One of the important methods of preparing for planting potatoes is the treatment of tubers with protectants and growth stimulants. The task of the reception is to protect the emerging plant from harmful objects (diseases and pests) and help it begin to actively grow and develop. Harmful objects on tubers are easily dealt with by pesticides - chemical disinfectants, and growth processes will help to activate growth stimulants based on components of natural origin, enriched with minerals.
The stimulating effect on the plant organism is primarily exerted by growth phytohormones: auxin, cytokinin, gibberellin. All of them affect the growth and division of cells, the processes of aging and adaptation, the transport of substances, respiration, the synthesis of nucleic acids, proteins, etc. At the same time, each group of phytohormones has its own specific functions: auxin is responsible for starting growth processes; cytokinin - for cell division, an increase in the volume of the root system, the formation of nodal (secondary) roots; gibberellin is necessary for abundant flowering and ripening of the crop.
Influence of auxins on the development of the root system:
- start of growth processes;
- the emergence of root tubercles;
- cell growth and differentiation (their specialization).
The influence of cytokinins on the development of the root system:
- cell division, increase in root volume;
- cell life extension;
- overcoming stress;
- increased influx of nutrients;
- an increase in the length and mass of the primary and secondary root systems.
Ensuring comprehensive plant protection for a long period largely depends on the correct selection of a protectant, but it is equally important to use a suitable biostimulant. A stimulant with a balanced composition of phytohormones, amino acids and nutrients helps to reduce plant intoxication, ensures the friendly germination of tubers and the formation of a powerful root system. A well-developed root system provides an improved nutrition regime for the plant, which allows the formation of a larger number of stems, which, in turn, leads to an increase in the number of stolons, which means that it directly affects the quantity and quality of the crop, and, accordingly, the economic efficiency of growing potatoes .
Super-Agro is a professional distributor of fertilizers, agrochemicals and biostimulants. Conducting a large number of laboratory and field experiments on the comparative testing of the effectiveness of the use of various fertilizers and biostimulants in crop growing technologies, the company's specialists select the best agrochemical tools for intensive farming in their assortment.
For pre-planting treatment of potato tubers, we recommend using a mixture of disinfectants + Sprintalga (0,2 l/t) + Fulvumin (0,3 l/t) + Ikar Perfectstick (0,01 l/t). This scheme is ideal for initial processing of tubers through any planting machines, including GRIMME professional planting complexes.
Sprintalga (Biolchim, Italy) is a professional organo-mineral root formation stimulator based on highly concentrated extracts (72%) of Macrocystis, Ascofillum nodosum and Sargassum seaweeds. Thanks to its special formula, Sprintalga supplies a large amount of biologically active components (betaines, alginic acid, trace elements and natural growth hormones) and amino acids that stimulate the primary metabolism and optimize the hormonal balance in young roots. As a result, Sprintalga stimulates the rapid formation and lengthening of roots.
• Phytohormones auxin and cytokinin are responsible for growth processes (cell division, growth and differentiation), stimulate the formation and growth of roots, enhance metabolism.
• The polysaccharide alginic acid influences the process of moisture retention in the roots, which in turn improves the growth of the root system.
• Betaine is an important activator of metabolic processes. It activates the synthesis of phospholipids of cell membranes, has the ability to increase their permeability to water, enhance the photosynthetic activity of plants and enhance resistance to biotic and abiotic stresses.
• Amino acids are involved in the biosynthesis of structural proteins, promote better absorption of nutrients, increase stress resistance of plants to abiotic stresses, fungal diseases and strengthen their immunity.
• Micro-, meso- and macroelements (N, P, K, Mg, S, Fe, Zn, B) in the organic form of the algal suspension are quickly assimilated, stimulate the primary metabolism of plants, optimize the diet in the root system.
All components of the root formation stimulator Sprintalga are in a strictly adjusted balance and mutually reinforce each other, due to which the drug is effective even at temperatures that are not optimal for the growth of the root system.
Fulvumin (Biolchim, Italy) contains in its composition 28,8% fulvic acids, as well as a complex of polysaccharides derived from seaweed. The physiological activity of fulvic acids as antioxidants (elimination of plant intoxication after pesticide treatment) and growth stimulants (due to the presence of functional groups similar to phytohormones) has been proven. In addition, fulvic acids are the most aggressive fraction of humic substances, which have a dissolving effect on mineral compounds in the soil, converting them into a form accessible to plants. Polysaccharides are a source of structural carbon, which is quickly integrated into the metabolism of seedlings, increasing their growth strength and resistance to adverse factors.
Ikar Perfectstick (IKAR, Lithuania) is a professional activator of pesticides and agrochemicals based on siloxane modified with polyester. This drug is especially effective when processing potato planting material, it enhances the effect of the drugs you use (PPP, growth stimulants, microelement complexes), this occurs due to the instant penetration of the drug used into the plant and contributes to a significant extension of its action. Now, to enhance the effect, you do not need to increase the dosage.
The addition of an activator to the working solution dramatically affects its physical properties, reducing the surface tension force. Thanks to the use of Perfectstick at a dosage of 10-12 ml per 100 liters, the solution is crushed on the nozzles into smaller drops when sprayed. Once on the treated surface, they quickly spread over it, providing a full coverage. Due to the fluidity and lipophilicity of the solution, most of the liquid is absorbed into the tubers or leaf mesophyll already three minutes after treatment, starting to work actively. Of all the adjuvants known to us, Perfectstick has perhaps the strongest penetrating properties.
The polyester, which is part of the Perfectstick activator, remains on the surface of the leaf and, when solidified, forms a thin hydrophobic film that protects the solution remaining on the surface from being washed off by precipitation, and the leaves of the plant from drying out and germination of spores of pathogenic fungi.
The use of Perfectstick at a dosage of 10 ml per ton of seeds provides not only uniform surface coverage, but also instant penetration of the solution deep into the tissues of seeds and tubers, so that the effectiveness of the use of dressings, stimulants and chemical protection measures rises to a new level. At the same time, Perfectstick in the recommended dosages does not have a depressant effect on plants and serves as a source of silicon (Si), an important trace element that increases the mechanical strength of cell walls and enhances the natural protection of plants from overheating and ultraviolet radiation.
Due to its low application rate and high efficiency, Icar Perfectstick is the ideal solution for improving the quality of systemic pesticide treatments and foliar applications.
Thus, the treatment of tubers before planting with a mixture of SPRINTALGA + FULVUMIN + IKAR Perfectstick should be recognized as one of the most effective methods of stimulating the root formation process, which contributes to a balanced nutrition of the plant organism at the juvenile stage of growth and development.
This agricultural approach provides:
- increasing the energy of germination of tubers;
- obtaining early and friendly shoots;
- rapid growth and development of a powerful root system;
- the formation of the largest number of stems;
- the optimal ratio between underground and aboveground plant biomass;
- improved absorption of water and nutrients by the root system;
- increasing the immunity and resistance of plants to diseases and stress loads.
