In order to find the biorational pesticides, we have synthesized two series of daphneolone analogues including 5-methylfuryl chalcones and 5-nitrofuryl chalcones by optimizing daphneolone analogues from Stellera chamaejasme L with the good insecticidal properties of Qinghai-Tibet Plateau. All the synthesized compounds have been evaluated for anti-plant pathogenic fungi activities. The bioactivity assay showed that some of these daphneolone analogues were potentially active against plant pathogenic fungi, Rhizoctonia solani, Gibberella zeae, Bipolaris maydis, Sclerotia sclerotium and Botrytis cirerea, while the most potent 1-(2,4-dichlorophenyl)-3-(5-methylfuran-2-yl)propenone (compound 7) in this study showed good inhibitory activity against R. solani at 200 mg L-1 with ca. 100% inhibition.
