 Foreword  
Development of the East African Standards has been necessitated by the need for harmonizing requirements 
governing quality of products and services in the East African Community. It is envisaged that through 
harmonized standardization, trade barriers that are encountered when goods and services are exchanged 
within the Community will be removed.  
In order to achieve this objective, the Community established an East African Standards Committee mandated 
to develop and issue East African Standards.   
The Committee is composed of representatives of the National Standards Bodies in Partner States, together 
with the representatives from the private sectors and consumer organizations. Draft East African Standards 
are circ ulated to stakeholders through the National Standards Bodies in the Partner States. The comments 
received are discussed and incorporated before finalization of standards, in accordance with the procedures 
of the Community.  
East African Standards are subjec t to review, to keep pace with technological advances. Users of the East 
African Standards are therefore expected to ensure that they always have the latest versions of the standards 
they are implementing.  
The committee responsible for this document is Te chnical Committee EASC/TC 012, Seeds and propagation 
material . 
Attention is drawn to the possibility that some of the elements of this document may be subject of patent 
rights. EAC shall not be held responsible for identifying any or all such patent rights .

8 Field inspection  
8.1 The national seed certification authority shall prepare the inspections’ schedule for the inspectors, 
based on all necessary  information on the field, to ensure that the timing of inspections allows the standards in 
Table 1 or Table 2 to be properly assessed.  
8.2 The inspector shall inspect the field in accordance with OECD Seed Schemes: Guidelines for Control 
Plot Tests and F ield Inspection of Seed Crops and shall check for isolation requirements, off -types, the 
presence of noxious weeds and diseases . 
8.3 Inspections shall be done for each seed production field to confirm the field standards specified in Table 
1 or Table 2  
8.4 At the time of the first inspection, the inspector shall confirm with the grower , the previous cropping of 
the field, checking on isolation, and the proof of origin/authenti city of the variety planted by using the labels .  
8.5 For open pollinated varietie s (OPV), a minimum of two field inspections shall be done shortly before 
pollen sheds and before harvest  
8.6 In a crop producing hybrid seed, the inspector shall check the identity of the parental lines following the 
official descriptors . For fields produc ing certified seed of hybrid varieties , the first inspection  shall be 
conducted before flowering to check for isolation and rogueing; at this time the inspector shall also check the 
identity of the parental materials following the descriptors. The second a nd third inspections shall  be done  at 
the beginning and at the end of the flowering period  respectively,  to check rogueing and for male sterility in the 
female parent.   
8 © EAC 2024  – All rights reserved  
 8.7 Depending on the degree of contamination, the inspector may give instructions for of f-types and 
diseased plants to be rogued to maintain the genetic purity. In crops producing hybrid seed, rogueing is 
accepted as an option for ensuring varietal purity but plants shall be removed before pollen shedding begins. 
In the case of hybrids produc ed by male sterility, the inspector shall confirm that there are no male fertile 
plants in the female rows.  
8.8 The field inspection report shall indicate the field status and comments for any corrective actions 
required such as re -inspection to confirm th e field standards. All field inspection reports shall be provided to 
the grower and the seed enterprise after each inspection in a timely manner. The field inspection report in 
Annex B shall be signed by the inspector and may be signed by the grower or the  grower's representative . 
9 Seed sampling and laboratory standards  
9.1 The harvested seed from the field approved for certification shall be kept as an identified unit until 
processing. The identification shall include; grower’s number , field crop number, packing un it, variety name 
and seed class.  After processing, a sample shall be submitted to the laboratory for testing where  a conformed 
sample shall be given a certificate with a unique lot number for the purpose of tra ceability   
9.2 The maximum size of a  seed lot for certification purposes is 30 000 kg; lots larger than this shall be 
divided and given  separate lot numbers.  
9.3 An official seed sampler  shall draw a representative composite sample from each lot as guided by ISTA 
Rules .  
9.4 The composite sa mple shall be divided into three sub -samples, one for testing in the laboratory, one to 
be stored for reference purposes in case re -testing is necessary, and one for the post -control test.  The 
samples shall be labelled, securely sealed and shall be stored  in cool and dry conditions to prevent 
contamination and loss of germination.   
9.5 Laboratories authorized by the national seed certification authority to conduct seed testing for certification 
shall follow the methodology established in the ISTA rule s. 
9.6 The seed lots shall comply with the laboratory standards specified in Table 3 or Table 4.
