A controller is operatively connected to a dispensing system and configured to change the dispensement of an agricultural input from the dispensing system in different predetermined locations within at least one predefined test plot in a management zone of an agricultural field. The predetermined locations have been randomized and replicated for quantifying the agronomic response in a statistically valid manner.

A spreader device includes a hopper axially mounted above a generally circular hollow tube, the generally circular hollow tube forming a semi-circular hopper floor of an interior area formed by the hopper, and a drive motor assembly attached to the hopper and operable to rotate the generally circular hollow tube within at least a portion of the interior area formed by the hopper.

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 powdered scent compound and related methods of application for adhering the powdered scent compound to a desired application area. The powdered scent compound can comprise a porous carrier powder, an adhesive compound and a synthetic scent compound. The powdered scent compound is shelf-stable and convenient to apply, carry and store. Furthermore, the powdered scent compound can adhere to applied surfaces, thereby ensuring that powdered scent compound remains where it is applied, even in locations where the potential exists for the compound to drip or be blown from.

Systems and methods for extermination of ants may provide for the introduction of powder insecticide directly into an ant colony to deliver maximum saturation throughout the colony chambers or tunnels. Ants within the colony may track through the insecticide, and the insecticide may contaminate the ants' food source within the colony, thereby exterminating the ants with minimal disturbance to people or animals.

An agricultural distribution device includes a plurality of spreading elements arranged on a distribution linkage and adapted to spread granular material on an agricultural land, a detection device adapted to detect plant rows on the agricultural land, an adjustment device configured to change an impact area of the granular material dispensed by one or more of the spreading elements on the agricultural land during a spreading process, and a control device which is adapted to control the adjustment device as a function of the plant rows on the agricultural land detected by the detection device during the spreading process.

A system for dispensing liquid agricultural products with seed includes a control system; a seed transport mechanism; an agricultural product supply system; and, a seed brush assembly. The seed transport mechanism is affixed to a seed planter row unit. The agricultural product supply system is configured to dispense agricultural products in response to an output signal from the control system. A brush housing structure of the seed brush assembly receives seed from the seed transport mechanism. A brush of the seed brush assembly has bristles positioned within the brush housing structure. The agricultural product supply system is configured to dispense the liquid agricultural products onto the bristles. The bristles are configured to minimize the resistance associated with the passage of seed past the wetted bristles. The liquid agricultural product is transferred from the brushes onto the seed as the seed is dispensed prior to the seed hitting the ground.

The invention provides a pneumatic conveying system having a series of supply lines with at least portions of the lines being wear resistant to extend the useful lifespan of an agricultural product delivery applicator. The wear resistant supply line(s) may be made from a hard material and have a curve(s) defined by angled or mitered segments that are welded or otherwise joined to collectively provide the curve(s) The wear resistant supply lines may be at least partially reinforced by way of, for example, welded or other build up wear resistant material(s) at high wear zones of the supply lines.

A method for applying beta-ocimene in an open space includes using loose porous material with a particle size of 0.6-10 millimeters as a adsorption carrier, uniformly mixing 1 liter of beta-ocimene with 5-20 kilograms of the carrier to obtain a mixture, and storing and transporting the mixture under a sealed condition; and directly sprinkling the mixture to the plants in the open space by means of uniform sprinkling mode or point-distributed sprinkling mode when in use.
