    • An article for the sustained release of an insecticide into the ambient air comprises an elastomeric matrix, with the insecticide dissolved in the matrix. The matrix material has a modulus between about 10.sup.4 Pa and about 10.sup.8 Pa at 23.degree. C., and a glass transition temperature less than 0.degree. C. The matrix comprises polyurethane formed by reacting hydroxyl-terminated polybutadiene or polyisoprene and 4,4' diphenylmethane diisocyanate, and the insecticide is 2,2' dichlorovinyl dimethyl phosphate. The insecticide-containing matrix is contained in a plastic bottle, and typically protected against inadvertent skin contact by means of a dermal barrier. The article also comprises means for activating the article such that, prior to activation, release of insecticide into the ambient air is prevented, whereas such release can take place after activation. Exemplary activation means comprise a metal foil seal of the plastic bottle. The article is effective in controlling insect infestation (e.g., ants, fire ants, bees, wasps, cockroaches) in enclosures, e.g., enclosures of the type used to protect outdoor utility equipment.
    • 用于将杀虫剂持续释放到环境空气中的物品包括弹性体基质，其中杀虫剂溶解在基质中。 基体材料在23℃下的模量为约104Pa至约108Pa，玻璃化转变温度低于0℃。基体包含通过羟基封端的聚丁二烯或聚异戊二烯和4,4'-二苯基甲烷 二异氰酸酯，杀虫剂为2,2'二氯乙烯基二甲基磷酸酯。 含有杀虫剂的基质包含在塑料瓶中，并且通常通过真皮屏障防止无意的皮肤接触。 制品还包括用于活化制品的装置，使得在活化之前，防止杀虫剂释放到环境空气中，而这种释放可以在活化后进行。 示例性的激活装置包括塑料瓶的金属箔密封。 该文章有效地控制了外壳中的昆虫侵染（例如蚂蚁，火蚁，蜜蜂，黄蜂，蟑螂），例如用于保护户外公用设备的类型的外壳。

    • A VULCANIZED ELASTOMERIC COMPOSITION COMPRISING AN ORGANIC ELASTOMER, AN ORGANIC TOXICANT DISSOLVED THEREIN, AND SELECTED PROPORTIONS OF COMPOUNDING INGREGIENTS INCLUDING CARBON BLACK, WAX, FILLERS, ETC,. AND VULCANIZED TO AN INTERMEDIATE DEGREE ARE BIOCIDAL MATERIALS HAVING A LOW, CONTROLLED AND TAILOR-MADE RATE OF TOXICANT RELEASE FOR LONG-EXTENDED BIOCIDAL ACTIVITY. ORGANIC ELASTOMERS EMPLOYED ARE NATURAL RUBBER, NEOPRENE, NITRILE RUBBERS, BUTYL, SBR, POLYBUTADIENE, ETC. ORGANIC TOXICANTS APPRECIABLY SOLUBLE IN SUCH ELASTOMERIC COMPOSITION FOR SUCH USE INCLUDE THE ORGANO-TIN COMPOUNDS, NITROSALICYLANILIDE COMPOUNDS, CHLORINATED HYDROCARBONS, ORGANO-PHOSPHOROUS COMPOUNDS, ETC. SUCH COMPOSITIONS ARE USEFUL IN SHEET-LIKE COVERINGS THICKER THAN ABOUT 0.05 INCH FOR ANTIFOULING PROTECTION OF SUBMERGED MARINE STRUCTURES; AS LARVACIDES IN THE FORM OF PELLETS, CHUNKS, SHEETS, STRIPS, TAPES, ETC., WHICH ON IMMERSION IN INFESTED WATER OR AIR LIBERATE TOXICANT KILLING THE ADULT, LARVAE AND EGG FORMS OF MOSQUITOS, MIDGES, BLACK FLIES, SCHISTOSOME CERCARIAE AND THEIR SNAIL HOSTS, OTHER GASTROPODS, AND AND OTHER DISEASE-CAUSING AND/OR DISEASE TRANSMITTING ORGANISMS AND INSECT PESTS; AS BACTERIOCIDAL, FUNGICIDAL AND ALGICIDAL SURFACES AND COVERINGS; AND AN ANIMAL- AND INSECT-REPELLANTS. CERTAIN INGREDIENTS OF ELASTOMER AND VULCANIZABLE RUBBER COMPOSITIONS, NOTABLY FATTY ACID MATERIALS, VERY MATERIALLY ENHANCE BIOCIDAL EFFICIENCY OF COMPOSITIONS CONTAINING THE ORGANO-TIN COMPOUNDS.

    • Paints are protected against attack by fungi and bacteria by applying to the surface of said material or incorporating therein a bismuth compound of the formula R13BiX2 or RnBiX3-n, wherein n is 1 or 2, X is a monovalent anionic atom or group of two X's when taken together represent a divalent anionic atom or group, R1 is a substituted or unsubstituted aryl group and R is a substituted or unsubstituted alkyl, cyclo-alkyl, alkenyl or aryl group. X may be a halogen, e.g. F, Br, Cl, oxygen, sulphur, carboxylate, phenoxide, mercapto propionate; hydroxybenzoate, amino benzoate, chloroacetate, tartrate isooctyl mercapto-acetate methacrylate, acrylate, thiocyanate, alkoxide, hydroxide, acetate, salicylate, benzoate, or cyanide group.
