Metabolite Screening From Pinus pinea Needles Reveals (+)-Isocupressic Acid as a Key Phytotoxin for Weed Management.

ABSTRACT:

Introduction

Weeds are a major threat to crop productivity, competing for essential resources and often developing resistance to herbicides, which underscores the need for novel, sustainable control strategies. The valorization of agricultural and forestry underutilized byproducts, such as plant needles, presents a promising opportunity for developing eco-friendly bioherbicides based on allelopathy.

Objectives

This study investigates the phytotoxicity of Pinus pinea needle extracts and metabolites to evaluate their potential for controlling dicotyledonous weeds.

Material and methods

The chemical characterization of extracts and isolated compounds was performed via GC-MS, NMR, and optical methods while phytotoxicity bioassays were carried out using the herbicides Pacif
