Definitions

  • the present invention relates to a molluscicidal composition, which preferably acts as zeither a stomach or a contact poison on molluscs. More particularly, the present invention while preferably being degradable is still sufficiently stable in sunlight and yet has reduced, little or no harmful effects on the environment or to non-target organisms.
  • the invention is also directed to the use of such molluscicidal compositions in killing, controlling or inactivating molluscs, in particular, snails or slugs and in also preferably providing a readily available source of iron to soil.
  • Slugs and snails are major pests of agriculture in Australia and many other parts of the world. These molluscs are able to adapt to a wide range of climatic conditions and often become established as pests in a short time. Their biology tends to favour activity in moist conditions such as habitats that are continually wet in temperate regions. However, because of their ability to hibernate in winter and aestivate in summer (i.e. seal themselves in their shell and slow their metabolism down in hot dry conditions), snails are still often found in countries with Mediterranean type climates. Slugs are able to survive in colder climates because of their ability to bury themselves in the soil.
  • Molluscs can be controlled by a combination of agricultural practices, chemical and biological agents. Chemical molluscicidal compositions can be divided into two groups,
  • stomach-action molluscicidal compositions that rely for their action on the mollusc consuming the lethal poison.
  • Methiocarb and metaldehyde are typical stomach poisons. In some situations, metaldehyde may also act as a contact poison.
  • Both contact and stomach poisons are advantageously presented for use in combination with a carrier.
  • a carrier When carriers are used as delivery for stomach poisons, it is necessary that a sufficient amount of the poison be ingested by the mollusc to ensure a lethal dose.
  • the carrier of the poison is in the form of a palatable attractant or be the attractant itself.
  • Metaldehyde is the most widely used molluscicide but it has the disadvantage that it is ineffective under cold, damp conditions. Its efficacy is dependent on high temperature and low humidity for maximum lethal effect, since if the ambient conditions are conducive, molluscs are able to rehydrate and make good the water deficit caused by the excess mucous secretion, which is stimulated by the metaldehyde, rendering the poison ineffective.
  • the second most widely used group of chemical molluscicides are the carbamates, which are anti-cholinesterase compounds.
  • Methiocarb is the most commonly used carbamate in molluscicidal compositions. Methiocarb is toxic to molluscs over a wide range of conditions and is most effective under very moist conditions. Unfortunately, methiocarb is toxic to a wide range of non-target organisms such as beneficial insects and earthworms.
  • FeEDTA ferric ethylenediaminetetraacetic acid
  • P CT/AU 98/00941 disclosed that the efficacy of metal complexone-based molluscicidal compositions can be enhanced by the incorporation of additives. These additives were shown to effectively mop up any strong chelators such as phytates, which would otherwise cheiate the metal and prevent it from acting as a poison, thereby reducing the efficacy of the composition.
  • DTPA ligand diethylenetriaminepentaacetic acid
  • metal DTPA provides a molluscicidal composition of comparable efficacy to that of compositions including either FeEDDS or FeEDTA; however, it is more biodegradable than FeEDTA (Means, Kucak and Crerar, in: "Relative Degradation Rates of NTA, EDTA and DTPA and Environmental Implications", Environmental Pollution, Series B, Vol 1 , (1980), pp 45-60) but more stable than FeEDDS (R. Takahashi, N. Fujimoto, M. Suzuki and T.
  • iron In very alkaline soils, iron is generally locked up as an insoluble hydrated iron oxide or if the soil is phosphate rich, as iron phosphate. In the form of iron oxide, the iron is virtually unavailable to plants except in high organic soils, in which the microbes act on the iron and cheiate it to make it soluble. As stated above, in citrus plantations, this iron deficiency can result in chlorosis being a serious problem.
  • FeEDDHANa Sodium ferric ethylenediamine-N,N'-bis(2- hydroxyphenylacetate), which is sold in Australia as Libfer® SP, Rexolin® and Rexiron®. This compound is fairly expensive and is usually applied to the soil as a drench, granule or powder. It degrades in sunlight to give insoluble iron oxide. The amount of FeEDDHANa needed to treat iron deficiencies is fairly large. It is common to apply 5 kg/ha once or twice a year. Other possible sources of iron for high pH soils are ferric glucoheptonate, ferric humate and ferric lignosulfonate. These compounds are cheaper and are potentially superior sources of iron.
  • the present inventor has established through a series of trials that they are not repulsive to snails and can be combined with Ferric EDTA or Ferric DTPA to provide a dual purpose product that will kill snails and be a good source of nutritional iron in high pH soils.

  • DTPA diethylenetriaminepentaacetate
  • the metal of the metal complexone is selected from the group consisting of Group 2 metals, transition metals or Group 13 metals, or mixtures thereof. More preferably, the metal is a transition metal. Most preferably, the metal is selected from iron(ll) or iron(lll), copper, aluminium or zinc, or mixtures thereof. In a further most preferred composition, the metal is iron(lll). Typically, for FeDTPA, the amount of iron required for efficacy is between about 0.4-0.8 wt. % of the total composition.
  • the molluscicidal composition is selected from the group of stomach-action molluscicidal compositions or contact-action molluscicidal compositions. More preferably, the composition is in the form of a stomach-action composition.
  • the carrier is in a liquid or a non-liquid form. More preferably, the carrier is in a non-liquid form and for a stomach-action composition, the carrier preferably includes an attractant, and preferably one that is palatable thereby yielding an edible bait to the mollusc.
  • the attractant is preferably selected from a mollusc food, such as a cereal, wheat flour, arrowroot or rice flour, bran, carrot, beer, rice hulls, comminuted cuttle fish, starch or gelatin, or mixtures thereof.
  • Other carriers of interest include polymeric materials, pumice, carbon and those materials commonly used as carriers in insecticides. Carriers may also be in a liquid form which enable the composition to be applied moist or wet.
  • the carrier may be any suitable solvent in which the metal complexone is miscible or immiscible to enable it to be spray- applied either as a solution or poured on the target area as a suspension.
  • the composition or the carrier itself may include other additives known in the art such as mollusc phagostimulants, for example, sucrose or molasses; lubricants, such as calcium or magnesium stearate, talc or silica; binders which are suitably waterproof, such as a fatty acid alcohol; fungicides and a bittering agent. Any bittering agent is preferably BITREX® which renders the composition less attractive to non-target organisms and children.
  • the carrier may also include preservatives such as sodium benzoate, vitamin E, alpha-tocopherol, 4-nitrophenol, ascorbic acid, methyl paraben, propyl paraben or sodium bisulfite.
  • preservatives such as sodium benzoate, vitamin E, alpha-tocopherol, 4-nitrophenol, ascorbic acid, methyl paraben, propyl paraben or sodium bisulfite.

  • the composition of the present invention further includes an additive that enhances the lethal activity of the composition. It has been determined that the increase in lethal activity results from the improved absorption of the toxic metal ion.
