Dr. Megan Dewdney, CREC's new
Assistant Professor of Plant Pathology
and Extension Specialist, recently
Dewdney was born and raised in
British Columbia's Okanagan Valley,
in the heart of the apple production
area of western Canada.
She received her bachelor's degree
from the University of British Columbia,
with a majorin PlantSciencewhere she
became interested in plant pathology.
The summers of her undergraduate
degree were spent collecting data
in the apple replant program for the
Okanagan Valley Tree Fruit Authority.
She then attended McGill University
to complete a master's degree in
Plant Science. Her project was to
assess the relative susceptibility of
apple cultivars to Venturia inaequalis,
the apple scab pathogen. This
project was done in conjunction with
Agriculture and Agri-Food Canada in
St-Jean-sur-Richelieu, PQ and was
supervised by Drs. Timothy Paulitz
and Odile Carisse.
She completed her Ph.D. work
at Cornell University under the
supervision of Dr. Herb Aldwinckle.
Her project first assessed the forecast
accuracy of two blossom blight
forecasters. Stemming from that initial
program, she concentrated her focus
on the population dynamics of Erwinia
amylovora, the bacterium responsible
for fire blight. She graduated from
Cornell University in January.
Dewdney's job here is a 70 percent
extension and 30 percent research
appointment. She is also a statewide
extension specialist for Citrus
Pathology. Her research will focus on

Dr. Megan Dewdney

foliar/fungal and bacterial diseases of
citrus. Her extension appointment will
entail leading the statewide effort to
educate members ofthe citrus industry
on research and management efforts
on citrus greening and citrus canker.
She is also responsible for information
about fungal foliar pathogens.
Her goals include keeping the citrus
industry viable in Florida, especially
with the threat of canker and
In her spare time, she likes to bike
ride, read, keep abreast of current
events, garden, snow ski, and
snowshoe, as well as other winter

Dr. Dewdney may be reached

The first international symposium on 'Application of
Precision Agriculture for Fruits and Vegetables' was
held from Jan. 6-9, in Orlando. The co-conveners
were Drs. Reza Ehsani and L. Gene Albrigo of
UF/IFAS CREC. Ninety-nine people participated with
representation from 17 countries.
The meeting was sponsored by the International
Society for Horticultural Sciences, the International
Society of Citriculture, the American Society of
Agricultural and Biological Engineers, and the Citrus
Research and Education Foundation.
Subjects covered at the meeting included: remote
sensing, sensing and control systems, site specific
management, automation and robotics, as well as
economic, quality, and environmental issues. Oral
(43) and poster (19) presentations were made on
these subjects. Invited speakers and their topics

included: Pol Coppin (Katholieke Universiteit Leuven,
Belgium), Andre Torre-Neto (EMBRAPA, Sao Carlos,
Brazil), Instrumented Citrus production; Simon
Blackmore(UniBots Limited,Engla nd),ASpecification
for an Autonomous Crop Production mechanization
System; John Reid (Moline Technology Innovation
Center, Moline, Illinois), Service Robotics for Fruit
and Vegetable Automation; Lawrence Gaultney
(DuPont Agricultural Products, Maryland), Economic
and Environmental Benefits of Precision Agriculture
in Fruit and Vegetable Production.
Following the two days of oral and poster sessions,
a tour was provided of a citrus processing facility;
a modern, highly-automated citrus nursery; an
automated, remote controlled irrigation system; and
mechanical harvesting of citrus. The tour group also
visited the Citrus Research and Education Center.
