Abstract
The application of leidinmycin compounds in inhibiting plant pathogenic fungi and preventing and treating plant diseases belongs to the technical field of pesticide fungicides. In order to screen leidinmycin compounds capable of being used for preventing and treating plant diseases caused by plant pathogenic fungi or plant pathogenic oomycetes, five kinds of leidinmycin compounds are used for inhibiting plant pathogenic fungi and preventing and treating plant diseases. The leidinmycin compounds have strong inhibitory effect on plant pathogenic fungi, including the growth of fungal hyphae in Sclerotinia, Rhizoctonia, Elsinoe, Botrytis and Alternaria and the growth of oomycete hyphae in Pythium, Peronospora and Pseudomonas. In addition, the leidinmycin compounds have good prevention and treatment effect on plant diseases caused by the above plant pathogenic fungi and plant pathogenic oomycetes, and have no toxic side effect on plants, and can be developed and applied as effective components of pesticides or plant pathogenic fungicides.
