Abstract
Disclosed herein is a method for preventing deterioration of an industrial material by using an azole derivative represented by the following formula ##STR1## wherein X means a halogen atom or a C.sub.1 -C.sub.5 alkyl, haloalkyl, phenyl, cyano or nitro group, n stands for 0 or an integer of 1-5, A denotes a nitrogen atom or CH, R.sub.1 and R.sub.2 mean individually a hydrogen atom or a C.sub.1 -C.sub.5 alkyl group, R.sub.3 denotes a hydrogen atom or a C.sub.1 -C.sub.3 alkyl group, and when n is an integer of 2-5, Xs may be the same or different. A biocidal composition for the method is also disclosed.
