Abstract: A low volatile organic compound co-solvent system is disclosed for preparing emulsion concentrates of low melting organophosphorous insecticides wherein the bioefficacy of the insecticide active is significantly enhanced. The co-solvent system comprises a water-soluble ethoxylated fatty acid/rosin acid-nonionic surfactant composition.

Abstract: Novel chemotherapeutic agents having utility in treating infectious diseases such as periodontal disease, certain urinary tract infections, and infectious urinary tract stones, are obtained by combining chemically a diphosphonate compound with a therapeutic agent effective against the foregoing diseases.

Abstract: The invention comprises a composition of matter containing a matrix, a plasticizer and pyriproxifen for controlling fleas.

Abstract: The invention comprises a method of controlling fleas which includes continuously administering to the haircoat of a homeothermic animal an ovicidally effective amount of 2-(1-methyl-2-(4-phenoxyphenoxy)ethoxy)pyridine (pyriproxifen) from a sustained release matrix at a rate of 0.1 mcg/kg/day to 100 mcg/kg/day. The method may also include the use of additional ingredients such as insecticides, plasticizers, lubricants and antioxidants in a sustained release matrix.

Abstract: The present invention produces alkyldiphosphonic acid derivative of the general formula: ##STR1## wherein Het is a heteroaromatic five-membered ring containing to 3 heteroatoms which can be partly hydrogenated and optionally substituted one or more times by alkyl, alkoxy, phenyl, cyclohexyl, cyclohexylmethyl, halogen or amino, and two adjacent alkyl substituents can together also form a ring, Y is a hydrogen atom or a lower alkyl radical, X is a hydrogen atom, a hydroxyl group or an amino group optionally substituted by lower alkyl and R is a hydrogen atom or a lower alkyl radical, with the proviso that Het is not a pyrazole ring; as well as the pharmacologically acceptable salts thereof.

Abstract: Oxime N-alkyl-N-.alpha.-(alkylthio-phosphorothio)acyl carbamates represented the structure: ##STR1## wherein the R represents various imino radicals, Q is oxygen or sulfur and the numbered R groups represent various alkyl substituents, which exhibit superior insecticidal and miticidal activity.
