Phosphorno - Potassium plant growth regulator with cryoprotective properties "Antistress", Dnipropetrovsk region.

Climatic stresses of various kinds (frosts, atmospheric and soil droughts) cause great damage to agriculture. Losses at the same time are estimated at billion UAH.
To solve this problem, an effective and at the same time inexpensive, ecologically clean drug "Antistress" was developed.
The drug quickly penetrates the cell of the plant and ensures the full supply of nutrients contained in the drug. Once inside the cell, they are included in the physiological processes taking place in it, thus increasing the activity of enzymes, activating the processes of respiration, the synthesis of proteins and carbohydrates, activating the processes of forming the area of the leaf apparatus, increasing the productivity of photosynthesis.
To obtain stable crops, it is necessary to increase the adaptive capabilities of plants to extreme conditions that can be created by climatic factors. This can be achieved by using physiologically active substances. They create a certain biochemical environment around germinating seeds, are growth stimulators and regulators, and increase the resistance of seedlings to diseases and adverse environmental conditions.
Foliar treatment of plants increases the resistance of plants to the adverse effects of the external environment, ensuring adaptation to changing environmental conditions, i.e. has a stress-corrective effect until the end of the growing season. Provides the plant with readily available phosphorus and potassium under adverse conditions for 21 days.
APPLICATION PHASES:
- in autumn (2 - 3 weeks before frost):winter wheat, winter barley - in the tillering phase; winter rapeseed - in the phase of 4 - 6 true leaves;
- in spring: winter and spring wheat, barley - in the tillering phase,corn - in the 5-7 leaf phase,sunflower - in the phase of 6-8 leaves, rapeseed - in the phase of 6-8 real leaves.
Correct and timely application of the drug guarantees an increase in frost and drought resistance of plants by 25%-30%. Keeps a prolonged action for the entire vegetation period.
MAIN COMPONENTS AND THEIR PROPERTIES

MAIN COMPONENTS AND THEIR PROPERTIES
A polymer preparation containing humic acids in its composition. The composition of the preparation includes the products of the metabolism of the endophyte symbiont fungus: auxins, cytokinins, gibberellins, unsaturated fatty acids, vitamins (mainly group B), amino acids, enzymes, lipids, phytolexins, and other physiologically active substances that, first of all, stimulate the development of the root system, and subsequently provide balanced nutrition of agricultural crops.
The preparation also includes humic acids. They are considered a good growth stimulator, an energy accumulator and a source of nutrients, they contain more than 20 trace elements.
Dimethylsulfoxide (DMSO) is one of the well-known cryoprotectant solvents, it stimulates the activity of enzymes of antioxidant protection, which can be reduced due to the influence of adverse factors on the plant. It slows down the destruction of bio-oxidants under conditions of low-temperature stress, contributes to the resistance of plants to low-temperature effects.
The natural barrier (membranes) is the first to be exposed to stress factors. DMSO, being an excellent antioxidant, significantly increases the flexibility and elasticity of membranes, thereby facilitating the passage of substances through the plasmalemma, making it resistant to the negative effects of stress factors.
The combined mixture of polyethylene glycol and DMSO is easily included in the reaction of carbon synthesis, during the breakdown of fats during the period of autumn tempering. But since cereal seeds contain little fat and a lot of starch, in addition to this, glycerin goes to the formation of fat from fatty acids formed during the hydrolysis of starch. The use of the specified substances leads to significant changes in the metabolism of plants for a long time, which ultimately leads to a significant increase in frost resistance, drought resistance, productivity and quality of production.
Phosphorus (P2O5 - 31.76% in 1 kg of the drug), which is part of plant proteins, nucleic acids (RNA + DNA) and energy carriers ATP, plays a major role in regulating the water regime of plant cells. Accelerates the development of plants, improves the quality of production.
The greatest effectiveness of phosphates in comparison with other nutrients is noted in the steppe zone and in the dry period. Optimal phosphorus nutrition stimulates the development of the root system: it branches more strongly and penetrates deeper into the soil. And this, in turn, contributes to the improvement of the supply of plants with nutrients and moisture, which is especially important in dry periods.
With foliar fertilization with liquid fertilizers containing phosphorus, its movement into the root system is noticeably accelerated. Normal phosphorus nutrition is provided.
Potassium (K2O - 20% in 1 kg of the drug) is the main component of the nutrient that increases productivity. It has a positive effect on the resistance of plants to drought and fungal diseases, allows plants to use water more economically and productively, participates in carbohydrate and protein metabolism, and in the activity of enzymes. Good potassium nutrition improves the quality of production (increases the content of carbohydrates - sugar, starch, fat).
In the end, the task of the drug is to accumulate the maximum amount of sugars in the plant by the beginning of frost, to provoke the process of compaction, to increase the strength and elasticity of the cell walls.
Soluble sugars, especially sucrose, glucose and fructose, play a central role in the structure and metabolism of both individual cells and the entire plant organism.(//tractor-service.com)
Advantages of the drug:
- all components of the drug strengthen the action of each, which significantly improves its work;
- due to the increase in the content of monosaccharides in the plant (by 15-20%), water and juice bind in the intercellular space, and this prevents the formation of ice crystals in the cell (the plant tolerates frost more easily);
- the membranes become elastic, the regulation of water exchange is better (the plant tolerates drought more easily);
- the immunity of plants and resistance to diseases increases;
- the productivity of plants increases, the yield increase is 2.5-4.0 t/ha.
