Boron (В) – is an important plant nutrient. It belongs to classic microelements. It is necessary for the normal growth and development of many crops, it is generally noted that more than 100 species of higher plants are in need of it. Its content in them reaches 0.0001% of the dry weight and usually ranges from 2 to 85 mg/kg (dry matter).
In plants, this micronutrient is distributed extremely unevenly. Usually about 90% of this element is found in green plant parts, that is, leaves and reproductive organs. Boron is found in all cell organelles. Its maximum amount is found in chloroplasts, nucleus and mitochondria. It has a versatile effect on plant. Boron increases the intensity of photosynthesis, activates respiration, and regulates the outflow of carbohydrates from leaves. At the same time, it is believed that a boron-carbohydrate complex is formed (complex sucroborates are formed), which easily penetrates membranes and cell walls. This element takes part in photosynthetic phosphorylation, formation of macroergic pyrophosphate ATP bonds and processes of cell walls formation. In addition, boron has a positive effect on biosynthesis of nucleic acids, thus supporting normal plant development. It activates a number of enzymes, such as sucrase, peroxidase, catalase, uridine phosphate glucogenase, transglucosidase, and several others. The main physiological role of boron stems from the fact that it takes part in exchange of phytohormones – auxins, activating auxin oxidase. Due to this micronutrient, growth of pollen tubes is enhanced; germination of pollen increases, number of flowers increases and ripening process takes place more soundly.


• Prevention and treatment of microelementosis diseases caused by boron deficiency (small grape berries, etc.)
• High efficiency of boron fertilizing with a maximum degree of absorption
• Increased resistance to various abiotic stresses and effects (heat, dry winds, drought, low temperatures, etc.)
• Activation of production and accumulation of proteins and carbohydrates
• Increased yield of various crops by 5-19%
• Improved yield quality (cucurbits, fruit, berries)
• Improved transportability
• Extension of shelf life
• Optimization of processes of respiration and photosynthesis under adverse and stressful conditions
• Improved development of regenerative organs, increased pollen fertility (increased amount of germinated grains, elongation of pollen tubes)
