Weed control using natural compounds

Abstract

The objective of this work was to evaluate the weed control efficacy of different plant-derived natural compounds in post-emergence applications. The treatments were alcohol+water (50% v/v), carvacrol (2.5% v/v), eugenol (2.5% v/v), thymol (2.5% v/v), trans-anethole (2.5% v/v), cinnamaldehyde (2.5% v/v), and an untreated control. The natural compounds followed a decreasing order of effectiveness: carvacrol, thymol, eugenol, trans-anethole, and cinnamaldehyde. Trans-anethole and cinnamaldehyde did not satisfactory control any of the weed species. Overall, specific plant-derived compounds are effective options for weed control.
