Tridge summary

A new strain of the fungus Plenodomus biglobosus, causing phomosis in plants, has been identified in the UK and could pose a significant threat to rapeseed crops. The fungus, previously only found on wasabi plants, has now also been identified in the West Midlands and confirmed to affect rapeseed and cabbage through DNA analysis. This marks the first time the disease has been found on vegetables in Europe. More monitoring is needed to understand the distribution of this pathogen in modern pathogen populations in the British Isles and continental Europe.

In the UK, a new species of fungus, Plenodomus biglobosus, which is causing phomosis in plants, could pose a serious threat to the rapeseed crop. A new variant of phomosis has been discovered for the first time in Europe, Agropages.com reports. A variant of Plenodomus biglobosus "canadensis" was discovered last spring on wasabi plants, marking the first time the disease has been found on vegetables. Another variant of the fungus, P. biglobosus "brassicae", has also been identified in the West Midlands. DNA analysis of crops taken from infected plants confirmed the pathogen, said Rothamsted plant pathologist Dr.Kevin King: “Then research in greenhouses showed that both variants can cause disease not only in wasabi, but also in rapeseed and cabbage. To date, phomosis has been found in brassica species in Australia, Canada, China, Mexico, and the United States. For the first time, a dangerous strain has been identified in two different regions of the UK. Scientists have found that ...
