Identifies Rhizoctonia solani as the cause of sheath blight in rice, highlighting its implications for crop management.

The aim was to isolate and characterize the fungal pathogen causing sheath blight in rice.
Isolated eight fungal strains from paddy fields in Alor Setar, Kedah, Malaysia.
Performed morphological characterization and pathogenicity assays on rice stems.
Used internal transcribed spacer (ITS) sequencing for molecular identification.
Isolate R1 (USM-PD2) confirmed as Rhizoctonia solani with 100% similarity to GenBank reference.
Pathogenicity assays showed lesion areas of 6.00-7.83 cm² with a severity of 66-87%.
Phylogenetic analysis clustered R1 closely with other R. solani isolates.

Shukri et al. (2026) studied this question.
