The invention provides a system for equalizing airflow in lines delivering product-conveying air to boom sections of an agricultural machine by controlling valves, such as electronically, in each air distribution line to induce additional pressure drops in lines which would cause imbalance in the system. Such valves can include, but are not limited to: ball valves, butterfly valves, gate valves, globe valves, diaphragm valves, pinch valves and/or plug valves. With the proposed system, the lines of least pressure drop can be induced with additional pressure drop by particular valves in order to bring the lines back to a balanced state.

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 for dispensing multiple low rate agricultural products, includes a syringe-based 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.

A computing system is providing for managing a fleet of spraying vehicles by selecting one or more field zones to be sprayed by a fleet of spraying vehicles. The system reviews spraying requirements including material and quantity to be sprayed and reviews spraying vehicle parameters for each spraying vehicle in of the fleet. The system then calculates a travel plan for each spraying vehicle such that the selected field zones can be sprayed accordingly without spraying areas outside the selected field zones. Once in operation, the system verifies travel plan execution of each spraying vehicle and adjusts one or more travel plans in case of vehicle malfunctions, unexpected weather conditions, and unexpected field obstacles.

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 system uses a pump in combination with a fluid regulator to obtain and disperse fluid from the fluid tanks. The fluid regulator includes a fluid input port, a fluid output port and a fluid control valve. A first tube fluidly coupled from the fluid pump to the fluid input port. The system includes a moveable treatment head having one or more spraying tips, including a first spraying tip. A second tube is fluidly coupled from the fluid output port to the moveable treatment head. A system includes a controller configured to provide to the fluid regulator to open and close the fluid control valve to release an amount of the first fluid.

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.

Provided are a mosquito control aerosol which can produce a good control effect on mosquitoes over a long period of time while reducing influence on humans and pets, and a mosquito control method using the mosquito control aerosol. The mosquito control aerosol includes: a pressure-resistant container equipped with a metering spray valve, that contains a liquid aerosol-forming material including an insect pest control component and an organic solvent, and a propellant; and a spray button having a spray outlet connected to the metering spray valve. The volume of the liquid aerosol-forming material sprayed when the spray button is pressed down once is adjusted to 0.1 to 0.4 mL, and the spray force thereof as measured at a distance of 20 cm from the spray outlet at 25 C. is adjusted to 0.3 to 10.0 g.Math.f.

An agricultural plant protection machine and a diaphragm pump thereof are provided. The diaphragm pump includes a pump body including a containing cavity; a pump cover on the pump body; a diaphragm in the containing cavity, which and the pump cover surround to form a cavity; and a driving mechanism in the containing cavity. The driving mechanism includes a push rod, a coil assembly and an elastic reset member. The push rod is connected to the diaphragm and the elastic reset member. When the coil assembly is powered on and powered off alternately, the push rod makes a reciprocating linear motion to drive the diaphragm to reciprocate relative to the pump cover so as to reduce or enlarge the cavity.
