Yield reductions of pea caused by Pseudomonas syringae pv. pisi

Experiments were carried out in the United Kingdom (GB) to assess the yield reduction of single pea plants infected by Pseudomonas syringae pv. pisi (EPPO A2 quarantine pest). It was found that the yield was reduced by 24, 47 or 71% following an inoculation with pea bacterial blight during reproductive, vegetative or both reproductive and vegetative growth stages, respectively. Yield reductions were expressed as reduced numbers per seeds per pod and a reduced number of pods per plant.
