A device for killing or weakening plants and other organisms, has a conveying device for moving the device, a high voltage source and an applicator which is electrically connected to a high voltage source and which has a sensor-guided height-adjusting device. The invention also relates to a method for using the device.

The present invention relates to a railway weed control vehicle. It is described to activate (110) at least one weed control unit to control weeds along and around a railway track. The railway track comprises rails and sleepers. The at least one electrode based weed control unit is mounted at at least one first position of the vehicle. Sensor data is acquired (120) by at least one sensor. The sensor data relates to at least one location along and around the railway track. The at least one sensor is mounted at at least one second position of the vehicle. With respect to a forward movement direction of the vehicle the at least one second position is in front of the at least one first position. The sensor data is provided (130) to a processing unit. The sensor data is analysed (140) by the processing unit to determine locations of rail infrastructure components in addition to the rails and sleepers. The processing unit modifies (150) activation of one or more electrode based weed control units of the at least one electrode based weed control unit comprising utilisation of at least one location of the determined locations of the rail infrastructure components.

An improvement to a roadside sprayer fixates spray nozzles on a registration plate. The registration plate may include integral tabs depending on the application. Inclination of the tabs is adjustable to place streams and droplets in a desired swath coverage. With the nozzles rigidly mounted onto the plate, the entire plate is nutated. The use of the registration plate in a spray unit creates a uniform nutation among the nozzles, thereby reducing variability in droplet placement, and providing a more predictable spray from the nozzles. In other embodiments, the spray unit is utilized in a spray system adaptable to service vehicles, and may be utilized in conjunction with a vegetation engagement device, such as a cutter to engage multiple zones of a roadway right-of-way. Additionally, an improved spray unit includes an electromagnetic field and an attractor to generate plate motion.

A functional sheet manufactured with staple fibers is provided. More particularly, a functional sheet is formed as a single layer or a composite layer by binding polyolefin staple fibers by needle punching, to enhance physical properties of the functional sheet so that the functional sheet may be used for various purposes, for example, for weed growth prevention, waterproofing, soundproofing, ground stabilization, civil engineering, construction and aging-friendly materials.
