CROPS STRESS MANAGEMENT IS THE PROFICIENCY OF AGRONOMIST
Currently there are plenty of effective solutions to almost every biological issue that causes crop losses. We have many tools to improve soil fertility, plants nutrition and their protection against insects and diseases, weed’s control, etc. However, no agrarian is insured against crop losses caused by stressors. The crops stress management is an important part of providing wealthy yield, and is an indicator of agronomist’s proficiency.
Number of studies has confirmed that yield losses due to stressor are 3- or 4-times fold compared to other factors.
Stress types and plants reaction to stress are explained in the article
“Minimize stress - save the harvest”The most crop damage is caused by climatic stress, that could reduce the yield up to 70%, edaphic stressors up to 40%, and anthropogenic up to 30%.
Plants have several mechanisms to defend against plant stress, they are:
- Accumulating amino acids and soluble sugars in cells
- Maintaining a concentration of antioxidants
- Promoting saturation of fatty acids in cell membranes
- Developing waxy layers around roots that prevent water loss
- Ensuring healthy enzyme levels
THE INNOVATIVE PROGRAM “STOPSTRESS” IS A PERFECT COMBINATION OF MICROBIAL PREPARATIONS THAT HELPS PLANTS TO AVOID STRESSORS.
The small stresses plants can overcome - in a sense, they contribute to increasing of the organism's resistance and better adaptation to changes in environmental conditions. However, when the influence of stress factors has passed the threshold value, it can even lead to plants' death.
So, if agronomist does not help the plants in time, avoiding crop losses will not be possible.
The application of biostimulants can help plants to avoid stress or minimize its impact.
To increase crop resistance to stress factors, prevent harmful effects of stress and stimulate plants recovering after stressors, we recommend to apply the innovative program “STOP STRESS” in BTU-CENTRE.
“STOP STRESS” is based on the complex application of three microbial preparations ORGANIC-BALANCE®, AZOTOHELP® and LIPOSAM® adhesive.

Photo #1 The innovative program with microbial preparations – “STOP STRESS”.
The main advantages of the innovative program "STOP STRESS":
- Increases plants resistance to stressors: biotic, anthropogenic, climatic, edaphic
- Reduces the toxicity of chemical pesticides
- Accelerates regeneration of growth and development of winter crops after winter
Recommendations for application:
- Previously to stress factors to ensure plant tolerance to stress
- Simultaneously with stress factors on the plant to reduce the stress load
- After a stress factor to restore growth processes
- For foliar feeding of crops
WHY APPLYING BIOLOGICAL ANTI-STRESS PRODUCTS IS THE BEST OPTION?
First of all, the plants physiology mechanisms allow to accumulate different amino acids and soluble sugars in cells to resist against various stresses. In addition to the bacteria, the preparation (liquid form) also contains their life products. Therefore, immediately after application on the plants, the natural process of absorption of these metabolites (phytohormones, vitamins, amino acids) begins.
As we talk about living organisms, the amino acids which are roduced by living organisms (eg. bacteria) will be more effective for plants in stress period than synthetic analog. In our preparations, we use bacteria that interact naturally with plants in the ecosystem.
“STOP STRESS” is helpful for all kinds of crops, including cereals, vegetables, fruits and berries, as well as technical and decorative plants.
As practice shows that the effectiveness of the application “STOP STRESS” is more than 92%. BTU-CENTER has conducted over 45 trials with STOP STRESS on different crops.

STOP STRESS. THE POWER OF EACH BIOPREPARATION IN COUNTERACTING STRESS
ORGANIC-BALANCE® is a biostimulant, a basic component of the "STOP STRESS" program. It ensures the balanced nutrition of plants and increases their resistance to stresses. The composition of microbial preparation includes vital microorganisms: Bacillus subtilis, Lactobacillus, Paenibacillus polymyxa, Azotobacter chroococcum, Enterococcus.The total titer of the preparation is over 1×109 CFU/ml. Effective application rates – 0,2-0,5 l/ha (vegetation); 0,15-6 l/t (seed treatment).
ORGANIC-BALANCE® performs two main functions: nutrition and immunity improvement.

Scientist and field trials mention that Azotobacter chroococcum colonies are able to fix and process into available for plants form an average 20 kg/ha of nitrogen, with a recorded maximum of 60 kg/ha. The amount of additional nitrogen that AZOTOHELP can provide depends on the specific field’s conditions, like type of soil, pH, level of moisture, level of soil available phosphorus and potassium and etc.
In addition, by producing nitrogen compounds, bacteria in the composition of AZOTOHELP release plant hormones, which enhance plants’ growth.
We have conducted over 370 researches with AZOTOHELP® in 12 countries of Europe. More than 87% of farmers have positive results, where income covers application costs. The average additional income per ha is more than 170 $/ha.
LIPOSAM® is a biological adhesive agent that prevents the washing of nutrients, plant protection products and biostimulants from the surface and enhances plant resistance to stress factors. LIPOSAM® is an ecologically pure product based on a complex of natural exooligopolysaccharides. The microbial preparation forms a protective elastic net that softly covers the plant organs, retains moisture, and provides good growth, breathing and photosynthesis processes.
Competitive advantages of the LIPOSAM®:
- fixes the biopreparations and other plant protection and nutrition preparations on the planting material;
- forms a protective elastic net that retains moisture;
- provides high efficiency of soil herbicides under adverse weather conditions;
- operates in a wide range of temperatures;
- sorbent-carrier, acts as antistressant and increases the drought tolerance of plants.
- biosticking agent-carrier, which is compatible in tank mixtures with the most active substances
LIPOSAM® contains biopolymer of bacterial origin and is allowed for organic farming.
We have practiced confirmed efficiency of LIPOSAM® in 12 countries worldwide, both in organic farming and integrated pest management (IPM). Annually more than 2 million hectares of farmland are treated with LIPOSAM®. The efficiency of the preparation's application, which results in increased yields and, consequently, profits, was noted by 86% of farmers.
Thus, microorganisms in ORGANIC-BALANCE® and AZOTOHELP® provide the plant with amino acids, which participate in metabolism, serve as a building material for cell formation (development and growth) and perform many other vital functions in plant organisms. Proteins are synthesized from amino acids. And the plant's resistance to stress conditions and overcoming their consequences depends on its qualitative and quantitative composition in plants. Bacteria contained in ORGANIC-BALANCE ® also produce phytohormones and vitamins. Furthermore, LIPOSAM® will provide better biostimulants' penetration and prolong the retention time. Besides, this biopreparation will reduce the stress from the harmful effects of pesticides due to the good absorption capacity of polymers.
All preparations included in the program have a mild effect and do not lead to overdose. The complex of preparations is applied together with herbicide application – in advance or the initial stages of stress.

The stress caused by herbicide application on field crops is one of several stresses that could be caused by human influence. The aim of herbicide application is to control weeds spread and development. However, at the same time, the field crops like sunflower can be suppressed in development by harmful aftereffect of these pesticides.
The level of negative aftereffect depends on specific conditions: correct application rate, plants stage, temperature, application time, concentration of active substances, etc. Knowing this, it is important to follow the manufacturer's application recommendation. Generally, after application of herbicide, the plants need nearly one-two weeks to recover its development processes.
Moreover, when field crops are highly damaged by chemical herbicide (ex. leaves burns), it is necessary to apply biostimulants to prevent yield loses. The innovative program “STOP STRESS” effectively manage the herbicide stresses, let’s study deeply on examples.

And of course, we should not forget about the effectiveness of the innovative program “STOP STRESS” in frosts and temperature fluctuations.
THE FEEDBACK OF VOLODYMYR FANTUKH, DIRECTOR OF CROP PRODUCTION DEPARTMENT “AGRODIM” LTD, CHERNIGIVE REGION, UKRAINE.
Winter wheat has gotten the second life. In 2017 the frosts caused a significant damage of plants. “It was 30th of April on the calendar, in a month it’s already necessary to harvest, however there was a trouble in the field: wheat was standing with turned yellow leaves due to freezing. We decided to apply BTU-CENTER innovative program “STOP STRESS” - the perfect combination of microbial preparation in stress management. The application of ORGANIK-BALANCE®, AZOTOHELP®, LIPOSAM® has given a positive impact on plant development - the leaves were full of dark green color, and the plants were fast recovered, in front of our very eyes,” reminds Volodymyr Fantukh. As a result, the company decided to apply the “STOP STRESS” program for growing corn, sunflower and rape. Hence, company got 6,6- 6,9 t/ha of wheat, 10 t/ha of corn - for agricultural year with unfavorable weather it is very good result.

The innovative program “STOP STRESS” is an effective solution in crops stress management, it can be applied in advance, before the action of a stress factor to ensure the stability of plants or after the action of a stressor to restore growth processes. During stress plants growth and development are inhibited, the absorption of nutrients deteriorates, the products of photosynthesis cease to enter the root system. Plants expend a huge amount of energy to survive and as a result, under prolonged stress, they have almost no strength to form a crop. Therefore, after the end of the stress factors, it is very important to apply “STOP STRESS” to help them recover faster and speed up metabolic processes.
