Quat-free surface treatment powders comprising a peroxide source, an acyl group donor and an alkalinity source are used to disinfect and/or sanitize hard surfaces. The surface treatment powders can be applied to a hard surface and left there for a period of time. The surface treatment powders are ambient moisture activated, which means that they can generate peracetic acid when a portion or all of the powder that is on the hard surface adsorbs water from the atmosphere. In addition or alternatively, the surface treatment powders are activated, i.e., generate peracetic acid through the incidental or purposeful addition of liquid thereto.

The present invention aims to provide an antiviral agent that is safe to a human body, and provides an antiviral agent comprising a titanium phosphate compound, a silicic acid compound, a silver compound, and a copper compound.

A ceramic composition includes an antimicrobial glass composition that includes components harmless to the human body and maintains an antimicrobial function semi-permanently. Specifically, the ceramic composition includes a novel antimicrobial glass composition that includes a glass former SiO.sub.2 as a main component, and ZnO and SnO as antimicrobial components.

Compositions and method for producing a systemic acquired response (SAR) in plants. The resulting SAR may improve plant health and corresponding yields. In an example, the composition comprises a base solution and an effective amount of chitosan (Aspergillus niger) (e.g., in an amount of about 0.04 wt % of the composition). The base solution may include organic material, vitamin K compound, and nitrogen. Additionally or alternatively, the composition may include adding to the composition at least one of potassium, phosphorus, or an acidic organic polymer. Still further, the composition may include a micronutrient comprising at least one of boron, calcium, copper, iron, manganese, sulfur, silicon, or zinc. The composition may be applied as a foliar spray or used to irrigate the plant.
