An improved underground fumigation method and system including a plurality of elongated pipes placed underground adjacent to a building structure, each having a series of apertures therethrough adapted to allow fumigation liquids and gases to pass along a length thereof and outwardly through the apertures. Each elongated pipe includes an external blockage preventing half-pipe attached along a substantial portion of the length of the elongated pipe and includes a series of apertures therethrough adapted to align with the apertures of the elongated pipe. A main control box is included and attached to each elongated pipe and controls the flow of fumigation liquids and gases therethrough. Furthermore, a fumigation liquid and/or gas supply tank is provided and connected to the main control box and adapted to provide fumigation liquids and/or gas to the underground fumigation system.

Embodiments of systems and approaches for managing post-harvest crop quality and pests are described. Such a system may include a plurality of edge devices each comprising sensor components and collectively forming a mesh network, for measuring the local physical environment within stored crops and, for example, transmitting the measurements to a service from within the crop storage area. In certain embodiments, such a system may be used to manage post-harvest crops and storage areasfor example, approaches are described for determining fumigation treatment duration, determining phosphine dosage, determining heat treatment duration, and determining safe storage time for crops.

A fogger comprises a blower tube having a passageway, a fan configured to rotate to generate an airflow through the passageway, a reservoir configured to hold a volume of fluid and a volume of air, an air pump in fluid communication with the fluid in the reservoir, a motor configured to drive the fan and the air pump, an atomizing valve, a dispensing line fluidly coupling the atomizing valve to the passageway, a liquid tube fluidly coupling the fluid in the reservoir to the atomizing valve, and an air escape line fluidly coupling the air in the reservoir to the atomizing valve. In response to the air pump providing a stream of compressed air to the reservoir, air moves through the air escape line from the reservoir to the atomizing valve, such that fluid is drawn through the liquid tube and into the atomizing valve to be atomized.

A scent vaporizing and distribution device uses an electric heating element to rapidly vaporize a liquid scent material. An airflow generator is used to create a distribution airflow that distributes the vapor from the device. The airflow generator can be an electric-powered fan or a manually-powered pump or squeezable bladder. The liquid scent material can include a glycol or a water-glycol mixture. A scent material such as liquid or powdered deer urine or a pleasant scent that can be used as a room or automobile or room freshener is mixed with the liquid. The vapor generator can be removable and replaceable such that different scents can be used with a single airflow generator or an empty generator can be replaced.

The present invention relates to a chemical product control and metering equipment for agricultural land disinfection machines with at least two receptacles for containing chemical products and an injector for injecting the products on agricultural land, comprising a product metering frame, a control panel of the metering frame, wirelessly connected thereto, and an electronic control card. The metering frame comprises a chemical product inlet duct, an electrovalve and a dose control flowmeter connected to the inlet ducts and to a hydraulic pump, which has at least one product outlet duct. The electronic control card is arranged inside the metering frame and is connected to the motor, the dose control flowmeter, and the electrovalves.

A fogging machine includes a blower assembly that includes an electric motor and a turbine coupled to the electric motor and configured to generate an airflow. A conduit is connected to the blower assembly and terminates at a conduit outlet. The conduit is configured to permit an operator to direct the airflow at a desired location. A liquid assembly is connected to the blower assembly for emitting a liquid in the airflow to create a mist. A support assembly permits the fogging machine to be carried by an operator.

Devices, systems, and methods for releasing active ingredients, including volatile active ingredients, are described. The active ingredients may be released for agricultural applications prior to, during, and/or after harvest of produce. In some instances, the devices, systems, and/or methods promote relatively rapid release of active ingredients from a bed containing a porous and solid delivery material (e.g., a particulate material) via direction of gaseous fluid flow through the bed. For example, a pump (e.g., a fan) connected to a housing comprising the bed may propel gas (e.g., air) through the bed, thereby inducing, maintaining, and/or accelerating release of the active ingredient. In some embodiments, the devices, systems, and/or methods described herein facilitate fast, safe, and efficient fumigation of agricultural and/or horticultural products with active ingredients, before, during, and/or after their harvest.

A circulation chamber for a cargo container comprises a cargo container extension including a housing, a cargo container aperture, and an interior volume; the cargo container extension is structured and dimensioned to be attached to an opening of the cargo container, thereby placing the interior volume in fluid communication with an interior of the cargo container. The housing, cargo container aperture, and interior volume may be cooperatively structured and dimensioned to allow at least a portion of the cargo container to be disposed in sealing engagement with the cargo container aperture, and furthermore, allow, at least partially, a door of the cargo container to be open while the circulation chamber is attached to the cargo container.
