The invention relates to a sprayer of the type comprising a turbine that generates an air current, a nozzle that channels the air current and an outlet of this current to the outside, carrying with it the product dosed by a series of nozzles arranged in the area of influence of the air current, the sprayer being special in that both the air outlet opening and the turbine can be configured and act in a coordinated manner to obtain the desired air flow for each type of crop and spray application, where the optimum air flow for each spray application and the configuration of the turbine and opening are determined by the actual sprayer by means of a processor and auxiliary means.

A spray bar injector including a spray bar defining a longitudinal axis and including a fluid inlet and a plurality of spray outlet orifices spaced apart longitudinally in a direction along the longitudinal axis. A check or spray valve is operatively connected to each spray outlet orifice. A master valve is in fluid communication with the fluid inlet, operatively connected to divert flow from the fluid inlet into a first passage and block flow into a second passage in a first position to open the check valves and issue a spray from the spray outlet orifices, and to divert flow from the fluid inlet into the second passage and block flow into the first passage in a second position to close the check valves and block issue of spray from the spray outlet orifices.

A system for applying CO.sub.2 gas to improve Cannabis production. A multi-stage system is disclosed including upstream, midstream, and downstream stages or subsystems. The upstream subsystem receives and stores gas, particularly CO2 gas. The midstream subsystem is communicatively connected to the upstream subsystem and to the downstream subsystem. It monitors the environment of the downstream subsystem, determines when and how to apply gas to plants growing in the downstream system, acquires gas stored in the upstream subsystem, and distributes it to the downstream system. It also has various monitoring, command and control, management, and reporting features. The downstream subsystem includes one or more plant growth areas or plots, gas distribution means, such as gas conduits, tubes or lines from the midstream subsystem, and the high efficiency, adjustable gas applicator, and various sensing and monitoring devices communicatively connected to the midstream subsystem.

Various embodiments of an apparatus, methods, systems and computer program products described herein are directed to an agricultural observation and treatment system and method of operation. The agricultural treatment system may determine a first real-world geo-spatial location of the treatment system. The system can receive captured images depicting real-world agricultural objects of a geographic scene. The system can associate captured images with the determined geo-spatial location of the treatment system. The treatment system can identify, from a group of mapped and indexed images, images having a second real-word geo-spatial location that is proximate with the first real-world geo-spatial location. The treatment system can compare at least a portion of the identified images with at least a portion of the captured images. The treatment system can determine a target object and emit a fluid projectile at the target object using a treatment device.

An air assist spray assembly for an aerial vehicle as shown and described. The air assist spray assembly may include a boom structure having a plurality of spray nozzles configured to dispense fine and course spray droplet sizes. The spray nozzle may be an electrostatic type of nozzle. The boom structure may include an air curtain system that includes an elongated air passageway with a plurality of air nozzles. The air curtain system may include a front air curtain and/or a rear air curtain to assist with directing the spray of electrostatically charged fine and coarse droplets from the spray nozzles towards vegetation.

Various embodiments relate generally to computer vision and automation to autonomously identify and deliver for application a treatment to an object among other objects, data science and data analysis, including machine learning, deep learning, and other disciplines of computer-based artificial intelligence to facilitate identification and treatment of objects, and robotics and mobility technologies to navigate a delivery system, more specifically, to an agricultural delivery system configured to identify and apply, for example, an agricultural treatment to an identified agricultural object. In some examples, a method may include calculating an amount of light originating from a light source sensed at a location in which an agricultural object is interposed between the light source and an image capture device, causing emission of an obscurant, and directing the obscurant to a region interposed between the light source and the agricultural object.

An apparatus for dispensing a treatment liquid to a respective agricultural crop, including means for diffusing the treatment liquid, which comprise means for emitting a flow of air for diffusion of the treatment liquid, in particular fan-style diffusion, and means for dispensing the treatment liquid inside the flow of air for diffusing the treatment liquid, connected with means, in particular a respective tank for containing the treatment liquid; the dispensing means including a dispensing body having an inner chamber for conveying the liquid, respective inlet opening means of the treatment liquid, and nozzle means for escape of the liquid in the flow of air for diffusion of the treatment liquid, in communication with or opening into the inner conveying chamber; the inlet into the conveying chamber being defined by a plurality of openings leading into the inner chamber for conveying the liquid.

Disclosed is a compact spraying module for spraying a liquid in the form of droplets for treating a target. The module includes a spraying unit including a nozzle containing at least one spraying member and a fan that is capable of generating a carrying air flow in the nozzle and of carrying the droplets originating from the member to the target. The module includes its own liquid supply system that and includes an electric pump, an electronic control and monitoring unit, a holder that keeps the pump near the spraying unit, an individual communication interface, and a power supply interface. Also disclosed is a system for spraying and controlling a plurality of such modules and to a method for controlling modules of such a system.
