Zusammenfassung:PURPOSE: To obtain a synergistic fungicidal composition containing a 2-(O- substituted alkyl)-2-thio-1,3,2-oxathiaphosphorane derivative and kerocarb and/or benomyl and enabling the increase of activity spectrum or the reduction of the application amount. CONSTITUTION: This composition is produced by using (A) a compound of the formula (R1 to R4 are each H, a 1-6C alkyl, a 2-6C alkenyl or a 2-6C alkynyl; X is a halogen, H, a 1-6C alkyl or mercapto) such as 2-(O-2'-chloroethyl-)-2- thiothiaphosphorane and (B) Zn and Mn complex (1:1) of 8-quinolate dimethyl- dithiocarbamate and/or (C) benomyl at an A:(B or C) ratio of 10:1 to 1:10 and A:B:C ratios of 0:1:1 to 1:10:10 and compounding the components with conventional carrier and/or additive. The combined use of the components A and B increases the activity spectrum and that of the components A and C is effective for remarkably decreasing the amount of the active component C having total activity.
