Abstract
An effective, readily ingested molluscicidal bait poison includes an inert mollusc bait and two active ingredient precursors. These precursors are edible and non-toxic to terrestrial molluscs when consumed alone. However, the composition which includes the two precursors is fatally toxic to terrestrial molluscs. One precursor is a simple iron compound, while the other precursor is selected from edetic acid, its hydroxyethyl derivatives and salts of these acids. In another embodiment a single active ingredient may replace the two precursors. This active ingredient may include ferric edetate and the ferric hydroxyethyl derivative of edetic acid.
Claims10
A terrestrial mollusc stomach poison composition, comprising
- a simple iron compound selected from the group consisting of iron proteins, iron carbohydrates, and iron salts, which, alone, have little or no toxicity to the molluscs;
- a second component selected from the group consisting of edetic acid, hydroxyethyl derivative of edetic acid, or salts thereof;
- and
- an inert carrier material edible to molluscs, wherein the molar ratio of the iron in the simple iron compound to the second component is in the range of 1:0.2 to 1:2.0.
A terrestrial mollusc stomach poison composition, comprising:
- an effective amount of an active ingredient selected from the group consisting of ferric edetate and a ferric hydroxyethyl derivative of edetic acid.
