Import/export of cowpea germplasm

Contributors to this section: IITA, Nigeria (M. Ayodele, L. Kumar).

Cowpea is a crop under the mandate of IITA. It is very important to remember that an International Phytosanitary Certificate is always required for any plant germplasm exchange.

The requirements of countries that request and receive seed from IITA Headquarters located in Nigeria have been collected from the permits granted to IITA for exportation of cowpea experimental seed. It indicates specific requirements and the pathogens and pest that seed should be free of when it is imported to a given country.

Please consider that:

  • The information received from the same country may vary from a permit to another; therefore the latest has been considered the valid one.
  • It is always advisable before sending a shipment to contact the consignee in the recipient country to confirm the information reported in this table.

Seed Health Tests and Procedures

Protocols developed for the detection and identification of plant pathogens in the germplasm unit.
 

The general procedure for testing seeds and plant vegetative parts for the presence of pathogens is presented in this diagram below. Except in some specific cases requiring some special media or modified media for culturing
