What types of tests does the laboratory perform?

To diagnose diseases in grain and seed material, MicroBio Laba performs comprehensive phytopathological testing using a range of complementary methods.

Macroscopic examination method

Macroscopic examination method — used to detect smut balls, ergot and other fungal sclerotia, and wheat nematode galls;

Centrifugation and microscopic examination method

Centrifugation followed by microscopic examination is used to assess the contamination of grain and seed samples with pathogens present on the surface as spores or mycelium;

Biological testing method

The biological method involves examining seeds in a moist chamber, in filter paper rolls, on sand or on nutrient media to detect external and internal pathogen infection in seeds and seedlings.

Frequently asked questions

Seed material quality is influenced by crop cultivation practices, soil and climatic conditions, regional factors and the types of fertilisers used.

Grain testing can be requested whenever required. It is most commonly carried out before export or before the grain is placed into storage.

Samples must be collected and submitted in accordance with the laboratory’s sampling guidelines. For further details, please contact MicroBio Laba by phone.

Test reports are provided to the client within the timeframe confirmed by the manager. The delivery method is agreed during the consultation.

Grain and seed testing

Seed quality is an important indicator for agricultural producers. It affects not only yield volume and commercial characteristics, but also the company’s profitability. For this reason, producers prefer to use only high-quality seed material that meets the established requirements for sowing.

Seed testing carried out by MicroBio Laba helps assess its quality. We perform different types of testing using high-precision equipment and modern technologies. Our range of services also includes grain quality testing. Our agricultural laboratory helps determine moisture content, impurities, gluten content and other parameters.

Why is grain testing recommended?

Confirming the quality of seed material through laboratory testing is one of the key factors in building a positive reputation for producers and suppliers of such products. The availability of a test report increases customer confidence, supporting stable business performance and company development.

However, seed quality testing of agricultural crops is also important in other cases. This service can be requested by agricultural producers who want to verify that their seed material is of high quality. Grain quality testing should also be considered separately. It is required to check the properties of raw material before export or before placing it into storage.

Which parameters can seed and grain testing determine?

During the testing process, laboratory specialists can carry out different types of examinations. These are aimed at determining the falling number, moisture content, germination capacity and thousand seed weight. In addition, testing can identify:

  • viability indicators;
  • test weight;
  • oil content;
  • the presence of internal and external infections, including bacterial infections;
  • infection with diseases and fungi;
  • the presence of weed and grain impurities.

Seed material testing makes it possible to determine seed germination energy. In the case of grain testing, general parameters can be determined, including moisture content, infection and impurity levels. In addition, laboratory testing can identify protein mass fraction, gluten quality and quantity, falling number, chemical composition, viability, microflora and other characteristics.

Types of seed testing

Seed testing includes examinations that make it possible to determine compliance with established standards and requirements, as well as a number of important properties. The following methods are used for this purpose:

  • Washing with centrifugation. Laboratory specialists use this method to detect surface bacterial contamination.
  • External examination. This is used to detect external signs of disease infection in seed material, including deformation, underdevelopment, shrivelling, dullness and other visible changes.
  • Moist chamber method. This is another method used to detect bacteria. Dry Petri dishes and other laboratory tools are used during the process.
  • Germination in test tubes. Sand and other materials are used as a substrate. This method is used to identify bacterioses, including the pathogen and the degree of infection.

Grain quality testing involves physicochemical testing and organoleptic examination. During testing, it is possible to determine the levels of gluten, ash, protein and other substances.

How is grain quality testing carried out?

Laboratory specialists perform testing in several stages. Special equipment and tools are used at each stage. The client is required to provide samples for testing and specify the request.

To order seed testing, simply contact the laboratory. You can submit a request on the website or contact us by phone. Once the details, including the cost, have been agreed, the samples should be submitted in accordance with the laboratory specialists’ recommendations. The manager will inform you of the date when the results will be ready.

What is the cost of seed testing?

The price of services is specified in the price list. However, additional factors may affect the final cost. These include the number of samples and the method of sample delivery. If the client visits the laboratory in person and requests a large number of tests, the cost may be reduced. To find out the exact price, please contact the laboratory and describe your request.

How can the results be used?

Test reports contain valuable information for agricultural producers and suppliers of seed material. They make it possible to:

  • plan a seed treatment system;
  • verify quality;
  • confirm compliance with the declared certificates.

In addition, test results help calculate seeding rates, both by quantity and by weight, and optimise the use of seed treatment products.

Why do clients trust us?

Laboratory testing of grain and seed material carried out by MicroBio Laba provides complete, accurate and detailed information. This is made possible by the professionalism of our specialists and the use of modern equipment and reagents.

An important factor is accreditation to the international standard DSTU ISO/IEC 17025 in the field of microbiological and physicochemical testing. This helps ensure reliable results. To order seed testing or chemical analysis of grain in the laboratory, simply contact our managers in the most convenient way.
