    In a method of removing plants, especially neophytes. First of all, a surface area to be treated with plants to be removed is determined, and the plants to be removed and their root area in the area area are uncovered. Holes are drilled in the roots of the plants to be removed, into which an active agent containing triclopyr, a sparingly water-soluble pre-emergence herbicide and water is injected by means of a lance specifically into a single-stick treatment. This treatment is carried out during the growing season of the plant. After a few weeks, treated plants are killed. Aftertreatment can be carried out as needed. The triclopyr is the killing agent while the sparingly water-soluble pre-emergence herbicide acts as a binder. Napropamide, oxyfluorfen, dimethachlor or clomazone are suitable as sparingly water-soluble pre-emergence herbicide. The process is characterized by the targeted and economical use of the bound active agent. Environmental damage is thereby minimized. It is also claimed an active agent as such for the elimination of plants, especially neophytes.

    Technical area
    The invention relates to a method for controlling plants, in particular invasive plants and invasive neophytes such as bamboo or Japanese Knotweed. It also relates to an agent for the elimination of plants, especially neophytes.
    State of the art
    Invasive neophytes are an increasing problem in many latitudes. Neophytes are plants that have resettled in a particular geographic area over natural processes or have been accidently or deliberately settled. Certain neophytes are considered invasive to the existing flora by displacing the existing plants and thereby affecting the existing fauna. In addition, invasive neophytes are known to break and weaken embankments, masonry, road surfaces and ballast for railway tracks by their extremely strong root system and thus cause significant damage. Such neophytes are for example the Japanese potato. Bamboo is also an increasing problem in gardens, for example.At present, methods are being used in Switzerland to combat such neophytes, which are based on the application of chemicals, which, however, have been proven to contaminate river and groundwater and thus drinking water and cause disease in humans and animals. One of these chemicals contains glyphosate, which is banned in European Union countries because of its toxicity.
    Description of the invention
    The present invention is based on the task to provide a method and an active agent that allows a permanent elimination of undesirable plants, especially invasive plants and neophytes and in particular causes no health and environmental impact.
    According to the invention and according to claim 1, a method for the removal of plants comprises the following steps:a) the determination and / or marking of a surface area to be treated with plants to be removed.b) exposing the plants to be removed and their root area in the area from step a).c) drilling holes in the roots of the plants to be removed by means of a drill.d) Injection of an active agent containing triclopyr, a pre-emergence treatment herbicide which is sparingly soluble in water and water in the roots by means of a lance in the roots during the growing season of the plant, carried out in step c).
    First, in step a), the surface area to be treated is determined in order to take into account as much as possible all areas and plants to be treated while limiting the area as much as possible in order to avoid unnecessary treatment of unaffected areas. In step b), the plants to be removed are exposed by mowing surrounding non-invasive plants or removing objects. This allows the identification of the plants to be removed and of the terrestrial areas in which runners can be suspected. By root drilling in step c), the root areas of the invasive plants are exposed as deeply as possible and rhizomes are exposed through multiple holes and made accessible for treatment. Care is taken to ensure that adjacent plants that are not to be treated, are left out.In step d), the actual active agent is applied in a single-shot treatment by means of a lance, the agent is specifically injected only to the plants to be removed. The remedy is therefore not spread over a wide area, but injected only on those individual plants where it is necessary. Depending on the strength and age of the plant, the amount of the applied active agent is adjusted. The active agent used contains a mixture of triclopyr and the sparingly water-soluble pre-emergence herbicide and water, the triclopyr acting as the actual active substance for killing roots and rhizomes. It is suitable as a fast-acting substance for targeted killing of plants. The sparingly water-soluble pre-emergence herbicide acts as a stabilizer by binding triclopyr in a chemical reaction. Through this binding, the triclopyr is not washed out after injection, but retains its full effect in killing the roots with which it comes into contact.The use of triclopyr, together with the binding action of the sparingly water-soluble pre-emergence herbicide and the targeted injection of the active agent into the root and rhizome areas, results in a rapid killing of the plants, the active ingredient being used sparingly and not being washed away unnecessarily. An outflow of the active agent used is minimized as possible, so that an impairment of the groundwater can be practically excluded. This enables effective treatment that minimizes environmental damage.
    The invention has the advantage that the method allows a cost-effective and permanent elimination of neophytes. After the treatment according to the invention, post-treatments are only necessary to a limited extent. The neophytes can be removed in place without removing the soil, masonry, road surface or track surface. This means a reliable elimination within a foreseeable and relatively accurately timed period. In addition, the amount of work involved, as well as the expense of waste disposal and disposal, are enormously reduced. In comparison to a dredging, removal and disposal of the entire soil, the method according to the invention achieves a reduction of the costs by a factor of 10.
    The inventive method is suitable for elimination by killing of various plants, especially neophytes, which occur, for example, in Central Europe. The method according to the invention is used to eliminate the following plants, this list not being conclusive:Japanese Knotweed (Reynoutria japonica, also known as Fallopia japonica),Sakhalin Knotweed (Reynoutria sachalinensis),Himalayan Knotweed (Polygonum polystachyum),Bastard Knotweed (a cross between the Japanese Knotweed and Sakhalin Knotweed,which has developed in Europe.)Bamboo, hardy (Phyllostachys aurea),Bamboo of other species (e.g., pleioblastus pygamaeus distichus),Vinegar tree (Rhus typhina),other invasive plants including indigenous plants as well as neophytes such as cat's tail (Acalypha hispida).
    The application of the active agent directly to the drilled roots causes an immediate and almost complete absorption of the active agent by rhizomes, ie strong shoots, and the root wood itself. The agent does not reach the soil but is absorbed by the plant, causing them dies within weeks. The active ingredient thus does not come into contact with humans, animals or other plants that are to be maintained, leaving them intact.
    The method is preferably carried out during the growing season of the plant, since the uptake of the active agent during the growth of the plant is strongest and the inventive method is most effective. In Central European latitudes, the process is therefore preferably carried out approximately in May to October. The method is also preferably carried out in consideration of the weather and the temperatures when no heavy downpours are expected and the temperature is suitable for growth. For this purpose, a minimum soil moisture is necessary, similar to what is necessary in a fertilization. As a result, the use of the active agent can be dosed more accurately and a washing away of the active agent as possible excluded. After injection of the active agent, the treated area is shut off for a few weeks, for example 4-6 weeks, and not processed. Within this time, the active ingredient is broken down in the plant and kills them. The main plants are partially or completely killed by the first treatment.
    The concentration and dosage of triclopyr in the active agent is determined on the one hand according to the type of plant. On the other hand, the range of dosage is determined by the strength or size of the plant to be removed. Thus, a minimum dosage is determined so that the plant is killed as possible. Depending on the plant species to be eliminated, the dosage of triclopyrs is adjusted. In addition, the dosage of triclopyrs at the upper end of the range is limited so as to avoid contamination of the soil and water as possible, that is, to ensure that as much as possible of the total amount of the active agent is absorbed by the plant and does not reach the soil ,
    The triclopyr used in the process according to the invention is a triclopyr product such as, for example, triclopyr-butotyl with the CAS no. 64 700-56-7 from the group chloropyridines.
    For the sparingly water-soluble Vorauflaufherbizid a Vorauflaufherbizid is used, which is heavy, practically insoluble or slightly water-soluble with a water solubility of at most 1.1 g / liter at 20 ° C, preferably less than 0.5g / liter at 20 ° C.
    In one embodiment of the method is used for the sparingly water-soluble pre-emergence herbicide napropamide for stabilization or so-called stratification of the active ingredient triclopyr, wherein the napropamide is defined by the CAS No. 15 299-99-7.In a further embodiment of the process, for the sparingly water-soluble pre-emergence herbicide, oxyfluorfen is used as a stabilizer which binds the triclopyr in the same manner, the oxyfluorfen being defined by CAS No. 42874-03-3. It is also known, inter alia, under the IUPAC name 2-chloro-alpha, -alpha-trifluoro-p-tolyl 3 ethoxy-4-nitrophenyl ether.
    In further embodiments of the method is used for the sparingly water-soluble Vorauflaufherbizid and as a stabilizer of triclopyrs one of the active ingredients from the group containing dimethachlor with the CAS No. 50 563-36-5, Clomazone with the CAS No. 81 777-89 -1, alachlor with the CAS no. 15 972-60-8, a metolachlor, for example with the CAS no. 51 218-45-2, aclonifen with the CAS no. 74 070-46-5 and Linuron with CAS No. 330-55-2.
    The sparingly water-soluble Vorauflaufherbizid is each determined in the dosage so that a minimum amount is present to ensure the binding of triclopyr. Various dosages of napropamide and oxyfluornene are disclosed below, with dosages being the same for both napropamide and oxyfluorfen.
    In one embodiment of the method, the active agent is used in the following dosage:0.5 grams-10 grams of triclopyr and at least 1.7 grams of napropamide or oxyfluorfen each mixed in 1 liter of water.This mixture is suitable for the removal of bamboo.The dosage of napropamide or oxyfluornene as a binder is determined according to the amount of water. For 1 liter of water, napropamide or oxyfluorfen in an amount in the range of at least 1.7 grams is suitable to achieve binding of the active agent.
    In a particular embodiment of the method, the active agent for the removal of bamboo is dosed as follows:6.7 grams of triclopyr and 3.5 grams of napropamide or oxyfluorfen in 1 liter of water.
    In a further embodiment of the method, the active ingredient is metered as follows: 0.1 gram-2 grams of triclopyr and at least 1.7 grams of napropamide or oxyfluorfen mixed in 1 liter of water. This method is suitable for the removal of any Japanese potato.
    In another particular embodiment of the method, the active ingredient is dosed as follows for the removal of Japanese potato: 1.4 grams of triclopyr and 3.5 grams of napropamide or oxyfluorfen in 1 liter of water.
    In a further embodiment of the method in step b), the exposure of the plants to be removed, in addition to be removed plants cut off just above the ground. Preferably, a small part of the plant is allowed to stand so that they can be recognized as such. This makes it easier to identify which rhizomes are to be treated and which are not.
    In a further embodiment of the method, a drill or a trimmer is used in step c) as a drill. For smaller rootstocks, a drill is preferably used, for larger rootstocks or rhizomes in high density, the use of a trimmer is more advantageous. In any case, the root areas of the invasive plants are exposed as deeply as possible and rhizomes are exposed through multiple holes or millings and made accessible for treatment.In one embodiment of the method, a further step e) is carried out: a check after a predetermined time in order to identify remaining plants and non-killed shoots of the plants which are to be eliminated.
    If such plants are still present, a post-treatment is carried out by the step d) or steps c) and d) are carried out again.
    In one embodiment of the method, a lance is used with a flow meter for indicating the amount applied for injecting the active agent. This allows further optimization of the dosage and control of the amount of the injected active agent.
    Depending on the density of the plants to be removed for treatment per square meter area, in one embodiment, in each case 5 liters of one of the active substance mixtures mentioned are used.
    In order to control the application of the active agent and its effect as much as possible, the surface area determined in step a) is divided into partial areas, e.g. Squares divided and marked to control the dosage. The marker also serves to control the treated area for a period of, for example, several weeks or two months after the treatment. In the area to be treated, for example, 4-5 holes per square meter are made, each at a depth corresponding to the thickness (thickness or size) and the age of the plants. The location of the wells is also determined to provide sufficient distance from adjacent plants to be spared from the treatment.
    Preferably, after the treatment with steps a) to f) in a step e), the treated surface area is left to rest for two vegetation periods by no grave work or humusification being carried out in the area. For example, a vegetation period in the Central European region corresponds to the time between about April to about November.
    If necessary, new shoots are treated immediately in a post-treatment with tapping the roots and injecting the agent according to steps c) and d).
    A final control is preferably carried out in the following spring. Only then, if no new shoots are detected, the treated area is released for new use with new plants.
    A chance of success of the inventive method that at a first final check in the first following spring no new shoots grow, is 95%.
    According to the invention and according to claim 10, an active agent for the removal of plants, such as invasive neophytes, disclosed. It contains triclopyr, a poorly water-soluble pre-emergence herbicide and water.
    An embodiment of the active agent according to the invention contains triclopyr, napropamide and water.Another embodiment of the active agent according to the invention contains triclopyr, oxyfluorfen and water.Further embodiments of the active agent according to the invention contain triclopyr, a sparingly water-soluble pre-emergence herbicide and water, the pre-emergence herbicide being an active ingredient from the group dimethachlor, clomazone alachlor, metolachlor, aclonifen and linuron. This active agent is also used in the process according to the invention.
    One embodiment of the active agent contains 0.5-10 grams of triclopyr and at least 1.7 grams of napropamide or oxyfluorfen each mixed in 1 liter of water.
    A particular embodiment of the active ingredient contains in each case 1 liter of water mixed 6.7 grams of triclopyr and 3.5 grams of napropamide or oxyfluorfen. This mixture is particularly suitable for the killing of bamboo, and is used in the inventive method for their elimination.
    A further embodiment of the active ingredient contains in each case 1 liter of water mixed 0.1-2 grams of triclopyr and at least 1.7 grams of napropamide or oxyfluorfen.
    Another particular embodiment of the active agent contains 1.4 grams of triclopyr and 3.5 grams of napropamide or oxyfluorfen each mixed in 1 liter of water. This mixture is particularly suitable for the killing of any Japanknöterich and is used in the inventive method for their elimination.
