Systems and methods of use of chlorine dioxide in controlled environmental agriculture settings and postharvest applications are provided. A method can comprise application of gaseous chlorine dioxide at a level effective to prevent microbial proliferation in a setting containing growing plants. A system can comprise a chemical microorganism control agent dispersal system, an airborne microorganism detection system, and a cultivation environment monitor system.

This invention relates to a system for releasing beneficial mites and the use of such a system. Mite species that can be used beneficially for human purposes may for example be employed in the control of pests, such as in the field of agriculture, including agricultural production systems for plant products, agricultural production systems for animal products, and animal husbandry, or in the field of storage of food products. The system of the invention may find use in any of these fields.

The present invention provides a drone (unmanned aerial vehicle) capable of photographing a base part of the stem and a side of the leaf of the field crops for evaluating their growth status.

A camera directed backward with a depression angle of about 60 degrees is installed at the bottom of the drone. The camera is configured to capture an image of the crop temporarily knocked down by the downdraft created by the rotor of the drone. Since the base part of the stem and the side of the leaf are exposed to the sky, images can be appropriately captured. The depression angle of the camera may be automatically adjustable depending on the flight speed, wind force, and wind direction. Further, it is preferable to rotate the entire body so that the camera is always directed to backward when the drone changes flying directions.

A device includes an image data receiving component, a vegetation index generation component, a crop data receiving component, a masking component and a multivariate regression component. The image data receiving component receives image data of a geographic region. The vegetation index generation component generates an array of vegetation indices based on the received image data, and includes a plurality of vegetation index generating components, each operable to generate a respective individual vegetation index based on the received image data. The crop data receiving component receives crop data associated with the geographic region. The masking component generates a masked vegetation index based on the array of vegetation indices and the received crop data. The multivariate regression component generates a crop parameter based on the masked vegetation index.

The present invention has for its object to provide a composition in which a photoluminescent carbon nanoparticle having no dependency of an emission wavelength on an excitation wavelength and being enhanced in terms of quantum efficiency is dispersed, a process of producing the same, and an application of the same. The composition of the invention has a photoluminescent carbon nanoparticle dispersed in a water-soluble solvent. The photoluminescent carbon nanoparticle contains a carbon atom, an oxygen atom, a nitrogen atom, and a hydrogen atom if required. As shown in FIG. 6, the photoluminescent carbon nanoparticle has an intensity of a C—N bond and/or C—O bond-derived peak (285.98 eV) larger than that of a C—C bond and/or C—H bond-derived peak (284.95 eV) in terms of X-ray photoelectron spectroscopic spectra, and a Raman spectrum having a peak based on a G-band and a D-band.
