Overview

Observational analysis reveals diverse rhizoctonia species infecting rice, highlighting management needs.

Key Points

  • Thirty-seven rhizoctonia isolates were collected from various rice-growing regions in Tamil Nadu, confirming diversity.
  • PCR analysis revealed an amplicon size of 265 bp in R. solani isolates, confirming their classification within AG1-IA.
  • Highly virulent R. solani and R. oryzae-sativae isolates were found to infect multiple plant species except pig weed and khaki weed.
  • The study stresses the need for effective management strategies to mitigate the impact of sheath blight on rice production.
