A method of manufacturing an antiviral fiber product includes impregnating a virus-inactivating agent into a cellulose-based fiber at a temperature of 120° C. to 200° C. and a pressure of 0.0098 MPa to 0.59 MPa. The virus-inactivating agent contains: an aqueous organic acid solution containing 40 wt % to 50 wt % of organic acid partially lactonizing when dissolved in water; zinc oxide nanoparticles dispersed in the aqueous organic acid solution; and zinc salt of organic acid generated by dispersion of the zinc oxide nanoparticles into the aqueous organic acid solution.

A process for the preparation of an antimicrobial coating solution is described. The process comprises the steps of: (i) mixing a chelating agent with titanium alkoxide and fluoroacetic acid; and (ii) adding an aqueous solution to the mixture from step (i). The antimicrobial coating described is visible light activated. The coating is applied to surfaces and then heat treated to form a transparent layer on the surface. This is particularly advantageous where the surface is glass.

A method for controlling insect pests on a plant is provided. The method includes applying to the plant and/or to the insect pests a combination comprising: a nitrogen-bearing macrocyclic compound which is a photosensitizer that generates reactive oxygen species in the presence of light, the photosensitizer being selected from the group consisting of a porphyrin, a reduced porphyrin and a mixture thereof; and a chelating agent which is an aminopolycarboxylic acid compound or an agriculturally acceptable salt thereof; and exposing the plant to light in the presence of the insect pests to activate the nitrogen-bearing macrocyclic compound and generate reactive oxygen species.
