Cooperative microbicidal and acaricidal composition containing two or three kinds of active components

PURPOSE: To obtain a composition containing N-alkyl(ene)-N-(O,O)-disubstituted thiophosphoryl)-N',N'-disubstituted glycinamide and triforinene or mancozebe, etc., and having microbicidal and acaricidal activities. CONSTITUTION: This composition is obtained by mixing a compound of formula I (R 1 , R 2 are each an alkyl, an alkoxy, a cycloalkyl, an alkenyl, phenyl, etc.; R 3 is an alkyl, an alkenyl, etc.; R 4 , R 5 are each an alkyl, an alkenyl, phenyl, etc., or R 4 or R 5 together with N form a hexamethylenimino group) having acaridical activity with one or two kinds of compounds having microbicidal activities selected from triforine, copper-oxy-quinolate, cycloheximide, mancozebe, compounds of formula II (R 7 is an alkyl, amino, etc.; R 8 is H, CONHC 4 H 9 , etc.; R 9 to R 12 are each H, a halogen, an alkyl, etc.), etc. The mixing ratio is (10:1) to (1:10) or (10:1:1) to (1:1:10).
