Description
EDTA ferric sodium salt is the ferric sodium salt of EDTA (Ethylene Diamine Tetraacetic Acid). It is a broad-spectrum molluscicide that is capable of killing snails and slugs and protecting agricultural crops and garden plants. In particular, it can eliminate infestations of Cornu aspersum, the common garden snail. It takes effect through interacting with and destroying hemocyanin, a copper based compound existing in the blood of molluscs and anthropods that is engaged in carrying oxygen (play a similar role with hemoglobin invertebrates). It is capable of killing snails and slugs in a few days. It can also be used as a food fortifier and a source of iron to be supplemented to the foods for nutrition purposes.
