Relikt-Re is an anti-stress biostimulant, a preparation enriched with epin, based on the hormone 24-epibrassinolide so-called epin extra. Like other preparations of the Relikt product line, it contains salts of humic and fulvic acids and a complex of chelated microelements (Mg, Fe, Mo, Zn, Cu, Co, B, Mn). The preparation also includes the hormone 24-epibrassinolide, which enhances the effect of the main active substance (the humic component) in terms of plant adaptation to stress conditions. This hormone in plants regulates the activation of auxins, cytokinins, gibberellins, abscisic acid, etc., which play a key role in physiological processes. Under stress, the synthesis of brassinosteroids slows down and decreases, which results in weaker growth and development, fruiting, and fruit quality.
Properties of the preparation
Plants naturally synthesize brassinosteroids, but under stress, their synthesis slows down and decreases, resulting in weaker development, growth, fruiting, and fruit quality.
The properties are as follows:
- activates plant hormones and triggers metabolism;
- increases plant resistance to stress conditions;
- improves crop production and yield;
- is absorbed exclusively through the leaves.
This hormone activates the plant’s own protective functions, developing its immunity against aggressive environmental conditions, i.e. against:
- frosts,
- sudden temperature changes,
- hail,
- transplanting,
- replanting,
- damage and loss of leaf mass,
- floods,
- increased soil and air humidity,
- improper fertilizer application.
It adheres well to the leaf, i.e. it is difficult to wash off.
Application
It is applied foliar and can be absorbed through all green parts and through the flower. It can also be absorbed by very young plants with a small green surface, e.g. newly developed buds, cotyledons, flowers at all stages, small fruits, etc.
The preparation can be used preventively at all stages of development. Plants treated before the onset of low temperatures are fully protected and pass without damage. The protection period is about 7 days, and if frosts persist, the treatment should be repeated.
Preventively, the application of the preparation:
- increases seed germination and germination energy,
- increases crop resistance to fungal diseases,
- activates the process of photosynthesis and leaf mass growth,
- enhances absorption of nutrients from the soil.
In addition to preventive use, the preparation can also be applied for recovery (or to accelerate recovery) in cases of stress caused by:
- hail,
- storms,
- snow damage,
- poor lighting,
- polluted soil,
- damage to or loss of leaves and aboveground mass due to bad weather,
- insect, snail, or disease attacks,
- prolonged water retention in fields,
- arrested plant growth,
- unfavorable weather conditions,
- incorrect fertilizer application, as well as in soils polluted with heavy metals and fertilizers.
Brassinosteroids in the root block the absorption (uptake) of heavy metal and radioactive ions in plants and redistribute elements in tissues, which greatly helps overcome this stress in plants that are cut several times during vegetation, such as clover, parsley, medicinal herbs, etc. The preparation aids plant regeneration and should be applied after each cut. They also stimulate the synthesis of chlorophyll a and b, as well as fructose, sucrose, and other degradable sugars necessary for growth, thus triggering and accelerating growth and recovery processes. They consolidate hormones and restore the plant to its optimal hormonal status, which restarts growth.
In short and important(!): Relikt-Re is used for the treatment of twigs, branches, leaves, flowers, and fruits (i.e., exclusively foliar). It helps plants adapt to stressful conditions. It is used immediately before shock or stress (low temperatures, frosts, storms, heavy rains, etc.).
Usage
- in the form of a water solution; use lukewarm water that has stood for at least 48 hours;
- applied exclusively foliar, i.e. by spraying branches, twigs, leaves, flowers, and fruits;
- if conditions allow (greenhouses, plastic tunnels), before foliar application the plant should be sprayed with clean water to wash off deposits (dust, etc.); after half an hour to an hour, the preparation with epin can be used;
- treat plants in the evening (6–7 p.m.);
- the absorption period of epin is about 18 hours;
- the working solution should be used within 48 hours; leftovers should be discarded.
Relikt-Re is compatible with all plant protection products except those rich in copper (which, as a rule, should not be mixed with any other substances).
In concentrated form, mixing with other preparations or agrochemicals is not allowed. Also, what is very important: Relikt-Re is incompatible with preparations that create an alkaline medium (alkaline reaction). Mixing is not possible because it cancels the effect of the preparation!

Application data
3.1. Plant species and soil type for which it is intended:
This special product is intended for all plant species, in production under protected conditions or in open fields, on different soils/substrates, especially under conditions when plant growth stimulation is required after abiotic and biotic stress, or when growing plants on heavy, clay soils and light, sandy soils and/or soils with low organic matter content.
3.2. Amount and/or concentration of application:
Total annual 1–3 L/ha per application, with a solution concentration up to 0.2%, and 1–2 L/ha per foliar application (our recommendation: 0.5–1 L/ha), with a solution concentration up to 0.5%.
3.3. Time of application in relation to plant species and soil type:
From the beginning of vegetation/transplanting until the beginning of fruit formation, or immediately before stress conditions caused by external factors, i.e. severe frosts, hail, pest attacks and/or stress caused by excess salts, acidic soil reaction, as well as stress after transplanting.
3.4. Method of application:
Through the soil, over the entire surface or locally, foliar. The mentioned methods of application can be combined in different ratios, respecting the maximum annual application amounts.
3.5. Number of treatments per year:
Several times, most often 2–4 times, or always before expected stress, at intervals of 14–21 days (our recommendation: 10–14 days), depending on the vegetation length of individual crops.
3.6. Limitation in application:
In case of mixing with other products, the mixing order is as follows: water, Relikt-Re, plant nutrition agent, plant protection agent.
Nutritional value data
5.1. Degree of nutritional value or percentage (%) increase in yield (leaf mass) or improvement of fruit quality:
The basic component of this special fertilizer consists of humic acids, which have a stimulative effect on plant growth and development through activation of microbiological processes and stimulation of microbial biomass activity.
There are also data on the biostimulant effect of humic acids, which is reflected in nutrient uptake and overcoming abiotic stress.
Foliar application of humic acids is associated with the stimulation of photosynthesis processes and plant growth and development, so foliar application of the product is particularly effective under conditions prior to stress caused by abiotic and biotic factors.
In addition to humic acids, this product also contains the microelement boron, which is essential in numerous metabolic processes, such as photosynthesis, chlorophyll synthesis, uracil base (RNA base) synthesis, respiration, protein synthesis, activation of numerous enzymes, etc. Therefore, optimal plant nutrition with boron affects the yield level and quality of obtained products, primarily in terms of carbohydrate content. Boron also contributes to the stimulation of stamen growth, thereby promoting fertilization, which directly affects yield. In root crops, optimal plant nutrition with boron reduces the possibility of root rot. These effects of boron are particularly pronounced with foliar application of this product.
