Insecticide mixtures containing fatty acids

Abstract From the Canadian patent

Mixtures of organic insecticides of the organochlorine type or of selected 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 organochlorine or organophosphate or carbamate to fatty acid can range from about 1:1 to about 1:200 respectively. The, amounts of the organochlorine organophosphate or carbamate required for substantial effectiveness can be reduced significantly by concurrent use of the fatty acid. The fatty acid is more environmentally …
