Abstract:

The experiment was carried out to estimate the prevalence of seed-borne fungi of country bean at laboratory condition. Before placed, the seeds were treated with six different treatments namely Autostin 50WP, Aimcozim 50WP, Ata leaf extract (1:2 w/v), Neem leaf extract (1:2 w/v), Biskatali leaf extract (1:2 w/v) and Mahogani leaf extract (1:2 w/v). In laboratory, different seed-borne fungi like Aspergillus niger, Cercospora sesami, Rhizopus stolonifer, Alternaria sp. and Fusarium oxysporum were detected from the collected seed sample by blotter method. After 7 days of incubation, germination percentage varied significantly and ranged from 33.3% to 83.3%. The highest germination was found in Autostin 50 WP (83.3%) which was statistically similar with Aimcozim 50 WP (77.8%) and among botanicals the highest germination was recorded from the treatment Biskatali leaf extracts. Autostin 50 WP was found as the best seed treating chemicals in controlling seed borne fungi Aspergillus niger, Alternaria sp., Fusarium oxysporum, Rhizopus stolonifer and Cercospora sesame compared to all other treatments.
