1-(1,2,4-triazole-1-group)ketoxime ethers and its application in preparation of bactericide

Abstract

The invention discloses 1-(1,2,4-triazole triazole-1- group)ketoxime ether or its nitrate as shown in the chemical structure formula I, wherein R<1> is selected from the group consisting of C1-2alkyl, C3-4straight chain or branched alkyl; R is selected from the group consisting of C1-C2alkyl, C3-C18 straight chain or branched alkyl or alicyclic groups; allyl, propargyl, 2-methyl allyl, 2-chlorallyl, (Z)-3-chlorallyl, (E)-3-chlorallyl, or ArCH2; or Y(CH2)n:Y equals to fluorine, chlorine, bromine or iodine, n equals to 1,2,3,4,5 or 6. The application of 1-(1,2,4-triazole triazole-1- group)ketoxime ether or its nitrate as shown in the formula I in the preparation of a bactericide for killing wheat powdery mildew or Botrytis cinerea.

Description

technical field [0000] The present invention relates to a new class of compound and its preparation method and application, specifically 1-(1,2,4-triazol-1-yl)ketoxime ether, its preparation method and its application as a fungicide. Background technique [0000] Triazole compounds have high activity of fungicide, herbicide, insecticide and plant growth regulation, and become one of the most promising pesticides because of their dual functions of sterilization and growth control [Recent development of foreign fungicides. Pesticides, 1989, 28(1):48. ] Oxime ether compounds also have excellent insecticidal, acaricidal, bactericidal, herbicidal, detoxification, synergistic and other biological activities, most of which have the characteristics of high efficiency and low residue, and are widely used in pesticides. Since the discovery of the first oxime ether fungicide Cymoxan in 1974, active compounds related to this type of structure have been emerging [Research progress of ox...

AI Technical Summary

Problems solved by technology

[0000] Existing triazole fungicides generally have shortcomings such as single action mechanism and action site, water insolubility, and limited control range. The introduction of oxime ether active groups and making some compounds into nitrates can not only strengthen the biological activity of each other function, and solved the water solubility problem of triazole compounds
