Health diagnosis and testing of banana genetic resources

Contributors to this page: Bioversity International, Belgium (Ines Van den Houwe); IITA, Nigeria (Dominique Dumet, Badara Gueye).

List of pests and diseases of quarantine importance for banana

The list below mentions some of the pests/diseases that were considered important worldwide, but many of them may or may not have relevance in specific countries. It also does not consider pests/diseases of limited relevance (e.g. only important in very few countries).

America has the greatest diversity of banana pests, followed by Africa and then Asia. Damage in Africa is often high due to the lack of natural predators of pests. Damage is greatest in the dry season or in dry areas with low or irregular rainfall.

Additional information is available on this website in the section Safe Transfer of Germplasm (STOG).

Options for testing procedures

Recommended methods to detect the presence of each pest or disease.

Viruses

Any accession officially deposited in the genebank (regardless of its origin) should have a representative sample indexed for banana viruses.

There are three Virus Indexing Centres (VIC) – CIRAD in France, QDPI in Australia or PPRI in South Africa – recognized by Bioiversity, using standard protocols as described in the FAO/IPGRI Technical Guidelines for safe Movement of Germplasm for Banana (FAO/IPGRI 1996).

Fungi

Bacteria

Weeds

Insects

Nematodes

Testing intervals/seasons

Testing before the material is introduced into the genebank or to the field is important to reduce transfer of diseases or pests.

Virus

Fungi

Bacteria

Weeds, insects and nematodes

Recording information during health diagnosis

The following information should be recorded for each health diagnosis step:

The Genebanks

The 11 CGIAR genebanks currently conserve 730,000 of cereals and grain legumes, forage crops, tree species, root and tuber crops, bananas and crop wild relatives.
