(Antirrhinun spp.Linn.)

                                                      

I. Application and Amplification of General Seed Certification Standards

 

    The General Seed Certification Standards are basic and, together with the following specific standards constitute the standards for certification of Snapdragon seeds. 

 

I. Land requirements

 

    Land to be used for seed production of  Snapdragon shall be free of volunteer plants.

   

 

III. Field Inspection

 

A minimum of three inspections shall be made, the first  before flowering, the second during flowering  and the third  at maturity prior to harvesting.

V. Field Standards

 

A. General requirements

 

1. Isolation

 

Seed fields of snapdragon shall be isolated from the contaminants shown in Column 1of the table below by the distances specified in Columns 2 & 3 of the said Table


        Contaminants                                                                                   Minimum distance (meters)
