摘要:
The present invention relates to an apparatus for eradication of invasive species of hogweed: Heracleum sosnovskyi, Giant Hogweed (H. mantegazzianum), and/or H. persicum and method of their eradication using the apparatus. The apparatus according to the invention comprises of a longitudinal handle (1), to which a spike (3) is fastened stiffly, and around the spike (3) there is a coil spring (2) fixed to the handle (1), to which there is attached a hole saw cutter (4) at a free end; inside the coil spring (2) there is fixed a compressible well-absorbing material (5), the said coil spring (2) with the hole saw cutter (4) is shorter than the spike (3). Method for hogweed eradication according to this invention consists in that after locating hogweed, since spring there are sought namely two-year and older plants of 0.5÷1 m height and then such plant(s) is(are) to be pricked vertically with an apparatus according to the invention monitoring that the spike enters 10÷20 cm below soil level into the plant root through a root neck, while during pricking a shoot (stem and petioles) is cut and destroyed with hole saw cutter, and due to spring compression on absorptive material there is applied herbicide, which has been previously added to the material; the herbicide flow down both onto shoot and into root through grooves in the spike. The procedure is to be repeated for 4-5 years on newly come-up plants up to destroying all individual plants in one place, paying attention that a single plant does not seed.

The present invention relates to a tool for eradication of invasive hogweed species consisting of longitudinal handle and characterises in that at the end of handle corpus (1) there is placed cylindrical ending (2), which upper part is stiffly joined with the handle corpus (1), while the bottom part (3) is truncated at an acute angle and it is sharpened producing a blade (4), additionally in a half of the ending (2) length there is an oval hole (5) located over the blade (4), whereby inside the ending (2) there is a cylinder (6), which bottom ending is truncated at the same angle as the blade (4) and the bottom end of the cylinder (6) is over the hole (5). Method of eradication of invasive hogweed species consists in that using the tool according to the invention, a hogweed stem is punctured just over soil surface, but not cutting away from underground part of the plant, whereby the most suitable plants are those with flower buds and with unripe (green) seeds; the procedure is to be repeated up 5 seasons at same site against all seed producing specimens in order to achieve complete the hogweed eradication at the site
