List of diseases of quarantine importance

Click here for more detailed outputs from the page on the safe movement of germplasm, on this site.

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

Bacteria

Nematodes

Fungal diseases

Options for testing procedures

Recommended methods to detect the presence of each disease:

Testing intervals/seasons

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

Recording information during health diagnosis

The following information should be recorded for each step:
