Seed of unclear origin

Important for all farmers!

Increasingly, the market is seeing seed of unclear origin, offered by unknown traders or individuals. The promises are tempting: “genuine varieties/hybrids”, “quality at a good price” and “original packaging”. The reality, however, is often different.

Low-priced big bags – in most cases, these are not breeding seed but ordinary commodity grain that has undergone minimal cleaning and is often not graded.
Questionable seed treatment – products of unclear origin are used, and sometimes there is no treatment at all.
Counterfeit paper bags – packaging that resembles the companies’ bags but has nothing to do with the original.
False information on the “blue label” – lot numbers and germination and purity figures are often invented or do not correspond to reality.

The result?
– Poor germination
– Non-uniform crops
– Risk of economically important diseases
– Loss of yield and investment
– Complete lack of traceability and no possibility of making a claim

How can you protect yourself?
Buy only from verified suppliers. Request documents of origin and laboratory analyses (a quality certificate). A low price almost always means a high risk. If in doubt, alert the representatives of the relevant breeder and the competent authorities.

Farming is an investment. Do not let counterfeit seed compromise your work.

How can you recognize unregulated seed of unclear origin?

What is being offered (claim/marketing)	What is the reality	Main risks
“Genuine seed at a low price, packed in big bags.”	In most cases, this is not breeding seed but commodity grain that has undergone only basic cleaning, often without grading.	Low or unpredictable germination; lack of varietal purity; uneven emergence; significant yield losses.
“The seed has only been repackaged, but it is genuine.”	Big bags are often used to conceal the origin; there are no processing records or quality certificates.	Origin cannot be traced; figures are invalid; there is no right to make a claim.
“It has been treated with high-quality products.”	The seed-treatment products used, if any, are of unclear, unregulated or counterfeit origin.	Insufficient protection against disease; phytotoxicity; risk of introducing pathogens; breaches of safety standards.
“Original packaging – paper bags like those used by breeding companies.”	The bags often look similar but are not genuine. They are made to imitate company packaging.	Misrepresentation; infringement of rights; use of uncertified material; absence of standard controls.
“The blue label is genuine; everything complies with the rules.”	Blue labels are very often counterfeit, with a false lot number, country of origin, varietal data and other details.	Lack of traceability; useless information; inability to prove origin to the competent authorities.
“The figures on the label are guaranteed: germination, purity and varietal purity.”	The figures are not genuine: there are no laboratory analyses, and the numbers are chosen arbitrarily to appear credible.	False information; poor performance; major losses at sowing.
“The seed is genuine but significantly cheaper.”	In reality, the seed is unselected and untested, often a mixture or commodity grain.	Major variations in overall plant development; economic damage.

What is the reality

Main risks

“Genuine seed at a low price, packed in big bags.”

In most cases, this is not breeding seed but commodity grain that has undergone only basic cleaning, often without grading.

Low or unpredictable germination; lack of varietal purity; uneven emergence; significant yield losses.

“The seed has only been repackaged, but it is genuine.”

Big bags are often used to conceal the origin; there are no processing records or quality certificates.

Origin cannot be traced; figures are invalid; there is no right to make a claim.

“It has been treated with high-quality products.”

The seed-treatment products used, if any, are of unclear, unregulated or counterfeit origin.

Insufficient protection against disease; phytotoxicity; risk of introducing pathogens; breaches of safety standards.

“Original packaging – paper bags like those used by breeding companies.”

The bags often look similar but are not genuine. They are made to imitate company packaging.

Misrepresentation; infringement of rights; use of uncertified material; absence of standard controls.

“The blue label is genuine; everything complies with the rules.”

Blue labels are very often counterfeit, with a false lot number, country of origin, varietal data and other details.

Lack of traceability; useless information; inability to prove origin to the competent authorities.

“The figures on the label are guaranteed: germination, purity and varietal purity.”

The figures are not genuine: there are no laboratory analyses, and the numbers are chosen arbitrarily to appear credible.

False information; poor performance; major losses at sowing.

“The seed is genuine but significantly cheaper.”

In reality, the seed is unselected and untested, often a mixture or commodity grain.

Major variations in overall plant development; economic damage.

The risks described above show that a lack of control and traceability in the use of unregulated seed can lead to serious agronomic, economic and environmental consequences. To highlight the differences in the quality, safety and reliability of planting material more clearly, the following table compares certified and non-certified (unregulated) seed across key indicators.

Comparison of certified and non-certified/unregulated seed:

Indicator	Certified seed	Non-certified/unregulated seed
Germination	High, laboratory certified	Unpredictable, often low
Germination energy	High	Low, delayed
Seed purity	≥ 98–99%	Low, with impurities
Varietal authenticity	100% guaranteed	Unclear or a mixture of varieties/hybrids
Seed size and grading	Graded	Not graded
Mechanical damage	Minimal	Frequent damage
Moisture	Controlled	Unknown
Foreign matter content	Strictly limited, within the standard	High
Presence of weed seeds	Controlled	Often high
Seed viability	Guaranteed	Questionable
Genetic stability	Maintained	Uncertain
Resistance to climate stress and abiotic factors	High, tested and proven	Low, unknown, random
Phytosanitary profile	Verified	Unknown
Risk of transmitting quarantine diseases	Minimal	High
Presence of pests	Controlled	Likely
Seed treatment	Professional	Absent or unprofessional
Sanitary safety	Certified	Unclear
Yield potential	High and stable	Low, unstable
Product quality	Standardized	Inconsistent
Protein/oil content	Stable	Varies
Maturity period	Predictable	Unpredictable
Uniformity at maturity	High	Low
Harvest losses	Lower	Higher

In conclusion, this analysis of the risks of using unregulated seed and the comparison with certified planting material clearly underline the key role of high-quality, controlled seed in sustainable and competitive farming. Certified seed guarantees varietal identity, germination, plant-health status and yield stability, whereas the use of unregulated seed increases the likelihood of economic losses, the spread of disease and breaches of production standards.

In this context, we recommend that farmers prioritize certified planting material purchased from licensed suppliers and request the accompanying documents of origin and quality. This approach not only reduces production risk but also creates better conditions for access to markets and various production-support mechanisms.

For their part, the competent institutions should strengthen controls over seed production and trade, improve farmers’ awareness of the risks associated with unregulated planting material, and encourage the use of certified seed through targeted policies, training and incentives. The joint efforts of producers, supervisory authorities and the seed sector are essential to ensuring safe, efficient and sustainable agricultural production in the long term.
