A system for dispensing multiple low rate agricultural products, includes an agricultural product metering system, a number of agricultural product tubes, and an agricultural product metering system. The agricultural product metering system is operably connected to sources of low rate agricultural products. The agricultural product tubes are operatively connected to the agricultural product metering system. The agricultural product metering system is configured to dispense liquid low rate agricultural products at a low rate defined as below 3.7 fluid ounces per 1000 row feet.

Various embodiments of apparatuses, methods, systems, and computer program products described herein are directed to a treatment system. An example apparatus includes a treatment apparatus having a first fluid source, one or more channels for delivering a first fluid of the first fluid source, and a treatment unit, the treatment unit having one or more fluid regulators, including a first fluid regulator configured to regulate a flow of the first fluid received by the treatment unit, a movable treatment head unit having one or more spraying tips, a first channel fluidly coupling the one or more spraying tips with the first fluid regulator, wherein the first fluid regulator controls a volume of fluid emitted from the one or more spraying tips, an one or more controllers disposed in the treatment unit configured to control the one or more fluid regulators.

A sprayer system includes a diluent tank, a mounting bracket mounted to the diluent tank and a concentrate tank mounted to the mounting bracket and diluent tank. A mixing manifold is mounted to the mounting bracket and has a first inlet fitting to receive a fixed amount of diluent and a second inlet to receive a liquid concentrate. The diluent and concentrate are then combined to form a mixed solution. The mixing manifold includes an outlet. A positive displacement pump is mounted to the mounting bracket and has a suction port fluidly coupled to the mixed solution outlet. A pressure port may fluidly couple with a spray device. The second tank may be separable from the first tank and mounting bracket without requiring removal of the mixing manifold or positive displacement pump.

A fluid dispersion system and method used for spraying large areas with near-monodispersed, aerosolized fluid droplets. More specifically, the system creates and distributes a cloud of near-monodispersed droplets of fluid by pumping pressurized air and fluid through fluid dispersion machinery and into, and out of, a fluid dispersion nozzle. The fluid dispersion machinery is a combustion engine-driven air compressor system that includes an engine, radiator, fuel tank, fluid tank, fluid piping system, fluid pump, air compressor, air compression intake, one or more fluid dispersal nozzles, air ducting, clutch, and control system. The method of fluid dispersion is implemented at night during a nighttime air inversion when there is a temperature difference between the temperature of air at the top of an object and the temperature of air near the ground surface.

A fluid dispersion nozzle and system for spraying large areas with near-monodispersed, aerosolized fluid droplets. More specifically, the fluid dispersion nozzle receives pressurized and fluid from fluid dispersion machinery, aerosolizes the fluid into near-monodispersed droplets, and distributes the aerosolized, near-monodispersed droplets evenly over long distances. The nozzle is an adjustable, dual-contour, supersonic nozzle that includes a main adjustable contour, an auxiliary contour, an axial fluid injector, a resonator, and a plunger.

Methods and systems for generating a plasma-activated liquid or gas, and applying the plasma-activated liquid for agricultural use. A system embodiment includes a hand-held device that can be pointed and directed at different target areas of a plant. A method embodiment includes generating a plasma discharge in a gas environment or a liquid environment, and applying the gas/liquid to a plant.

A system is provided for applying a chemical agent within a pipe. The system includes a skid assembly, moveable longitudinally within the pipe and a delivery nozzle carried by the skid assembly and coupleable to an external chemical agent supply. A dispensing tip is carried by the delivery nozzle, the dispensing tip being configured to deliver a controlled stream of chemical agent within the pipe toward an internal surface of the pipe. The dispensing tip is held above a surface of fluid carried by the pipe while at least a portion of the skid assembly is positioned below the fluid surface. The dispensing tip delivers the controlled stream of chemical agent upwardly away from the fluid surface.

The present invention is directed to a nozzle holder, having a body, a dispensing chamber, a plurality of valves in the dispensing chamber, movable between an open and closed position, a rotationally movable plate in contact with a first end contact surface of each valve to control the movement of said valve between its two positions; wherein the peripheral edge of the plate has high and low edge portions, in the opening position of a valve, the first end contact surface is in contact with a first plate edge portion, and in the closing position, the first end contact surface of the valve is in contact with a second plate edge, the second edge being different from the first edge.

A sprayer system includes a diluent tank, a mounting bracket mounted to the diluent tank and a concentrate tank mounted to the mounting bracket and diluent tank. A mixing manifold is mounted to the mounting bracket and has a first inlet fitting to receive a fixed amount of diluent and a second inlet to receive a liquid concentrate. The diluent and concentrate are then combined to form a mixed solution. The mixing manifold includes an outlet. A positive displacement pump is mounted to the mounting bracket and has a suction port fluidly coupled to the mixed solution outlet. A pressure port may fluidly couple with a spray device. The second tank may be separable from the first tank and mounting bracket without requiring removal of the mixing manifold or positive displacement pump.

A system for controlling fluid flow includes a fluid inlet operable to receive a fluid flow, a fluid outlet operable to output the fluid flow, a diaphragm seat, a diaphragm operable to restrict the fluid flow between the fluid inlet and the fluid outlet by moving between an open position where the first diaphragm does not contact the diaphragm seat to a closed position where the diaphragm contacts the diaphragm seat, a spring operable to move the first diaphragm between the open position and the closed position, and a pressurized air inlet operable to receive pressurized air to move the first diaphragm between the open position and the closed position.
