A fluid injection device includes a housing and a valve stem. The housing includes an inlet arm having an inlet orifice for receiving a feeder fluid. An outlet arm has an outlet orifice to discharge a mixed fluid. A venturi tube is between the inlet and outlet arms. The inlet arm, veturi tube and outlet arm define a nonlinear fluid pathway where the venturi tube redefines a portion of the nonlinear fluid pathway as a constricted fluid pathway. A diverter port is used to divert a portion of the feeder fluid from the inlet arm into the container and an injection port is used to receive product from the container. A valve arm is collinearly aligned with the venturi tube and the valve stem is positioned within the valve arm and adjusts the volume of the constricted fluid pathway.

A further subject matter of the present invention is use of the device according to the invention in the area of agriculture, in particular for treating cultivated plants with plant protection agents and/or nutrients.

The present disclosure is generally directed to an anucleated cell-based platforms for encapsulation and delivery of agricultural compounds. Disclosed herein are compositions for the stable and targeted delivery of agricultural compounds within achromosomal and/or anucleated cells. The present disclosure also provides methods of improving encapsulation and retention of agricultural compounds in achromosomal and/or anucleated cells.

The present invention relates to a spraying assembly comprising an injection device, a first hydraulic circuit for conveying carrier liquid to a spray nozzle, the first hydraulic circuit comprising, upstream of the spray nozzle, an injection section, a second hydraulic circuit for conveying the active substance to the injection device, under an injection pressure greater than the carrier liquid circulation pressure, the injection device comprising a direct dosing interface comprising a plurality of through-holes in the injection section of the first hydraulic circuit, and the injection device further comprising at least one corresponding actuator configured to open or close each through-hole so as to allow a determined dosing of active substance to pass through at least one open hole to be injected into the carrier liquid stream.

A system and method for mixing and dispensing one or more pesticides includes a plurality of pesticide containers (5) for containing pesticide and at least one dosing device (7) associated with the pesticides containers and adapted to dose pesticide from the pesticide containers. A mixing device (9) receives pesticide from the dosing device and mixes the pesticide to form at least one of a pesticide solution and a pesticide mixture. A computer device (21) includes a processor and is adapted to receive an input from a user and based on that input operate the dosing device to dose a quantity of pesticide from one or more of the pesticide containers.

The invention relates to an agrochemicals pre-dilution unit comprising a mixing device that receives and mixes water and agrochemical. This unit carries out the mixing process by means of a plurality of pumps in fluid communication with the mixing device, which sends the prepared mixture a tank truck through outlet pipes. A plurality of bulks are installed in the unit and contain agrochemicals that are pumped in a controlled and precise manner to the mixing device, allowing a mixture of agrochemicals and water to be prepared with minimum human intervention. Also disclosed is the preparation of the liquid mixture controlled by a PLC, which enables an operator to obtain an accurate mixture without needing to intervene directly in the unit, since the operator can interact with the unit by means of a computer, such that such that the PLC controls all the devices in unit in order to prepare the mixture.

Provided is a liquid supply apparatus which is capable of directly taking in a liquid from a flow channel and appropriately mixing a gas into the liquid when generating-nanobubbles in the liquid using an ultrafine bubble generating apparatus. The liquid supply apparatus comprises a flow channel for a liquid supplied from a liquid supply source and an ultrafine bubble generating apparatus for generating nanobubbles in the liquid. The ultrafine bubble generating apparatus is provided with: a liquid ejector for ejecting the liquid taken in from the flow channel; a gas mixer for pressurizing and mixing a gas into the liquid ejected from the liquid ejector; and a nanobubble-generating nozzle for generating nanobubbles in the liquid by passing the liquid with intermixed gas therethrough. The pressure of the liquid in the flow channel flowing into the liquid ejector from the upstream-side of the liquid ejector is a positive pressure and, between the liquid ejector and the-nanobubble-generating nozzle, the gas mixer pressurizes and mixes the gas into the liquid, which is flowing in a pressurized state toward the nanobubble-generating nozzle.

An atomizer mixing chamber for a seed treater has a body having first and second inlets for receiving first and second treatment fluids. The atomizer mixing chamber has a first stage cup for receiving and combining the first and second treatment fluids to provide a combined fluid, the first stage cup comprising a first set of holes through which the combined fluid flows. The atomizer also has a second stage cup below the first stage cup for receiving the combined fluid from the first stage cup, wherein the second stage cup further mixes the combined fluid to provide a mixed fluid and wherein the second stage cup comprises a second set of holes through which the mixed fluid flows. The atomizer mixing chamber may include a third stage cup below the second stage cup for receiving the mixed fluid and having a third set of holes through which the mixed fluid exits from the atomizer.

A system and method for mixing and dispensing one or more pesticides includes a plurality of pesticide containers (5) for containing pesticide and at least one dosing device (7) associated with the pesticides containers and adapted to dose pesticide from the pesticide containers. A mixing device (9) receives pesticide from the dosing device and mixes the pesticide to form at least one of a pesticide solution and a pesticide mixture. A computer device (21) includes a processor and is adapted to receive an input from a user and based on that input operate the dosing device to dose a quantity of pesticide from one or more of the pesticide containers.

A particulate material sensing and agitation control system includes a controller with a memory and a processor, where the controller is configured to receive at least one sensor signal indicative of a measured profile of a particulate material within a storage tank of an agricultural system, determine whether a variation between the measured profile and a target profile is greater than a threshold value, and output a first output signal to a user interface indicative of instructions to inform an operator of a profile variation, output a second signal to an agitating system indicative of activation of the agitating system, or a combination thereof, in response to determining that the variation between the measured profile and the target profile is greater than the threshold value.
