00 @0 0 5* 00 Device for the transcuticular application of active substances to plants The invention relates to a device for the transcuticular application of metered quantities of systemic active substances to plants and processes for the preparation and use thereof.
In the field of plant protection, it is known to apply active substances to the plants by spraying or dusting onto the plants preparations which contain the active substances. The active substance acts either by direct contact or systemically, i.e.
15 it is absorbed by the plant through the cuticles of the leaves.
The methods used hitherto have some serious disadvantages.
On the one hand, there is a clear imbalance between 20 the quantity of active substance required on or in the plant to achieve a positive effect and the quantity of active substance actually applied by spraying or dusting.
25 On the other hand, the application of plant-protecting substances by spraying or dusting requires certain precautions to prevent damage to the health of anyone present, which cannot always be adhered to particularly in the case of houseplants and horticulture. The storage of large quantities of concentrated active substances constitutes an additional hazard. Moreover, the user, particularly at a domestic or horticultural level, generally finds it impossible to meter the active substance accurately onto the plant This does not mean the preparing of a solution from a concentrate -2containing the active substance but the actual quantity of solution which is sprayed onto the plant. In most cases too much or too little solution is sprayed on. Indoor spraying has the further isadvantage that the immediate area surrounding the plant will also be sprayed with active, substance and consequently the plants should ideally be treated in the open. Any unused residues of solution which have dried to a crust may cause problems if they cannot be disposed of properly.
A further problem when spraying or dusting is the problem of drifting. In many cases it is undesirable that neighbouring plants should come into contact with the active substance. This is the case, for example, if S vegetables or fruits ready for harvesting are in the vicinity. It is particularly undesirable for drifting to occur when using systemically acting herbicides, e.g. for combating couch grass.
A further disadvantage of previous forms of application is that after the plant protecting substances have been applied it is no longer readily possible to tell which active substance has been used to treat the plant.
o o~o S The aim of this invention is to provide a device which improves the ratio S. of active substance required to active substance applied in the field of S plant protection.
A further object is to propose a device which will increase safety when S dealing with active substances in the field of plant protection.
According to a first embodiment of the invention there is provided a device for the transcuticular application of systemic active substances to plants in the form of an active substance carrier, one surface of the active substance carrier being adapted to contact the surface of the plant so that the active substance is released into the plant, and said device having a defined reservoir area in which the active substance is retained so that a pre-determined amount of active ingredient can be applied.
According to a second embodiment of this invention there is provided a method of treating plants with a systemic active substance, wherein the active substance is retained in a defined reservoir area so that a T-e o 3 -3pre-determined amount of active ingredient is applied by the transcuticular route using an active substance carrier, through a surface of the active substance carrier adapted to contact the surface of the plant.
According to a third embodiment of this invention there is provided a method of producing a device wherein the active substance is dissolved together with a polymer, poured out to form a film and the solvent is removed, the device being optionally provided with a backing layer and/or an adhesive layer.
According to the invention the device is brought into close contact with 0' the plant so that the active substance passes through the cuticle of the leaf or stalk into the plant and is there distributed through the plant by the plant metabolism.
i In its simplest embodiment the device according to the invention consists of a carrier which stores the active substance (Fig. 1).
Suitable carrier materials are those which are capable of storing the active substance in dissolved, suspended or solid form, such as paper, textile fibres, inorganic porous materials such as silicates or carbonates (optionally mixed with binders) or polymers. Paper and polymers are the preferred carrier materials.
20 The active subs+. .e carrier also comprises means for attachment to the plant. These may be mechanical fastenings, e.g. in the form of clips or bandages, or an adhesive fastening, the adhesive fastening being preferred owing to its ease of application. It is important that intimate contact is established between the plant and the device so that the active substance passes into the plant.
In one particular embodiment the underside of the carrier may comprise microfine fibres which penetrate into the outer layer of cells and thus improve the uptake of active substance.
OlOv v 0
S*
-4- In another embodiment the underside of the carrier is coated with the active substance in microcrystalline form.
In another embodiment the upper side, i.e. the side facing away from the plant, of the active substance carrier is impregnated to make it water repellent, which ensures that highly water-soluble active substances cannot be washed out. The impregnation may be effected, for example, by spraying on suitable solutions known in the art.
In a particular embodiment the device according to the invention comprises a carrier made of a 15 self-adhesive polymer containing the active substance.
Polymers of suitable composition and glass temperature are known in the art. To improve the handling of such a carrier it is advantageous if the upper side of the carrier is coated with a non-stick 20 material.
A preferred embodiment of the device according to the invention is of laminate-like construction.
The device illustrated in Figure 2, for example, 25 consists of a backing layer, a reservoir of active substance consisting of one or more layers, an adhesive layer and a removable protective layer.
The backing layer, optionally impermeable to the 30 active substance, closes off the structure of the laminates on the side which is facing away from the plant. Suitable materials for forming the backing layer are polymers such as PVC or thin metal films, e.g. aluminium, optionally coated with a thin polymer film. If desired, the backing layer may be coloured so that the device is clearly visible on the plant. In another embodiment the 5 backing layer may be constructed, e.g. by means of a metal insert or textile insert, so that it acts as a support layer for stabilising the laminate.
In a particular embodiment the backing layer has a larger surface area than the reservoir to which it is attached and is coated on its underside with an adhesive material. In this way it simultaneously serves to fix the store of active substance to the plant. Obviously, in this embodiment, the separate adhesive layer as shown in Fig. 2 is not required.
Adjoining the backing layer is the reservoir of 15 active substance. This may consist of one or more gig• layers, although not all the layers need contain active substance.
ooo multi-layer reservoir with layers of different G e 20 active substances permits storage of combinations of active substances. The layers may contain agents which accelerate or delay the release of the active substance. Membrane-like layers are suitable for controlling the release of active substance.
Materials which are suitable for forming the reservoir containing the active substance are those which will store the active substance in solid, liquid 60 or dissolved form and release it to the plant under 30 controlled conditions.
The active substance may be embedded in the form of microcapsules in a polymer or may be present dispersed in the matrix of the polymer. It is also possible for the reservoir to form a cavity which contains the active substance in liquid form), 6 Suitable polymers for forming the active substance carrier or the reservoir layer include, for example, polyvinyl alcohol, polyvinyl acetate, plasticised polyvinyl chloride, plasticised polyamide, gelatine, waxes, polysaccharides, polymers of monoesters of olefinic acids, e.g. acrylic acid and methacrylic acid, polyhydroxyalkylacrylates and silicone rubbers.
Emulsion polymers such as PVC, polylactides, polystyrene, polyvinyl acetate, polybutadiene, polyacrylonitrile, polyvinyl esters, polyvinyl ethers and copolymers thereof are particularly preferred.
Emulsion-polymerised copolymers of the methyl and/or 15 ethyl esters of acrylic and methacrylic acid are especially preferred.
Fillers such as silica, for example, may be added to the polymers.
Adjoining the active substance reservoir is an adhesive layer. Self-adhesive polymers are well known in the art. By a suitable choice of polymers the composition of the adhesive layer may be chosen so that it controls the rate of release of the active substance from the reservoir layer. As well as adhesive layers extending over the entire surface it is also possible to have adhesive surfaces using rings or dots of adhesive. Adhesive surfaces S 30 extending over the entire area must of course be permeable to the active substance. This adhesive layer may be omitted if, for example, the active substance re3ervoir consists of a self-adhesive polymer or the enlarged backing layer also has, on its underside, an adhesive layer which extends beyond the layer of active substance.

7 For protection, the reservoir of active substance desirably possesses a removable protective film covering the adhesive layer; alternatively the entire reservoir of active substance may be present in a sachet which can be torn open. This is oarticularly to be recommended if the active substances involved are highly volatile.
In another embodiment, the device according to the invention is in the form of a sticker or label.
The outside (back) of the device is constructed so that it can be written on, e.g. it is made of a paper-based material or a polymer film which can be written on. Important information such 15 as the date of application to the plant, etc., can be written on the back.
It is also possible to print important information such as the name of the active substance used, 20 storage dates or the duration of activity of the device from the date of application, during the actual manufacture of the device. Other markings, e.g. colour codes or graphic symbols, may also readily be printed or stamped on the back of the 25 device.
This provides, for the first time, a plant protecting system which will enable anyone to tell which active substance has been used on the plant, even after the substance has been applied, without any additional tests being required.
The device according to the invention is suitable for transcuticular application of metered quantities of active substance to plants of all genera, particularly house and garden plants.
r 8 Conveniently, it is applied to the leaves or stems of the plants so that intimate contact is maintained between the plant and the device and the active substance passes out of the reservoir and penetrates into the plant.
The transcuticular application of fungicidal and/or insecticidal active substances may be used to combat or ward off pests. The device according to the invention is particularly suitable for herbicidal treatment of individual plants. Suitable active substances in terms of the invention are those compounds which have a fungicidal, herbicidal, insecticidal and/or acaricidal activity on the basis of their systemic effect. However, they also include compounds which serve as plant nutrients in the wider sense of the term, e.g. trace elements and fertilisers.
In special cases, growth accelerators or growth inhibitors or compounds which influence the speed of ripening of fruits may also be applied.
The tables list the preferred active substances which may be applied either singly or in combination in the device according to the invention.

11 The device according to the invention may contain the active substance in amounts between 10-6 and 200 mg, preferably 0.01-100,mg per device. The exact dosage depends on various parameters such as the nature of the polymer, the nature of the active substance carrier, the intended period of application, the thickness of the reservoir layer, and can be determined by simple experiments. Using the precisely predetermined quantity of active substance in the device it is possible even for non-experts to apply the required quantity of active substance to achieve the desired effect without over- or e0S under-dosing. This is not always guaranteed by simply spraying or dusting.
The size of the area of contact of the device is not critical but should be such that it does not extend beyond the part of the plant to which it is applied 2 and normally ranges from 1 to 20 cm The thickness 20 of the device depends on the materials used, the layer structure, the quantity of active substance per unit area and the quantity of active substance which is intended to be delivered per unit time.
It is generally between 5 microns and 200 microns, preferably up to 100 microns, and can easily be o. determined by experiment.
Numerous advantages arise from using the device according to the invention for the transcuticular application of systemic active substances to combat pests.
The active substances are fixed on the plant over a closely defined area in an outwardly "sealed" reservoir and not, as would be unavoidable when spraying or dusting, uniformly distributed through the immediate vicinity of the plant. Accidental 12 contact with the active substance is virtually eliminated. No protective precautions breathing apparatus) are required when applying the substances.
At the end of the treatment any unused residues of active substance can be disposed of relatively easily by removing the reservoir of active substance and discarding in the usual way. Useful insects bees) are not endangered either during application of the active substance or during the period of treatment.
The active substance can be protected from external influences, such as UV radiation or washing away by rain, by being contained in the active substance reservoir.
15 Consequently, preventive long-term treatment of the plants is substantially less problematic than 00 S s. with conventional methods. It is also easier to use less robust active substances.
20 The quantity of active substance actually applied coo is drastically reduced compared with that used for dusting or spraying. Accidental contact with the active substance and even direct contact e*o with the active substance layer is not dangerous, compared with conventional preparations, owing to the fact that the active substance is relatively 0 0g0 strongly fixed in the reservoir.
The device according to the invention may be produced, for example, by the following methods.
The active substance is dissolved or suspended together with the polymer and any additives used in a volatile organic solvent, then poured out to produce a film of predetermined thickness and dried. The reservoir of active substance thus obtained can subsequently be provided with a backing layer, an adhesive layer and a protective coating r 13

If the carrier material consists of an absorbent material such as paper, the active substance reservoir can be produced by simply saturating with a solution of the active substance; this may be done, for example, by immersi n or spraying.
The active substance may also be printed onto the carrier material using known printing methods, e.g. on a polymer or preferably on paper.
A carrier paper) charged with active substance may be provided with a backing layer which is sticky 15 on the ulderside. After a removable protective film has been applied, the resulting laminate is cut to the required size.
In another embodiment the active substance carrier 20 is fixed to the plant by means of an adhesive covering plaster.
Active substance reservoirs having a fine crystalline layer of active substance on their underside may 25 be prepared by simply applying the fine crystalline active substance to a sticky carrier material.
The invention is illustrated by means of the following Examples. Eudragit is a Trade Mark.

0 <4 The device is applied by simply pressing it: a) onto the top of the leaf in the lowest leaf area; b) onto the underside of the leaf in the lowest leaf area; c) onto the stalk or petiole.
For the first test batch using Vicia plants a single reservoir was applied to each plant or leaf. In the second test batch on ornamental plants, 1 4 reservoirs were applied per plant or petiole.
16 Infestation with Aphis fabae was then achieved, after application of the device, by means of small dishes containing about 50 aphids, always on the uppermost leaf area, and accordingly on the other, untreated, side of the leaf. Where the active substance had been applied to the stem, infestation was carried out on the top layer of leaves (see Fig. The results were evaluated by counting the number of aphids dead and alive (given as mortality, i.e. activity of the active substance) for Vicia after 1, 2 and in some cases 4 days.
For the second test on ornamental plants, the results o were evaluated 7 days after application.
15 2. Results S The test results from the first test on Vicia plants are shown in Table 3. These results show that dimethoate develops a translaminar and a systemic see 20 activity when applied by this method. The activity 0*s° depends on the dosage.
It is also found that the highest activity rates are achieved when the substances are applied to the stem. The plant tolerance depends on the dosage and site of application, the latter being the critical f ator. For example, at points where the dimethoate is rapidly transported away by the plant metabolism, namely the stem, no phytotoxicity is observed even at the higher dosage.
