First report of Fusarium proliferatum causing rhizome rot disease of turmeric (Curcuma longa L.) in Uttar Pradesh, India
摘要
The rhizome rot disease of turmeric (Curcuma longa L.) was observed during the survey (August to January, 2022) at the farmer’s field (26.9582 N, 81.2999 E"), Barabanki, UP, India. The isolated fungus was identified as Fusarium proliferatum based on morphological characteristics and molecular markers, including two genetic regions (ITS and beta tubulin) and phylogenetic studies. After that, a pathogenicity test was conducted to fulfil Koch’s postulates, confirming it as a causal agent of rhizome rot disease of turmeric. In light of the significant impact on the crops' yield and quality of turmeric, this report identifies F. proliferatum as a significant contributor to the turmeric rhizome rot complex, highlighting the need for revised management strategies targeting this specific pathogen to mitigate significant yield losses in the particular agro-climatic region of India.
