Provided are a biodegradable sheet with antiviral properties, a manufacturing method thereof, and the use thereof. The biodegradable sheet comprises: a biodegradable polymer resin consisting of a polylactic acid-based polymer; or a composite degradable polymer resin comprising of a biodegradable resin and a petrochemical resin; and particles of an inorganic antiviral agent or aggregated composite particles of at least two inorganic antiviral agents incorporated into the biodegradable sheet so that the inorganic antiviral agent can be dispersed with a particle size of 100 to 900 nm.

Disclosed are micronutrient chelate compositions and methods that provide nutrients to a plant to improve growth while controlling pathogens, such as Candidatus Liberibacter asiaticus the causal pathogen for citrus greening disease, by improving plant health through the enhancement of beneficial microbial populations resident in the plants phloem. The chelate compositions include a combination of a metal, such as iron, and a derivative of a chelating agent such as EDDHA or HBED. The chelate formulations can either be a dry formulation or liquid formulation that is dispersed in a selected amount of water and applied to the foliage of a plant and/or applied to the soil proximal to the plant rhizosphere.

Methods for disinfecting a surface are provided which include contacting a surface with a solution comprising Fe(VI)O.sub.4.sup.2−, thereby disinfecting the surfaces. In some cases, the surface to be contacted with the solution is in a space suitable for human occupancy and the surface is arranged in the ambient of the space. In addition, solutions comprising Fe(VI)O.sub.4.sup.2− are provided. The solutions may additionally include a hypohalite salt and a surfactant.

The present disclosure describes agrochemical water immiscible solvent-in-water (e.g., oil-in-water) emulsion formulations that include one or more agrochemical active agent(s), a continuous aqueous phase containing a sulfo polymer, and a discontinuous water immiscible phase substantially homogenously incorporated in the aqueous phase, and optionally a rosin. The present disclosure also describes methods of making and using such emulsion formulations in agriculture.

A method of preparing iron oxide nanoparticles using an herbal mixture comprising Capparis spinosa, Cichorium intybus, Solanum nigrum, Cassia occidentalis, Terminalia arjuna, Achillea millefolium, and Tamarix gallica. The method produces crystalline γ-Fe.sub.2O.sub.3 nanoparticles which are superparamagnetic. The iron oxide nanoparticles are used in a method of killing or inhibiting the growth of a bacteria and/or fungus, particularly in the form of a biofilm. The nanoparticles are also used in a method of treating colon cancer.
