The present invention relates to the use of thiadiazoles of the type ##STR1## in which R.sub.1, R.sub.2 and R.sub.3 = hydrogen, alkyl groups having 1-4 carbon atoms substituted alkyl groups having 1-4 carbon atoms which are substituted by halogen, carboxyl, hydroxyl or nitro group, an alkoxy CN, halogen, NO.sub.2 or COOR in which R=H or alkyl groups 1-4 carbon atoms, and the use of synergistic combinations of thiadiazoles with other biocidal substances as biocides for material protection. The compounds according to-the invention, which are distinguished by a broad, biocidal action spectrum, can be used in particular for wood preservation for preventing the destruction of wood by fungi or bacteria, for the biocidal treatment of plastics and as preservatives or disinfectants. The recommended concentrations for use are 0.01 to 15 percent by weight-preferably 0.1-3.0 percent by weight.
A wood preservative comprising a wood preserving effective amount of a compound of the formula:
The wood preservative according to claim 7 wherein the compound is present in concentrations ranging from 0.05 to 5% by weight.
A method for preserving wood which comprises applying to a surface a wood preservative comprising an effective amount of a thiadiazole of the formula:
A method for protecting substances consisting of textiles, paints, plastics and building materials from microoorganisms which comprises applying to said substances a biocidal effective amount of a compound having a formula:
