An apparatus for efficient targeting or removal of weeds or other plants. The apparatus may include a vehicle having a frame, a motor and a plurality of ground engaging members adapted to propel the vehicle over a surface. It may also include a robotic arm comprising a distal portion and a proximal portion coupled to the frame, and an implement, such as a tool or hoe connected to the distal portion of the robotic arm. The implement can be raised and lowered, and also moved relative to the surface by the robotic arm by pivoting or rotating the robotic arm at or near the proximal portion.

An agricultural sprayer includes a nozzle assembly having a nozzle body, a valve moveably positioned within the nozzle body, and an actuator configured to move the valve within the nozzle body. Additionally, the agricultural sprayer includes a computing system having a spray controller positioned outside of the nozzle body and a nozzle controller positioned within the nozzle body. The spray controller is communicatively coupled to the nozzle controller such that the spray controller is configured to transmit control signals to the nozzle controller via a first communicative link, with the nozzle being controller configured to control an operation of the actuator based on the control signals received from the spray controller. Moreover, the spray controller is communicatively coupled to the actuator such that the spray controller is configured to directly control the operation of the actuator via a second communicative link independently of the nozzle controller.

A product system for an agricultural sprayer includes a product tank configured to store a volume of an agricultural product. A fill station is configured to accept the agricultural product from an off-board source. A flow assembly is fluidly coupled with the fill station and is configured to direct the agricultural product into a product tank from the conduit. A reclaim system is configured to provide the agricultural product within the flow assembly to the product tank. A computing system is communicatively coupled to the reclaim system. The computing system is configured to receive inputs indicative of activation of a fill mode, detect termination of the fill mode, and activate a reclaim mode to move the agricultural product from at least the conduit to the product tank through activation of the reclaim system.

A flow rate sensor system for an agricultural sprayer includes a drum housing and a central passage housing defining a flow path, a Hall-effect sensor, a Hall-effect sensor window in a display housing, a magnetic carrier within the drum housing, and a magnet positioned in the magnetic carrier. The flow path has a first portion generally parallel to an axis, and a second vortex portion around the axis. The Hall-effect sensor faces the axis. The Hall-effect sensor window is between the Hall-effect sensor and the axis. The magnetic carrier is configured to rotate about the axis. Related methods are also disclosed.

An optical flow rate sensor system for a sprayer includes an optical sensor, an optical sensor window within a display housing, a projectile within a drum housing, and vortexing geometry upstream of the projectile. The optical sensor is located adjacent to the optical sensor window. The projectile includes a first section having a first optical absorption value and a second section having a second optical absorption value that is lower than the first optical absorption value. The projectile is configured to revolve around an axis of the drum housing.

Described herein are implements and applicators for placement of fluid applications with respect to agricultural plants of agricultural fields. In one embodiment, a fluid applicator includes at least one applicator arm, a first nozzle disposed to apply fluid to a rhizosphere of the plants, and a second nozzle disposed to apply fluid between the row of plants.

An apparatus for spraying flowable media and in particular plant protection agents onto plants, has at least a first spray unit and a second spray unit wherein each of the spray units has a tubular conduit unit that extends in a predetermined longitudinal direction and is suitable and intended for conducting a flowable plant protection agent, and wherein each of the spray units has at least one spray head that is in flow communication with the conduit unit associated therewith. The spray units are provided in a pivotable manner in relation to a predetermined pivot axis on a carrier, and the apparatus has an adjustment unit that allows both the first spray unit and the second spray unit to be pivoted between a working position and an idle position.

Disclosed are compositions comprising compounds of Formula (I) and compounds of Formula (II). Also disclosed are N compositions containing compounds of Formula (I) or compounds of Formula (II), or combinations thereof and methods for controlling an invertebrate pest comprising contacting the invertebrate pest or its environment with a biologically effective amount of a compound or a composition of the disclosure.

A spraying work method includes generating a target route for a work vehicle that performs a spraying work on crops arranged in a plurality of rows in a field, causing the work vehicle to autonomously travel along the target route, and switching a spraying direction of a spray material for the crop by spraying units and provided in the work vehicle in accordance with a position of either the crop on a work route, on which the work vehicle performs the spraying work while autonomously traveling, or the crop adjacent to the work route.

A spraying machine includes a machine body, a support frame, and a spraying portion. The support frame includes a horizontal frame having a length along a left-right direction, and a pair of vertical frames and each having a length along an up-down direction, and protruding downward from both ends of the horizontal frame. The spraying portion is supported by the support frame, and sprays a spraying material. The support frame is supported by the machine body to be rotatable around a rotation axis passing through a fulcrum portion provided on the horizontal frame and extending along a front-back direction, while maintaining a relative positional relationship between the pair of vertical frames and the horizontal frame.
