Antimicrobial compositions for killing or deactivating microbes, such as viruses, bacteria, or fungi, include metal nanoparticles, a carrier, and a plurality of metal nanoparticles. The nanoparticles can be selected to have a particle size and particle size distribution to selectively and preferentially kill one of a virus, a bacterium, or a fungus. Antiviral compositions can include nanoparticles having a particle size of 8 nm or less, 1-7 nm, 2-6.5 nm, or 3-6 nm. Antibacterial compositions can include nanoparticles having a particle size of 3-14 nm, 5-13 nm, 7-12 nm, or 8-10 nm. Antifungal compositions can include nanoparticles having a particle size of 9-20 nm, 10-18 nm, 11-16 nm, or 12-15 nm.

Disclosed is a sanitary ware having not only a practical antivirus property but also a property which allows a pollution to be difficultly attached to, and to be easily removed from the sanitary ware. A sanitary ware comprising a pottery substrate and a glaze layer formed on a surface of the pottery substrate, wherein the glaze layer contains a metal element as an antivirus agent, and the metal element is present in a state of a spinodal phase separation in at least a surface region of the glaze layer, has a practical antivirus property as well as a property which allows a pollution to be difficultly attached to, and to be easily removed from, the sanitary ware.

A method of treating a leguminous plant crop comprises a step of applying a 2-chloroethylphosphonic acid solution to the leguminous plant once a seed stage is observed. The solution of 2-chloroethylphosphonic acid may comprise nitrogen and zinc. The 2-chloroethylphosphonic acid solution may also comprise a spreader-sticker. Application of the 2-chloroethylphosphonic acid solution shortens plant maturation and significantly reduces the timing to reach a harvesting stage.
