Phytophthora workshop held in India

A workshop on "Rapid Diagnostic Tools for Identification of Phytophthora species on Horticultural Crops " organized by Dr. Jean Ristaino, with the assistance of Dr. Pallem Chowdappa and Dr. David Cooke was held at the ICAR- Central Plantation Crops Research Institute, Bangalore India, Sept 8, 2015 preceding the 3rd International Phytophthora Symposium, Sept 9-12.  Over 120 participants applied for the workshop that included 30 students from diverse research institutes in India. The hands on laboratory training in morphological and molecular identification of Phytophthora species included use of a diagnostic Lucid key, PCR and molecular sequence based identification and rapid assays for identification of Phytophthora infestans.  

A workbook was distributed to workshop participants and is available here

Late blight and other Phytophthora diseases emerging in India

Late blight and other Phytophthora diseases emerging in India

Over a hundred and twenty different Phytophthora species affect tropical and horticultural crops globally and are an emerging problem in India. A 4-day symposium organized by Dr. Pallem Chowdappa of the ICAR-Central Plantation Crops Research Institute on “Phytophthora: Taxonomy, Genomics, Pathogenicity, Resistance and Disease Management was held in Bengaluru India Sept 9-12.  The meeting included plenary presentations by invited international guests on emerging Phytophthora diseases, taxonomy and phylogeny, population biology, genomics, pathogenesis, epidemiology, host resistance and disease management. 

A team of international Phytophthora researchers gave plenary talks on:

  • Current and emerging Phytophthora diseases – research challenges and impact - Dr. André Drenth
  • Evolutionary origins of US and famine-era lineages of Phytophthora infestan - Dr.  Jean Ristaino
  • New tools to understand evolving populations of Phytophthora infestans on regional, national and international scales for improved late blight management - Dr. David Cooke-
  • Genome evolution in filamentous plant pathogens- Dr. Sophien Kamoun
  • From genomics to effectors: how understanding oomycete biology has contributed to disease control - Dr. Brett Tyler
  • Management of Phytophthora diseases in the tropics - Dr. David I. Guest
  • Management of Phytophthora blight (Phytophthora capsici) of peppers - Dr. M. Babadoost
  • The 30 year journey: Integrated Phytophthora root rot management in avocados- Dr. Elizabeth Dann
  • In search for new targets to control Phytophthora pathogens - Dr. Francine Govers

The well-attended meeting also included inaugural and cultural events, a field tour, a trade show and a valedictory honors ceremony.  A symposium report and recommendations for future Phytophthora research in India were given by the international team. The team of late blight researchers met with Indian late blight researchers and discussed the need for global monitoring of Phytophthora infestans populations. Dr. Pallem Chowdappa reported the emergence of the 13_A2 lineages of the pathogen in India and its shift to tomato.  Dr. Sanjoy Guha Roy from West Benagal State University discussed his work on characterizing late blight outbreaks in the northwest of the country in 2014.  Dr. Sanjeev Sharma from the Central Crops Research Institute in Shimia presented data on a decision support system for late blight, development of transgenic varieties and characterization of populations in India.  The need for coordination among the Indian and global research teams including Euroblight and USAblight and a global monitoring network for late blight were discussed.

3rd International Symposium - Phytophthora: Taxonomy,Genomics, Pathogenicity, Resistance & Disease Management

Biennial Euroblight Meeting

The biennial meeting of the European network Euroblight, which tracks European outbreaks of late blight, was held this May in Romania.  The meeting included colleagues from North America, South America, and Asia, as well as Europe, and represents a step towards developing a global strategy for tracking and managing late blight.  Read more.
