Sustained release preparation comprising insect pest-targeting gel composition

摘要

Provided is a sustained release preparation comprising an insect pest-targeting gel composition, the preparation being free from leakage or reaction of a volatile substance and being capable of releasing the volatile substance at a constant rate. More specifically, provided is a sustained release preparation including a polymer tube and an insect pest-targeting gel composition in the polymer tube, the composition including one or more volatile substances and an oil gelling agent, wherein the volatile substances are included in an amount of from 70.0 to 99.0% by weight by the insect pest-targeting composition and are released outside of the polymer tube through the polymer tube.

主权项

1. A sustained release preparation comprising:
a polymer tube and, an insect pest-targeting gel composition in the polymer tube, the composition comprising one or more volatile substances and an oil gelling agent selected from the group consisting of a long-chain fatty acid, a polyvalent metal salt of the long chain fatty acid, a saccharide derivative and wax, and wherein the sustained release preparation does not contain a solvent, wherein said one or more volatile substances are comprised in an amount of from 70.0 to 99.0% by weight by the insect pest-targeting gel composition and are released outside of the polymer tube through the polymer tube, andwherein the long-chain fatty acid is selected from the group consisting of 2-ethylhexanoic acid, decanoic acid, lauric acid, myristic acid, stearic acid, palmitic acid, arachidic acid, behenic acid, palmitoleic acid, oleic acid, vaccenic acid, linoleic acid, linolenic acid, arachidonic acid, icosadienoic acid and erucic acid.
