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 method of generating a low-CFM fog with a portable, battery-powered fogging apparatus is provided. Airflow is initiated through at least one passageway of fogging apparatus with a DC powered blower motor receiving power from at least one battery. A quantity of pressurized fogging liquid is expelled through a nozzle positioned proximate to an opening within a mixing chamber, wherein the quantity of pressurized fogging liquid exits the nozzle with at least 90% of an atomized micron particulate size between 5 and 60 microns. The expelled quantity of pressurized fogging liquid is atomized with the airflow to produce a fog at 190 CFM and at a velocity of less than 190 MPH.

An apparatus for vaporizing a chemical agent and delivering the chemical agent as a fumigant to an area requiring treatment is disclosed. The vaporizing apparatus includes a heater in fluid communication with a gas stream. A mixer is in fluid communication with a chemical agent stream. The heater heats gas to produce a hot gas stream. The hot gas stream is directed to the mixer whereby the hot gas stream contacts the chemical agent stream, vaporizing at least part of the chemical agent stream. A method of treatment using the apparatus is also disclosed.

The invention relates to a fumigant formulation comprising a mixture of ethyl formate dissolved in supercritical carbon dioxide.

A portable fogger apparatus includes a portable fogger body having at least one airflow passageway. A DC blower motor is connected to the fogger body proximate to the airflow passageway and receives power from a battery, wherein the DC blower motor produces an airflow through the passageway. A mixing chamber is positioned along the at least one passageway, wherein at least a portion of the airflow is movable through the mixing chamber. A quantity of pressurized fogging liquid is housed within a container connected to the fogger body. The pressurized fogging liquid is dispensable from the container into the mixing chamber where it is expelled through a nozzle and mixed with the airflow to produce a fog. The fog has an atomized micron particulate size between 5 and 60 microns. An activation switch controls activation of the DC blower motor and/or dispensing of the pressurized fogging liquid.
