Abstract

The invention is based on the problem of specifying a system for dispensing an active-ingredient fluid containing an active ingredient, in particular a plant- and/or insect-effective active ingredient, which is characterised by high controllability of active ingredient release, a simple structure and simple recyclability and reusability of its components. According to the invention, this problem is solved by a system for dispensing an active-ingredient fluid, in particular a plant- and/or insect-effective active ingredient, which comprises the following components: a) a first module, comprising an electrochemical gas development cell and a control module which controls the gassing rate of the gas generated by the gas development cell; b) a second module, which can be connected to the first module, comprising a container for the active-ingredient fluid containing the active ingredient with an active-ingredient outlet, wherein a conveying pressure built up by the gas generated by means of the gas development cell causes the active ingredient to be released at the active-ingredient outlet; and c) a third module, which can be connected to the second module, comprising an application element which provides the active ingredient provided at the active-ingredient outlet for release onto the plant and/or the insect/organism and/or into the environment.

Description

System for applying an active substance fluid, in particular a plant- and/or insect-active active substance The present invention relates to a system for applying an active substance fluid containing an active substance, in particular an active substance effective against plants and/or insects. Devices available on the market for delivering active ingredients or other conveyable substances that are used to influence the behavior of living organisms, such as pheromones to attract or confuse pests in plantations or vineyards, function either completely passively or electromechanically. Passive systems usually consist of plastic elements in which the active ingredient is incorporated or which contain the active ingredient in another form, e.g. as a liquid, and release it through evaporation or osmotically (diffusers). Electromechanical systems often include active ingredient containers (spray cans), some of which are under pressure and are then operated electromechanically. The passive diffusers follow a very simple principle, as they do not contain any mechanically moving parts. However, the potentially expensive active ingredient is released continuously, e.g. even when no active ingredient is needed, such as at certain times of the day or in certain weather conditions. In addition, many units are required per hectare of agricultural land. After the active ingredient has been released, these systems must be collected and disposed of. Another disadvantage is that the release of the active ingredient can no longer be controlled once it has been set in motion. It is also not clear whether the system still contains active ingredient and can therefore still release it. The electromechanical systems, on the other hand, are characterized by the fact that a spray can be triggered at specific intervals using an electromechanically driven element in a pressurized container. This leads to significantly fewer units required per hectare than with passive diffusers. Nevertheless, such systems have single use, there are many components that have to be disposed of or recycled. In addition, a relatively complex construction (electronics, pressure vessel, valve, actuators, etc.) is required. However, in this area of sensible active ingredient release, the active ingredient itself is often the most expensive component in all of these existing systems, so the active ingredient that is released into the environment permanently (diffusers) or at regular intervals (electromechanical systems) with these existing systems is used rather wastefully. In this way, with passive diffusers and some electromechanical systems, active ingredients are released and consumed even when they have no effect at all, for example when the pests are naturally inactive due to the prevailing weather conditions or the current time of day. The pressure vessels of the electromechanical systems are also classified as hazardous goods during transport, which means additional effort when shipping the goods. The invention is therefore based on the object of specifying a system for applying an active substance fluid containing an active substance, in particular an active substance effective against plants and/or insects, which is characterized by a high degree of controllability of the active substance release, a simple structure and easy recyclability and reusability of its components. The object is achieved according to the invention by a system for applying an active substance fluid, in particular an active substance effective on plants and/or insects, which comprises the following components: a) a first module, comprising an electrochemical gas development cell and a control module controlling the gas rate of the gas generated by the gas development cell; b) a second module connectable to the first module, comprising a container for the active substance fluid containing the active substance with an active substance outlet, wherein a delivery pressure built up by the gas generated by means of the gas development cell causes an active substance to be released to the active substance outlet; and c) a third module connectable to the second module, comprising an application element which delivers the active substance provided at the active substance outlet to the plant and/or the insect/organism and/or the environment. The electrochemical gas development cell technology used in the present invention is therefore suitable for providing a market-ready product for the targeted and active ingredient-saving release of, for example, pheromones to protect plants against pests. Due to the small size, the simple construction, the self-sufficient mode of operation and the controllability of the active ingredient release using a very simple electronic circuit, a system can be built that can release active ingredients according to definable and specifiable criteria and thus uses significantly less active ingredient and resources than existing systems. In addition, the gas d
