    Short designation: Pesticide against Japanese Thousand Knot
    DESCRIPTION The invention relates to a plant control agent of the genus Fallopia, in particular the Fallopia japonica (Japanese knotweed); see nttps: //nl.wikipedia.org/wiki/Japanese knotweed.
    The persistent Japanese knotweed has been able to proliferate in the Netherlands in recent years. This invasive exotic plant causes a lot of nuisance nowadays and is difficult to combat. Its roots are strong and can become meter-long, causing damage to foundations, underground pipes or dikes.
    The present invention aims to provide a 100% natural control agent that is biodegradable. The agent developed according to the invention on the basis of natural ingredients is preferably injected into the stems of the plant, as a result of which the plant will die and rot in the foreseeable future.
    The proposed pesticide, in particular against Japanese knotweed, comprises the following ingredients: - Acetic acid (see e.g. .wikipedia.org / wiki / Acetic acid)
    - Citric acid (see for example nl.wikipedia.org/wiki/Citric acid) and / or Ascorbic acid (see for example https: //nl.wikipedia.org/wiki/Ascorbic acid).
    Preferably, the pesticide according to the invention comprises a substantial percentage of garlic extract or garlic concentrate and / or (natural or nature identical) Allicin (see, for example, nl.wikipedia.org/wiki/Allicin), optionally obtained from a source other than garlic. Preferably, the proposed pesticide comprises a very small percentage of one or more gum species (see, for example, nl.wikipedia.org/wiki/Gum (substance)). It has been found that the following ingredients, both individually and in combination with each other, have been found to be very suitable for use as gum in the pesticide according to the invention: Locust bean gum / gum (see, for example, nl.wikipedia.org/wiki / Locust bean gum), - Guar gum / gum (see, for example, nl.wikipedia.org/wiki/Guargom), - Xanthan gum (see, for example, nl.wikipedia.org/wiki/Xanthan gum).
    The pesticide according to the invention preferably comprises the following composition: e Acetic acid approx. 10-30 wt% and e Citric acid and / or Ascorbic acid, ie either Citric acid or Ascorbic acid, or a combination / mixture of (partly) Citric acid and (partly) Ascorbic acid) about 30-50% by weight and Garlic extract / conc. and / or Allicine about 30-50% by weight and one or more gums such as Locust bean gum / gum and / or Guar gum / gum and / or Xanthan gum and / or optionally one or more other gums in total 0 - 2% by weight, the whole diluted with water if desired.
    Successful tests with the control of Japanese knotweed have meanwhile been carried out with a pesticide according to the invention having the following composition: e Acetic acid approx. 20% by weight and e Citric acid and / or Ascorbic acid approx. 40% by weight and e Garlic extr./conc . (500,000 ppm) approx. 39.5 wt% and e locust bean gum / gum approx. 0.1 wt% and e guar gum / gum approx. 0.2 wt% and e Xanthan gum approx. 0.2 wt%, the whole if desired diluted with water.
    The pesticide according to the invention can be produced by combining said ingredients and mixing them for at least 2 minutes, preferably at least 4 minutes.
    Thus, the present invention provides a natural Japanese knotweed control agent that is readily biodegradable. The proposed agent is preferably injected into the stems of the plant, whereby the plant dies and digests completely within a foreseeable period of time.
