Background : The aim of the present study was to identify an effective physicochemical control method to reduce Fusarium species infestation in adlay (Coix lacryma-jobi L.) before and after harvesting. Methods and Results : We observed that prochloraz emusifiable concentrate and hexaconazol prochloraz emusifiable concentrate strongly inhibited the mycelial growth of 10 Fusarium species. Strong growth inhibitions and cell lysis were observed following treatment with 4% NaOCl solution. The total number of fungi detected were lower follwing treatment with thiophanatemethyl triflumizole wettable powder (), hexaconazol prochloraz emulsifiable concentrate (), carboxin thiram dustable powder () and prochloraz emulsifiable concentrate () than in the non-treated control (). The reduction of Fusarium fungi varies with the concentration and soaking time of NaOCl solution. Fungal detection was not observed after soaking in NaOCl solution for 24 h and harmful effects were not observed for plant growth by NaOCl after soacking for 6 - 12 h. Conclusion : Soaking seed for 6 - 12 h in 4% NaOCl could be an effective method of disinfectant treatment for the control of Fusarium fungi in adlay seeds.
