Definitions

  • This invention relates to a method for the control of fallopia japonica, a pernicious weed best known as Japanese Knotweed.
  • the method may also be used for the control of other species such as Giant Knotweed, and Knotweed hybrids.
  • Giant Knotweed and Knotweed hybrids.
  • the terms "Japanese Knotweed” and “Knotweed” as used herein should therefore be construed to include all such variants.
  • Japanese Knotweed typically spreads by propagation from rhizomes of existing plants via, for example, waterways, fly-tipping and soil movement.
  • the plant can also propagate from fragments of live stalks or shoots, and this has led to Knotweed spreading as a result of strimming, with the debris again being dispersed via waterways or fly-tipping.
  • New plants can grow from as little as 0.7g of live material. Its colonisation of areas has meant that native flora and fauna is displaced and extensive damage to indigenous species results.
  • Existing methods of controlling Japanese Knotweed include herbicidal application, and so-called "dig-and-dump" methods.
  • Conventional herbicidal application methods have met with limited success, because of the difficulty in delivering the herbicide to the plant's extensive underground rhizome system. The problem occurs because the herbicide is typically delivered to the plant's leaves and stalks, and must then be translocated down the stem of the plant to reach the rhizome system.
  • Dig-and-dump methods are costly, both financially and environmentally. Such costs include the diesel fuel used for transportation of the spoil and the - -
  • the present invention seeks to provide a more effective, economic and environmentally benign method for the control of Japanese Knotweed, by utilising the plant's own natural regeneration tendency to assist with the translocation of herbicide. Using the method of the present invention, it is believed that complete eradication of Japanese Knotweed from a site can be guaranteed, whilst utilising lower levels of herbicide compared to conventional methods.
  • the present invention also seeks to provide a flexible method to accommodate variations in the growth phase and local environment of target plants.
  • a method for the control of Japanese Knotweed comprising at least the steps of:
  • Stimulating the growth of the target plant is crucial to ensuring that the leaves and stalks of the plant are not completely killed before translocation of the herbicide through the rhizome system has been effected.
  • the growth stimulation step may occur either before or after the herbicidal application step, depending on the growth phase and local environment of the target plant.
  • composition of the herbicidal formulation selected will also depend upon these conditions.
  • the method of the present invention therefore preferably further comprises the preliminary steps of: - identifying said target plant, and characterising the growth phase and local environmental thereof; and
  • the herbicidal formulation utilised in the method of the present invention is preferably an aqueous composition comprising an active component selected from 4-amino-3,5,6-trichloropicolinic acid (picloram), N-(phosphonomethyl)- glycine (glyphosate), (3,5,6-trichloro-2-pyridyloxy)-acetic acid (triclopyr), and derivatives thereof, and a sticking agent selected from polyvinyl alcohols, synthetic latexes, poly-1 - ⁇ -menthene, and derivatives thereof.
  • an active component selected from 4-amino-3,5,6-trichloropicolinic acid (picloram), N-(phosphonomethyl)- glycine (glyphosate), (3,5,6-trichloro-2-pyridyloxy)-acetic acid (triclopyr), and derivatives thereof
  • a sticking agent selected from polyvinyl alcohols, synthetic latexes, poly-1 - ⁇ -menthene, and derivatives thereof.
  • the sticking agent is selected from poly-1 - ⁇ -menthene and derivatives thereof, as sold under the trade name NU FILM P, and is present in the aqueous composition in a concentration in the range of from 0.22% to 0.28%, most preferably 0.24% to 0.25%, by volume of the total composition.
  • the herbicidally active component is preferably selected from 4-amino-3,5,6-trichloropicolinic acid (picloram) and derivatives thereof, as sold under the trade name TORDON.
  • Picloram is preferably present in the aqueous composition in a concentration in the range of from 1.98% to 2.48%, most preferably 2.20% to 2.25% by volume of the total composition.
  • the herbicidally active component is preferably selected from N-(phosphonomethyl)-glycine (glyphosate) and derivatives thereof, as sold under the trade name ROUNDUP or ROUNDUP PRO-BIACTIVE.
  • Glyphosate is preferably present in the aqueous composition in a concentration in the range of from 2.62% to 3.30%, most preferably 2.91% to 3.00%, by volume of the total composition.
  • the herbicidally active component is preferably selected from (3,5,6- trichloro-2-pyridyloxy)-acetic acid (triclopyr) and derivatives thereof, as sold under the trade name TIMBREL.
  • Triclopyr is preferably present in the aqueous composition in a concentration in the range of from 1.55% to 1.96%, most preferably 1.72% to 1.75%, by volume of the total composition.
  • the step of stimulating the growth of said target plant preferably comprises chipping or cracking the rhizomes of the target plant. Most preferably, a barbed fork is utilised for said chipping or cracking.
  • the step of applying herbicidal formulation to the target plant preferably comprises spraying said herbicidal formulation from spraying apparatus having:

  • herbicidal formulation for use in a method of controlling Japanese Knotweed, as hereinbefore described.
  • Figure 1 is a flow chart representing a method for the control of Japanese Knotweed according to the present invention.
  • a trained operative starts with the preliminary step (1 ) of identifying a target plant and positively determining whether said plant is
  • the operative proceeds to characterise the growth phase (2) of said target plant as either growing (3) or dormant (4). If the growth phase is characterised as growing (3), the operative then proceeds to select the Fast Track Method (5), which will be discussed in more detail below. Alternatively, if the growth phase is characterised as dormant (4), the operative then proceeds to a step (6) of characterise the urgency for removal as either non-urgent (7) or urgent (8).
  • step (6) If it is determined in step (6) that there is no urgency (7) for removal of the Knotweed plant, the Fast Track Method (5) is again selected. Alternatively, if it is determined that the plant should be urgently removed (8), then the Rhizome Removal Method (9) is selected. - -
  • the Rhizome Removal Method (9) involves a first step (10) of preparing the site by removing all waste material therefrom, so as to leave bare earth. The site is then mechanically excavated (11 ) so as to remove all Knotweed rhizomes therefrom. The excavated rhizomes (12) are then subjected to the Fast Track Method (5), as will now be described in detail.
  • the Fast Track Method (5) involves a preliminary step (13) of characterising the site conditions as either near trees (14), near watercourse (15) or clear (16), and selecting a herbicidal formulation comprising an active component appropriate to those conditions: if the site is near trees (14), triclopyr is selected as the active component (17); if the site is near a watercourse (15), glyphosate is selected (18); and if the site is clear (16), picloram is selected (19).
  • the remainder of the process will be determined by the previously made characterisation of the growth phase (2) as either growing (3) or dormant (4).
  • the growth phase was characterised (2) as growing (3)
  • the following sequence of successive steps is carried out: firstly, the selected herbicidal formulation is applied to the target plant (20); then the site is prepared as described above (10); and then the growth of the target plant is stimulated (21 ) so as to promote translocation of the selected herbicidal formulation throughout the target plant's rhizome system.
  • the growth stimulation step (21) is achieved by chipping or cracking the plant's rhizomes with a barbed fork.
  • the sequence of steps differs in that the site preparation (10) and growth stimulation (21) steps precede the application of the selected herbicidal formulation (22) - -
  • a trained operative examines the target plant (23) at regular intervals and determines whether there is any re-growth (24) or no re- growth (25). If re-growth (24) has occurred, the selected herbicidal formulation is re-applied once the new growth reaches a height of 1 metre, as described above (22). Step (23), and if necessary step (22), is then repeated until a negative assessment of the re-growth (25) is obtained. Finally all waste material, including any excavated material from step (11 ) if the preliminary Rhizome Removal Method (9) was carried out, is disposed of (26) as controlled waste.

Abstract

L'invention concerne un procédé de lutte contre la renouée du japon, ou Fallopia japonica, qui consiste d'abord à identifier la renouée du japon, la renouée de Sakhaline, ou la plante hybride (1) cible et à caractériser sa phase de croissance (2) comme étant 'active' ou 'dormante'. Puis, l'environnement de la plante cible est évalué (13) et caractérisé comme étant 'proche d'arbres', 'proche d'un cours d'eau', ou 'dégagé'. Une formulation herbicide appropriée à la phase de croissance ainsi qu'à l'environnement caractérisés est alors sélectionnée (17, 18, 19). Par ailleurs, le traitement de la plante cible consiste à appliquer la formulation herbicide à la plante (20, 22) et à stimuler la croissance de la plante (21) de manière à favoriser la translocation de la formulation herbicide dans le système rhizome de la plante cible.
