Seven new compounds, bicyclo[2,2,1]hept-5-en-2-carbonyl aromatic aldehyde hydrazones, have been synthesized and characterized by 1H NMR, IR spectra and elemental analysis. Their bio-activities have also been tested. It was found that some of them possess inhibiting activity for weeds (Sorghum vulgare), bacterials (Cucumber Botrytis cinerea) and regulating activity plant for growth.
