Abstract

The invention discloses application of 4-alkyl-5-(1,2,4-triazole-1-yl)-2-benzyl imino thiazole in the preparation of weedicide. The 4-alkyl-5-(1,2,4-triazole-1-yl)-2-benzyl imino thiazole is shown in the chemical structural formula I; and in the formula I, R is selected from CI-2 alky, C3-4 straight-chain and branched-chain alkyl, and Ar is selected from phenyl or substituted phenyl.

Description

technical field [0001] The present invention relates to the application of a class of compounds in the preparation of herbicides, specifically the use of 4-alkyl-5-(1,2,4-triazol-1-yl)-2-benziminothiazole in the preparation of herbicides application. Background technique [0002] Azole heterocyclic derivatives have always been paid attention to by drug and pesticide workers because of their good biological activity, high drug efficacy, wide bactericidal spectrum, and good systemic property [Comperhensive Heterocylic Chemistry. Pergamon Oxford, 1983, 5: 733-735], and triazoles are one of the more influential ones. The bactericidal mechanism of triazole fungicides is to affect the formation of fungal cell walls by hindering the biosynthesis of fungal ergosterol, and have good control effects on most fungal diseases that endanger crop growth. Triazole fungicides also have certain plant growth regulating activity [Pesticides, 1994, 33 (4): 19-20; J Med Chem, 1996, 39 (12): 842...
