Microbicidal compositions and methods using combinations of propiconazole and N-alkyl heterocycles and salts thereof

Abstract

A method for increasing the effectiveness of the microbicide propiconazole, (RS)-1-2-[(2,4-dichlorophenyl)-2-propyl-1,3-dioxalan-2ylmethyl]-1H-1,2,4-triazole, is described. In the method, propiconazole and a potentiator, an N-alkyl heterocyclic compound, its salt, or a mixture thereof, are applied to a substrate or aqueous system subject to the growth of microorganisms. The N-alkyl heterocyclic compound, its salt, or a mixture thereof is applied in an amount effective to increase the microbicidal activity of the microbicide. The N-alkyl heterocyclic compound has the formula:The variable "n" ranges from 5 to 17, and the heterocyclic ring defined byis a substituted or unsubstituted ring having four to eight members. Microbicidal compositions are described where propiconazole and an N-alkyl heterocyclic compound, its salt, or a mixture thereof are present in a combined amount: effective to control the growth of at least one microorganism. Methods for controlling the growth of microorganisms on various substrates and in various aqueous systems are also described. The combination of propiconazole and an N-alkyl heterocyclic compound, its salt, or a mixture thereof is particularly useful as microbicidal in the leather industry, the lumber industry, the papermaking industry, the textile industry, the agricultural industry, and the coating industry, as well as in industrial process waters.

Description

field of invention [0001] The present invention relates to compositions and methods for controlling the growth of microorganisms on various substrates and in aqueous systems. More specifically, the present invention relates to propiconazole, also known as (RS)-1-[2-(2,4-dichlorophenyl)-4-propyl-1,3-dioxolane-2 -Alkylmethyl]-1H-1,2,4-triazole, and the composition of N-alkyl heterocyclic compound, its salt or its mixture, wherein, N-alkyl heterocyclic compound, its salt or its mixture Enhanced microbicidal activity of propiconazole. Background of the invention [0002] A large number of commercial, industrial, agricultural and wooden materials or products are susceptible to attack or degradation by microorganisms, which reduces or destroys their economic value. Examples of such materials or products include surface coatings, wood, seeds, plants, leather and plastics. The various temperatures at which the aforementioned materials or products are manu...
