    EVALUATION OF FUNGICIDES AND SOME ECOFRIENDLY TREATMENTS AGAINST Bipolaris sorokiniana
    (Department of Plant Pathology, Sher-e-Bangla Agricultural University, 2007-12) PANNA, ROKSHANA
    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 ).
