200-300 l/ha.

Root feeding: conduct in circumstances where there is no possibility to conduct foliar fertilizing, spreading fertilizer 0.8-1 liters per 100 liters of irrigation water.

Drip irrigation: working solution is used in concentration 0,006-0,01% (60-100 ml per 1000 liters of water).

The value of fertilizers "ROSTOK" Ovary: in most cases due to adverse soil and climatic conditions fruit formation process is broken, so to grow healthy plants, you need to apply a comprehensive micronutrient chelate-based "ROSTOK" Ovary, which is used to stimulate fruiting plants,  accelerate their growth and development, the formation of a high and early harvest with good quality. Fertilizers containing in its composition specially selected set of trace elements in quantities that ensure maximum impact on plant productivity.

Sulfur (S) is a component of proteins and plays an important role in protein metabolism in plants, part of the enzymes, increases chlorophyll content and improves phosphorus supply, increases efficiency amide nitrogen. In case of shortage, like the lack of nitrogen, chlorophyll is destroyed, increasing the threat of fungal diseases.

Iron (Fe) plays an important role in redox reactions as a component of enzymes provides a synthesis of chlorophyll. Is important to the process of breathing. Lack of iron leads to a decrease in the intensity of photosynthesis,  in young plants observed chlorosis. It prevents the absorption of iron.

Manganese (Mn) affects the passage of photosynthesis, respiration, protein synthesis, carbohydrate and nitrogen metabolism; improve the usage of nitrate and ammonium nitrogen; increases frost resistance and winter hardiness of plants, increases productivity.

Boron (B) has an important function in the synthesis of carbohydrates and their transformation and transportation, as well as redox processes, protein and nucleic metabolism, synthesis of growth factors, causes the activity of enzymes, vitamins accumulation in plants; promotes the synthesis of chlorophyll and assimilation of CO2; increases drought, frost resistance of plants; affect the differentiation, growth and cell division, as is an integral element of their walls.

Zinc (Zn) is involved in many physiological processes that occur in plants, particularly in photosynthesis, the synthesis of amino acids, chlorophyll, organic acids, vitamins, etc., in redox processes, carbohydrate, lipid, phosphorus and sulfur. By stabilizing the breathing changes temperature conditions, this trace element improves heat resistance, drought tolerance and hardiness of plants resistant to disease lesions. Zinc prevents the absorption of high standards of nitrogen, phosphorus and lime and low soil temperature.

Copper (Cu) positively affects photosynthesis and protein synthesis, formation of generative organs, resistance to fungal and bacterial diseases, increases drought resistance, heat resistance and winter hardiness of plants and their resistance to lodging; promotes better assimilation of nitrogen. Lack of copper predetermined high standards of mineral fertilizers, liming soils, high soil temperatures and air.

Molybdenum (Mo) is involved in the synthesis of amino acids and proteins that regulates the transformation of nitrogen in the plant, activates the passage of redox processes in plants, is involved in carbohydrate metabolism and in the metabolism of phosphate compounds, synthesis of chlorophyll and vitamins. It increases the protein content in the product. Especially effective is the use of molybdenum in acidic soils.

Cobalt (Co) positively affects the synthesis of chlorophyll in the leaves of plants, increases respiration rate, which significantly increases yield crops and improve their quality, increases levels of proteins, fats, sugars and vitamins.

The use of fertilizers "ROSTOK" Ovary helps:

• formation of a strong root system;

• increase plant resistance against pests and diseases (eg to late blight - in 4-6 times, septoria - in 1,5-4 times macrosporiosis - 2-4 times);

• intensive laying of the main organs;

• formation of ovaries and prevent it of falling, especially in adverse weather conditions and lack of insect pollinators;

• outflow of plastic substances to productive parts of plants during the ripening of the crop;

• accelerate uniform ripening harvest 5-7 days;

• increase the yields by 10-20%.

General recommendations: it is expedient to prepare tank mixtures of urea and crop protection liquids (if necessary). Foliar feeding of plants is better to perform before 12 th hour of the day or after 17 o'clock in the evening during the phases of growth and development of crops that are most sensitive to the provision of micronutrients. Not recommended for handling during the day when it is scorching sun or windy weather. Evening or morning dew on the efficiency of feed is not affected! The water temperature for preparation of the working solution should be close to the ambient temperature (not recommended to perform the processing with cold water, dialed directly from the well, as is the likelihood of stress in plants, which contributes to the development of disease, cessation of plant growth and their death).

Security measures: The product is non-toxic to humans and bees, not allergenic, environmentally safe, by the classification refers to the 4 groups which represents non-hazardous substances. While working with the drug, you should observe accepted security measures.

Equipment: 1 liter, 5 liters, 10 liters, 1000 liters.
