Abstract

Weeds pose significant challenges to global agriculture, leading to significant yield losses and economic burdens. Conventional weed management strategies, particularly herbicides, are limited by the emergence of herbicide-resistant weeds and environmental concerns. Allelopathy emerges as a sustainable alternative, with sorgoleone from sorghum root exudates showing potential as a natural herbicide. Sorgoleone targets multiple physiological processes, including photosystem II (PSII), 4-hydroxyphenylpyruvate dioxygenase (HPPD), and mitochondrial electron transport. It primarily inhibits weed growth by interfering with photosynthesis and H+-ATPase activity. Its mode of action resembles synthetic herbicides, making it a potential bioherbicide. This multi-site activity reduces the likelihood of rapid resistance development relative to single-site synthetic herbicides. Sorgoleone demonstrates strong soil adsorption, undergoes active microbial degradation, and exhibits minimal leaching, supporting its potential as an environmentally sustainable weed management strategy. Furthermore, it provides effective weed control with favourable crop selectivity and can be integrated into cereal-based cropping systems and rotations without causing significant residual toxicity. Sorghum varieties with high sorgoleone content demonstrate enhanced weed control capabilities. However, sorgoleone production varies with environmental conditions and sorghum genotypes. Thus, understanding these factors is crucial for optimizing sorgoleone-based weed management strategies. This review explores the utilization of sorghum allelopathy, particularly sorgoleone, as a promising strategy for sustainable weed control. The development of sorgoleone-based bioherbicides offers an eco-friendly alternative to synthetic herbicides, exhibiting potent herbicidal efficacy against a broad spectrum of weed species. Overall, leveraging sorghum allelopathy offers a comprehensive and sustainable approach to address herbicide-resistant weeds, ensuring long-term agricultural productivity and environmental sustainability.
