Provided is a discharge apparatus using an aerosol container, including a holding container for holding contents, a pressurizing unit configured to inject a filling material within the holding container by the aerosol container to pressurize the holding container, and a discharge unit configured to discharge the contents to the outside of the holding container. An unmanned aerial vehicle including the above-described discharge apparatus is also provided. A discharge method using an aerosol container, comprising: holding contents of a holding container; injecting a filling material within the holding container by the aerosol container to pressurize the holding container; and discharging the contents to the outside of the holding container is also provided.

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 for applying a chemical agent within a pipe includes a skid assembly, moveable longitudinally within the pipe. The skid assembly has a bottom positionable on a bottom, internal portion of the pipe. A delivery nozzle is carried by the skid assembly and is coupleable to a chemical agent supply. A dispensing tip delivers a controlled stream of chemical agent within the pipe toward an internal surface of the pipe. The tip is held at or 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 is limited from delivering the chemical agent downwardly toward the bottom of the skid assembly such that the dispensing tip delivers the controlled stream of chemical agent upwardly away from the bottom surface of the pipe and upwardly away from the fluid surface.

A system for dispensing low rate agricultural products, includes a syringe-based agricultural product metering system, at least one agricultural product tube, and an agricultural product metering system. The agricultural product metering system is operably connected to a source of low rate agricultural products. The agricultural product tube is 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 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.

A water lance provided with a diaphragm pump comprises a nozzle, a lance body and a water absorption ball. A diaphragm pump and a motor for driving the diaphragm pump are disposed in the lance body. The diaphragm pump drives water to be absorbed by the water absorption ball and to be sprayed by the nozzle, and comprises a rotating assembly, a swing component, a diaphragm assembly and a housing. The rotating assembly has an end connected to the motor and an end connected to the diaphragm assembly through the swing component. A pump chamber is formed by the diaphragm assembly and the housing. A split-type diaphragm pump is used as a liquid pump of a spraying facility, and all separated components are fixed through clamp springs and are assembled or disassembled step by step, so that parts can be replaced specifically, and later maintenance is facilitated.

The present invention is related to a plant biostimulant adjuvant and a method of treating a crop with a plant biostimulant adjuvant. The plant biostimulant adjuvant comprises a plant biostimulant comprising at least one of an amino acid or a peptide derived from a plant source. The plant biostimulant adjuvant also comprises an alkyl amine alkoxylate defined by the formula:

##STR00001##

wherein:
R.sup.1 is an alkyl of 6 to 22 carbons;
each R.sup.2 and R.sup.3 are each independently H or CH.sub.3.
n and m are each at least one and taken together n+m is 5 to 25;
and water.

The present invention is directed to a compact robotic device for spraying a biocide powder or liquid to a predetermined area for controlling the infestation by cockroaches and fleas. The compact robotic device comprises a robotic body that can autonomously travel to spray the powder or liquid. The compact robotic device comprises a cartridge containing the biocide powder, a spray head in fluid communication with the cartridge and configured to spray the powder or liquid over a surface and a pump coupled to the cartridge for affecting the flow of powder or liquid from the cartridge to the spray head.

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.
