INSECTICIDE COMPOSITION AND PACKAGE FOR COMPOSITION CONTENT Russian patent published in 1998 - IPC

FIELD: agriculture, insecticides. SUBSTANCE: invention relates to pyrethroid insecticides. Invention proposes insecticide composition based on synthetic pyrethroid and containing solvent and at least one surface-active substance. Composition has additionally thickening agent - solid substance insoluble in organic solvent and mixing with emulsifier leading to formation of triple mixture with solvent and emulsifier. Emulsifier is a surface-active substance taken from group containing anionogenic, cationogenic, nonionogenic, amphotheric surface-active substances and their mixtures and froth breaker. The latter is a substance taken from group containing polydialkylsilanes, hydrocarbon oil, tetramethyldecindiol, dimethylactidinol and acidifying agent. The latter is a substance taken from group containing acetic acid, phosphoric acid, sulfuric acid, hydrochloric acid, phosphine surface-active substances and antioxidant. The latter is a butylated hydroxytoluene or butylated hydroxyanisole. Solvent: organic solvent taken from group containing liquid alkyl-substituted aromatic hydrocarbons with 6-12 carbon, butyrol lactone, N-alkylpyrrolidone, saturated and nonsaturated aliphatic acids with 6-18 carbon atoms, salicylic acid, anthranilic acid, alkyl and alkenyl esters with 1-8 carbon atoms in alcoholic moiety, aliphatic or aromatic or heterocyclic substituted alcohols, lactones, amides. Composition is placed into package made as a packet which is made of partially hydrolyzed polyvinyl acetate at hydrolyzation degree from 70 to 90%. EFFECT: improved quality of composition. 13 cl
