SUSTAINED RELEASE PREPARATION COMPOSITION COMPRISING INSECT PEST-TARGETING GEL COMPOSITION

摘要

PROBLEM TO BE SOLVED: To provide 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.SOLUTION: The sustained release preparation at least comprises a polymer thin tube having one sharp end and an insect pest-targeting gel composition in the polymer tube, the composition comprising at least volatile substances and an oil gelling agent, wherein the volatile substances are comprised in an amount of from 70.0 to 99.0% by mass in the insect pest-targeting composition and are released outside of the polymer thin tube through the polymer thin tube.
