A method of preparing a disinfecting composition comprising charged polyethylenimine (PEI), the method comprising adding a base to an aqueous solution comprising a linear PEI hydrochloride solution to provide a linear PEI salt solution with a pH between 9-11, adding a first organic acid to reduce the pH to less than 7, removing about 20% to 100% of the salt from the solution, and optionally adding water and/or a second organic acid to obtain the disinfecting composition with a pH of 2-7. The method can further comprise adding at least one metal salt to the disinfecting composition. The resulting disinfecting solution can be used to provide antimicrobial products with enhanced antimicrobial performance, reduced toxicity, and/or able to leave a persistent “kill-later” film.

The present disclosure relates to an assay method for the antimicrobial activity of an antimicrobial agent. The assay method for the antimicrobial activity of an antimicrobial agent according to the present disclosure comprises: injecting an antimicrobial agent into a culture medium in which a strain is grown; shaking the culture medium according to time and sampling the culture medium according to the time; after the sampling, centrifuging the culture medium into which the antimicrobial agent is injected; and after the centrifuging, measuring the number of microorganisms after culturing a bacterial solution from which the antimicrobial agent is removed, wherein the antimicrobial activity can be evaluated depending on the type and content of the antimicrobial agent, and the antimicrobial activity of the antimicrobial agent can be accurately and reliably evaluated.

The present invention relates to a novel agricultural pesticidal composition. In particular, the present invention provides a pesticidal composition comprising combination of an insecticide and plant health promoting agent. The said combination is highly suitable for controlling unwanted animal pests, such as insects, acaricides and/or nematodes, and unwanted phytopathogenic fungi.
