With the strengthening of environmental protection concepts and the implementation of sustainable development strategies, high efficiency, low toxicity, high activity and low residue have become an inevitable trend in the development of pesticides . Whether crops can grow healthily is not only affected by diseases, but also the prevention and treatment of diseases .

In recent years, the fungicides developed abroad have mainly systemic and selective properties. However, non-systemic fungicides with a wide spectrum of sterilization are still prolonged, such as copper, dexame , chlorothalonil, etc. .
In short, the unique mechanism of fungicides and broad-spectrum efficiency has become the focus of recent development in the world. There are three general directions: one is the new fungicide developed for the resistance of pathogens; the other is the unique role of the development of natural products as lead compounds. A new fungicide for the mechanism; the third is a plant activator for enhancing the crop's own immunity to disease. Among them: triazole fungicide has a broad spectrum, systemic absorption, has a preventive effect on diseases caused by ascomycetes, deuteromycetes, basidiomycetes, etc., and is suitable for apple, pear, grape, sugar beet, corn, rape and the like.
