Abstract: N-phosphoryl- or N-thiophosphoryl-N'-s-triazinylformamidines of the formula ##STR1## wherein R.sub.1 and R.sub.2 independently of one another are each C.sub.1 -C.sub.20 -alkyl, or phenyl unsubstituted or substituted by halogen atoms,R.sub.3 is C.sub.1 -C.sub.6 -alkyl or C.sub.3 -C.sub.6 -cycloalkyl,R.sub.4 is hydrogen, C.sub.1 -C.sub.6 -alkyl or C.sub.3 -C.sub.6 -cycloalkyl, andX and Y are each oxygen or sulfur.A process for producing these triazines and their use for controlling pests are described.

Abstract: Halogenoalkylcarbamic acid esters of the formula ##STR1## in which R, R.sup.1 and R.sup.2 independently of one another represent methyl which is optionally substituted by halogen, at least one of the methyl groups R, R.sup.1 and R.sup.2 being substituted by at least one halogen atom,R.sup.3, R.sup.4 and R.sup.5 are identical or different and individually represent hydrogen or optionally substituted alkyl andn represents 0 or 1,synergize the action of known arthropodicides.

Abstract: The present invention relates to combating pests with five-membered nitrogen-containing heterocyclic compounds of the formula (I) ##STR1## in which R.sup.1, R.sup.2, R.sup.3, X and Y have the meaning given in the description. Many of the compounds are new.

Abstract: Disclosed is a tablet for disinfecting flush toilets comprising from about 20% to about 90% alkali metal salt of dichloroisocyanuric acid and at least about 5% of either sodium bromide or potassium bromide. Also disclosed is a method of using the tablet.

Abstract: A biocidal composition is formed from an organotin compound covalently bonded to reactive silanol sites present on the surface of a silica compound to form a solid biocidal particle. Further, the solid biocidal particle can be admixed with a carrier or film-forming vehicle. A method of protecting a surface from fouling organisms is also provided by coating the surface with the subject biocidal composition while it is dispersed in a carrier or film-forming vehicle.

Abstract: N-Phosphoryl- or thiophosphoryl-N'-s-triazinylformamidines of the formula ##STR1## wherein R.sub.1 and R.sub.2 independently of one another are each C.sub.1 -C.sub.20 -alkyl, or phenyl unsubstituted or substituted by halogen, andX and Y are each oxygen or sulfur.A process for producing these triazines and their use for controlling pests are described.

Abstract: Phosphoric acid esters of the formula ##STR1## wherein X is CH or N,Ar is optionally substituted phenyl, diphenyl or naphthyl,R is cyano, carboxylic acid ester, carboxylic acid thioester or carboxylic acid amide.R.sub.10 is alkyl,R.sub.11 alkyl, alkoxy, alkylthio or phenyl, andY is sulfur.For R: the ester groups are alkenyl, alkynyl, cycloalkyl, optionally substituted phenyl, alkyl interrupted by oxygen or sulfur and optionally substituted by halogen, phenyl, carboxylic acid ester, alkylcarbonyl, optionally substituted phenyl carbonyl, or a C.sub.5 or C.sub.6 heterocycle; the thioester groups are alkyl or optionally substituted phenyl or benzyl; the amide is optionally mono- or di-substituted by alkyl, cycloalkyl, optionally substituted phenyl or benzyl, or may form a C.sub.5 or C.sub.6 heterocyclic ring. The compounds are useful in controlling phytopathogenic fungi.
