Background : In previous studies, adlay seeds showed a prevalence of diversified fungal flora with the predominant fungal genera being Fusarium (45.6%) and In vitro test showed that fungal toxins like Fumonisin and Zearalenone were produced by Fusarium fujikuroi, F. asiaticum and F. graminearum. Because of this we performed experiments to selecting disinfective chemicals for controlling the Fusarium contamination in the adlay seed. Methods and Results : We carried out the chemical efficacy test such as seed disinfectants selection test appling before planting and pesticides selection test using in the earing season. In the present study, eleven different commercially available seed disinfectant were applied to the adlay seeds. Among 11 seed disinfectants, Hexaconazole+Prochloraz emulsifiable concentrate (EC) and Prochloraz emulsifiable concentrate (EC) had control value of 80% or above against Fusarium species tested. In the pesticides selection test, seven different commercially available pesticides for Fusarium blight (Scab) control were applied and we observed that Metconazole suspension concentrate(SC) strongly inhibited the mycelial growth of 10 Fusarium species all. Conclusion : From the above results, we selected Hexaconazole+Prochloraz EC and Prochloraz EC as a seed disinfectants and Metconazole SC as a pesticide using in the earing season for Scab control.
