Abstract
Ragwort isolation apparatus 10 comprising a cover plate 12, an anchor wall 14 and a ventilation aperture 16. The cover plate 12 is formed from a rigid, brightly coloured plastic which is impregnated with fragrance that is distasteful to animals. The lower most edge (14a, fig 3) of the anchor wall is chamfered, to form a cutting surface by which the anchor wall may be easily pushed into the ground by a user. The ragwort isolation apparatus is intended to be used in conjunction with herbicide spraying of a plant. The ragwort plant is sprayed with the selected herbicide and the apparatus is placed over the top of the plant, ensuring that no leaves protrude. The apparatus separates animals from the sprayed plant. The sheltered environment formed by the apparatus speeds up the action of the herbicide on the plant and encourages worm and insect action on the plant material. The cover plate can be flat, domed, conical or formed from mesh. The anchor wall may also take the form of a single spike, series of spikes or a screw thread.
Description
I
Ragwort isolation apparatus and removal system The invention relates to ragwort isolation apparatus and to a ragwort removal system.
Ragwort is a plant that is native to the United Kingdom and whilst it is considered to be beneficial to many species of fauna, it is extremely poisonous to any animal with a liver.
The presence of ragwort within pasture land is a particular problem when it is present on land occupied by horses and cows, and the ragwort plant must be removed from the land before it is safe to leave animals grazing on the land. There are many known methods of removing ragwort, including: digging or pulling the plant up from the ground by the roots, which can disturb dormant seeds, and lead to further re-growth of plants; pulling the plant up by the stem, either manually or mechanically; burning, which has dramatic immediate effects, but the plant will generally re-grow with increased vigour within as little as 3 weeks; cuffing/mowing to control the flowering seed heads of the plant, however the damage caused to the plant by these methods often causes the plant to change its growing habit from biennial to perennial, and these methods generally leave the cut and wilted plant parts on the ground which can easily be consumed by animals as they start to lose their bitter taste as they wilt; and poisoning with herbicide. The method of poisoning with herbicide is the most reliable, but using herbicide is not without its problems as it can take several weeks for the plant to wilt and die, and the herbicide makes the dead leaves more palatable to animals, whilst doing nothing to reduce the toxicity of the plant.
According to a first aspect of the invention there is provided ragwort isolation apparatus comprising: a cover member adapted to cover the leaves of a ragwort plant; and anchor means coupled to the cover member and adapted to engage with the ground around a ragwort plant.
The apparatus enables a ragwort plant that has been treated with herbicide to be covered and isolated from any animals in, for example, the field in which the plant is located. The cover member protects the leaves of the ragwort plant from rain, and thus prevents herbicide being washed off. The cover member additionally provides a green-house type effect on the ragwort plant, encouraging a build up of dampness and warmth around the plant which accelerates the action of the herbicide, and encourages worm and insect activity to disperse dead plant material. .The apparatus prevents access to the ragwort plant by any animals, and prevents animals from eating the plant.
The ragwort isolation apparatus preferably further comprises a ventilation aperture adapted to allow air to circulate around the device and the leaves of a ragwort plant isolated by the device.
The ventilation aperture allows air to circulate around the leaves, thereby facilitating the metabolism of the herbicide across the leaves.
The cover member may be flat, or may be generally domed or conical in shape. The cover member is preferably a solid cover member. A ventilation aperture is preferably provided in the cover member. The cover member may alternatively comprise a mesh cover member, the mesh apertures forming ventilation apertures.
The anchor means preferably comprises an anchor wall provided around and coupled to the outer edge of the cover member. The anchor wall may be permanently coupled to the cover member or may be hingedly or removably coupled to the outer edge of the cover member.
The anchor wall is preferably chamfered at its free end. This allows the anchor wall to be easily pushed into the ground.
The anchor wall may alternatively be provided with a screw thread on its external surface. The screw thread enables the apparatus to be screwed into the ground.
A ventilation aperture may be provided in the anchor wall. Alternatively, the anchor wall may comprise a spaced series of anchor wall elements.
The anchor means may alternatively comprise series of anchor pegs provided around the edge of the cover member.
The anchor means may alternatively comprise an anchor spike, which is most preferably generally centrally provided on the cover member. The anchor spike may comprise a hollow spike having one or more herbicide delivery apertures provided therein. The anchor spike thereby forms delivery means for delivering herbicide to the roots of a ragwort plant.
Preferably, at least the cover member is formed from a rigid plastic, which most preferably comprises an ultra-violet stable plastic.
The apparatus is thereby strong enough to withstand being stood on by a user or an animal, and its strength will not degrade during use due to UV exposure.
The plastic is preferably a brightly coloured plastic. The apparatus is thereby easily visible within the wider environment.
The plastic may be impregnated with a fragrance which is unpleasant to animals. Any animals discovering the apparatus will therefore be dissuaded from approaching too closely, or attempting to eat or chew the apparatus.
According to a second aspect of the invention there is provided a ragwort removal system comprising: ragwort isolation apparatus as claimed in any preceding claim; and a herbicide adapted to kill ragwort plants.
The herbicide is preferably a 2,4D esther.
Embodiments of the invention will now be described in detail, by way of example only, with reference to the accompanying drawings, in which: Figure 1 is a diagrammatic representation of Ragwort isolation apparatus according to a first embodiment of the invention; Figure 2 is a diagrammatic view from below of the apparatus is Figure 1; Figure 3 is a diagrammatic representation from the side of the apparatus of Figure 1; Figure 4 shows the apparatus of Figure 1 inserted into the ground around and covering a Ragwort plant, showing (a) the device positioned correctly and (b) the device positioned incorrectly, at an angle; Figure 5 illustrates how the apparatus of Figure 1 may be removed from the ground using a hoof pick; Figure 6 is a diagrammatic representation of a Ragwort isolation apparatus according to a second embodiment of the invention; Figure 7 is a diagrammatic side view of a Ragwort isolation apparatus according to a third embodiment of the invention; Figure 8 is a diagrammatic side view of a Ragwort isolation apparatus according to a fourth embodiment of the invention; Figure 9 is a diagrammatic representation of a Ragwort isolation apparatus according to a fifth embodiment of the invention; Figure 10 is a diagrammatic representation of a Ragwort isolation apparatus according to a sixth embodiment of the invention; Figure 11 is a diagrammatic representation of a Ragwort isolation apparatus according to a seventh embodiment of the invention; Figure 12 is a diagrammatic representation of a Ragwort isolation apparatus according to an eighth embodiment of the invention; and Figure 13 is a diagrammatic representation of a Ragwort isolation apparatus according to a ninth embodiment of the invention Referring to Figures 1 to 5, a first embodiment of the invention provides a Ragwort isolation apparatus 10 comprising a cover member 12, an anchor wall 14 and a ventilation aperture 16.
In this example, the cover member 12 comprises a flat plate of a rigid, brightly coloured plastic, which is a UV stable plastic (to prevent the material becoming brittle due to exposure to freezing temperatures and sunlight). The plastic is also impregnated with fragrance that is distasteful to animals.
The anchor wall 14 comprises a cylindrical wall and is fixed to the underside of the cover member 12; it extends downwardly from the cover member 12 and around the full circumference of the cover member 12. The anchor wall 14 is similarly fabricated from a rigid, brightly coloured UV stable plastic impregnated with fragrance. As shown in Figure 3, the lower most edge 14a of the anchor wall 14 is chamfered, to form a cutting surface by which the anchor wall may be easily pushed into the ground by a user. The ventilation aperture 16 is provided centrally in the cover member 12.
In this example, the cover plate 12 and the anchor wall 14 are formed as a single moulded element. The cover plate 12 has a diameter of approximately 170mm and a thickness of approximately 5mm. The apparatus 10 is therefore suitable to cover a Ragwort plant that is 7-l0cms across, which is considered to be the optimum size for treating a Ragwort plant by herbicidal spot spraying. The ventilation aperture 16 has a diameter of 7mm, to allow sufficient ventilation to the sprayed Ragwort plant to enable the correct functioning of the leaves to ensure that the herbicide is metabolised correctly, whilst ensuring that the herbicide is not washed off by any rain falling on the apparatus 10. The anchor wall 14 has a height of approximately 40mm, so that there is sufficient wall depth to be secured into the ground, without risk of the wall 14 cutting through the roots of the ragwort plant. The anchor waIl 14 has a thickness of approximately 4mm, in order to give the walls sufficient strength to be pushed into the ground and to withstand being stamped into the ground or trodden on by an animal.
The ragwort isolation apparatus 10 is intended to be used in conjunction with herbicide spraying of the plant as follows. Plants having a leaf diameter of no greater than 7 to 10 cm may be sprayed directly, while larger plants should first be trimmed to a small enough size to be covered by the isolation apparatus 10. The Ragwort plant is sprayed with the selected herbicide, such as a 2,4D Esther, and the Ragwort isolation apparatus is placed over the top of the plant, ensuring that no leaves protrude, and trodden down into the ground using body weight and a stamping action until the device is firmly located in the ground, as shown in Figure 4a. The bright colour of the device 10 allows a user to easily, visually identify the location of the device 10 within, for example, a field, and can also act as a visual deterrent to an animal (having colour vision) from standing on the apparatus 10. The unpleasant fragrance impregnated in the plastic acts to deter animals from approaching the apparatus and/or attempting to eat, lick or chew the apparatus 10.
The ragwort isolation apparatus 10 should typically be left in place over the ragwort plant for a period of about 3 weeks, to ensure that the plant is completely dead and substantially or fully rotted back into the ground. The apparatus 10 can be removed periodically to inspect the progress of the ragwort plant, either by manually prising the apparatus 10 out of the ground, or levered out using a screwdriver or hoof pick 18 placed under the outer edge 12a of the cover plate 12, as illustrated in Figure 5. The sheltered environment formed by the apparatus 10 around the ragwort plant encourages worms and insect action on the plant material, resulting in the plant material being quickly taken back into the soil. When the ragwort plant is completely dead, the isolation apparatus 10 can be finally removed, and any remaining plant material cleared away.
As will be appreciated, the ragwort isolation apparatus 10 can be reused many times.

The cover plate 12 is attached to the anchor wall 14 by a mechanical hinge 82, thereby allowing a user to lift the cover plate 12 away from the anchor wall 14 during use of the apparatus 80, to allow inspection of the plant within the apparatus 80 without needing to remove the isolation apparatus 80 from the ground.
A ragwort isolation apparatus 90 according to a ninth embodiment of the invention is shown in Figure 13. The apparatus 90 is substantially the same as the apparatus 10 of the first embodiment, with the following modifications. The same reference numbers are retained for corresponding features.
In this embodiment, the cover plate 12 does not have a ventilation aperture provided in it. The cover plate 12 is formed separately from the anchor waIl 14. Mechanical fixing clips 92 are provided on the cover plate 12 by which the cover plate 12 is secured to the anchor wall 14. The cover plate 12 may therefore be removed from the anchor wall 14 during use to allow for inspection of the plant within the apparatus 90.
Various modifications may be made to the described embodiments without departing from the scope of the invention. In particular, the apparatus may be of an alternative, non-circular, shape to that described. A different number and arrangement of ventilation apertures may be provided to those described.
The described embodiments provide the advantage that the ragwort isolation apparatus serves to separate an animal from a toxic plant, particularly whilst the plant is being treated with herbicide. The apparatus provides a sheltered environment around a herbicide treated plant which prevents the herbicide from being washed off due to rainy weather and forms a green-house type effect on a plant underneath the apparatus, causing a build up of warmth and dampness which accelerates the action of a herbicide on the plant.
