  • Nematocidally active chitin-protein complex
    Patent number: 4536207
    Abstract: A chitin-protein complex is prepared from chitin-containing biological waste material such as crustacean shells. The complex is different from both chitin and chitosan, and has useful nematostatic and nematocidal activity for agricultural and horticultural applications by admixing nematocidally effective amounts with a plant growth medium. The complex also provides a source of nitrogen in slow-release form, making it particularly suitable for combination with fertilizers, soil conditioners, etc.
