STOG database

Database with information on pests and diseases and different country requirements for phytopathological certificates

Information about the tool

The 'Safe Germplasm Movement' (SGM) database has been developed by CIMMYT. It allows to manage and update the information regarding import and export requirements for shipping seed of CGIAR mandate crops for all countries in the world. The information included in the database is based on the information received by Germplasm/Seed health Units managers in each center.

Most data for wheat and maize have been entered as of December 2009, and information for several other crops has been entered. Each Center has now the opportunity to populate and update the database for its mandate crop(s). It is an on-going process.

There is a help file describing the program and how it is possible to update or add data and send it to CIMMYT. It is usually possible to use the program to export and send your changes directly in an email. Please send to This email address is being protected from spambots.

Safe transfer of rice germplasm

Contributors to this page: IRRI, Seed Health Unit, Los Baños, Philippines (Patria Gonzales, Evangeline Gonzales, Carlos Huelma, Myra Almodiel, Joel Dumlao).

Rice germplasm is under the mandate of IRRI. The Africa Rice Center works on this crop in Africa.
The following pages are grouped in the following sections:

•  Import and export requirements.
•  Technical guidelines for the safe movement of germplasm and detection of relevant pathogens and pests.
•   Best practices in place at IRRI.

At IRRI, The Seed Health Unit (SHU) has been designated as the Single Gateway for all incoming and outgoing rice seeds, rice grains (dehulled, polished, milled, powdered), non seed biological materials, and soil samples to and from the International Rice Research Institute.

As a Single Gateway, SHU ensures the following:

• that seed health status of rice seeds, rice grains for destructive analysis, non seed biological materials, and soil samples coming into IRRI (IMPORTED) meets Philippine plant quarantine regulations and standards before releasing to IRRI scientists (POST ENTRY CLEARANCE);
• that seed health status of rice seeds, rice grains for destructive analysis, non seed biological materials, and soil samples going out of IRRI (EXPORTED) meets plant quarantine regulations and standards of recipient countries (PHYTOSANITARY CERTIFICATION); and
• that the intellectual property rights protocols established by IRRI in line with its agreement with the International Treaty on Plant Genetic Resources for Food and Agriculture (ITPGRFA) are complied with in all incoming and outgoing materials (rice seeds, rice grains for destructive analysis, non seed biological.

SHU approach is to conduct seed health testing on all incoming and outgoing rice seeds.  In addition, the T.T. Chang Germplasm Genebank sends samples to SHU for seed health testing prior to storage.

Seed health testing activities: 

1.   Direct Visual Examination

Seedlots are examined for the presence of seed contaminants (i.e. storage insects, sclerotia, weed seeds, soil particles, seed of other crops, other plant parts) and seed conditions (i.e. insect-damaged seeds, discolored seeds, broken grains, smutted seeds, shriveled seeds, unfilled/partially filled seeds).  Any of these seed contaminants and /or seed conditions should not be present in the seedlots. If these are observed for outgoing seedlots, the applicants will be requested to do further cleaning or will be requested to replace seeds with seeds of better quality.  For incoming seedlots, SHU staff shall clean the seedlots.  Corresponding documentation are done (seed contaminants and seed conditions are qualified and quantified).

2.   Routine Seed Health Testing

• Blotter test - conducted for the detection of seedborne fungi.  The procedure is done in accordance to the International Seed Testing Association (ISTA) rules and standards. 
• Modified Baermann Funnel Method (Sedimentation Test) - conducted for the detection and extraction of seedborne nematodes.
• Macro test - conducted for the macroscopic detection of Tilletia barclayana, kernel smut fungi of rice.

Additional declarations (if stipulated in the Import Permit of Country of Destination.)
Seed Wash Assay test using semi selective media – conducted for the detection and isolation of seedborne bacteria.

3.   Other Activities

3.1    Seed Treatment

Recommended seed treatments

Seed treatments will be based on the results of seed health tests and on the requirements of the importing country. USA and India do not require chemical and physical seed treatments except fumigation. Standard treatments given to seeds are the following:

i. Hot water treatment. Presoak seed for 3 hours in tap water followed by dipping in hot water at 52-57^oC for 15 minutes and redrying to 14% MC. The hot water treatment may be followed by slurry or dusting of fungicide (Benlate) at 0.3% by seed weight as an ASEAN standardized seed treatment (1981 July 1-23, Kuala Lumpur Meeting).

ii.  Fungicidal treatment. Slurry treatment with Benlate 50 WP, Dithane M45, or a combination of both at 0.3% formulated product by seed weight (0.3 g/100 g seeds). Retest for efficacy of fungicidal treatments will be done on samples that have abnormally high infection. Samples that do not respond to treatments will be rejected or applicants will be asked for replacements.

iii.  Insecticidal treatment. The seeds may be treated with Diazinon at 0.5 g/100 g seeds when fumigation or hot water treatment could not be done.

Fumigation.  All seeds are fumigated with Phosphine gas at 2 g/cubic meter enclosed space at 28 ^oC for 72 hours.

3.2    Crop Health Monitoring

Conducted during active growth of the crop namely: seedling stage (inspection is conducted at seedbed), maximum tillering/booting stage, flowering stage, and maturity stage, wet and dry season.

3.3    Dispatch

Seed Packages for dispatch are accompanied by required documents:  Import Permit, Phytosanitary Certificate (signed by duly authorized Plant Quarantine Officer), Standard Materials Transfer Agreement, and Plant Quarantine Seal.

All of these documents are pasted outside the package and photocopies of these documents are provided and placed inside the package in addition to the list of materials.

Import/export of rice germplasm

Contributors to this page: IRRI, Seed Health Unit, Los Banos, Philippines(Patria Gonzales, Evangeline Gonzales, Carlos Huelma, Myra Almodiel, Joel Dumlao).

Rice is a crop under the mandate of IRRI. 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 IRRI Headquarters located in Philippines have been collected from the permits granted to IRRI for exportation of rice experimental seed. It indicates specific requirements (July 2009) and the pathogens and pests that seed should be free of when it is imported to a given country. Additional information on documents required  by IRRI Seed Health Unit in compliance with the Philippine Plant Quarantine Service and IRRI’s Intellectual Property Rights for germplasm and Non-seed biological materials are provided.  The host country requirements for importing rice seed to the Philippines  are also provided. Non-seed biological materials for import are also regulated by the government of Philippines.

Please consider that:

• The information received from the same country may vary from one  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.
