  • Mollusc repellent
    Patent number: 6770674
    Abstract: A mollusc repellent, which includes a substantially insoluble metal oxalate and a suitable carrier therefor, which exhibits prolonged efficacy. The mollusc repellent is environmentally friendly, being both non-phytotoxic and harmless to non-target animals, and is therefore suitable for use in sustainable agriculture, where the use of toxic chemicals is unacceptable. The mollusc repellent can be used in the form of a solid or as a coating composition.
