Product and Quality Specifications

These product specifications for germination of precision seeds, varietal purity of precision seeds and seed health requirements are based upon ESA recommended standards.


Technical disclaimer
This Hazera website has been constructed with the utmost care. However Hazera B.V. and/or its representants give no guarantee that the information provided, including but not limited to variety descriptions and technical advice, is complete and accurate and suitable for all purposes the user may choose.
Technical data and recommendations on this website are based on Hazera trials and general experience. A considerable part of the information given is based on Northern hemisphere or Northwest-European circumstances.
All information is only supplied to assist professional growers and users who should always take account of their local conditions or specific situations which may be different.
Hence these recommendations do not provide a guarantee of a successful crop. Hazera, therefore, accepts no responsibility or liability whatsoever for any damage or loss of profits resulting from the use of this website.


These product specifications for germination of precision seeds, varietal purity of precision seeds and seed health requirements are based upon ESA recommended standards.

These product specifications are not meant to be absolute minimum standards for delivery. If the quality tests of Hazera indicate a lower quality-level than given in these specifications, Hazera will inform prospective seed users. This communication is aimed at informing professional seed users about the quality they can expect, so they can make their own assessment and decide if these seeds meet their requirements.


Vegetable growing has become a highly specialized and intensive activity. As a result of the ever increasing demand for better quality, vegetable growers and plant raisers require an improved quality of the basic material.
The demand for specific seed forms and more information about seed quality has strongly increased to better influence emergence and required number of plants.

Seed is a natural product. The often varying environmental conditions thus influence final results. It is therefore often not possible to give detailed information about emergence and other physical seed characteristics. To meet the wishes of clients as much as possible Hazera has made up quality standards for the various seed categories.

The germination percentages mentioned are Hazera minimum required figures and made up according to ISTA methods and tolerances.


Normal Seed
In general, normal seed has not been subjected to special processes. It is sold by weight and/or by count, depending on the product. Normal seed complies with EC standards.

Precision Seed
Precision seed has been subjected to additional processes. It has a uniform size and high germination. Precision seed is sold by count.

Priming is defined as an activation of the germination process with the purpose to obtain faster or more uniform emergence after sowing. Primed seed is sold by count.

Pelleting is defined as the process of changing the seed form by covering it with a material, the main purpose being to improve uniformity of size and shape resulting in improved sowing ability. Also additional ingredients may be added. Pelleted seed is sold by count.

Film coating
Film coating is a full covering, usually pigmented layer, around the seed. The original seed form remains intact. Additional ingredients may be added. Film coating treatments that contain insecticides are normally identifiable by colour coding. Film coated seed is sold by count.

Glue coating
Glue coating is a process which fixes the applied crop protection products in an almost dust free manner to the seed. A pigment may be added.

Germination figures relate to ISTA procedures and are valid at the time of despatch.

Varietal purity
Varietal purity rate is defined as: the percentage of plants from a seed lot that meets the variety description.

In order to supply sufficiently healthy vegetable seeds and in order to meet the requirements of EU Council Directive 2002/55/EC, Hazera uses various disease risk management strategies to prevent and control seed transmitted diseases. These may include and are not limited to seed health testing programs, protected seed production, field inspections, seed treatments and other effective seed disinfection methods.

ISHI-VEG has developed the Manual of Seed Health Testing Methods, which includes state of the art seed health testing protocols. Hazera follows the ISHI-VEG recommended minimum sizes of a representative sample for seed health testing.

Information regarding the ISHI-VEG seed health test protocols and recommended minimum sample sizes can be found at:


Hazera complies, at least, with all the statutory requirements arising from legislation regarding the marketing and sales of standard seed of vegetable crops.
In order to supply the highest possible level of seed quality and service, Hazera works according to a number of quality systems designed to manage and inspect its activities. The execution of the Hazera quality assurance systems is under the control of the official Dutch inspection service for horticulture, Naktuinbouw.
Hazera’s laboratories situated in Made (NL) have been accredited according to the NAL (Naktuinbouw Accredited Laboratory) standard, to conduct routine tests for germination, genetical and physical purity and specific (seed borne) diseases.
Furthermore, Hazera is permitted by Skal, the inspection body for organic production in the Netherlands, to market organically produced seeds under the EKO quality label.
The quality systems are audited on a regular basis both internally and externally.
Hazera devotes the utmost care to the production of seeds. We can, however, not guarantee that these seeds will always match the set expectations and/or are wholly free of seed born diseases. Any liability and namely liability relating to such diseases (but not limited to these) is therefore rejected. Moreover, any damage that arises from the use of these seeds is limited to the purchase price of these seeds and the user of the seeds cannot lodge any claim with Hazera or its distributor(s) for any other (consequential) damage.
Much research at Hazera is aimed at resistances against pests and diseases. The resistance coding applied by Hazera is based on the guidelines for resistance coding established by the International Seed Federation. It is important, in general, to emphasise that the specificity of pests or pathogens may vary from time to time and from place to place, that it is dependent on environmental factors and that new biotypes of pests or new pathogenic races able to overcome resistance may emerge.
