Abstract
A molluscicidal device in the form of a chemophysical barrier which is placed in the path of molluscs (e.g., between their habitat and an area to be protected from infestation). The device comprises a solid body, typically in the form of a sheet or continuous length strip made of a thermoplastic water-insoluble polymer in which is dispersed a molluscicidal agent. The dimensions of the body, the nature of the agent, and the concentration of the agent on the surface of the body are such as to cause any mollusc that attempts to cross the body to be immobilized, whereby it remains on the body and receives a lethal dose of the agent.
