Profile: 

Dr. Dhanya M.K attained her Ph.D degree in Plant Pathology from the Kerala Agricultural University.. Her notable works include management of major diseases in spices using bio agents and less toxic fungicides, studies on the compatibility of bio agents with pesticides, correlation between weather parameters and pest and disease development in spices, biochemical defence mechanisms in disease tolerant plants, drought mitigation in spice crops using beneficial microbes and genetic variation and qualitative aspects of major spices. She identified three pathogenic fungi in small cardamom. . She is  one of the the editors of the book “Cardamom [Elettaria cardamomum (L.)MATON] :Production, Breeding,Management, Phytochemistry And Health Beneifits”  published by Nova scientific publishers,New York.
