Nitrile azole, also known as carbazole and benzonitrile, is a triazole systemic bactericide that prevents germinating spores from invading crop tissue and inhibiting the elongation of hyphae. It can be used in the incubation period of the bacteria to prevent the development of the pathogen; after use, it can deform the next generation of spores, lose the ability to infect, and have a preventive and therapeutic effect on the disease.
