Seed borne fungi were inspected with Blotter Method in rice cv. Khao Dawk Mali 105 obtained from two farmers rice storehouses. Isolation and identification of the fungi were made on PDA and found two major field pathogens Fusarium moniliforme and F. semitectum together with saprophytic and storage fungi. Efficacy test of dried turmeric rhizomes water extract for seed treatment on the rice seed after 3 months storage was made, using seed dressing and seed soaking methods. Results showed that seed soaking method gave best control, reduced percentage of seed damage when compared with seed dressing and control treatments. Measurement on effect of the extract on seed damage and growth of seedlings (root length, stem height and dried weight of the whole plant), using Standard Soil Method, indicated that both methods gave much better results than control treatment, statistically different at 95 percent level.
