Coming Events
Problems in Cassava in
SE Asia
Readers of the ISPP Newsletter will have noted the
major problems for cassava crops in Africa, but now comes an urgent alert
about pest and disease outbreaks in cassava in south-east Asia. Attention
was drawn to the alert issued by CIAT in this region by a ProMed-mail post
on 22 January 2010.....
http://www.promedmail.org.
Cassava production in Thailand
and Vietnam is being severely affected and CIAT is investigating reports
that crops in Cambodia, Laos and the Philippines have also been affected.
China, Myanmar and Indonesia may become affected.
Thai crops were found to be
infested by a large number of mealy bugs, tropical whiteflies and red
mites. Cassava bacterial blight (CBB) caused by Xanthomonas manihotis and
brown leaf spot disease caused by Mycosphaerella henningsii were also
widespread. These problems had not been severe previously in Thailand, but
they may have been exacerbated by higher than usual rainfall. Many farmers
have abandoned their crops, and widespread economic and social
implications are expected in a country that accounts for three-quarters of
the world’s cassava exports.
CIAT reports that the main problems in neighbouring
Vietnam were not the pests but diseases, particularly CBB and also the new
problem to farmers there of witches’ broom phytoplasma.
Urgent preliminary guidelines to
tackle the outbreaks include strict quarantine regulations on the movement
of cassava material and of related species like Jatropha. Establishing an
effective surveillance and monitoring system is essential. Developing an
Integrated Pest and Disease Management Strategy based primarily on
biological control will become a priority. Breeding of cassava cultivars
with better pest and disease resistance will also become a priority.
Video on the Life Cycle of
Rust Fungi
A new item on the American Phytopathological
Society’s Plant Diseases’ Channel at
http://bit.ly/aKb9kv
is a video on the life cycle of rust fungi. It was taken from “Leaf Rust
and Other Rusts of Cereals”, one of the teaching videos available in
Volume 2 in “The Biology of Fungal Pathogens DVD series”.
The video on the rust fungi is
also included in “50 Video Clips on Fungal Diseases of Cereals DVD” which
is a 2008 product of APS Press and contains short movie clips taken from
eight full-length videos in the first four volumes of the DVD series “The
Biology of Fungal Pathogens” edited by Professor Dr Joseph-Alexander
Verreet and Dr Holger Klink of the Christian-Albrechts University, Kiel,
Germany.
A fifth volume in the DVD series has recently become
available in 2009 from APS Press and it has two new videos “Pythium Root
Rot of Cereals” and “Rhizoctonia Root Rot of Cereals”.
For full information about the
DVDs see:

Pilot Knob Road, Saint Paul, MN 55121, USA.
Fusarium Events
Two educational events about Fusarium will take place
during this year. An international workshop will be held in Argentina in
March 2010, and a European seminar will occur in Poland in September 2010,
as detailed in “Coming Events”.
The workshop is at Universidad Nacional de Río
Cuarto, Argentina. It will be taught by Sofia Chulze, John Leslie, David
Geiser, Ralf Kristensen, Antonio Logrieco, Ludwig Pfenning and Brett
Summerell. Participants will be introduced to standard morphological,
genetic and molecular biological techniques used to identify and
characterize strains of Fusarium. Participants will learn to use
morphological characters to identify the most common Fusarium species, how
to make tests for vegetative compatibility groups (VCGs), how to extract
and PCR amplify DNA, and how to analyze DNA and sequences. More than half
of the time will be spent in the laboratory working with standard strains.
The seminar is at the Plant
Breeding and Acclimatization Institute (IHAR), Radzikow, near Warsaw,
Poland. The International Scientific Committee is Edward Arseniuk –
chairman, Jerzy Chełkowski, Tomohiro Ban, Etienne Duveiller, Jeannie
Gilbert, Antonio Logrieco, Zheng-Qiang Ma, Hongxiang Ma, Adriano Marocco,
Akos Mesterhazy, Thomas Miedaner, Paul Nicholson, Juliusz Perkowski and
Cees Waalwijk. All scientists, policy makers and industry representatives
who are engaged in issues related to mycotoxin reduction in food and feed
chains are invited. The problem is global and the seminar will be an
occasion for discussion within the community of Fusarium researchers about
recent advances and progress.
Aphid-attracting Signals Induced by Plant Virus Infection
Infection by cucumber mosaic
virus causes plants to emit a signal that attracts aphids which land
briefly picking up the virus before carrying it to other plants.
This is according to work by a
group lead by Mark Mescher, a chemical ecologist at Pennsylvania State
University who specialises in chemical cues used by plants, and reported
as Mauck K E, DeMoraes C M and Mescher M C (2010) Deceptive chemical
signals induced by a plant virus attract insect vectors to inferior hosts.
Proceedings of the National Academy of Sciences 107 (5). Attention was
drawn to the finding through an alert from PestNet
www.pestnet.org.
New Dates - Mediterranean
Phytopathological Union Congress
The organisers of this MPU Congress
in Rome have urgently advised of a change of dates to 20-25 June 2010.
See: “Coming Events”.
Circumstances beyond their control have forced the changes. The Congress
will now start on Sunday 20 June with registration followed by scientific
sessions on four days and ending with a full-day excursion in Rome and its
surrounds on Friday 25 June 2010.

Retirement of John Mansfield
John W Mansfield retired in
January 2010. John had been at Wye College, University of London, UK, but
recently was transferred to Imperial College after Wye College near
Ashford in Kent was taken over by Imperial College at South Kensington
also within the University of London.
John did his PhD in plant pathology at Imperial
College. He worked on interactions between Botrytis spp. and broad bean
leaves (Vicia faba) and particularly on the role of phytoalexins. He then
moved to an academic post at Stirling University in Scotland, where one of
his many ingenious papers (1974 Nature 252, 316-317) revealed the cellular
sites of phytoalexin production around the points of infection. At
Stirling, he also supervised the work of several PhD students who helped
to make him to make important progress on this and other infections of
plants by Botrytis spp.. He later moved to the Biology Department at Wye
College, where he remained for many years and was promoted to the rank of
Professor. He has published prolifically with his numerous associates on
several plant-pathogen interactions, including downy mildews. He is
well-known internationally for his research which in recent years has been
on interactions between Pseudomonas spp. and plants, and particularly on
the role of effectors. See his overview of this topic in Molecular Plant
Pathology 10 721-734 (November 2009). He was co-Chair with Pierre de Wit
of a major session in these research areas at the International Congress
for Plant Pathology in Turin in 2008.
In retirement, John plans to continue with
publication from Imperial College and he retains a web-site there, with
his career and publications at
http://www3.imperial.ac.uk/people/j.mansfield.
Mycotoxicological Risks in
Mediterranean Countries
An international
workshop will take place in Cairo, Egypt, in October 2010 and will focus
on co-operation among Mediterranean countries (see “Coming Events”).
It will have an overview on
the occurrence of mycotoxins and toxigenic fungi in the region. Prevention
and control of mycotoxins in food and feed chains and mycotoxins of public
and animal health significance will be other themes.
