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

Abstract

An improved microbicide propiconazole, (RS)-1-[2-(2,4-dichlorophenyl)-4-propyl-1,3-dioxolane-2-ylmethyl] -1H-Method of microbicidal efficacy of 1,2,4-triazole. In this method, propiconazole and a synergist, an N-alkyl heterocyclic compound, a salt thereof or a mixture thereof, are applied to a matrix or aqueous system that is prone to microorganisms. The dosage of N-alkyl heterocyclic compound, its salt or its mixture can effectively improve the microbicidal activity of the microbicide. N-alkyl heterocyclic compounds have the structure of formula (I), CH3-CnH2n- (I), where the parameter n is 5-17, and the heterocyclic ring defined as (II) is a substituted or unsubstituted 4-8 membered ring. The present invention describes microbicidal compositions wherein propiconazole and an N-alkyl heterocyclic compound, a salt thereof, or a mixture thereof are present in a total amount effective to control the growth of at least one microorganism. Methods of controlling microbial growth on various substrates and in various aqueous systems are also described. In the leather industry, wood industry, paper industry, textile industry, agricultural industry, coating industry and industrial process water, the microbicidal composition of propiconazole and N-alkyl heterocyclic compounds, their salts or their mixtures is particularly useful. Microbicides.

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...
