# Deena Errampalli

Deena Errampalli is a Canadian plant pathologist who is internationally known for her work on postharvest pathology of temperate tree fruits. She has conducted research in India, the USA and Canada and her work has resulted in new and innovative disease management strategies to improve plant health through Integrated Pest Management. Errampalli was a researcher at Agriculture and Agri-Food Canada Vineland, a satellite station of the London Research and Developmnent Centre (2000-2018) Errampalli was also the Test-Site-Manager for Agriculture and Agri-Food Canada Minor Use Pesticide Program at Vineland Station where she managed trials for insect pests, diseases and weed control on minor use crops. She is also an award-winning fine-art painter, printmaker, and photographer whose work has been displayed in Canada, Italy, Poland, South Africa, USA, and India.

## Early life and education

Errampalli was born in 1958 in South India. Her mother, Mary Bharathi Kondaveti was a high school teacher, and her father, Stephen Devadatham Errampalli was an agronomist and later an assistant director of agriculture in Andhra Pradesh.

Her Ph.D. thesis (1990) title was Characterization of Aster Yellows in Oklahoma.

## Career

In the 1980s, she worked on the development of viral disease resistant germplasm of pulses (pigeonpea and chickpea) at the International Crops Research Institute for the Semi-Arid Tropics in Patancheru, India.
After moving to Canada in 1992, she completed two post doctoral positions, first one at the University of Toronto Mississauga and the second at the School of Environmental Sciences, University of Guelph.
She joined Agriculture and Agri-Food Canada as a research scientist in 1998 at the Charlottetown Research and Development Centre, Prince Edward Island, and conducted research on soil borne diseases of potatoes. In 2000 she moved to their London Research and Development Centre at Vineland, Ontario, Canada and has conducted research on pathology of tree fruits and vegetables, with a focus on postharvest pathology of tree fruits until 2018. The goal of her research was to develop integrated pest management strategies for postharvest temperate tree fruits, grape, and potato diseases with cultural, biological and/or chemical control methods in Canada.
Errampalli’s research projects at Agriculture and Agri-Food Canada were development of management strategies for replant disease in ginseng production in Ontario; new biological control products for postharvest diseases of pome fruit; Development of organic control strategies for apple scab; and Management of black knot in plums.
In 2006, Errampalli was appointed as the test site manager for the Agriculture and Agri-Food Canada Minor Use Pesticides Program, Vineland site. The program conducts field research and creates residue and /or efficacy data on tree fruits, small fruit and vegetable crops to support the regulatory registration submissions for fungicides, insecticides and herbicides.
She has published 35 refereed journal publications, 6 book chapters, over 200 Pest Management Research Reports, 60 confidential reports and 15 articles in popular grower magazines and newsletters and has made over 200 presentations at regional, national and international scientific conferences.
