Evaluating the mycoherbicide potential of a leaf-spot pathogen against Japanese knotweed
Japanese knotweed is a highly invasive weed that impacts severely on native biodiversity and local infrastructure in its introduced range. Whilst chemicals are currently used to control the weed, this approach is costly and unsustainable. Biological control is an alternative method. The damaging leaf-spot fungus, Mycosphaerella polygoni-cuspidati, which attacks the…
New monitoring and reporting framework aims to better protect World Heritage Sites from invasive alien species
A team of international scientists have devised a new monitoring and reporting framework to help protect World Heritage Sites from almost 300 different invasive alien species globally including, rats (Rattus spp.), cats (Felis catus), lantana (Lantana camara) and Argentine ants (Linepithema humile). Lead author Dr Ross Shackleton joined invasive species…
Study shows low risk of non-target attack of European plant species by hay fever-causing ragweed ‘bug’
A team of international scientists believe that the accidentally introduced leaf beetle Ophraella communa poses a low risk to native European plant species other than the invasive hay fever-causing ragweed species (like common ragweed, Ambrosia artemisiifolia) which it does attack. PhD student Benno Augustinus, who is being co-supervised by CABI’s…

Identifying the origin of yellow floating heart, Nymphoides peltata
Yellow floating heart, Nymphoides peltata, was introduced in North America in the late 19th century as an ornamental plant. Since its introduction, it has steadily spread and been repeatedly introduced across the United States and parts of Canada. Where introduced, yellow floating heart can outcompete native vegetation and phytoplankton, and…
