A method of using a system to apply liquid over a selected area includes providing a source of liquid, a first tube for transporting liquid from the source through the system, a connector, a check valve and a spray device. The connector includes a projection extending into the first tube. The projection has an inlet in fluid communication with the first tube. The connector further includes an outlet and a passageway in fluid communication with the inlet of the projection and the outlet of the connector. The check valve has an inlet in fluid communication with the outlet of the connector and an outlet. The check valve is operable to permit the passage of liquid from the inlet to the outlet upon pressurization of the liquid above a threshold pressurization level. The method includes the steps of introducing an amount of liquid to be applied to the selected area from the source of liquid to the first tube at a pressure below the threshold pressurization level of the check valve and providing pressurized air through the first tube to pressurize the liquid in the first tube above the threshold pressurization level of the check valve, thereby transporting liquid from the first tube, through the connector and the check valve and through the spray device in response to pressurization of the liquid. The liquid may be ozonated water.

The invention relates to a sprayer of the type comprising a turbine generating an air flow that is conveyed through a main duct to a distributor from where the air flow is conveyed through ports to a plurality of secondary ducts which direct the air flow to the exterior, bringing same into contact with the product mixture metered by nozzles located in the area through which the outgoing air stream flows, where the invention is characterised in that the air flow from the secondary ducts can be regulated by means of opening and closure elements that operate in a coordinated manner with at least one overflow channel, such as to help maintain a constant pressure inside the air ducts, preventing air from flowing back to the turbine, which could alter the operating conditions selected for the equipment.

A first leg extends upward from the left frame and a second leg extends upward from the right frame to connect the legs to the beam. One or more satellite navigation receivers are associated with beam to determine a position and an attitude of the beam. One or more row units are suspended from the beam, such that the position of nozzle or nozzles on each row unit can be adjusted simultaneously and dynamically in multiple dimensions to maintain a target spacing between the nozzle and ground and the nozzle and a plant or row of plants.

A front-boom sprayer is provided that includes a boom center section and lift arm arrangement that provides a field of view below the boom when the boom is in a raised state that is substantially free of view obstructions from torque tube or other crosswise-extending components. The lift arm arrangement may provide different link tube geometries so that the respective left and right pairs of upper and lower lift arms align with each other in the line of sight of the in-cab operator.

The present invention is to provide an application and a method for controlling a moving vehicle that are capable to efficiently spray a chemical. The application for controlling a moving vehicle executed on an information terminal 100 mounted on the moving vehicle 10 acquires an image taken by the information terminal 100 in flight, analyzes the acquired image, detects a pest attached to a crop based on the result of the image analysis, acquires location information of the crop to which the detected pest is attached, and controls the moving vehicle 10 to spray a disinfestant based on the acquired location information.

A software process for controlling a configurable UAV that includes a plurality of databases of crop plants, herbicides, insecticides and weeds. An area is defined to be treated. Thereafter, a scout UAV with an on-board camera is flown over the pre-defined area. Images detected by the camera are compared with the crop, pest and weed databases to respectively identify the crop plants, insects, and weeds. The insects and weeds are then subjected to a spot blast of pesticide/herbicide to kill them. Thus, the process results in a more efficient application of treatment chemicals which leads to less adverse environmental impacts associated with the use of pesticides and herbicides.

A method of operating a fluid sprayer includes dispersing a first fluid selected from a group consisting of larvicide, adulticide, and a barrier repellant from the fluid sprayer with a first nozzle assembly at a first volumetric flow rate, replacing the first nozzle assembly with a second nozzle assembly, and dispersing a second fluid selected from the group from the fluid sprayer with the second nozzle assembly at a second volumetric flow rate different than the first volumetric flow rate.

An arrangement introduced into a motorized nebulizer equipped with a pneumatic nozzle for generating cold drops, which allows for the high efficiency of the application through the formation of a droplet spectrum within the range of sizes recommended by the World Health Organization (WHO) for the control of insects, in particular, mosquito vectors of human diseases, in flight, which is a spectrum with a median volumetric diameter (MVD) of less than 30 microns (m).
