Description
SPECIFICATION
Means for killing slugs
This invention relates to means for killing slugs, in particular to absorbent substrates coated with molluscicidal compositions. Molluscs, in particular slugs such as Agriolimax reticuiatus are voracious devourers of vegetable matter and cause considerable damage in gardens and smallholdings. In BP. 991939 there is described a method of combating snails of the genera
Oncomeliana, Australorbis, Bulinus and Lymnaea by means of diphenyl methylamine derivatives and compositions containing them. The derivatives are to be used principally in aquatic habitats of the snails but it is mentioned, inter alia, that an absorbent carrier such as porous tiles, clay granules or fibrous material such as paper or cloth may be impregnated with the derivatives.
We have found that an absorbent substrate which is water-repellent on one side provides an attractive habitat for terrestrial molluscs when laid on the ground with the water-repellant side uppermost and that such a substrate when coated on the non-water-repellent side with a molluscicide composition and laid this side down on the ground provides a very efficient means of combating terrestrial molluscs.
Accordingly, the present invention provides means for combating terrestrial molluscs, in particular slugs, comprising an absorbent substrate which is water-repellent on one side and has on the other side a coating of a molluscicide composition.
The absorbent substrate may be rigid, for example, paper board or a porous ceramic tile or a shallow dish of similar material the concave side of which is coated with molluscicide composition. Usually the ground on which the tile or dish is placed is sufficiently uneven for slugs to burrow between the surface of the ground and the underface of the tile or dish.
However, the rim of the dish may be notched to provide easy access for slugs to the underside and similarly, the tile may be provided with projections on the molluscicide-coated face to hold it slightly clear of the ground. Alternatively, the substrate may be flexible for example cloth, foamed plastics or, in particular, paper sheet. Paper of any size or colour can be used, although green is preferred for aesthetic reasons. T he sheet may be designed to be placed under vegetables or fruit, e.g. marrows and strawberries, in the field or garden, the vegetable or fruit being laid on the waterproofed upper surface.The water-repellent surface protects the substrate and the coating of molluscicide composition from rain and in addition it helps maintain humidity between the underside of the substrate and the ground on which it is laid, particularly when it is also relatively impervious to water vapour. Slugs congregate under the substrate where humidity is high and they are poisoned through feeding on, and through contact of the foot with, the molluscicide-coated surface.
For application under individual plants the substrate, e.g. paper or ceramic, may be in the form of discs which may be placed under the plant. Conveniently, the disc may have a diameter of about 20 to 30 cm the central portion of about 3 to 5 cm diameter being removed, and being provided with a slit, e.g. a radial slit, connecting the circumference with the resulting hole so that the disc may readily be positioned around the stem of the plant.
Coated water-repellent paper may also be provided in the form of a roll which may be unwound and used to provide a continuous barrier along a row in vegetable garden or small holding. In use, the strip of paper may be weighted down by stones or earth to prevent it being blown away. A waterproofed paper known as Labcoat" or "Benclicote" is particularly suitable for use in this invention. This is an absorbent paper backed with thin polythene film which is not only water repellent but which is also relatively impervious to water vapour.
Examples of molluscicides which can be used in the molluscicidal compositions are metaldehyde, copper salts, 4(methylthio) - 3, 5-xylyl methylcarbamate, 1 N methylcarbamate, S2cyanoethyl-N-[(methylcarbamoyl)oxy3 thioacetimidate and nicotinanilide. Suitable copper molluscicides are inorganic copper salts, for example copper sulphate and organic salts, for example copper dimethyl dithiocarbamate.
The rate of application of molluscicide on the surface of the porous substrate will of course, depend on the effectiveness of the particular molluscicide used. For metaldehyde, a rate of application of from 30 gms to 40 gms per square metre of substrate is generally satisfactory, but simple tests will readily indicate the optimum proportion of metaldehyde or other molluscicide to use in particular compositions and in particular circumstances.
The molluscicide is applied to the surface of the substrate in the form of a composition comprising a solid binder such as gelatine, starch, synthetic or natural resins or gums, e.g.
carbomethoxy methyl cellulose and tragacanth, or clay. Of these gelatine is preferred since the gelatine in the coating of molluscicide composition not only acts as a binder but also absorbs water when the substrate is laid on the ground. When the substrate is paper, the water-swollen gelatine helps weight the paper down. The attractiveness of the coated substrate may also be enhanced by incorporating in the molluscicide composition, an attractant for slugs, a farinaceous material, such as bran, and vitamin B's being very suitable materials for this purpose. A suitable rate of application to paper of molluscicide composition is preferably from 750 to 1 250 gms per square metre.
A suitable thickness of coating on the substrate is from 0.5 to 1.5 mm. We have also found that since molluscs attracted to the coated substrate crawl over the molluscicide-coated underside the effectiveness of the coated substrate can be improved by incorporating in the molluscicide composition coating an activator which will promote intake of the molluscicide through the foot of the mollusc.
The molluscicide, and activator if used, may be present in the molluscicide composition in any suitable proportion, the value of which together with a suitable rate of application of the composition, being determinable by simple tests. For example, using metaldehyde, a proportion of from 3 to 4% by weight of the composition is suitable, depending on the weight of the coating applied. When an activator is used a satisfactory "kill" is possible even when the proportion of molluscicide is reduced by from 25 to 50% e.g. to 2.0 to 2.5% of metaldehyde applied at 20-25 gms per square metre.
Useful activators for the composition are enzymes and proteins which can stimulate endocytosis or pinocytosis in the epithelial cells of the foot of the mollusc. Suitable activators are substances which induce pinocytosis in Amoeba, see for example the paper by C. Chapman
Andresen in Compte. rend Lab. Carlsberg 33, 73-264 (1962). A test for pinocytosis is described by W. Strauss in J. Biophysic and Biochem. Cytol. 5 No. 2 1 93 (1959) and this test may be used to identify enzymes and proteins suitable for use as activators in this invention.
Suitable activators include ribonuclease, blood albumin, bovine serum albumin, horse radish peroxidase, egg albumen and enzyme PFC (an enzyme waste from A.B.M. Chemicals).
The proportion of the enzyme or protein activator may be from 0.5% to 10% by weight of the composition.
Alternatively, the effectiveness of the molluscicide may be improved by incorporating in the composition, as an activator, a surface active agent. Suitable agents include non-ionic agents, such as condensation products of polyalkylene oxide and alkylphenols and fatty acid esters of polyoxy alkylenes, cationic agents such as quaternary ammonium salts, e.g. cetyltrimethylammonium chloride, cetylpiridinium chloride and anionic agents such as sodium salts of secondary long chain alkyl sulphates e.g. sodium lauryl sulphate, salts of alkyl aryl sulphates, sodium deoxycholate, sodium taurocholate and sodium tauroglycocholate (TGC).
Suitable proportions of surface active agent in the composition range from 0.1 to 1% by weight depending on the type of agent. In the case of sodium tauroglycocholate and sodium lauryl sulphate 0.2 to 0.4% by weight is very suitable. In the case of sodium acetate, a very suitable proportion is from 1.5 to 3% by weight of the composition.
Sodium acetate may also be used to induce trans-membrane uptake in the cells of the mollusc suitably in a proportion of from 1 to 5% by weight of the composition.
The absorbent substrate may be made suitably water-repellent by applying to it any water repellant material which does not, by its nature, also repel slugs, e.g. by its odour. Suitable water repellant materials include wax, silicones, and synthetic polymers. Alternatively, the substrate may be waterproofed by bonding to it a thin film of polymer such as polythene, polyester or p.v.c. which also substantially reduces passage of water vapour through the substrate. As a further alternative for a substrate which is a porous ceramic tile, dish or the like, the surface to be uppermost in use may be glazed.
The following examples illustrate the invention:
Example 1
An activated molluscicide composition A was prepared as follows:
Bran (26gm) was mixed with water (1 O0ml) and homogenized into a rough paste. Gelatine (38gm) was added to the warmed homogenized bran with stirring to form a thick paste. The paste was allowed to cool and 4% metaldehyde and 2% bovine serum albumin were stirred in while the gel was still viscous. The viscous gel mix was then spread (with a brush or roller) onto the absorptive surface of waterproofed paper (e.g. "Labcoat" or "Benchcote") and allowed to cool further and dry.
A similar composition "B" from which the 2% albumin was omitted was made up and applied to waterproofed paper in the same way. The procedure was repeated with composition
C, from which both the albumin and the metaldehyde were omitted.
Sheets of so treated "Labcoat" or "Benchcote" measuring 6 x 6 ins. were laid out in the field. Test and control sheets were laid side by side. The results achieved over a seven-day period are illustrated in the Table I below:
TABLE 1
A. Paper containing bran/gel, metaldehyde and albumin
B. Paper containing bran/gel and metaldehyde only
C. Paper containing bran/gel only
A B C
DAY 1 Slugs killed 32 1 3 0
DAY 2 Slugs killed 1 7 11 0
DAY 3 Slugs killed 11 4 0
DAY 4 Slugs killed 9 2 0
DAY 5 Slugs killed 6 1 0
DAY-6 Slugs killed 4 2 0
DAY 7 Slugs killed 4 1 0 These results show that both type A and B anti-slug paper are effective in the field buy papers containing an activator such as albumin added as a pinocytotic inducer, thus making the metaldehyde enter via the slug foot, are most efficient at killing slugs.
EXAMPLE 2
A further composition D was made up similarly to composition A of Example 1 but containing 2% metaldehyde. When applied to waterproofed paper and which was then tested as in
Example 1, the results obtained were similar to those of composition B. Similar results were also obtained when the composition D was applied to one side of a porous ceramic tile, the other side of which had been treated with wax to provide a water-repellant surface.
EXAMPLE 3 Sheets of paper 15 X > c 1 5 cm square, coated on one side with polythene film and having on the other side a coating about 1 mm thick of a gelatin-bound molluscicide composition were laid out regularly on uniform grassland and the number of dead slugs counted each morning.
