Quarantine plant pathogens: hidden links

Non-obvious links between quarantine plant viruses and bacteria, surfaced from EPPO data. Pathogen pairs that share a vector (insect or nematode), ranked by vector specificity, host botanical distance and link confidence.

264 candidate pairs out of 154 A1 · 76 A2 · 34 RNQP. 152 with confirmed (K-K) vector transmission, 112 potential.

Data is limited to EPPO coverage. A number of quarantine viruses (viroids, nepoviruses spread through planting material) have no recorded vector and are not shown here. Links flagged "potential" are hypothetical and require expert review.
