Video: Phytophthora - Stop the spread (2012)

A group of over 20 organisations from the public sector, charities and the private sector have got together to produce two videos to help tackle the threat posed to our plant nurseries, gardens, woodlands and countryside from two devastating Phytophthora pathogens, Phytophthora ramorum and Phytophthora kernoviae.

This film is aimed more at professionals who work in environments where the diseases may be present or that could easily be contaminated. It describes the diseases in more detail and offers advice on appropriate biosecurity measures to help prevent the spread. It may also appeal to those studying life sciences at college or university.

'Unprecedented threat' for UK trees - BBC News

'Unprecedented threat' for UK trees - BBC News | forest pathology | Scoop.it

BBC News has posted an article about the recent pest introductions into the UK. It is stressed that the UK trees are facing an "unprecedented level of threat" from non-native pests and diseases.

Impacts and prevention strategies are presented (without forgetting the role of EPPO and the IPPC!).

YouTube: Phytophthora plurivora zoospores attracted to Beech root exudates (2012)

During my PhD I have worked with Phytophthora species, which are very aggressive microorganisms that infect plants, causing huge economic and environmental losses. Commonly Phytophthora species spread and infect plants via zoospores, a motile asexual structure that uses a flagelum for locomotion. The zoospores can "sense" and swim towards plants signals starting an infection.


In this video I tested the attraction of P. plurivora zoospores to root exudates of European beech. The major decline of beech trees in forests worldwide has been associated with P. plurivora-caused disease. In the video you see a microscopy view of two pipette tips filled with water or root exudates. The pipettes were embedded in a zoospores suspension. Clearly the zoospores were more attracted to the root exudates than water.

New Phytol. (2012): Biogeographical patterns and determinants of invasion by forest pathogens in Europe

New Phytol. (2012): Biogeographical patterns and determinants of invasion by forest pathogens in Europe | forest pathology | Scoop.it

A large database of invasive forest pathogens (IFPs) was developed to investigate the patterns and determinants of invasion in Europe. Detailed taxonomic and biological information on the invasive species was combined with country-specific data on land use, climate, and the time since invasion to identify the determinants of invasiveness, and to differentiate the class of environments which share territorial and climate features associated with a susceptibility to invasion. IFPs increased exponentially in the last four decades. Until 1919, IFPs already present moved across Europe. Then, new IFPs were introduced mainly from North America, and recently from Asia. Hybrid pathogens also appeared. Countries with a wider range of environments, higher human impact or international trade hosted more IFPs. Rainfall influenced the diffusion rates. Environmental conditions of the new and original ranges and systematic and ecological attributes affected invasiveness. Further spread of established IFPs is expected in countries that have experienced commercial isolation in the recent past. Densely populated countries with high environmental diversity may be the weakest links in attempts to prevent new arrivals. Tight coordination of actions against new arrivals is needed. Eradication seems impossible, and prevention seems the only reliable measure, although this will be difficult in the face of global mobility.
