The present application provides powder metal ion disinfectant compositions, methods for preparing powder metal ion disinfectant compositions, and methods of disinfecting an article and/or maintaining the pathogenic sterility of the article using the solid powder metal ion disinfectant composition. These solid powder disinfectant compositions are light stable heat stable, non-toxic, and non-corrosive, achieve a greater than 99% kill rate of a variety of pathogens for up to 60 days on a variety of surfaces, and do not contain nanoparticles.

Provided is a particular form of natamycin that shows improved properties as a fungicide for use in agricultural applications. A preferred natamycin composition comprises a structuring agent and a surfactant. Said natamycin composition further comprises cellular matter from a natamycin-producing organism. The natamycin in a natamycin composition preferably has a surface area of less than 6 m.sup.2/g, and an average particle size of less than 6 micrometer. The invention further relates to methods, comprising contacting a plant or part thereof, a fungus, a fruit, a crop, a seed, and/or a soil with a natamycin composition of the invention.

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.
