Description

NOVEL METHODS OF DELIVERING ACTIVE INGREDIENTS TO PLANTS
This invention relates to bandages or wound dressings for plants. More especially, the invention relates to the delivery of active ingredients to plants and to the repair of damaged, spliced or grafted plants in which both healing materials and mechanical support are brought to the site of the wound, splice or graft by means of a water-soluble or water-dispersible bandage or wound dressing, in particular, but not exclusively, a water-soluble or water-dispersible self adhesive tape or label.
It has long been known that when a plant is grafted or spliced, nature must be helped by means of a cord which is wrapped around the site of the graft or splice in a similar way to whipping the end of a rope. Similarly, when a plant has been -damaged mechanically by external forces, for example by wind, or by human or animal interference, the value of the plant may be such that a repair is undertaken. This repair may take the form of a splint which is applied to the affected part of the plant or a piece of cord which is tied between the damaged part of the plant and an undamaged part in order to support the damaged part whilst nature is allowed to complete the healing process. According to the present invention there is provided a bandage or wound dressing for application to the tissue of trees, shrubs or other types of plant or cut plant wherein the bandage or wound dressing comprises a water-soluble or water-dispersible ■ filmic substrate and a water-soluble or water- dispersible pressure sensitive adhesive into either or both of which one or more active ingredients are incorporated.
The terms "water-soluble", "water-dispersible" and "cut plant" as they are used in the description of this invention and in the claims are defined as follows:
The term "water soluble" refers to materials that are capable of being dissolved in water of whatever temperature to form a homogeneous solution.
The term "water dispersible" refers to materials that are capable of being dispersed in water of whatever temperature to form a permanent or temporary suspension.
The term "cut plant" means any plant that is cut for subsequent sale or re-use including therefore flowers, ornamentals and shrubs, certain vegetables such as lettuce, and certain- fruit such as bananas, pineapples, although these examples are by no means limiting. As will be appreciated, the water soluble and water dispersible materials described and claimed herein require the presence of water to dissolve/disperse the material .
In contrast, biodegradable materials are materials that are capable of being broken down safely by living micro-organisms, principally bacteria and fungi, into innocuous products (e.g. the raw materials of nature) and disappear into the environment. This is a totally different process and the presence of water is not always necessary for a material to biodegrade. The present invention excludes materials that are biodegradable
Preferably, the bandage or wound dressing provides mechanical support to the plant during a healing process.
Preferably, the active ingredient (s) assist the healing process.
Preferably, the active ingredient (s) protect the plant during the healing process.
In a first embodiment of the invention, the bandage preferably comprises a self-adhesive tape, preferably self-wound for ease of use, or label in which the filmic substrate and pressure sensitive adhesive are formulated so that they are both fully soluble in water of a pre-determined temperature range, whether in cold water i.e. between 5-300C, in warm water i.e. between 30-600C, or in hot water i.e. not less than 600C. It has been found that such a water-soluble self-adhesive tape or label may be used in place of cord to provide mechanical support to damaged plants with a corresponding saving in time and therefore money. The degree of mechanical support may be varied by adjusting the formulation, thickness and elasticity of the filmic substrate, or by adjusting the formulation of the pressure sensitive adhesive, or by adjusting the formulation of both filmic substrate and pressure sensitive adhesive.
In this first embodiment of the invention, it is not intended that the self-adhesive tape or label comprising the filmic substrate which has been coated with the pressure sensitive adhesive will require to be subsequently removed from the plant as, over a period of time, it will either be absorbed into the plant without detrimental effects, or will be dissolved by the combined effects of rain and dew. The time taken for the self-adhesive tape or label to dissolve may be varied by selecting an appropriate grade of filmic substrate and an appropriate formulation of pressure sensitive adhesive. It will be appreciated that the selection of suitable materials will be influenced by the weather conditions to which the plant is exposed. The self-adhesive tape or label may be designed to incorporate active ingredients known to assist in the healing process whether directly as in the case of fungicides, bactericides, mouldicides, disinfectants, biocides, plant stimulants, micro- nutrients, and foliar fertilisers, or indirectly as in the case of insecticides which protect the plant during the healing process from unwanted insect attack, molluscicides which protect the plant during the healing process from unwanted mollusc attack, and plant growth regulators .
One or more active ingredients of any of the above types may be incorporated on their own or in combination either into the filmic substrate or into the pressure sensitive adhesive formulation, or into both. Different active ingredients may be incorporated into the filmic substrate and the pressure sensitive adhesive. Once the filmic substrate has been coated with pressure sensitive adhesive, the resulting material is converted either into self-wound tape or into self-adhesive labels attached to a release liner.
It will, of course, be seen that if the active ingredients are incorporated particularly into the pressure sensitive adhesive formulation which is then placed in direct contact with any part of the plant but typically the bark, one or more stems or one or more leaves of the plant, then the self- adhesive tape or label can deliver active ingredients to the plant in a similar way that a nicotine patch delivers small doses of nicotine through the skin of the human body over a pre¬ determined period of time. The benefits of this will be greater in the case where the active ingredients are systemic in nature and will therefore be subsequently transported throughout the plant. In cases where rapid uptake of active ingredient is required, the stem of the plant may be partially scarified or cut away by any means before attaching the self adhesive tape or label to, or within, the open wound in order to induce faster uptake of active ingredient.
The first embodiment of the invention is therefore able to provide, if both are required, a self- adhesive bandage or wound dressing for repairing a damaged plant from a mechanical standpoint and a novel delivery system for dispensing active ingredients to the plant, whether to help to heal the site of the wound, splice or graft, or for other reasons. It will be noticed that the delivery of active ingredients to the plant in this way is particularly safe and efficacious as the active ingredients are placed in intimate contact with the tissue of the plant without contamination of the environment surrounding the plant or the user.
In a further application of the first embodiment, the stems of cut plants or cuttings are bound, either individually or in bunches, with a self- adhesive tape or label incorporating one or more active ingredients in order to prolong their life after cutting, firstly in transport from the grower to the consumer and secondly after being placed in water by the consumer.
Similarly, the post harvest life of fresh produce may be prolonged by protecting its cut surfaces, particularly against fungal attack, by means of a self-adhesive tape or label according to the invention placed over the cut surface as quickly as possible after harvesting. Examples of such fresh produce are certain vegetables such as lettuce and certain fruit such as bananas and pineapples although these examples are by no means limiting.
It will be evident that one or both of the filmic substrate and the pressure sensitive adhesive can be coloured within their mass and the filmic substrate may be printed, in order to camouflage the presence of the tape or label on the plant and to enable marketing and technical information to be provided to the user.
In another embodiment of the present invention which is not related to a healing process, one or more herbicides are incorporated into a bandage or wound dressing, for example a self-adhesive water-soluble tape or label, preferably into the formulation of the pressure sensitive adhesive, for application to one or more leaves or stems of the plant. In this way, the herbicide or combination of herbicides is absorbed into the plant and unwanted plants can thereby be eliminated.
As will now be understood, the present invention provides a method of applying active ingredients to plants in which the active ingredient or ingredients are transmitted safely and efficaciously to the plant without contaminating the user, the environment, neighbouring plants or crops, and the self-adhesive tape or label will over time dissolve, become absorbed by the plant, or disperse either whilst still attached to the plant or in a subsequent composting process.
