Abstract:

Plant derived fungicides utilize the natural active ingredients and their derivatives contained in plants to kill or inhibit plant pathogens. They have the advantages of biodegradability, environmental friendliness, and are effective through multiple mechanisms without easily developing drug resistance. Therefore, they have received widespread attention and become one of the hotspots in the research of new pesticides. This article retrieved the approval status of plantderived fungicides from the China Pesticide Information Network, summarized the registration information of plant derived fungicides in China from January 2009 to August 2023, sorted out the active ingredients, structural characteristics, and mechanisms of action of different types of plant derived fungicides, and summarized the formulation, application methods, and dosage characteristics of the products. We have systematically sorted and analyzed the basic situation of existing registered plant derived fungicides, which provides inspiration for exploring novel plant derived fungicidal active ingredients in the future, and also indicates directions for the development of related new pesticide products and technologies.
