Abstract:
Experiments were conducted in the seed pathology laboratory Department of Plant
Pathology. Sher-e-Bangla Agricultural Univ ersity Lo evaluate some ccofricndly treatments
and fungicides on seed germination and incidence of Bipolaris sorokiniana of wheat Seed
treatments with fungicides reduced the incidence of Bipolaris sorokiniana over untreated
control. The lowest incidence was counted (2.31%) in apparently health) seed treated with
Ridomil gold M7 68 WP @ 0.2%. The highest seed germination (94.17%) was recorded in
apparently health) ... eed treated with brine solution @ 2°'o for 1 5 minutes followed by
solarized apparently health) seed for 5 hours (99.33?to), polythene solarized apparently
health) seed for 5 hours (99.00%1), apparently health} seed treated with hot water at 52°C for
I 0 minutes (99.00o/o) and Burrnuda grass extract (99 60° o}. Comparatively the lowest
incidence of Bipolaris sorokiniana l l .50°0) was observed in apparently healthy seeds treated
with hot water at 52°C for '.!O minutes followed by polythene solanzed apparently healthy seeds for 15 hours (5.00'Yo). apparently health) seeds solarized for 15 hours (6.00°0),
apparently healthy seeds treated with brine solution a .2° o for 30 minutes ( 13.00° o) and
apparently healthy seeds treated with Necm extract l 14.00u'o ).
