Description

technical field [0001] The present invention relates to the application of a class of compounds in the preparation of insecticides, specifically 4-tert-butyl-5-(1,2,4-triazol-1-yl)-2-benziminothiazole in the preparation of insecticides application in agents. 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 Heterocylie 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 (...
