Title: Method for controlling undesired plants in cultivated and uncultivated land
Inventor: KASTEN HEIDRUN DR
IPC: B24C11/00
Filed: 1993-04-30
Granted: 1994-11-17
Abstract: There is described a method for controlling undesired plants in cultivated and uncultivated land by injuring the above-ground parts of plants. In this method, a finely divided blasting agent is applied using a sand-blasting machine to the above-ground parts of the undesired plants in such a way that these die off as a result of sufficient surface damage. There is further described a finely divided blasting agent for carrying out this method, characterised in that its small solid particles have a particle size of 100 to 3000 mu m and are sharp-edged, fissured on the surface and/or porous, and their inner or outer surfaces are coated with a phytotoxic agent. The invention can be employed particularly advantageously in controlling the growth on railway tracks. To do this, customary spraying trains, which are equipped with a sand-blasting machine, with a high operating speed of about 40 km/h can be employed. Additionally, phytotoxic agents can be used which do not show any independent phytotoxic herbicidal activity.

Each semiframe is made of two parts coupled by longitudinal hinge for rolling of extreme axles with regard to middle one to both sides. Wheels are made hollow, and some parts of vehicle equipment are mounted in wheel spaces on wheel axles. Proposed method of changing direction of motion resides in that wheels of middle axle are first to be taken off ground and speed of rotation of wheels at one side is changed. As this takes place, extreme axles are brought closer due to bending articulated frame in lateral hinge, and direction of wheels rotation at above-mentioned side is changed for opposite one.
