Other claims from this paper (11)
- Observation A 2022 survey in three groundnut-growing districts of Tamil Nadu found stem rot incidences ranging from 16.57 % to 39.55 %.
- Observation The highest stem rot incidence was recorded in the Kalpadai region of Kallakurichi.
- Observation Pathogenicity assays identified the Sr3 isolate of the stem rot pathogen as the most virulent, causing 44.85 % disease incidence.
- Association Principal Component Analysis showed that pathogenic variability negatively affected yield traits (seed length, plant height and shelling percentage) in groundnut.
- Intervention effect The native biocontrol agent Trichoderma asperellum Tr4 significantly inhibited S. rolfsii mycelial growth by 88.88 %.
- Intervention effect The native biocontrol agent Bacillus licheniformis B5 significantly inhibited S. rolfsii mycelial growth by 70.55 %.
- Intervention effect Vermicompost suppressed growth of the pathogen Sclerotium rolfsii by 88.22 % in the poisoned food technique.
- Intervention effect Neem cake extract (20 % concentration) suppressed growth of the pathogen Sclerotium rolfsii by 78.01 % in the poisoned food technique.
- Observation T. asperellum Tr4 and B. licheniformis B5 were mutually compatible and also compatible with vermicompost and neem cake.
- Intervention effect Combined treatments of bioagents with vermicompost and neem cake reduced stem rot incidence in groundnut in pot and field trials.
- Intervention effect Combined treatments of bioagents with vermicompost and neem cake improved yield parameters in groundnut in pot and field trials.
