An experiment to study the effect of different paddy seed storage structures such as metal bin, paddy straw ball, Ghyampo, mud bin (Dehri) and jute bag on survivability of Drechslera oryzae, was conducted in randomized complete block design at Rampur, Chitwan. Three were three replications. Five kilograms seed of Masuli variety with nine percent initial infection of Drechslera 0ryzaewas stored in each storage structure. Percentage of infected gr ains was assessed using blotter technique at two months interval. Assessments were done on 24 November, 22nd January, 22"d March, 5th June and 24th July 1997. Percentage of infected seed grains was decreased to three percent from nine percent during whole storage period in metal bin. However, the effect of other storage structures was inconsistent in decreasing percentage of infected seed grains during storage………….
