Abstract: The present invention relates to emulsifiable concentrate compositions of phosphorodithioates, especially [S-1,2-bis-(ethoxycarbonyl)ethyl] O,O-dimethylphosphorodithioate, known as malathion insecticide, containing vegetable oils as the solvent. These compositions not only form stable such emulsions but are even stable when diluted with water.

Abstract: The invention provides insecticidal compositions for combatting aphids, which compositions contain an aphid insecticide in an amount lower than the minimum usual percentage for said insecticide in an aphicidal composition and an alarm pheromone for aphids. The compositions of the invention are less toxic because of the reduced insecticide content but they are not less effective than the insecticidal compositions which do not contain an alarm pheromone.

Abstract: An insecticide preparation which may be either aerosolized or non-aerosolized is in the form of a dispersion with normally distinct sharply delineated water and active ingredient phases. The preparation contains a dispersal agent consisting of cocodiethanolamide within the range of 0.1 to 10% by weight of the preparation and with the preparation having a pH within the neutral range of approximately 6.5 to 7.

Abstract: Infestation of cockroaches in buildings and houses are treated and effectively eliminated by determining the location of the eggs or the young, immature insects and treating them with a suitable insecticide before the insects emerge and begin to migrate to other areas. The treatment can also be applied to mature roaches in these areas before they lay their eggs. Frequently the places where the young roaches develop or hatch is in the foundations and walls of buildings and under concrete slabs where sewer or water lines occur and other damp or humid areas. A particularly effective insecticide has been found to be a dilute solution of O, O-diethyl-O- (2-isopropyl-6- methyl-4 pyrimidinyl phosphorothioate which is used to saturate the area being treated.

Abstract: Mixtures of organic insecticides of the organophosphate types or of the carbamate type, with certain fatty acids or their salts, have been found to have enhanced insecticidal activity. The fatty acids found operative are the unsaturated 18-carbon atom ones. The mixtures are toxic to both sucking insects and defoliators. The weight ratio of organophosphate or carbamate to fatty acid can range from about 1:1 to about 1:200 respectively. The amounts of the organophosphate or carbamate required for substantial effectiveness can be reduced significantly by concurrent use of the fatty acid. The fatty acid is more environmentally acceptable than the other types of insecticides mentioned. This unique composition can be used to protect against a broader range of insects.

Abstract: A composition of matter and method of making the composition which relates to an all aqueous, phase stable emulsion of organophosphorous pesticides which is free of organic solvents. The composition comprises from about 40 to 95 percent by weight of an organophosphorous selected from the group consisting of phosphates, phosphorothioates and phosphorothionates, and mixtures thereof, from about 3 to 10 percent by weight of an nonionic block, heteric, heteric/block copolymer of ethylene oxide and propylene oxide, from about 3 to 16 percent by weight urea, and about 20 to 50 percent water. The composition is made by blending these components together under moderate agitation.

Abstract: An emulsifying dispersant is disclosed which is a nonionic surface active agent substantially free of a terminal primary hydroxyl group, obtained by esterifying or etherifying a terminal hydroxyl group of an alkylene oxide adduct of a hydroxyl compound or an alkylene oxide adduct of a carboxyl compound. This emulsifying dispersant is remarkably effective for preventing decomposition of a biocidal agent and for emulsifying the biocidal agent. A biocidal preparation formed using this emulsifying dispersant has good storage stability and good emulsion stability.

Abstract: Emulsifiable concentrates of malathion having low eye irritation properties. Compositions of the invention yield stable emulsions when diluted with water.

Abstract: Articles of manufacture are disclosed for the controlled delivery of pest controlling substances. Methods for producing such articles and utilizing them in pest control programs are also described. Laminated articles are provided which comprise one or more layers containing active pest control and pest attractant substances and which allow the controlled release of the pest controlling substance from within the laminate to the surface of the laminate so as to maximize efficiency against target species in the surrounding environment. The laminated structure also permits prolonged, controlled release of pest controlling substances and properly timed combinations of such substances that might otherwise be prematurely dissipated, decomposed or inefficiently applied. Various combinations of polymers materials and active agents and a number of different laminated structures are utilized to optimize efficient use of the pest controlling substance against a variety of target species.

Abstract: A liquid insecticidal composition having enhanced insect knockdown comprising an active insecticide, a liquid medium for emulsifying, dispersing, or solubilizing the insecticide, and at least one of N-vinyl 2-pyrrolidone, N-methyl 2-pyrrolidone, and 2-pyrrolidone. The amphiphilic solvency characteristics of the 2-pyrrolidones increases the penetration of the insecticide into the body of the insect to provide enhanced insect knockdown.

Abstract: The topical preparation is utilized in treating skin disorders such as skin infections, minute insect infestations, and rashes in the skin of living creatures such as dogs, cats and sheep. One preferred embodiment of the preparation comprises a solution including the following ingredients: approximately 0.8 ounce malathion; approximately 5 ounces copper sulfate; approximately 5 ounces alum; approximately 10 ounces salt; approximately 1 ounce chloroform; approximately 3 quarts 70% alcohol solution; approximately 0.04 ounce Au Jus mix (powdered); and approximately 5 gallons of water.

Abstract: This invention describes a composition of matter and a method of treating agricultural substrates in which an active ingredient selected from the group consisting of fungicides, bactericides, insecticides, insect repellents, herbicides and plant growth regulators and mixtures thereof is utilized in conjunction with an amount of a glycoside dispersing agent selected from the group consisting of fructoside, glucoside, mannoside, galactoside, taloside, guloside, alloside, altroside, idoside, arabinsode, xyloside, lyxoside and riboside and mixtures thereof which is sufficient to form an emulsion or dispersion of the active ingredient.
