Abstract: The invention relates to a method for the preventive protection of materials against pests permanently and/or temporarily living in the soil, in particular, termites. One or more barriers of sharp-edged inert particles of a particle size screened at from 0.001 to 30 mm and/or spherical inert particles having a diameter of 0.5 to 5.0 mm are arranged around and/or in the object to be protected.

Abstract: The present invention relates to a composition for use as an agent or concentrate for the preservation of wood and wood materials, which comprises 0.05 to 25% by weight of a 1-aryl-3-hydroxy -3-alkyl-4-(1,2,4-triazol-1-yl)-butane derivative and 0.002-5% by weight of a pyrethroid insecticide comprising cyano-(4-fluoro-3-phenoxyphenyl) -methyl 3-(2,2-dichloroethenyl)-2,2-dimethylcyclopropanecarboxylate, (.+-.).alpha.-cyano-3-phenoxybenzyl (.+-.)-cis,trans-3-(2,2-dichlorovinyl)-2,2 -dimethylcyclopropanecarboxylate, (S).alpha.-cyano-3-phenoxybenzyl (1R,3R)-3-(2,2-dibromovinyl)-2,2-dimethylcyclopropanecarboxylate or 3-phenoxybenzyl (.+-.)-cis,trans-3-(2,2-di-chlorovinyl)-2,2-dimethylcyclopropanecarboxylat e or enantiomeric compounds thereof and more than 40% by weight of a solvent and/or diluent as well as, if appropriate, an organic chemical binder and/or fixing agent, processing aids, dye, pigment, dye mixture or pigment mixture.

Abstract: An aqueous composition for preserving wood and wood materials comprising a fungicide selected from the group consisting of 1-[[2-(,4dichlorophenyl-4-propyl-1,3-dioxolan-2-yl]methyl]-1H-1,2,4- triazole, (common name propiconazol) and .alpha.-[[2-(4-chlorophenyl)ethyl]-.alpha.-(1,1-dimethylethyl)-1H-1,2,4-tr iazol-1-ethanol; a fungicidal carbamate; namely 3-iodo-2-propynylbutyl carbamate or methyl benzimidazol-2-ylcarbamate; a stabilizer, 2,2,4-trimethyl-1,3-pentadiol monoisobutyrate, and a diluent. The composition can optionally comprise an insecticide, an emulsifier, a wetting agent and an organic-chemical binder or fixing agent.

Abstract: The process of detecting the presence of insects or insect larvae in a solid substrate, e.g. wood, in which the behavioral patterns of the insects to be detected are established. These behavioral patterns are compared to actual noise and vibration patterns detected in the substrate, after extraneous noise is filtered from the actually detected information and the data has been converted to analog form. The actual analysis is performed by a microcomputer. The microcomputer analysis yields an output indicative of damage or movement activity or lack of such activity.

Abstract: The present invention relates to a wood preservative comprising either(1) at least one of (a) ammonium monofluorophosphate and/or diammonium monofluorophosphate of the general formula (R.sub.1 R.sub.2 R.sub.3 R.sub.4 N)R.sub.5 PO.sub.3 F in which R.sub.1, R.sub.2, R.sub.3 and R.sub.4 are identical or different and each denotes a straight-chain, branched or cyclic, saturated or unsaturated alkyl, aralkyl, alkyaryl or aryl radical, either unsubstituted or substituted by an alkyl, alkoxy or a hydroxyl group, up to three of the four R.sub.1 -R.sub.4 can be hydrogen or can together form an alkylene bridge, R.sub.5 is a hydrogen atom or a R.sub.6 R.sub.7 R.sub.8 R.sub.9 N group in which R.sub.6, R.sub.7, R.sub.8 and R.sub.9, respectively, have the same meanings as R.sub.1, R.sub.2, R.sub.3 and R.sub.4, respectively, and (b) a mixture of a salt of monofluorophosphoric acid and at least one ammonium salts of the general formula R.sub.1 R.sub.2 R.sub.3 R.sub.

Abstract: A wood preservative based on leaching-resistant, inorganic compounds for protection of wood and wood materials against wood-damaging insects and fungi, including wood-rot fungi, is disclosed. The wood preservative, which is fixed without chromium, contains as active ingredient in an aqueous solution which is stable on impregnation, (a) a Cu(II), Zn, Ni, Co, Fe, Mg and/or Mn salt of monofluorophosphoric acid, or (b) an alkali metal salt and/or ammonium salt of monofluorophosphoric acid, in the presence of a Zn, Ni, Co, Fe, Mg and/or Mn salt of hydrochloric, nitric or sulfuric acid and, optionally in addition to (a) or (b), one or more members of the group comprising NH.sub.3, HCl, HNO.sub.3, H.sub.2 SO.sub.4, HF, alkali metal hydrogen fluoride and ammonium hydrogen fluoride. Alternately, the composition contains (c) an alkali metal salt and/or ammonium salt of monofluorophosphoric acid in the presence of a Cu(II) salt of hydrochloric, nitric or sulfuric acid in a Cu.sup.2+ :PO.sub.3 F.sup.
