Abstract
An ingestible mollusc poison contains a simple metal compound, an activity enhancing additive such as ethylene diamine disuccinic acid (EDDS) and derivatives thereof, and a carrier material edible to molluscs. In one embodiment the active agent of the mollusc poison may be in the form of a metal complex of EDDS. The composition may be used alone or in conjunction with molluscicidal co-active agents and/or fertilizers.
Claims22
A mollusc stomach poison composition, comprising:
- a simple metal compound, including metals selected from the group consisting of iron, copper, zinc, aluminum and mixtures thereof;
- an activity enhancing additive selected from the group consisting of ethylene diamine disuccinic acid, isomers of ethylene diamine disuccinic acid, salts of ethylene diamine disuccinic acid, metal complexes of ethylene diamine disuccinic acid and mixtures thereof;
- and
- a carrier material edible to molluscs, the mollusc stomach poison being effective to kill molluscs upon ingestion by molluscs.
A method of exterminating unwanted mollusc pests, comprising the steps of:
- providing a molluscicidal composition including
- a simple metal compound, including metals selected from the group consisting of iron, copper, zinc or aluminum and mixtures thereof, an activity enhancing additive selected from the group consisting of ethylene diamine disuccinic acid, isomers of ethylene diamine disuccinic
- acid, salts of ethylene diamine disuccinic acid, metal complexes of ethylene diamine disuccinic acid and mixtures thereof, and a carrier material edible to molluscs;
- applying the molluscicidal composition to an area infested with molluscs;
- and allowing the molluscs to ingest the molluscicidal composition.
A method of exterminating unwanted mollusc pests, comprising the steps of:
- providing a molluscicdal composition including
- a metal compound selected from the group consisting of ferric ethylene diamine disuccinic acid, ferrous ethylene diamine disuccinic acid, copper ethylene diamine disuccinic acid, zinc ethylene diamine disuccinic acid, aluminum ethylene diamine disuccinic acid, and mixtures thereof, and
- a carrier material edible to molluscs;
- applying the molluscicidal composition to an area infested with molluscs;
- and allowing the molluscs to ingest the molluscicidal composition.
An ingestible molluscicidal composition, comprising:
- a metal compound selected from the group consisting of ferric ethylene diamine disuccinic acid, ferrous ethylene diamine disuccinic acid, copper ethylene diamine disuccinic acid, zinc ethylene diamine disuccinic acid, aluminum ethylene diamine disuccinic acid, and mixtures thereof;
- and
- a carrier material edible to molluscs.
