A convenient effective means is provided to eliminate the lawn pest known as ground pearl (Margarodes spp), a subterranean member of the scale family, that is immune to chemical lawn treatment applications.

This, electrically equipped, hand propelled, device is simply pushed back forth over and around on the turf areas where pearl damage is evident. The design's 4 caster wheels provide an independently sprung suspension permitting close ground clearance during operation insuring full personal safety when used properly.

The design utilizes a magnetron to provide high frequency electromagnet wave energy that is fully confined and directed only strait down into the earth via a one wave length long strait wave guide that maximizes the E field at ground level. From there the wave radiates into the earth hemi spherically with the familiar strength loss as the square of the distance. Fortunately, pearl live close to the surface where they are vulnerable.

The microwave frequency band used is not high enough to be an ionization radiation threat to people or pets. It can however lethally damage the subject organism by agitating the pearl's internal water molecules despite its protective covering.

System for the disinfection of agricultural soil includes an electric energy source, at least one radiofrequency or microwave generator connected to the electric energy source and arranged to convert the electric energy into electromagnetic power and a plow-like electromagnetic applicator connected to the radiofrequency or microwave generator via wave-guiding lines, the plow-like electromagnetic applicator being arranged to be inserted into the soil so as to transmit the electromagnetic power to the soil, thus obtaining a disinfection of the soil.

A weed burner includes a main body and handle, the main body including base and operating portions, the base portion connects to the handle, the operating portion projecting forwardly from the base portion; the operating portion includes an arcing chamber for letting in a plant and an electrode assembly for discharging high-voltage arcs to the plant, the arcing chamber extending through the operating portion, a bottom end of the arcing chamber being opened and located at an underside of the operating portion; and the electrode assembly includes a positive electrode and a negative electrode, the positive electrode being disposed in the operating portion and tilting downward into the arcing chamber, the negative electrode being disposed at an underside of the operating portion and surrounding an opening of the bottom end of the arcing chamber.

An electrical apparatus to kill a plant or at least attenuate plant growth, the apparatus comprising: an power supply unit; an applicator unit comprising an applicator electrode; an return unit comprising an return electrode; electrical circuitry; the power supply unit arranged to apply electrical energy through a transmission circuit comprising the applicator electrode, and the return electrode, wherein said electrical circuitry implements a detection system to determine a condition of electrical arcing of the electrical energy from one or both of said electrodes, the electrical circuitry arranged to control the electrical energy through the transmission circuit to at least partially reduce the electrical arcing based on said determined condition of electrical arcing.

Various embodiments of an apparatus, methods, systems and computer program products described herein are directed to an agricultural treatment system and method of operation. The agricultural treatment system uses a spraying apparatus for spraying fluid at agricultural objects. The spraying apparatus is configured with a spraying head assembly that includes a moveable spraying head with one or more spraying tips a first motor assembly having a first motor interconnected with the spraying head assembly, wherein the one or more spraying tips pivot and rotate about an axis via a rotation of the first motor to emit a first fluid of the one or more fluids at the agricultural objects.

A method for plant treatment, including: receiving a first measurement for a plant from a sensor as the sensor moves within a geographic area comprising a plurality of plants; in response to receipt of the first measurement and prior to receipt of a second measurement for a second plant of the plurality, determining a set of treatment mechanism operation parameters for the plant to optimize a geographic area output parameter based on the first measurement and historical measurements for the geographic area; determining an initial treatment parameter for the plant; and operating a treatment mechanism in a treatment mode based on the set of operating parameters in response to satisfaction of the initial treatment parameter.

An apparatus, method and system for eradicating soil-borne pests in soil utilizing leading and trailing rows of shanks, a source of electricity and a mechanism to determine the condition of the soil being treated. The leading row has ripper shanks that open a path through the soil and the trailing row has specially configured electrically conductive stinger shanks, connected to the source of electricity, that discharge electricity into the soil to electrocute pests. The soil condition determination mechanism comprises one or more soil probes in a probe row disposed between the leading and trailing rows. The soil probe reads the condition of the soil in the path cut by the ripper shanks and transmits a signal to a voltage controller that is connected to the source of electricity to adjust the output thereof to the stinger shanks to automatically compensate for changing soil conditions to effectively and efficiently eradicate pests.

The present invention provides relates to a device for introducing high voltage into a plant substrate, the device arranged to be carried by a moving carrier. The device comprises at least two conductive electrodes; at least one pair of insulating guides connected to the at least two conductive electrodes, insulating the electrodes from each other and at least one of them from the moving carrier; at least one connector for attaching the insulating guides into the moving carrier; conductive means for conducting energy from an electrical source to the at least two conductive electrodes.
