Abstract:
The present report describes Choanephora infundibulifera as causal pathogen of twig blight of Pisum sativum
recorded from the Gangetic alluvial region of West Bengal, India. Severe disease infestation with the initiation of shoot
apical meristem, leaf and blossom blight was observed. The monsoon season (June-September) with optimum temperature
(28-30°C) and high moisture (80-90%) level was found to enhance the disease progress. The pathogen was identified based
on its cultural, morphological, and the internal transcribed spacer (ITS) - r DNA sequence analysis. To our understanding,
this pathogen is being described for the first time as causal agent of twig blight disease of pea in India.
