The invention relates to a spray unit comprising an axle (10), a disc (20), a liquid applicator (40) and a spray direction assembly (50). The disc is configured to spin about the axle centred on the centre of the disc. The liquid applicator is configured to apply liquid to a surface of the disc. The spray direction assembly partially surrounds the disc. The inner surface of the spray direction assembly is configured to modify the trajectory of all liquid that leaves the outer edge of the disc.

A chemical agent-spraying device is provided with a chemical agent tank and chemical agent-jetting parts that jet out a chemical agent supplied from the chemical agent tank. The chemical agent-jetting parts include a first chemical agent-jetting part that jets out the chemical agent onto the reverse surfaces of crop leaves as an area to which the chemical agent is to be jetted, and a second chemical agent-jetting part that jets out the chemical agent onto the obverse surfaces of crop leaves as an area to which the chemical agent is to be jetted.

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 notated. 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.

An apparatus and method of applying liquid product to a crop growing in a field. A plurality of drop assemblies are laterally spaced along the boom structure, each of the plurality of drop assemblies include a boom mounting bracket which supports a vertical support member and a spray assembly disposed at a lower end of the vertical support member, the boom mounting bracket having a first pivot axis oriented substantially perpendicular to the boom structure. The drop assemblies are movable from a working position to a transport position. In the transport position the vertical support member is pivoted about the first axis such that the vertical support member is oriented toward the boom structure. In the working position the vertical support is oriented substantially perpendicular to the boom structure.

A method of treating an area infested with bed bugs, includes applying to the infested area an amount of an isopropyl alcohol-denatured alcohol blend effective to kill the bed bugs. The alcohol blend composition is a bed bug control composition including, 25 vol. % to 33 vol. % denatured alcohol and 66 vol. % to 75 vol. % isopropyl alcohol.

Described herein are implements and application units for placement of fluid applications with respect to agricultural plants of agricultural fields. In one embodiment, an application unit includes a frame to be positioned in operation between two rows of plants and a plurality of flexible members coupled to the frame in operation such that the plurality of flexible members guide a lateral position of the frame to be approximately equidistant from the two rows of plants based upon whether at least one flexible member of the plurality of flexible members contacts one or more plants of the two rows of plants. The plurality of flexible members include a plurality of fluid outlets for spraying crop input in close proximity to the rows of plants.

An agricultural treatment system can include one or more motor assemblies, linkage assemblies coupled to the motor assemblies, and a treatment head assembly coupled to the linkage assemblies. Each motor assembly can rotate about a motor assembly rotational axis and each linkage assembly can move in a direction in response to motor assembly rotation about a motor assembly rotational axis. Portions of the treatment head assembly can rotate about one or more treatment head assembly rotational axes in response to linkage assembly movement. The treatment head assembly can include a treatment head, a fluid port that delivers a fluid into the treatment head, spraying tip(s) that spray the fluid onto an agricultural target object, and a fluid regulator that delivers the fluid from the fluid port to the spraying tip(s). The fluid regulator can be coupled to and can rotate with the treatment head, which can be movable.

The direct-injection spraying device, in particular for an agricultural vehicle, according to the invention includes a main tank, at least one spray boom, and a circuit connecting the tank to the boom. comprises: The circuit includes a main pump and a bypass for controlling the flow rate in the boom in accordance with the traveling speed of the vehicle. At least one active substance store is connected to the circuit by a metering pump. The device further includes a cyclone mixer capable of receiving, as input, the liquid from the main tank, and the pressurized liquids coming from the active substance store, and capable of eliminating the boom as output.

The present invention provides an improved mechanism for centering implements in agricultural fields by providing a laser guidance system with a laser attached to the implement. The laser may operate to emit a beam in order to produce a spot or beam onto the field which an equipment operator may visually target to improve steering of the implement. The laser may be centered on the implement, and the beam produced by the laser may be directed forward within a steering range of the implement and within a field of view of the equipment operator.

An autonomous spraying platform is provided. The autonomous spraying platform has a main frame platform supported by a first and a second wheel in tandem. Supported by the main frame platform and extended perpendicular thereto are extended booms having multiple movable and/or telescoping arms which touch the ground on each side by small wheels for balance and sensing of the ground. Liquids, foams or powders, which may carry pesticides, herbicides, insecticides, fungicides, fertilizers or other pro-growth ingredients, may be dispensed across the bottom edge of the extended booms. The main frame platform may be controlled locally by sensors utilizing GPS (or other positioning technology) or remotely by a computer or even alive operator. The device may allow for real-time precise delivery of pro-growth materials to plants.
