Triasoloprimidiini derivaatide kasutamine mikrobitsiididena materjalide kaitsmisel

Use of triazolopyrimidine derivatives (I), or their metal salts, acid addition compounds, N-oxides and, where a chiral center is present, R and S isomers or racemates, as microbicides for protection of technical materials. Use of triazolopyrimidine derivatives of formula (I), or their metal salts, acid addition compounds, N-oxides and, where a chiral center is present, R and S isomers or racemates, as microbicides for protection of technical materials. R = optionally substituted alkyl, alkenyl, alkynyl or cycloalkyl; R = H or alkyl, or R and R together complete an optionally substituted heterocycle; R = optionally substituted aryl; R = H or halo. Independent claims are also included for the following: (1) Method for protecting technical materials against attack and/or destruction by microorganisms, by treatment with at least one (I); (2) Microbicidal composition for technical materials comprising (I), at least one diluent or solvent, optionally also processing auxiliaries and other antimicrobial compounds; and (3) Technical materials containing at least one (I).
