ABSTRACT

Thirty six rice seed samples of varieties BR6, Pajam and Joya were collected from Parshuram upazila, Feni district of Bangladesh and nine seed-borne fungi were detected from these seed samples. The identified fungi were Fusarium oxysporum, F. moniliforme, Bipolaris oryzae, Alternaria padwickii, Curvularia lunata, Aspergillus flavus, Aspergillus niger, Penicillium sp. and Nigrospora oryzae. Five different plants extracts viz. garlic, allamanda, neem, chirata and bishkatali with two dilutions (1:1 & 1:2) were tested for seed treatment. Garlic extract (1:1) dilution found best for three varieties which successfully reduced seed-borne infection and also increased seed germination up to 68.39% over control. Neem (1:1) and chirata (1:1) extracts also increased seed germination up to 66.09% and 67.81%, respectively. Based on the present study, it may be concluded that among the five plant extracts with two dilutions (1:1 & 1:2), garlic (1:1) is most effective in controlling seed-borne fungal flora of rice followed by neem (1:1) and chirata (1:1) extract.
