The present invention discloses the preparation method of cis-p-menthane-1,8-di-secondary amine compounds and their application in weed control. The preparation method is as follows: cis-p-menthane-1,8-di-Schiff base compounds are used as the raw material, and the reducing agent is added in batches into the raw material in a polar organic solvent at −10˜50° C. to react for 1˜24 h; after the reaction is complete, the reaction solution is quenched with distilled water and extracted with dichloromethane, and the extract phase is dried with anhydrous sodium sulfate, filtered with a filter and then distilled under reduced pressure to obtain crude cis-p-menthane-1,8-di-secondary amine compounds, which are purified into the pure product through recrystallization or silica gel column chromatography. The Petri dish seed germination method is used to determine the root and stem growth inhibition levels of barnyard grass incubated under different concentrations of cis-p-menthane-1,8-di-secondary amine compounds to evaluate the herbicidal activity of the compounds.
