A new biological fumigation agent of 20% Isothiocyanate AS was studied for the effect of soil disinfection on greenhouse strawberry using drip irrigation system. The results showed that 20% Isothiocyanate AS showed significant control efficacies against bacterium and fungi （including Fusarium, Pythium, Aspergillus, Penicillium, etc. ）. Its control effect against Fusarium could reach 100 % , but against actinomycetes it had not distinct effect. After soil disinfection by Isothiocyanate AS in greenhouse, the survival rate of strawberry increased significantly during the whole growing period. Isothiocyanate can be applied to strawberry cultivation.
