Paragraph 0090-0092, (2017/11/16)
The invention discloses a compound shown in general formula I and an application thereof as a plant disease-resistant activator, wherein R1 is independently selected from hydrogen, C1-C6 alkyl, C1-C6 halogenated alkyl, C3-C6 naphthenic base, halogen, nitro and hydroxyl; R2 is independently selected from C1-C6 alkyl, C1-C6 halogenated alkyl, hydroxyl, C1-C6 alkoxy, C1-C6 halogenated alkoxy, substituted or unsubstituted C6-C14 aryl, halogen, nitro, amino, C1-C6 alkoxy, carboxyl, C1-C3 alcoxyl formyl and pentabasic or hexahydric nitrogen and heterocyclic ring of oxygen or sulfur-containing; n is selected from 0-5. The compound is used for inhibiting the pathogens through inducing the plants to generate disease resistance, rather than directly killing or inhibiting the pathogens; the compound has the advantages of systematicness, long-lasting effect, broad spectrum and safety, so that the dosage of highly toxic pesticide can be reduced, and environment friendliness, great industrial/commercial prospect and market value are achieved.
